The above-mentioned radiant panel performs air conditioning using only heat transfer caused by heat radiation, so the air conditioning efficiency is low. Therefore, the air conditioner using such a heat radiation panel is not suitable for a place with poor heat insulation, a place with a large heat load, and a place where air enters and exits frequently. Therefore, the air conditioner using such a radiation panel has a problem of limited application range. . Moreover, the air conditioner using such a radiant panel needs to cope with problems such as condensation, and has a problem of high cost. On the other hand, air conditioners in air-conditioned spaces such as multi-air conditioners and fan coil units have a strong wind speed of cold or warm air, a sense of draft (ドラフト sense: uncomfortable feeling due to the air flow of cold or warm air), and uneven temperature The problem.

Moreover, the cooling capacity and heating capacity per unit of supply air are large (the temperature of the supply air is lowered or higher than usual), and the air volume of the supply air is reduced, so the power of the air supply can be reduced and the equipment such as pipes can be miniaturized , so cost reduction can be sought. For example, by supercooling and dehumidifying the supply air at 13°C, the amount of less wind can be achieved, and the air in the air-conditioned space can be induced to be mixed and then reheated, so as to achieve a comfortable energy-saving and cool business with a temperature and humidity of 28°C and 45% in the air-conditioned space (Cool Biz) Air Conditioning.

In this air heat source heat pump type air conditioner, a refrigerant-supply air heat exchanger 34 , a refrigerant-heat source air heat exchanger 35 , and a compressor 36 constituting a heat pump 37 are integrally provided in a casing 31 . Furthermore, it is equipped with an HP air conditioner 30 that supplies air for supply passing through the refrigerant-air heat exchanger 34 for supply air, and a steam system that humidifies the air for supply air passing through the refrigerant-air heat exchanger 34 for supply air. The humidifier 45 uses the air supply air from the HP air conditioner 30 to induce the air in the air-conditioned space S and mix it to blow it out to the air-conditioned space S in a rectified shape, and make the heat of the induced mixed air flow to the air-conditioned space S radiation induction radiation unit 1 , air supply duct 50 for inducing heat source air into the housing 31 , and exhaust duct 51 for heat source air to be discharged from the housing 31 to the outside. And the HP air conditioner 30, the air supply duct 50, and the exhaust duct 51 are installed in the ceiling C. As shown in FIG. In addition, thick arrows indicated by solid and dotted lines in each figure indicate wind directions.

The air-conditioned space S is, for example, a mansion, a dormitory of an apartment, a guest room of a hotel, a home for the elderly, individual wards of a hospital, and other various indoor spaces. In the figure, the air-conditioned space S is an example of a hotel guest room. The air used as a heat source is taken as an example of external air, and the air used as an air supply is taken as an example of return air. However, it is not limited to this and can be freely changed. Also, in the figure, the HP air conditioner 30, the air supply duct 50, and the exhaust duct 51 are concealed and installed in the ceiling. However, it may be installed on the ceiling C in the state exposed to the air-conditioned space S. The casing 31 of the HP air conditioner 30 is provided with a supply-air-side ventilation passage 32 in which a refrigerant-supply-air air heat exchanger 34 is provided, and a heat-source-side ventilation passage in which a refrigerant-heat source air heat exchanger 35 is provided. 33. The air supply-side air passage 32 and the heat-source-side air passage 33 are partitioned and formed by a partition or the like, and bend and flow air for air supply and air for heat source, respectively. By doing so, the air blowing distances of the air supply side air supply passage 32 and the heat source side air supply passage 33 are respectively extended, so that the HP air conditioner can be made more compact and noise can be reduced. In addition, shapes and structures other than those illustrated in the illustrations may be employed for the supply-side air-sending passage 32 and the heat-source-side air-sending passage 33 .

The housing 31 is formed with an air inlet 40 for air supply, an air outlet 41 for air supply, an air inlet 42 for a heat source, and an air outlet 43 for a heat source. Furthermore, the air inlet 40 for air supply and the air outlet 41 for air supply are communicated and connected through the air supply side air passage 32 . On the other hand, the heat source air inlet 42 and the heat source air outlet 43 are connected through the heat source side air supply passage 33 . The air inlet 40 for air supply communicates with the space to be conditioned S through a suction port or the like. The air outlet 41 for air supply communicates with the air-conditioned space S through the air supply passage 17 such as a duct and the induced radiation unit 1 . The air inlet 42 for the heat source passes through the air supply duct 50 , and the air outlet 43 for the heat source passes through the exhaust duct 51 , respectively communicating with the outside. An air blower 38 for air supply is provided in the air supply side air passage 32 , and an air blower 39 for a heat source is provided in the heat source side air passage 33 . In addition, the installation position of the induced radiation unit 1 is not limited to what is shown in the illustration, and can be changed freely. In addition, in the illustration, the induced radiation unit 1 is communicated with the air supply outlet 41 through a pipe, but the pipe can also be omitted, and the induced radiation unit 1 is directly connected to the casing 31 .

Dampers 47 are arranged on the air inlets and outlets of the air supply duct 50 and the exhaust duct 51 that communicate with the outdoors. In the illustration, an outdoor exhaust air blower 48 is installed on the exhaust duct 51 as a booster (Booster), and exhausts heat source air from a plurality of HP air conditioners 30 . Furthermore, heat source air is naturally introduced into the HP air conditioner 30 from outside through the air supply duct 50 . However, it can also be omitted appropriately. The induced radiation unit 1 may be omitted, and the air outlet 41 for air supply may be connected to the air-conditioned space S through a duct or an outlet (not shown). The air supply duct 50 can be omitted, and the ceiling C partition is used to naturally introduce heat source air from the outside to the HP air conditioner 30 .

The heat pump 37 has a circulating refrigerant that repeats the processes of compression, condensation, expansion, and evaporation in sequence. In the refrigerant evaporation process, heat is absorbed from the air that exchanges heat with the circulating refrigerant. The air that circulates the refrigerant for heat exchange is exothermic. The heat pump 37 includes at least a refrigerant-supply air heat exchanger 34 that performs either one of the evaporation process and the condensation process of the circulating refrigerant, and a refrigerant that performs the other of the evaporation process and the condensation process of the circulating refrigerant. - Air heat exchanger 35 for heat source, compressor 36 for compressing circulating refrigerant, decompression mechanism such as an expansion valve (not shown) for expanding circulating refrigerant, switching refrigerant - air heat exchanger 34 for air supply The refrigerant-heat source air heat exchanger 35 has switching mechanisms such as valves (not shown) for the evaporation process and the condensation process, and piping for connecting these components so that the refrigerant can circulate. The supply air (return air) taken in from the supply air inlet 40 undergoes heat exchange in the refrigerant-supply air heat exchanger 34, and is discharged from the supply air outlet 41 as cold air or warm air, and supplied to Induced Radiation Unit 1. The heat source air (external air) taken in from the heat source air inlet 42 is heat-exchanged by means of the circulating refrigerant of the refrigerant-heat source air heat exchanger 35, heat is absorbed or released, and then the air is released from the heat source air outlet 43. discharge.

The heat pump 37 may be installed on an unillustrated frame or the like, and may be integrally and freely incorporated into or removed from the casing 31 . With this, the heat pump 37 can be taken out from the casing 31 without removing the entire casing, and the refrigerant recovery and maintenance work can be easily performed, and it is also convenient to put it into it for installation. In addition, since only the heat pump 37 needs to be replaced when updating the equipment, the cost can also be reduced. The heat transfer tubes of the refrigerant-air heat exchanger 34 for air supply and the refrigerant-heat source air heat exchanger 35 are preferably elliptical tubes, but circular tubes may also be used.

It can be selected to install a damper (not shown) in the HP air conditioner 30, and the external air passes into the refrigerant-heat source air heat exchanger 35 and the return air passes into the refrigerant-air supply air heat exchanger 34. The external air passes into the refrigerant-heat source air heat exchanger 35, and the mixed air of external air and return air passes into the refrigerant-air supply air heat exchanger 34. The external air mixes the air conditioner, and the external air passes into the refrigerant-heat source Using the air heat exchanger 35 and passing the outside air into the refrigerant-supply air heat exchanger 34 is called a so-called outside air cooling air conditioner. The heat source air of the outside air is mixed with supply air such as return air, and heat is exchanged with the refrigerant-air supply air heat exchanger 34, which eliminates the need for an air conditioner for special treatment of outside air and enables energy saving. and cost savings. Also, in the case of an external air-cooled air conditioner, there is no need to operate the heat pump, and energy can be saved.

The humidifier 45 is installed in the air supply-side ventilation passage 32 . The steam is sent from the steam generator 46 to the humidifier 45 , and is sprayed into the air supply side air passage 32 to humidify the supply air passing through the refrigerant-supply air heat exchanger 34 . With the steam humidifier 45 installed in this way, it is possible to control the humidity of the air-conditioned space S in winter and increase comfort. In addition, in the case of the air supply side air supply passage 32 with a relatively long air supply distance, the vapor absorption distance can be made sufficiently large, so even a small HP air conditioner 30 can improve saturation efficiency, and the temperature control range can be increased. comfort. In addition, without providing a separate humidification space, the air supply side ventilation passage 32 can be used as a humidification space, so that the increase in size and price of the HP air conditioner 30 can be avoided. Also, the steam generator 46 may be installed either outside or inside the machine. In addition, the structure can be freely changed, and the humidification method can be freely changed to a steam method, a vaporization method, a water spray method, etc. other than those shown in the illustration. Moreover, the positions of the equipment constituting the heat pump 37, such as the refrigerant-air heat exchanger 34 for air supply, the air heat exchanger 35 for refrigerant-heat source, and the compressor 36, and the air blower 38 for air supply and the air blower 39 for heat source can also be Free to change.

The induced mixing radiation box 16 is a box body, and includes an induction opening 10 and an opening 9 formed to face an outlet 12 described below of the air supply unit 11 . Air supply air from the air supply unit 11 is blown into the induction port 10, thereby inducing the air (induction air) of the air-conditioned space S taken into the space S to be conditioned from the opening 14 described below into the interior of the induction mixing radiation box 16. At the same time, the induced air is mixed with the air for air supply to form the induced mixed air, and the induced mixed air is released to the air-conditioned space S from the plurality of openings 9 . And in the inside of the induction mixing radiation box 16, it is set to make the induction mixing air diverge and then form a rectification shape, and induce it to the air-conditioned space S through the opening portion 9, and simultaneously make the heat of the induction mixing air conduct heat to the induction mixing radiation box 16, The radiation rectifier 2 that radiates heat to the air-conditioned space S and also radiates heat to the air-conditioned space S through the opening 9 . The radiation rectifier 2 generally forms a flat rectangle, and is in contact with at least one surface of the induced mixing radiation box 16 (the side facing the air-conditioned space S in the figure), so as to facilitate heat conduction.

The induced radiation unit 1 is disposed along a corner M of the air-conditioned space S, and has an elongated overall shape extending along the corner M in which a face 20 facing the corner M is formed in a convex shape. In the present invention, the corner portion M completely includes a ceiling, a wall, a column, and other objects existing in the air-conditioned space S.

In these insertion holes, a plurality of elliptical straight pipes 99 are inserted and fixed from the normal direction of each heat transfer plate 8 . , 8 the direction of the gap. With this elliptical straight pipe 99, the strength can be increased, deformation such as bending and warping of the radiation rectifier 2 can be prevented, safety can be improved, the induced mixed air can be discharged smoothly under the condition of low pressure loss, and the air conditioner can be reduced. wind power.

The induced mixed air utilizes the component resistance of the radiation rectifier 2 and the induced mixed radiation box 16 to make the air diverge and diffuse while reducing the wind speed so that it passes through the gap between the heat transfer plates 8 and 8 and forms a rectified shape, so that the heat of the induced mixed air is evenly heat-conducted to the The entire area of the radiation rectifier 2. The openings 9 are formed at intervals across substantially the entire area of the surface 97 of the induction mixing radiation box 16 facing the air-conditioned space S. In the illustration, the opening portion 9 is formed in the shape of a long hole, but it may be a round hole or other shapes, and the position may be freely changed. In order to maximize the use of the heat radiation effect of the radiation rectifier 2 and the induced mixing radiation box 16 on the air-conditioned space S, and the heat conduction effect on the air-conditioned space S caused by the outflow of the induced mixed air, the total area of the opening part 9 is relative to the induction. The proportion of the total area of the surface 97 of the hybrid radiation box 16 is preferably set at 20 to 30% or more, but it can be freely changed. In order to realize the optimal function of the diversion and diffusion of the induced mixed air, rectification and passage, and heat conduction, the shape, number and spacing of the heat transfer plate 8 and the openings 9 are set to form an air connection with the radiation rectifier 2. Compared with the inlet side, the wind speed on the air outlet side is half or less, preferably 20 to 30% or less.

The cover 13 has a convex surface 20 facing the corner M and an opening 14 exposed in the air-conditioned space S facing the convex surface 20 . The convex surface 20 is formed in a mountain shape such as an equilateral triangle in the illustration, but may have other shapes and structures, for example, a flat shape (not shown). In the inside of the cover 13, a flat rectangular induced mixing radiation box 16 is set, and a spacer 15 is set between at least two opposite sides of the radiation box to the range of the induction port 10 and the cover 13 and the air delivery part 11 . The partition portion 15 constitutes an induced air passage as a passage for induced air. The induced mixing radiation box 16 has a structure that can be opened and closed relative to the cover 13 or attached and detached freely. In the illustration, a spacer 15 is provided so that the induced air can enter the induction opening 10 from both sides in the longitudinal direction of the induction mixing radiation box 16 . However, it is also possible to provide spacers on all four sides (the entire circumference) so that the induced air can also go around from both sides in the short side direction of the induced mixing radiation box 16 , and such changes are free. Also, the air inlet 18 for air supply is provided on one end face of the cover 13 in the longitudinal direction, but the position and number of the air inlet 18 can also be changed freely.

In the induction mixing radiation box 16 , a linear induction port 10 into which the air supply air of the air supply unit 11 is blown is formed along the center line L between two opposing side surfaces forming the partition portion 15 . Further, a linear outlet 12 for blowing out supply air blown in from the induction port 10 is formed along the induction port 10 in the air supply part 11 . The air blowing part 11 is made up of funnel-shaped partition members 19, 19 and the part surrounded by the cover 13 which become narrower and narrower from the upwind to the downwind. The members and the partition members 19, 19 constitute the air supply unit 11. The internal space of the blower unit 11 is formed to be gradually reduced from the windward side in the longitudinal direction of the blower outlet 12 to the downwind side. In the illustration, the interior of the air supply unit 11 is partitioned by the inclined plate 11a to reduce the internal space, but the air supply unit 11 itself may be reduced or reduced by other methods. Furthermore, the airflow direction adjustment mechanism G which adjusts the airflow direction is provided in the air supply part 11. As shown in FIG.

The wind direction adjusting mechanism G is formed by arranging a plurality of strip-shaped members 7 extending in a direction intersecting with the airflow direction of the supply air at intervals on the partition member 19 . In the absence of the wind direction adjustment mechanism G, as shown by the broken line arrow in Figure 8, the supply air flows in an oblique direction, and the wind direction can be adjusted as shown by the solid line arrow in Figure 8 by utilizing the resistance of the wind direction adjustment mechanism G. A direction perpendicular to the longitudinal direction of the air delivery unit 11 . The width and height of this small strip member 7 can be changed freely.

As shown in FIG. 11, the gap width HA on the short side of the linear outlet 12 is adjusted, and the blowing width adjustment mechanism A is provided to freely change the blowing wind speed, and the short side of the linear induction port 10 is provided. The gap width HB is adjusted to allow the induced wind speed to be adjusted freely. The induced width adjustment mechanism B. With this, it is possible to arbitrarily change the blowing wind speed and/or the induced wind speed, select the most suitable induced air mixing ratio for air conditioning, and further improve the air conditioning efficiency. The outlet width adjustment mechanism A includes an outlet width adjustment member 3 for increasing or decreasing the gap width HA on the short side of the outlet 12 , and a fixing unit 4 for detachably or slidably attaching the outlet width adjustment member 3 . The induction width adjustment mechanism B includes an induction opening width adjustment member 5 for increasing or decreasing the gap width HB on the short side of the induction opening 10 , and a fixing unit 6 for detachably or slidably attaching the induction opening width adjustment member 5 . The fixing units 4 and 6 are composed of well-known screw attachment members such as screws roughly indicated by dashed-dotted lines. In the illustration, the air outlet width adjusting member 3 and the induction opening width adjusting member 5 are composed of a pair of bent pieces, but the shape and structure can be freely changed. An example of the most suitable induction air mixing ratio for an air conditioner is about 6:4, but this setting can be freely changed. In addition, one or both of the blowout width adjustment mechanism and the A induction width adjustment mechanism B may be omitted.

As shown in Figure 9, as shown in the solid line thick arrow, the air for air supply is blown out from the blowout port 12 of the air supply part 11, and when entering the induced mixing radiation box 16 from the induction port 10, the gap between the blowout port 12 and the induction port 10 For negative pressure. With this, the air in the air-conditioned space S can be induced in the opening 14 as shown by the thick arrow of the short-dotted line. Then, the induced induction air enters the induction mixing radiation box 16 through the partition 15 and the induction port 10 . The induced air entering the induced mixing radiation box 16 is mixed with the air for air supply in the induced mixing radiation box 16, which is called the induced mixing air. The induced mixed air is split and diffused by the heat transfer plates 8 ... of the radiation rectifier 2 as shown by the long-dotted thick arrows, and released from the opening 9 to the space S to be conditioned in a rectified manner. These steps are repeated, and the air convection circulation is stirred between the air-conditioned space S and the induced radiation unit. When implementing cold air conditioning, air conditioning is implemented by using the induced mixed air with a temperature lower than that of the air-conditioned space S and cold and heat radiation. Also, when heating and air-conditioning is performed, the air-conditioning is performed using induced mixed air having a temperature higher than that of the air-conditioned space S and heat radiation. The supply air is set at a temperature higher than the dew point temperature of the air-conditioned space S at the time of induced mixing and at a lower absolute humidity in order to prevent dew condensation and improve air-conditioning efficiency, for example, but it can also be freely changed.

Also, as shown in FIG. 12 , a plurality of straight tubes 99 ... may be inserted at fixed intervals on each heat transfer plate 8 ... until both ends of each heat transfer tube, and inside each straight tube 99, a straight tube 99 Heat accumulator T for heat storage of induced mixed air. By means of the heat storage body T, the heat distribution over the entire area of the radiation rectifier 2 can be more reliably uniformed, so that the temperature distribution of the air-conditioned space can be made good, and more stable and comfortable air-conditioning can be realized. The thermal accumulator T should only be a material that can store heat freely and conduct heat freely, and any one of solid and fluid can be freely selected. For example, when a fluid is used, the thermal storage body T is sealed inside the straight pipe 99 . Also, in the illustration, the straight pipe 99 is oval, but it can also be a perfect circle. In the embodiment of FIG. In this way, the shape, structure, etc. of the radiation rectifier 2 can be freely changed.

Fig. 13 and Fig. 14 show that in each of the above-mentioned embodiments, on each heat transfer plate 8 of the radiation rectifier 2, the length direction of the heat transfer plate 8 is formed at regular intervals to the normal direction (perpendicular to the plane of the heat transfer plate 8) Direction) protruding and contacting the adjacent heat transfer plate 8 or even close to the short cylindrical protrusion 98, so that the prescribed opening 9 or all the openings 9 of the induced mixing radiation box 16 are opposed to the protrusion 98 . When the heat transfer plates 8 are arranged to face each other at predetermined intervals, as shown in the illustration, the central axes of the protrusions 98 overlap with the central axes of the protrusions 98 of the adjacent heat transfer plates 8 so that the protrusions 98 are arranged in a row. The protruding portion 98 is arranged linearly.

By means of this, in the opening portion 9 of the induced mixing radiation box 16, the protruding portions 98 of the heat transfer plate 8 are arranged in a row, and the opening portion 9 is shielded, so the split flow of the induced mixed air flowing to the longitudinal direction of the heat transfer plate 8 can be achieved. To promote, it is possible to reliably prevent bypassing (passing in vain) to the opening portion 9 and to uniformly transfer the heat of the induced mixed air to the entire area of the radiation rectifier 2 . In addition, in the illustration, the protruding portion 98 has an oval shape, but it may also have a circular or polygonal shape. In this case, heat radiation proceeds radially from the opening 9 to the space S to be conditioned. Simultaneously, the protruding portion 98 also exhibits the effect of promoting the diversion of the induced mixed air. Utilize the heat radiation of protrusion 98 from heat transfer plate 8 to the air-conditioned space in this way because it is carried out radially through the opening portion 9 of the induction mixing radiation box 16, so the radiation energy can reach a large range, and the air-conditioned space can be made The air temperature distribution is more uniform, and comfortable air conditioning with uniform temperature can be realized.

15 and 16 are examples of the case where the induced radiation unit 1 is disposed along the recess N of the air-conditioned space S, having an elongated overall shape extending along the recess N, in which the face facing the recess N 20 is formed in a convex shape. The cover 13 has a convex surface 20 facing the concave portion N, and has an opening 14 exposed to the air-conditioned space S facing the convex surface 20 . The other structures are the same as those of the above-mentioned embodiments, so their descriptions are omitted. In the present invention, the recess N completely includes other parts constituted by objects existing in the air-conditioned space S such as walls, pillars, and ceilings. The diagram illustrates the case where the induced radiation unit 1 is respectively disposed on the recess N of the wall and the pillar, and the corner M of the pillar and the wall. In addition, the installation position of the induced radiation unit 1 can be changed freely, and is not limited to what is shown in the figure.
