Background technology:
The floor air-conditioning technical grows up on the floor heating technical foundation gradually, and its feasibility is more and more authenticated.Have that energy-conservation, comfortableness is strong, summer in winter alliance, shift the peak value power consumption, be convenient to advantages such as single household control and heat metering.
Present floor air-conditioning system ubiquity condensation trouble, its main cause is: radiation cooling pipeline water temperature is low excessively, when the floor surface temperature is lower than indoor dew-point temperature, can produce the surface sweating phenomenon.Although the current floor air-conditioning is equipped with dehumidification system, the adjusting of its automatic control system exists and delays, and still produces condensation trouble.
Dewfall not only influences the attractive in appearance of building, and can quicken the destruction of construction material, makes ornament materials mouldy, rotten, quickens the aging of metal, and is very big to the function of use influence of building.So must take measures, avoid the generation of dewfall phenomenon.
The utility model content:
The utility model has overcome the deficiency of above-mentioned background technology, provide a kind of rational in infrastructure effectively, the floor radiant cooling of not dewfall, low energy consumption/warm and dehumidification system.
The utility model floor radiant cooling/warm and dehumidification system is made of floor radiant cooling/warm subsystem and dehumidifying subsystem; It is characterized in that: floor radiant cooling/warm subsystem is made up of moderate and high temperature heat unit and cold/warm radiant tube, and moderate and high temperature heat unit and cold/warm radiant tube constitute circulation line; The dehumidifying subsystem is made of dehumidifying unit, heat exchanger, exhaust outlet and air outlet; Exhaust outlet connects dehumidifying unit air inlet by pipeline, and the condensation heat of the air-out of dehumidifying unit, dehumidifying unit inserts heat exchanger by pipeline respectively; The heat converter air-out mouth is picked the air port by pipeline.
The utility model adopts moderate and high temperature heat, the chilled water temperature of generation suit (water temperature can reach 18 degrees centigrade), can directly send into indoor.On the one hand, solving the ground plate temperature crosses low and condensation trouble that cause; On the other hand, the moderate and high temperature heat unit has improved the coefficient of refrigerating performance of unit greatly, and send water to need not heat again, and is energy-saving and cost-reducing.Refrigeration is discrete with dehydrating unit, is about to refrigeration duty, humidity load is handled respectively, and comparing general floor cold supply system can not increase the unit power consumption, can realize temperature, wet independent control, more can finish the transition season that present air-conditioning system can't realize and dehumidify separately.As at the big but suitable spring and autumn of temperature of humidity, the user only need open the dehumidifying unit, and needn't open heat pump, makes system's design have more hommization in the time of energy-conservation.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment:
As shown in Figure 1, floor radiant cooling/warm and dehumidification system is made of floor radiant cooling/warm subsystem and dehumidifying subsystem; Floor radiant cooling/warm subsystem is made up of moderate and high temperature heat unit 1 and the cold/warm radiant tube 2 that is layed under the indoor floor, and the cold/warm radiant tube 2 of moderate and high temperature heat unit and indoor laying constitutes circulation lines.The dehumidifying subsystem is made of dehumidifying unit 3, heat exchanger 4, exhaust outlet 5 and air outlet 6.Exhaust outlet 5 is located at the indoor wall bottom, connects dehumidifying unit air inlet by pipeline, and the condensation heat of the air-out of dehumidifying unit, dehumidifying unit inserts heat exchanger by pipeline respectively; The heat converter air-out mouth is picked air port 6 by pipeline, and air outlet is arranged at indoor top board.
Winter be in the time of need heating, and the hot water of moderate and high temperature heat preparation is back to moderate and high temperature heat, the formation thermal cycle through being layed in cold/warm radiant tube 2 indoor floor under behind indoor radiant heating.
Summer be in the time of need freezing, the cold water of moderate and high temperature heat preparation through be layed in indoor floor under cold/warm up radiant tube 2 after indoor radiation cold scattering, be back to moderate and high temperature heat, form cold circulation.At this moment, because employing is moderate and high temperature heat, the cold water temperature in the inlet chamber can be controlled in 18 degrees centigrade, has reduced the possibility of dewfall.Simultaneously, the indoor section humid air enters the dehumidifying unit through exhaust outlet 5, carries out cooling and dehumidifying; Air after the dehumidifying enters heat exchanger through pipeline 4 again, carry out heat exchange with the wind that is loaded with dehumidifying unit condensation heat here, be loaded with the air quantity of the wind of dehumidifying unit condensation heat by regulation and control, regulate the temperature of mixing wind in the heat exchanger, reach suitable wind pushing temperature (about 21 degree) after that air outlet 6 is sent into is indoor, so finish dehumidifying work.Owing to be provided with the dehumidifying subsystem to indoor air dehumidification, reduced floor and cold/possibility of dewfall when warm radiant tube 2 freezes more.In addition, at the indoor humidity adjusting material that is used, stop the dewfall phenomenon that produces because of the delay of dehumidifier unit automatic control system.Need to prove,, can close floor radiant cooling/warm subsystem, dehumidify separately by the dehumidifying subsystem in season in spring and autumn.
The utlity model has remarkable energy saving effect.At first, coefficient of refrigerating performance is significantly improved, and this unit COP can reach more than 5.2; Secondly, reduced the operation energy consumption of capital equipment.
The utility model is implemented on a family 200m
2Villa, in Nanjing area operation, each in season operation energy consumption and residential central air-and general floor cold supply system contrast such as following table:
With regard to summer, the residential central air-energy consumption reaches 20KW; General floor air-conditioning reaches 11.2KW; The utility model energy consumption only is 5.4KW.With regard to winter, it is 3.1KW only that the utility model energy consumption maintains an equal level with general floor air-conditioning, is lower than residential central air-.In addition, the utility model more can finish like product can't realize dehumidify separately in transition season, energy consumption also only has 2.7KW.
Native system power consumption in summer only is 48% of a general floor air-conditioning, only is 27% of residential central air-.On this basis, supposing to have summer 80 days needs the start group, opens every day 6 hours, then compares general floor air-conditioning, can save electric weight 2784 degree whole summer, compares residential central air-and more can save 7008 degree.Energy-conservation achievement is remarkable.
Except being applicable to family life, can also be widely used in buildings such as hotel, venue, office building, be expected to produce huge economic and social benefit.
