CN201106916Y - A kind of radiant plate for dredging and dew condensation - Google Patents

Abstract

The utility model provides a dew-draining radiant plate, which includes a plate body, and the surface of the plate body facing the room is made with several arranged micro-grooves and at least one condensate groove connected with the micro-grooves. . The "condensation water" on the surface of the radiant plate first accumulates in the micro grooves under capillary action, and then uses the drainage of the inner surface slope of the micro grooves or the self-weight of the "condensation water" to dredge the "condensation water" to communicate with the radiant plate Concentrated recovery in the connected condensate tank. This kind of dew-draining radiant panel not only solves the problem of dew dripping in the room, but also ensures a dry indoor environment, stabilizes the radiation cooling load, and ensures the quality of the air conditioner. The structure is simple, the manufacturing cost is low, and the dew condensation effect is good, and it is suitable for places such as radiation cooling and air conditioning systems.

Description

A kind of radiant plate for dredging and dew condensation

technical field

The utility model relates to a device of an air-conditioning system, more specifically, relates to a dew-draining radiation plate

technical background

Traditional air-conditioning and refrigeration systems are facing many insurmountable problems such as energy saving and deterioration of indoor air quality (IAQ) Cooling and air-conditioning systems mainly have the advantages of energy saving, peak energy consumption, good thermal comfort, no blowing sensation, greatly improved indoor air quality, building space savings, simple and effective area control, etc. However, the radiant cooling and air-conditioning systems in the prior art, when water When the temperature is low or the indoor humidity is high, dew condensation is likely to occur on the surface of the radiant panel. In addition, when the doors and windows are opened, the outdoor hot and humid air enters the room, and when it comes into contact with the low-temperature radiant panel, condensation is also likely to occur. Indoor dripping greatly affects the indoor dry environment. In order to prevent condensation, the method of making the temperature of the water flowing through the radiant plate higher than the indoor condensation temperature is usually adopted. Although this method is effective in preventing condensation, it is It will lead to an increase in the circulation rate of the refrigerant, thereby increasing the energy consumption of refrigerant transportation, and at the same time, due to the increase in the surface temperature of the radiant panel, the radiant cooling load will decrease, resulting in a decrease in the quality of the air conditioner.

Utility model content

Technical problem: The purpose of this utility model is to solve the problems existing in the radiant panel in the above-mentioned radiant cooling air-conditioning system, and to provide a radiant panel of a dew-draining type.

Technical solution: In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is as follows:

A dew-draining radiant plate, comprising a plate body, the surface of the plate body is manufactured with several arranged micro-grooves and at least one condensation groove connected with the micro-grooves, so that the micro-grooves in the micro-grooves Water sinks in the condensation water tank.

Wherein, the micro-grooves are arranged on the surface of the plate body facing the room, the cross-section of the micro-grooves is arched, and the two ends of the micro-grooves are in communication with the condensate grooves provided.

Or the microgrooves are arranged vertically on the surface of the plate body facing the room, and communicate with the condensate groove arranged at the lower end.

The microgrooves are preferably arranged at equal intervals.

Beneficial effects: the dew-draining radiant plate adopting the structure of the utility model, because several micro-grooves and at least one condensate groove connected with the micro-grooves are arranged on the surface of the plate body, so that the "condensation water" in the Under the capillary action, it first accumulates in the micro-groove, and then uses the drainage of the inner surface slope of the micro-groove or the self-weight effect of the "condensation water" to guide the "condensation water" to the condensation water tank connected to the radiant plate for centralized recovery. In this way, the solution to the problem of "condensation" existing in radiant panels is changed from "passive" to "active", which not only solves the problem of dripping condensation water in the room, ensures a dry indoor environment, but also stabilizes the radiation cooling load, ensuring air conditioning quality.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

In order to solve the above technical problems, the utility model provides a dew-draining radiant plate, which includes a plate body 1, and the surface of the plate body 1 is manufactured with a number of arranged micro-grooves 2 and at least one of the micro-grooves. The condensation water grooves 3 connected with the grooves 2 make the water in the micro grooves 2 converge in the condensation water grooves 3 .

As shown in Figure 1, for a ceiling-mounted radiant panel, a number of microgrooves 2 arranged at equal or unequal intervals are manufactured on the surface of the radiant panel body 1 facing the room, and the groove depth of the microgrooves 2 is from the center to the The edge is gradually lowered, so that the cross section of the plate body 1 is arched, and the two ends are provided with condensation water grooves 3 connected with it. The drainage function of the slope of the inner surface of the ditch 2 guides the "condensation water" to the condensation water tanks 3 at both ends of the radiant plate for centralized recovery.

As shown in Figure 2, for a wall-type radiant panel, micro-grooves 2 are made vertically on the surface of the radiant panel body 1 facing the room at equal or unequal intervals, and the lower end is provided with a condensation groove 3, when the surface of the radiant panel When dew condensation occurs, dew condensation water first accumulates inside the micro-groove 2 under capillary action, and then flows into the condensation water tank 3 arranged at the lower end of the radiant plate by its own gravity for centralized recovery.
