Embodiment 1

[0023] Such as figure 1 As shown, the refrigeration and constant humidity air conditioner of the present invention is mainly composed of a compressor 1, an outdoor heat exchanger 2, a throttle valve 3, a hydrophilic heat exchanger 5, and a hydrophobic heat exchanger 6. The hydrophilic heat exchanger 5 and the hydrophobic heat exchanger The heater 6 is connected to the main circuit through a two-position three-way valve 4, the common port of the two-position three-way valve 4 is connected to the main circuit, and its two branches are connected to the hydrophilic heat exchanger 5 and the hydrophobic heat exchanger. Heater 6 on. When the humidity sensor installed in the room detects that the indoor humidity is lower than the set value, the two-position three-way valve 4 is energized, the a and c channels of the two-position three-way valve 4 are connected, and a and b are blocked, and the refrigerant passes through the pipeline and drains The heat exchangers 6 are connected, and...

Embodiment 2

[0026] Such as figure 2 As shown, the refrigeration constant humidity air conditioner of the present invention is mainly composed of a compressor 1, an outdoor heat exchanger 2, a throttle valve 3, a hydrophilic heat exchanger 5, and a hydrophobic heat exchanger 6, and the hydrophilic heat exchanger 5 is connected in series An electromagnetic shut-off valve 7 is connected to the main circuit in parallel with the drain heat exchanger 6. When the humidity sensor installed in the room detects that the indoor humidity is lower than the set value, the electromagnetic shut-off valve 7 is not powered on, and the drain heat exchanger 6 works. Hydrophilic heat exchanger 5 does not work. Since the surface of hydrophobic heat exchanger 6 is coated with a superhydrophobic material film, that is, a nanomaterial layer, condensed water will not be generated on the surface of hydrophobic heat exchanger 6, so that the water in the indoor air There is no loss of steam, thereby ensuring that th...

Embodiment 3

[0029] Such as image 3 As shown, the difference between this embodiment and Example 2 is that an electromagnetic shut-off valve 8 is connected in series with the drain heat exchanger 6 . When the humidity sensor installed indoors detects that the indoor humidity is low, the electromagnetic shut-off valve 8 is energized, the electromagnetic shut-off valve 7 is not powered, and the hydrophobic heat exchanger 6 connected with the electromagnetic shut-off valve 8 works, while the hydrophilic heat exchanger 5 does not work, because the surface of the hydrophobic heat exchanger 6 is coated with a superhydrophobic material film, that is, fluorocarbon resin, no condensed water will be generated on the surface of the hydrophobic heat exchanger 6, so that the water vapor in the indoor air will not be lost, thereby ensuring indoor Humidity does not decrease. When the humidity sensor installed in the room detects that the indoor humidity is high, the electromagnetic shut-off valve 8 wil...

Abstract

The invention relates to a constant humidity method for a refrigerating air conditioner and a refrigerating constant humidity air conditioner for realizing said method. Two heat exchange units are arranged as an indoor heat exchange part of the air conditioner. A hydrophobic heat exchanger is formed by coating super hydrophobic material film on surface of one heat exchange unit, and a hydrophilic heat exchanger is formed by coating super hydrophilic material film on surface of another heat exchange unit. When the indoor humidity is not above the set value, refrigeration is performed by the hydrophobic heat exchanger, and the hydrophilic heat exchanger is switched off; When the indoor humidity is above the set value, the hydrophilic heat exchanger is started up, and refrigeration and dehumidification are performed.

Description

technical field [0001] The invention relates to a refrigeration and air-conditioning constant-humidity method, and also relates to a refrigeration and constant-humidity air-conditioner produced by the method. Background technique [0002] Generally, when the air conditioner is cooling, condensed water will be generated on the evaporator. As long as the system is in the cooling state, condensed water will definitely be generated. At present, there is no effective method for suppressing the generation of condensed water. In areas with a drier climate, while the air conditioner is cooling and cooling, a large amount of water vapor in the indoor air is also removed, resulting in drier indoors and lower humidity, requiring humidification. Usually the range of relative humidity that people feel more comfortable is 40-60%. When the relative humidity is low, it will not only make people feel uncomfortable, but also cause some diseases; when the relative humidity is high, it will be ...
