Problems solved by technology

[0004] Furthermore, in such an air conditioner, more energy is consumed in accordance with the defrosting operation, so that the operating efficiency of the air conditioner decreases.
In addition, during the defrosting operation, the load on the air conditioner after the defrosting operation increases due to an increase in the temperature inside the refrigerator, and as a result, the power consumption of the air conditioner increases.
[0005] In addition, in such an air conditioner, for example, when a compressor whose rotation speed is controlled is used, as the cooling load in the middle period of cooling (rainy season, autumn, etc.) decreases, the rotation speed of the compressor decreases to follow the load.
At this time, the evaporating temperature of the evaporator rises and the sensible heat of the room is removed but the latent heat of the room is not removed, so that the relative humidity of the room rises, and people in the air-conditioned space feel uncomfortable.

Abstract

The air conditioner (100) has: a refrigerant circulation circuit (A); a desiccant material arranged between the first heat exchanger (13) and the second heat exchanger (15); The air flow through the first heat exchanger (13), the desiccant material and the second heat exchanger (15) sequentially; and the control device (90), which controls the flow path switching device to switch the first operation mode and the second operation mode mode, the first mode of operation makes the first heat exchanger (13) play the role of condenser or radiator, and makes the second heat exchanger (15) play the role of evaporator, desorbs the desiccant material Moisture, the second operation mode makes the first heat exchanger (13) play the role of evaporator, and make the second heat exchanger (15) play the role of condenser or radiator, make the desiccant material absorb water, the second The second heat exchanger (15) has a sliding effect of dew condensation water when the same amount of dew condensation water adheres in the first region which is the lowermost region in the direction of gravity than the region which is not the lowest in the direction of gravity The area where the second area is strong.

Description

technical field [0001] The invention relates to an air conditioner with dehumidification function. Background technique [0002] As a conventional air conditioner, there is an air conditioner including a refrigerant circulation circuit and a defrosting heater in which a compressor, a condenser, an expansion valve, and an evaporator are sequentially connected by piping, for example. In the refrigerant circulation circuit, the refrigerant compressed by the compressor becomes high-temperature and high-pressure gas refrigerant, which is sent to the condenser. The refrigerant flowing into the condenser is liquefied by releasing heat to the air. The liquefied refrigerant is decompressed by the expansion valve, becomes a gas-liquid two-phase refrigerant, and flows into the evaporator. The gas-liquid two-phase refrigerant is vaporized by absorbing heat from the surrounding air in the evaporator, and is sucked into the compressor. [0003] When such an air conditioner is used in, ...
