The evaporator 4 and condenser 2 of a heat pump 5 are configured by connecting an expansion valve 3 and an evaporator 4 in series, and are separated from each other indoors and outdoors via a partition wall 6. The moisture absorbent 8 which can be rotated around 7 is placed in the evaporator 4.
There were nine installations downstream of condenser 2.

９の空気温が徐々に低下するという欠点があり之。In such a dehumidifier, humid air in a room 9 is first condensed in an evaporator 4 to remove moisture, and then the remaining moisture is removed in a moisture absorbent 8. The absorbent 8 that has absorbed moisture is rotated to the outside 10 and is regenerated by the air heated by the condenser 2. However, the air cooled and dehumidified in the evaporator 4 cannot rise to the air temperature before passing through the evaporator just by adsorbing water vapor when passing through the moisture absorbent 8, so the air temperature in the room 9 to be dehumidified gradually decreases. There is a drawback to that.

吸湿剤８の吸湿能力が低下するという問題があった。As a countermeasure for this, the air after dehumidification can be transferred to a heater or condenser 2.
However, in the former case, the cost increases due to the increase in input energy, and in the latter case, the moisture absorption capacity of the moisture absorbent 8 is reduced due to the lack of thermoelectric power for regenerating the moisture absorbent. There was a problem that the

Let it happen.

高温多湿空気より熱を汲み上げる。The heat absorbing part 11B is connected to the moisture absorbing agent 8 from the condenser 2 of the beat pump 5.
It is located in the air flow path A that flows through the moisture absorber 8, and pumps up heat from the high temperature and humid air that has passed through the moisture absorber 8.

Since the rotational direction of the moisture absorbent 80 and the flow direction of the refrigerant in the condenser 2 are opposite to each other to create counterflow, relatively low-temperature warm air hits the moisture absorbent 8 when the moisture absorbent 8 starts to be regenerated, but the wind temperature is As the moisture absorbent 8 further rotates and the regeneration progresses, the temperature gradually increases.This allows the moisture absorbent 8 to be regenerated efficiently (the regeneration speed increases in high volume areas), resulting in a high drying level. In addition, the moisture in the air that has passed through the two condensers and the moisture absorbent for regeneration is condensed and removed in the heat absorbing part 11 & of the heat pipe 11, resulting in dry air that can be recycled again. A closed cycle can be formed in which the air is circulated for regeneration.Alternatively, dry air without heat exchange may be supplied to other rooms for purposes such as heating through the heat absorbing section 116. Instead of the heat pipe 11, another heat exchanger such as a paper sheet may be used.
