Specifically, the present invention relates to a new dehumidifying device that prevents liquid from returning to the compressor. By heating the indoor air that has been cooled and dehumidified in the evaporator using this high-temperature, low-pressure gas cold soot and dehumidifying the indoor air, the liquid refrigerant remaining in the evaporator is removed when the compressor is restarted. This prevents the liquid from being directly sucked into the compressor and prevents liquid from returning to the compressor.

The indoor fan 37 is activated to operate the compressor 31.
is searching for. However, in this type of dehumidification device, when the compressor 31 and indoor fan 37 are stopped using the operation switch, liquid refrigerant remains unevaporated in the evaporator 35, and the compressor 31 and indoor fan 37 are then restarted. When the dehumidifying operation is restarted after startup, the liquid refrigerant remaining in the evaporator 35 exchanges heat with the indoor air induced by the indoor fan 37, and part of it evaporates and becomes a gas medium, but the remaining liquid refrigerant remains in the evaporator 35. There was a problem in that the refrigerant was sucked into the compressor 31 as it was, and the liquid returned to the compressor 31. The present invention was invented in an attempt to improve the above-mentioned problems, and by heating the low-pressure gas refrigerant evaporated in the evaporator with the high-temperature refrigerant on the high-pressure side, "the indoor air cooled and dehumidified by the evaporator is By reheating the cooled and humidified indoor air using this high-temperature, low-pressure gas refrigerant and dehumidifying the indoor air, the system prevents liquid from returning to the compressor when the compressor is reinstalled.

うな熱交換関係にしている。The heat exchanger 2 has a double-tube structure having two passages, an outer passage 2a and an inner passage 2b, as shown in FIG. 1, and heat exchange between the two passages 2a and 2b. The gas-liquid mixed refrigerant flowing out from the condenser 21 flows into the outer passage 2a, and as the refrigerant condenses and liquefies, the low-pressure gas refrigerant flowing out from the evaporator 4 flows into the inner passage 2b. A heat exchange relationship is established in which the soot is allowed to flow and the lining is heated to a higher temperature than the indoor air which has been cooled and dehumidified by the evaporator 4.

「膨張弁３に至る。This gas-liquid mixture of high-pressure soot flows into the heat exchanger 2, and while passing through the outer passage 2a of the heat exchanger 2, it is supercooled by the low-pressure and low-temperature gas medium flowing out from the evaporator 4 ( Point C: Reaching expansion valve 3.

It evaporates while being cooled and dehumidified, and flows into the heat exchanger 2 as a gas cooler with a certain degree of superheating.

となって再熱器５に流入する。Next, the low-pressure gas refrigerant that has entered the heat exchanger 2 is heated by the above-mentioned gas-liquid mixed high-pressure refrigerant flowing out from the condenser 21 while flowing through the inner passage 2b, and is cooled and dehumidified in the evaporator 4. The low-pressure gas, which is hotter than the indoor air, flows into the reheater 5 as a point.
ここで、この高温の低圧ガス冷煤は前記冷却除湿された
室内空気と熱交換し、該室内空気を再熱しながら冷却さ
れた後（点ト）、圧縮機１に吸入される。Here, this high-temperature, low-pressure gas cold soot exchanges heat with the cooled and dehumidified indoor air, is cooled while reheating the indoor air, and is then sucked into the compressor 1.

まで冷却されることがない。On the other hand, indoor air is cooled and dehumidified in the evaporator 4, then reheated in the reheater 5, and then returned indoors to perform a dehumidifying operation.
Note that the low-pressure gas cold soot flowing through the reheater 5 is transferred to the evaporator 4.
Heat exchanges with indoor air that has been cooled and dehumidified, and the indoor air cools the air, so it is not cooled to a temperature lower than the indoor air, that is, it is not cooled to an evaporation temperature that is even lower than the indoor air. .

ることなく「液冷媒のまま蒸発器４から流出する。Therefore, the low-pressure gas medium flowing through the reheater 5 is sucked into the compressor 1 in a gaseous state without being liquefied. by the way,
Compressor 1, indoor fan depending on the operation switch etc. When the evaporator 4 is stopped, the liquid-cooled soot in the evaporator 4 remains unevaporated, but when the compressor 1 and the indoor fan 7 are restarted, the liquid-cooled soot in the evaporator 4 is turned over by the indoor fan 7. Most of the soot evaporates through heat exchange with the indoor air and becomes a gas liner. However, the liquid cooled soot remaining on the outlet side of the evaporator 4 does not evaporate and remains in the evaporator as a liquid refrigerant. It flows out from 4.

It is heated by the refrigerant and completely evaporates, becoming a high-temperature gas cold soot and flowing to the reheater 5.

In the above embodiment, a condenser 2 is installed between the compressor 1 and the heat exchanger 2.
1, a part of the heat of the high-pressure gas cooler discharged from the compressor turtle is released from the condenser 21 to the outside, and the amount of heating for heating the low-pressure gas cold soot flowing through the heat exchanger 2 is reduced. , the amount of reheating indoor air in the reheater 5 is made smaller than the amount of cooling heat in the evaporator 4.

配管で接続できるセパレ−ト型除湿装置とし得る。That is, although dehumidification operation with a slight cooling effect is being performed, the amount of heat emitted by the condenser 21 is reduced or eliminated, the amount of heating of the low-pressure gas refrigerant in the heat exchanger 2 is increased, and the amount of heat released by the reheater 5 is increased. If the amount of reheating of the indoor air is made larger than the amount of cooling heat in the evaporator 4, a dehumidifying operation with a heating effect can be performed.
Methods for reducing or eliminating the amount of heat released from the condenser 21 include providing a bypass circuit that bypasses part or all of the condenser 21, controlling the rotation speed of the outdoor fan 8, or eliminating the condenser 21. There are various known means such as. Furthermore, the arrangement order of the condenser 21 and the heat exchanger 2 is as follows:
It goes without saying that the present invention is not limited to the above embodiments, and that the same effect can be obtained even if the order is reversed, and is within the scope of the present invention. Further, as described above, when the condenser 21 and the heat exchanger 2 are provided and the condenser 21 is disposed between the compressor 1 and one passage 2a of the heat exchanger 2, the condenser 21 and the compressor Configure machine 1 as an outdoor unit,
If the heat exchanger 2, expansion valve 3, evaporator 4, and reheater 5 are configured as an indoor unit, a separate type dehumidifier can be obtained in which the indoor and outdoor units can be connected with two pipes.

a or the condenser 21 and the passage 2a to condense and liquefy the high-pressure gas cold soot discharged from the compressor 1, and the evaporator 4 to evaporate the low-pressure liquid cold soot and cool and dehumidify indoor air; The other passage 2b heats the low pressure gas refrigerant to a higher temperature than the cooled and dehumidified indoor air, and the reheater 5 cools the low pressure gas refrigerant and reheats the cooled and dehumidified indoor air. Therefore, even if the compressor 1 is restarted and the liquid refrigerant that remained in the evaporator 4 when the compressor 1 was stopped flows out of the evaporator 4 without being evaporated, the heat exchange at the outlet side of the evaporator 4 is The refrigerant is heated in the reheater 5 and completely evaporated to become a low-pressure gas refrigerant, and the refrigerant exchanges heat with indoor air that has been cooled and dehumidified in the evaporator 4.
It is not cooled below the evaporation temperature of the evaporator 4 and is not liquefied in the reheater 5.
