１の凝縮器11を通るサイクルを繰り返す。The honeycomb rotor 1 that has adsorbed the water rotates slowly and moves to the air passage of the regenerated air. Since the air discharged from the first condenser 11 has a high temperature and a low humidity, the moisture in the honeycomb rotor 1 is absorbed to become a low temperature and high humidity air. It is cooled by the sensible heat exchanger 15, further cooled and dehumidified by the evaporator 13, sucked into the fan 19, heated by the sensible heat exchanger 15, and passed through the first condenser 11 to repeat the cycle.

The condenser 12 radiates heat and condenses. Refrigerant that has become liquid is squeezed
It is depressurized at 14 and goes to the evaporator 13 where it absorbs heat and evaporates to the compressor.
Return to 10. The second condenser 12 is for controlling the high pressure, and in this example, the cooling water amount is controlled by the water control valve.

る。Figure 2 shows the evaporating pressures of the single refrigerant CFC R12 (dichlorodifluoromethane) and the non-azeotropic refrigerant mixture of R114: 60% + R22: 40%. With R12 alone, the temperature is constant with respect to the evaporation pressure, but with mixed refrigerants, the temperature has a temperature range between the boiling point and the dew point for constant evaporation pressure, and the boiling point is low near the boiling point.
There is a rich gas of R22 and a rich liquid of R114 with a high boiling point, and there is a lot of liquid and a little gas. The reverse is true near the dew point.

除湿機の能力として約10％ほど大となる。成績係数もほ
ぼ同様に約１％ほど向上する。Therefore, in the evaporator and the condenser, which are in the counter flow, the pressures are almost constant, but as shown in FIG. 3, in the non-azeotropic mixed refrigerant, the temperature difference between the inlet and the outlet is the boiling point and the dew point. It occurs corresponding to the difference. Compared with R12 only by mixing the refrigerants in such a combination at an appropriate ratio, the temperature difference between the evaporator outlet air and the condenser outlet air can be increased, the evaporator outlet temperature becomes low, and the humidity also becomes low. Become.
At R114: 60% + R22: 40%, it is about 10 ° C higher than R12, the rotor regeneration side air temperature is high and the humidity is low,
The capacity of the dehumidifier is about 10% higher. The coefficient of performance also improves by about 1%.

ことができる。Although the honeycomb type has been shown as the embodiment of the present invention, the present invention is not limited only to this, and the mixed refrigerant heat pump can be used in the same manner for a two-column type that performs moisture absorption and regeneration in a batch type. . Further, it can be used as a solvent recovery device by adsorbing an organic solvent such as trichlene instead of water, and as a deodorizing device by adsorbing a malodorous substance such as phenol.

ダクトと排出ダクトの制約を受けない効果を生ず。The present invention, as described in detail above, uses a combination of non-azeotropic mixed refrigerants in which the temperature difference corresponding to the difference between the boiling point and the dew point occurs at each refrigerant inlet and outlet in the evaporator and the condenser. Since it is regenerated by a heat pump, it is energy efficient, and the running cost can be reduced as compared with the conventional regeneration by an electric heater or a steam heater. Also,
Since the recycle air is used as a closed cycle path, there is no need to introduce outside air for regeneration, and the place where the dehumidifier is installed is not affected by the restrictions of the outside air introduction duct and the exhaust duct.

合冷媒としたことを特徴とする除湿装置。1. A dehumidifying device in which moisture is absorbed by an absorbent or adsorbent, and the absorbed absorbent or adsorbent is heated to regenerate it, by forming a closed cycle path of the regeneration air. A heat pump having an evaporator that exchanges heat with the air after regeneration of the adsorbent and a condenser that exchanges heat with the air before regeneration is provided, and the refrigerant has a boiling point at each of the refrigerant inlet and outlet in the evaporator and the condenser. The dehumidifying device is a non-azeotropic mixed refrigerant having a combination that causes a temperature difference corresponding to the difference between the dew point and the dew point.
