Abstract

PURPOSE:To enhance dehumidification capacity while blocking the mutual heat transfer between a moisture absorption region and a regeneration region, by radially arranging moisture absorption/regeneration elements spaced apart to each other around a rotary shaft. CONSTITUTION:A disc shaped adsorbent 8' is equally divided into several moisture absorption/regeneration elements 16 and heat insulating materials 17 are interposed between said moisture absorption/regeneration elements 16 to separate adjacent moisture absorption/regeneration elements 16 and mutual heat transfer between said elements 16 is blocked. Each of a hygroscopic region and a regeneration region is set to integer times the open angle A of each moisture absorption/regeneration element 16, and a rotary shaft 15 is subjected to step rotary operation at every open angle A and a motor is controlled so that the heat insulating materials 17 are always positioned on the boundary of the hygroscopic region and the regeneration region at the stop position at every stepwise rotation to repeat moisture absorption and regeneration.

。As shown in Fig. 2, a dehumidifier that uses a vapor compression heat pump and an adsorbent in combination has a compressor of 1 degree, a condenser of 2 degrees, and a condenser of 2 degrees. The heat pump 5 has an expansion valve 3 and an evaporator 4 connected by piping in series, and the condenser 2 and the heat generator 4 are connected indoors and outdoors 9 via a partition wall 6.
．． An adsorbent 8 which is arranged separately from each other and rotatable around a rotating shaft 7 via a partition wall 6 is provided on the leeward side of the evaporator 4 and the condenser 2, and further on the leeward side of the condenser 8. A heat exchanger 11, which is a heat pump, has a heat absorption part 11a located in an air flow path flowing from the evaporator 2 through the adsorbent 8, and a heat radiation part 11b located in the air flow path flowing from the evaporator 4 through the adsorption agent 8. What was proposed was proposed.

８に導びくものである。The adsorbent 8 is made of zeolite, silica gel, etc.
It has a mesh-like structure that allows air to pass through, but as shown in Figure 3, due to heat transfer between the moisture absorption area 12 on the indoor side and the regeneration area 13 on the outdoor side, In the vicinity of both sides of the moisture absorption region 12, the moisture adsorption capacity decreased due to the temperature rise, and some regeneration was performed. In addition, near both sides of the regeneration zone, the temperature in the regeneration zone 13 decreases due to heat conduction to the moisture absorption zone 12, and the rotation moves to the moisture absorption zone 12 without sufficient regeneration. The width of regeneration zones 1 and 3 was reduced, reducing the dehumidification ability. In addition, in FIG. 3, 14 is a duct, which guides the air that has passed through the evaporator 4 and the condenser 2 to the adsorbent 8.
