Moisture conditioner

Abstract

The amount of heat for thermal regeneration of an adsorber ( 80 ) is increased by making the sensible heat zone (R) for refrigerant ( 106 ) in a refrigeration cycle larger than that for R22.

1 . A humidity control system which includes an adsorber ( 80 ) for controlling the humidity of air to be processed using an adsorbent and a refrigerant circuit ( 100 ) for operating on a refrigeration cycle and thermally regenerates the adsorber ( 80 ) with heat of refrigerant ( 106 ) in the refrigerant circuit ( 100 ), 
 wherein the humidity control system is configured so that the sensible heat zone (R) for the refrigerant ( 106 ) is larger than that for R22 when compared in terms of refrigeration cycles having substantially the same discharge temperature (B).    
   
   
       2 . The humidity control system of  claim 1 , wherein the refrigerant circuit ( 100 ) is configured so that the pressure of the refrigerant ( 106 ) in the high-pressure side of the refrigeration cycle is higher than the critical pressure of the refrigerant ( 106 ).  
   
   
       3 . The humidity control system of  claim 1 , wherein the refrigerant ( 106 ) is a single refrigerant of R32 or a mixed refrigerant containing R32 in the range from 75 weight % inclusive to 100 weight % exclusive.  
   
   
       4 . The humidity control system of  claim 2 , wherein the refrigerant ( 106 ) is CO2 refrigerant.  
   
   
       5 . The humidity control system of  claim 1 , wherein 
 the adsorber ( 80 ) is composed of a first adsorption element ( 81 ) and a second adsorption element ( 82 ), and    the humidity control system is configured to run a batch operation consisting of a first behavior in which the first adsorption element ( 81 ) adsorbs moisture in a first air and the second adsorption element ( 82 ) is regenerated by heating with a second air heated up by the refrigerant ( 106 ) in the refrigerant circuit ( 100 ) and a second behavior in which the second adsorption element ( 82 ) adsorbs moisture in the first air and the first adsorption element ( 81 ) is regenerated by heating with the second air heated up by the refrigerant ( 106 ) in the refrigerant circuit ( 100 ) by alternately switching between the first and second behaviors.
