Refrigeration cycle device and heat cycle system

Abstract

A refrigeration cycle apparatus includes a compressor, a condenser, a pressure reducing mechanism and an evaporator and use a working fluid containing a hydrofluoroolefin (HFO). The compressor, condenser, pressure reducing mechanism and evaporator are connected with a pipeline to form a refrigeration cycle. A deoxidizing portion where the working fluid is brought into contact with a desiccant or a deoxidizer is provided at any place within the refrigeration cycle.

1 . A refrigeration cycle apparatus including a compressor, a condenser, a pressure reducing mechanism and an evaporator, which are connected with a pipeline to form a refrigeration cycle, and using a working fluid containing a hydrofluoroolefin (HFO), wherein:
 a deoxidizing portion where the working fluid is brought into contact with a desiccant or a deoxidizer is provided at any place within the refrigeration cycle.   
     
     
         2 . The refrigeration cycle apparatus according to  claim 1 , wherein the deoxidizing portion is provided between the condenser and the pressure reducing mechanism. 
     
     
         3 . The refrigeration cycle apparatus according to  claim 1 , wherein:
 the deoxidizing portion is constituted as a tubular member whose opposite ends are connected to the pipeline within the refrigeration cycle, and   the deoxidizing portion includes:   an inlet-side flow surface through which a refrigerant is allowed to flow; and   a chemical agent holding portion which is provided on a downstream side of the inlet-side flow surface and holds the desiccant or the deoxidizer.   
     
     
         4 . The refrigeration cycle apparatus according to  claim 3 , wherein the inlet-side flow surface has a network-like shape. 
     
     
         5 . The refrigeration cycle apparatus according to  claim 3 , wherein:
 the deoxidizing portion further includes an outlet-side flow surface through which the working fluid is allowed to flow, and has the chemical agent holding portion between the inlet-side flow surface and the outlet-side flow surface.   
     
     
         6 . The refrigeration cycle apparatus according to  claim 5 , wherein the outlet-side flow surface has a network-like shape. 
     
     
         7 . The refrigeration cycle apparatus according to  claim 3 , wherein the chemical agent holding portion has a bag-like shape. 
     
     
         8 . The refrigeration cycle apparatus according to  claim 3 , wherein a strainer mesh for capturing sludge is provided on an upstream side of the inlet-side flow surface. 
     
     
         9 . The refrigeration cycle apparatus according to  claim 8 , wherein an area of the strainer mesh is larger than an area of the inlet-side flow surface. 
     
     
         10 . The refrigeration cycle apparatus according to  claim 1 , wherein the HFO includes HFO-1123. 
     
     
         11 . The refrigeration cycle apparatus according to  claim 10 , wherein the working fluid is a single refrigerant of HFO-1123, a mixed refrigerant of HFO-1123 and HFC-32, a mixed refrigerant of HFO-1123 and HFO-1234yf, or a mixed refrigerant of HFO-1123, HFO-1234yf and HFC-32. 
     
     
         12 . A heat cycle system, which is mounted with the refrigeration cycle apparatus according to  claim 1 .
