Refrigeration cycle apparatus

Abstract

A refrigeration cycle apparatus having a housing in which at least a portion of a refrigerant circuit through which refrigerant circulates is located, the housing forming an outer shell and having a front side portion, the front side portion being removable, wherein the at least portion of the refrigerant circuit includes a condenser, a pressure container in which the refrigerant is reserved, a first pipe through which the refrigerant flows, the first pipe connecting the condenser and the pressure container, and a pressure relief device having a fusible plug, provided on the first pipe, and configured to release the refrigerant when a pressure in the first pipe reaches a predetermined pressure, and a portion of the first pipe, on which the pressure relief device is provided, is located beside the front side portion in the housing.

1 . A refrigeration cycle apparatus having a housing in which at least a portion of a refrigerant circuit through which refrigerant circulates is located, the housing forming an outer shell and having a front side portion, the front side portion being removable, wherein
 the at least portion of the refrigerant circuit includes   a condenser,   a pressure container in which the refrigerant is reserved,   a first pipe through which the refrigerant flows, the first pipe connecting the condenser and the pressure container, and   a pressure relief device having a fusible plug, provided on the first pipe, and configured to release the refrigerant when a pressure in the first pipe reaches a predetermined pressure, and   a portion of the first pipe, on which the pressure relief device is provided, is located beside the front side portion in the housing.   
     
     
         2 . The refrigeration cycle apparatus of  claim 1 , wherein the fusible plug has an outer circumferential portion provided with a male thread. 
     
     
         3 . The refrigeration cycle apparatus of  claim 1 , wherein the pressure relief device has a branch pipe connecting the fusible plug and the portion of the first pipe. 
     
     
         4 . The refrigeration cycle apparatus of  claim 3 , wherein the branch pipe includes a curved portion. 
     
     
         5 . The refrigeration cycle apparatus of  claim 4 , wherein the curved portion of the branch pipe is formed such that a tip end portion of the branch pipe extends in a direction in which the portion of the first pipe extends. 
     
     
         6 . The refrigeration cycle apparatus of  claim 3 , wherein the branch pipe is a capillary tube. 
     
     
         7 . The refrigeration cycle apparatus of  claim 6 , wherein the at least portion of the refrigerant circuit includes
 a compressor configured to compress the refrigerant,   a second pipe connecting the compressor and the condenser, and   a high-pressure switch provided on the second pipe.   
     
     
         8 . The refrigeration cycle apparatus of  claim 2 , wherein the pressure relief device has a branch pipe connecting the fusible plug and the portion of the first pipe. 
     
     
         9 . The refrigeration cycle apparatus of  claim 8 , wherein the branch pipe includes a curved portion. 
     
     
         10 . The refrigeration cycle apparatus of  claim 9 , wherein the curved portion of the branch pipe is formed such that a tip end portion of the branch pipe extends in a direction in which the portion of the first pipe extends. 
     
     
         11 . The refrigeration cycle apparatus of  claim 8 , wherein the branch pipe is a capillary tube. 
     
     
         12 . The refrigeration cycle apparatus of  claim 11 , wherein the at least portion of the refrigerant circuit includes
 a compressor configured to compress the refrigerant,   a second pipe connecting the compressor and the condenser, and   a high-pressure switch provided on the second pipe.
