Refrigeration cycle apparatus

Abstract

In an outdoor unit of a refrigeration cycle apparatus, extension pipe connection valves are set on a valve base fixed to a partition plate and a machine chamber side panel, and an indication section is arranged on a surface of the valve base on a machine chamber front panel side. The indication section indicates, in addition to a name of refrigerant to be used, a refrigerant class, refrigerant properties, work environment guidelines, and information for access to the work environment guidelines.

1 . A refrigeration cycle apparatus for executing a refrigeration cycle, comprising:
 a compressor;   a heat source-side heat exchanger;   a pressure reducing device;   a load-side heat exchanger;   a refrigerant pipe for circulating refrigerant having at least one of a characteristic of flammability and a characteristic of toxicity by coupling the compressor, the heat source-side heat exchanger, the pressure reducing device, and the load-side heat exchanger to each other; and   an indication section arranged on at least one of a part of the refrigerant pipe, a part of a pipe support member for supporting the refrigerant pipe, a periphery of the part of the refrigerant pipe, and a periphery of the part of the pipe support member,   the indication section being configured to indicate work environment guidelines in accordance with the at least one characteristic of the refrigerant.   
     
     
         2 . The refrigeration cycle apparatus of  claim 1 ,
 wherein the refrigerant pipe includes a service port for supplying the refrigerant, and   wherein the indication section is arranged at a position of the service port.   
     
     
         3 . The refrigeration cycle apparatus of  claim 1 , further comprising:
 a heat source-side unit including the compressor and the heat source-side heat exchanger; and   a load-side unit including the load-side heat exchanger,   wherein one of both ends of an extension pipe as the part of the refrigerant pipe is connected to a heat source-side connection valve arranged at a heat source-side refrigerant pipe as the part of the refrigerant pipe arranged in the heat source-side unit and an other one of both ends of the extension pipe as the part of the refrigerant pipe is connected to a load-side connection valve arranged at a load-side refrigerant pipe as the part of the refrigerant pipe arranged in the load-side unit, and   wherein the indication section is arranged on at least one of a position of the heat source-side connection valve, a position of a heat source-side valve support member at which the heat source-side connection valve is set, a periphery of the position of the heat source-side connection valve, and a periphery of the position of the heat source-side valve support member.   
     
     
         4 . The refrigeration cycle apparatus of  claim 3 , wherein the indication section is arranged on at least one of a position of the load-side connection valve, a position of a load-side valve support member at which the load-side connection valve is set, a periphery of the position of the load-side connection valve, or a periphery of the position of the load-side valve support member. 
     
     
         5 . The refrigeration cycle apparatus of  claim 1 , wherein the indication section indicates a refrigerant name, a refrigerant class, and refrigerant properties in addition to the work environment guidelines. 
     
     
         6 . The refrigeration cycle apparatus of  claim 5 , wherein the indication section indicates information for access to the work environment guidelines.
