Piping unit for air conditioning device

Abstract

A pipe unit ( 50 ) is provided for a refrigerant circuit which performs a vapor compression refrigeration cycle by circulating a refrigerant. The pipe unit ( 50 ) includes a pipe body ( 53 ) having a liquid pipe ( 51 ) through which a liquid refrigerant for the refrigerant circuit ( 40 ) flows and a gas pipe ( 52 ) through which a gaseous refrigerant for the refrigerant circuit ( 40 ) flows; and a heat insulator ( 54 ) covering each of the liquid pipe ( 51 ) and the gas pipe ( 52 ) separately. The liquid pipe ( 51 ) and the gas pipe ( 52 ), each of which is covered with the heat insulator ( 54 ), are fixed together to form a single piece. Such partial unitization of the refrigerant circuit allows for reduction in the number of days required for installation of an air conditioner.

1 . A pipe unit for an air conditioner, the pipe unit being provided for a refrigerant circuit ( 40 ) which performs a vapor compression refrigeration cycle by circulating a refrigerant, the pipe unit comprising:
 a pipe body ( 53 ) having a liquid pipe ( 51 ) through which a liquid refrigerant for the refrigerant circuit ( 40 ) flows and a gas pipe ( 52 ) through which a gaseous refrigerant for the refrigerant circuit ( 40 ) flows; and   a heat insulator ( 54 ) covering an outer periphery of the pipe body ( 53 ), wherein   the liquid pipe ( 51 ) and the gas pipe ( 52 ) of the pipe body ( 53 ) are fixed together to form a single piece.   
     
     
         2 . The pipe unit of  claim 1 , wherein
 the heat insulator ( 54 ) covers each of the liquid pipe ( 51 ) and the gas pipe ( 52 ) separately, and   the liquid pipe ( 51 ) and the gas pipe ( 52 ), each of which is covered with the heat insulator ( 54 ), are fixed together to form a single piece.
