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. |
