Abstract

Provided is an air conditioning/hot water supply system having high operational efficiency. An internal heat exchanger (15) has: a primary heat transfer pipe (15a) for forming a part of the annular circuit of a refrigerant circuit (10) for air conditioning; and a secondary heat transfer pipe (15b) connected to piping (P) branched from the annular circuit through a pressure reduction device (16). The pressure reduction device (16) reduces the pressure of a first refrigerant flowing therein from the piping (P) depending on an operation mode and causes the first refrigerant the pressure of which has been reduced to flow toward the secondary heat transfer pipe (15b) thereby cooling the first refrigerant flowing through the primary heat transfer pipe (15a).
