Abstract
A heating/cooling device (1) is proposed for vehicles, in particular motor vehicles, with a compressor (3), a refrigerant circuit (5), a gas cooler (7), an evaporator (9), and with an expansion valve (37) arranged between the gas cooler (7) and evaporator (9) in the refrigerant circuit (5). The heating/cooling device (1) is distinguished in that the gas cooler (7) or the evaporator (9) is coupled with a liquid coolant circuit (13, 23) which cooperates with an interior heat exchanger (19) or an external air heat exchanger (27), or that the gas cooler (7) and the evaporator (9) are each coupled with an its own liquid coolant circuit (13, 23), wherein one of the liquid coolant circuits (13, 23) cooperates with the interior heat exchanger (19) and the other liquid coolant circuit (23, 13) cooperates with the external air heat exchanger (27).
