Abstract
This temperature regulation apparatus comprises a heat pump () comprising a main compression circuit () for a refrigerant fluid taking heat from a cold source () and transferring it to a hot source (). The cold source () comprises a first heat exchanger () for exchanging heat between the refrigerant fluid and a coolant liquid thermally coupling the main refrigerant circuit () to a first secondary coolant circuit () capable of being selectively connected to an 'outside' heat exchanger () and to a 'cold' heat exchanger (). The hot source () comprises a second heat exchanger () for exchanging heat between the refrigerant fluid and a coolant liquid thermally coupling the main refrigerant circuit () to a second secondary coolant circuit () capable of being selectively connected to at least the outside heat exchanger () and to a “hot” heat exchanger (). The invention is applicable in particular to air conditioning a motor vehicle cabin and/or to regulating the temperature of a part of said vehicle.
