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 liquid coolant thermally coupling the main refrigerant circuit () to a first secondary coolant circuit (). The first secondary circuit () has selective connection means () for selectively connecting it to the upstream and downstream ends (A,B) of a 'heater' branch () of a cooling liquid circuit () of an exothermal part of the vehicle. The exothermal part is preferably a heat engine of the vehicle. The invention is applicable to air conditioning a motor vehicle cabin.
