<p>In a heat pump associated with an internal combustion engine, the heat of exhaust gases from the engine is used, in order to drive a compressor for the refrigerant, to heat directly the circuit of the thermal fluid in the heat exchanger without direct contact. In order to obtain a good heat transmission while keeping the heat exchanger (1, 13) as small as possible, the exhaust pipe (5, 14) comprises a portion with a reduced section area inside the exchanger which causes a high gas temperature and, subsequently, a high heat transmission of the exhaust gases to the thermal fluid circuit. </p> |
