Thermal conditioning loop for heating, ventilation and air-conditioning installation of e.g. electric car, has electric heating element arranged upstream of evaporator in flow direction of air for passenger compartment

摘要

The loop (1) has an external heat exchanger (5) arranged to be traversed by an external air flow (FE) of a vehicle for exchange of heat between a refrigerant (FR) e.g. carbon dioxide and the external air flow. An evaporator (7) and a condenser (9) are arranged to be crossed by an air flow (FH) for a passenger compartment of the vehicle for exchanging heat between the fluid and the air flow for the passenger compartment. An electric heating element (11) is arranged upstream of the evaporator in flow direction of air for the passenger compartment. An independent claim is also included for a method for controlling a thermal conditioning loop for car.
