Abstract
The device comprises two condenser/evaporator pairs, belonging to a single refrigerant circuit, which may be selectively brought into operation and disposed at appropriate points on an air circuit having a variable configuration, the first pair being brought into operation in summer so that the evaporator cools a flow of air to be returned into the passenger space, and the second pair being brought into operation in winter so that the condenser heats a flow of air to be conveyed into the passenger space.
