Abstract

The invention relates to an air-conditioning loop (1) containing a circulating cooling fluid. Said air-conditioning loop comprises at least one compressor (2), two four-way valves (90, 100), and at least one pressure relief body (4, 5) for converting a simple air-conditioning loop into a reversible heat pump. The invention also relates to an air-conditioning system comprising such an air-conditioning loop, and to a method for implementing such a system in its different operating states.
