• the invention also relates to an apparatus that can be built or installed around a closed hearth heating unit, for example of the chimney type or tiled stove or other stove. This unit will be referred to here as it is mounted on site.
• Heat transfer is achieved by successive changes of state of a refrigerant fluid, the evaporation of which is accompanied by heat absorption and condensation of heat generation.
• the evaporator / exchanger allows the fluid to vaporize by absorbing heat from the environment, which is returned to the outside by the condenser / exchanger when the fluid condenses.
• the compressor ensures the circulation of the fluid while increasing its pressure and its temperature, while the regulator lowers its pressure to allow its evaporation at low temperature.
• the looping repetition of these functions ensures the air conditioning of the room. It is therefore necessary to provide two devices and therefore two completely separate facilities to ensure, on the one hand the heating function as main or complementary, and on the other hand the air conditioning function outside the heating periods.
