EXTERNAL AND CONTIGUS CONDENSER HEATER / AIR CONDITIONER WITH EXTERNAL CONDENSER AND EVAPORATOR FOR HEATING THE EXTERNAL EVAPORATOR

摘要

A heating / air conditioning (IC) installation comprises a compressor (CP) capable of heating and pressurizing a refrigerant, a clean internal condenser (CDI), in heating mode, to contribute to the heating of a so-called internal air by exchange with the refrigerant from the compressor (CP), an external regulator (DTE) clean, in heating mode, to cool the refrigerant, and an external evaporator (EE) clean, in heating mode, to heat the refrigerant from the external expander ( DTE) by exchange with an air called outside to supply the compressor (CP). This installation (IC) also comprises an external condenser (CDE) contiguous with the external evaporator (EE) and clean, in heating mode, to collect the refrigerant fluid from the internal condenser (CDI) to supply the external expansion valve (DTE). and provide a heat source for the adjacent external evaporator (EE), so as to reduce the likelihood that the latter (EE) will frost in the presence of outside air with a low temperature.
