Heating / air conditioning condenser and external and adjacent evaporator for heating the evaporator external

摘要

Heating / air conditioning (IC) comprising a compressor (CP) suitable for heating and pressurizing a refrigerant fluid, an appropriate internal condenser (CDI), in heating mode, to contribute to the heating of an air called inside by exchange with said refrigerant fluid coming from said compressor (CP), a reducing external pressure (DTE) appropriate heating mode for cooling said refrigerant fluid, and an appropriate external evaporator (EE), in heating mode, for heating said fluid refrigerant from the reducing said external pressure (DTE) by exchange with air outside referred to feed to said compressor (CP), further comprising said system a contiguous external capacitor (CDE) with the outside said evaporator (EE) and appropriate, heating mode to collect fluid from said refrigerant of said internal capacitor (CDI) to feed to said network uctor external pressure (DTE) and constituting a heat source for said outer evaporator (EE) adjacent, so that the probability that the latter (EE) ice formation in the presence of outside air having a temperature is reduced low and comprising a reducing internal pressure (DTI) appropriate in cooling mode for cooling said refrigerant fluid, said system being characterized by comprising an appropriate internal evaporator (EI) in cooling mode, to cool said air inside by exchange with said refrigerant fluid from the reducing said internal pressure (DTI) and in that said external capacitor (CDE) is appropriate, in cooling mode, to precool the said refrigerant fluid coming from said compressor (CP) by exchange with said outside air, in order to feed precooling refrigerant fluid to said internal pressure reducer (DTI).
