<p>#CMT# #/CMT# The method involves comparing temperature of refrigerant at an inlet of a compressor (9) of an air-conditioning system (8) and a threshold value, which is greater than or equal to 35 degree Celsius. The refrigerant formed at the level of a cooling exchanger (24) is condensed if the temperature of the refrigerant at the inlet of the compressor is greater than the threshold value, where the cooling exchanger directly or indirectly influences temperature of an interior air flow (3) to be sent to a cab interior of a vehicle. #CMT#USE : #/CMT# Method for controlling temperature of high or low pressure refrigerant at an inlet of a compressor of an air-conditioning loop or circuit in a heating, ventilating and/or air-conditioning installation (claimed) of a cab interior of a vehicle i.e. motor vehicle. Uses include but are not limited to control temperature of air, glycolated water, super-critical fluid such as high purity carbon dioxide (R744) or sub-critical fluid such as 1, 1, 1, 2-Tetrafluoroethane (R134a) or hydrofluoroolefin (HFO1234yf). #CMT#ADVANTAGE : #/CMT# The method enables realizing heat exchange of refrigerant at distinct points of the air-conditioning loop or circuit, thus improving the thermal efficiency of the air-conditioning loop or circuit. The method allows the temperature of the exterior air of the cab interior to improve the refrigerant condensation efficiency, thus reducing the temperature of the refrigerant at the inlet of the compressor. The method enables assuring a heating function of the cab interior by the air-conditioning loop or circuit used in heat pump mode. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a heat conditioning assembly utilized in heating mode of a cab interior for controlling temperature of refrigerant at an inlet of a compressor. 2 : Heating, ventilating and/or air-conditioning system 3 : Interior air flow 8 : Air-conditioning system 9 : Compressor 10 : Heating exchanger 24 : Cooling exchanger.</p> |
