TEMPERATURE CONTROL SYSTEM FOR A MOTOR VEHICLE, CORRESPONDING HEATING, VENTILATION AND/OR AIR-CONDITIONING EQUIPMENT, AND CORRESPONDING CONTROL METHOD

摘要

The invention relates to a system for controlling the temperature of the air flow in a motor vehicle comprising a coolant circuit (3), wherein the coolant (3) includes a condenser (15) and a sub-cooling exchanger (13) for the coolant, arranged downstream from the condenser (15) in the direction of flow of the coolant. According to the invention, said coolant circuit (3) further includes at least one branch (34, 134) for bypassing the sub-cooling exchanger (13), enabling the coolant to flow while bypassing the sub-cooling exchanger (13). The invention also relates to heating, ventilating and/or air-conditioning equipment including such an air-flow conditioning system and to a method for controlling this air-flow conditioning system.
