Refrigerant cycle system for vehicle air conditioner

InactiveUS6266967B1Prevents the first evaporator from frostingAvoid deficienciesCompressorAir-treating devicesContinuous operationLubrication
In a refrigerant cycle system for a vehicle air conditioner, when a continuous operation time of a compressor elapses a predetermined time after the compressor operates, operation of the compressor is forcibly interrupted so that a refrigerant pressure at a suction side of the compressor is changed. Thus, even when the compressor operates continuously in a long time when only a front evaporator operates among front and rear evaporators, the refrigerant pressure at a low-pressure side is forcibly changed so that a rear thermal expansion valve of the rear evaporator is forcibly opened. As a result, lubrication oil staying in the rear evaporator and a low-pressure pipe is introduced into the suction side of the compressor by a refrigerant flow due to a valve opening of the rear thermal expansion valve of the rear evaporator.

Motor Vehicle and Control Method of Motor Vehicle

In a hybrid vehicle of the invention, when a voltage level E of a low-voltage battery exceeds a preset alert reference value Eth1 (step S115), fueling control activates a negative pressure pump with a preset amount of power consumption for standard fuel vapor treatment (step S125). When the voltage level E of the low-voltage battery exceeds a low charge reference value Elow but is not higher than the preset alert reference value Eth1 (steps S115 and S120), the fueling control activates the negative pressure pump with a smaller amount of power consumption (step S130). When the voltage level E of the low-voltage battery is not higher than the low charge reference value Elow (step S120), the fueling control inactivates the negative pressure pump (step S135). Such control enables at least a voltage of the low charge reference value Elow to be reserved in the low-voltage battery even after regulation of internal pressure of a fuel tank.
