摘要:
In an electric control method and apparatus for an automobile air conditioning system, an air-blend door is arranged between an evaporator and a heater within an air duct to control an amount of the cooled air flowing through the heater into a passenger compartment and to control an amount of the cooled air directly flowing into the compartment, and a refrigerant compressor for the evaporator is connected to a prime mover of the automobile when the air-blend door is opened to allow the cooled air flowing through the heater in a limited range and is disconnected from the prime mover when the air-blend door is further opened to allow the cooled air flowing through the heater beyond the limited range.
摘要:
In a refrigeration cycle of an air conditioning system of the type, in which lubricating oil for lubricating a compressor circulates through the refrigeration cycle together with refrigerant, an evaporation pressure control device is provided between an evaporator and the compressor for not only controlling the amount of refrigerant circulating through the refrigeration cycle in response to the pressure of the refrigerant out of the evaporator, but permitting the refrigerant to return to the compressor when the pressure of the refrigerant out of the evaporator is extremely decreased owing to the leakage of the refrigerant, whereby seizure of the compressor can be prevented.
