Abstract:
A multi-function receiver for use in an air conditioning system including a refrigerant compressor, a condenser in fluid communication with an outlet of the refrigerant compressor, and an evaporator in fluid communication with an outlet of the condenser and with an inlet of the refrigerant compressor, wherein said multi-function receiver attenuates pressure fluctuations of refrigerant flowing from the evaporator to the refrigerant compressor and comprises:a body housing comprising a receiver inlet for receiving the refrigerant from the condenser and a receiver outlet for sending the refrigerant to the refrigerant compressor; a cap housing covering said body housing; a first refrigerant port defined within said cap housing and adapted to be in fluid communication with the evaporator for sending the refrigerant to the evaporator; a second refrigerant port defined within said cap housing and adapted to be in fluid communication with the evaporator for receiving the refrigerant from the evaporator; and an internal wall defining an outer cavity and an inner cavity, wherein said outer cavity is in fluid communication with said receiver inlet for receiving the refrigerant from the condenser and with said first refrigerant port for sending the refrigerant to the evaporator, and said inner cavity is in fluid communication with said second refrigerant port for receiving the refrigerant from the evaporator to attenuate the pressure fluctuations of the refrigerant received from the evaporator and with said receiver outlet for sending the refrigerant to the compressor after the pressure fluctuations have been attenuated.
