ABSTRACT:
An air conditioning or refrigeration system includes an attached refrigerant receptacle associated with the system. During shipment or storage, the pressure within the system may exceed a selected threshold for the low pressure side. Under such circumstances, a pressure relief device automatically allows refrigerant to flow from the system into the attached receptacle, which brings the pressure within the system back to an acceptable level for the low pressure side. Various optional shutoff devices are disclosed that can be incorporated into the design to simplify receptacle removal or recycling.
