Estimating the term…
A blowoff valve assembly includes a diaphragm separating a refrigerant connection from an ambient port open to the atmosphere. The refrigerant connection is preferably connected to air conditioning system such that the diaphragm is in contact with refrigerant from the system. The diaphragm is deflectable based on the pressure of the refrigerant and is operatively connected to a switch. When pressure of the refrigerant drops to a predetermined level, the diaphragm deflects to activate the switch. Additionally, the assembly also includes a detonable squib that explodes and ruptures the diaphragm, allowing the refrigerant to flow from the refrigerant connection to the atmosphere. Additional features, such as sensors for detecting refrigerant outside of the system, a collision subsystem, and an associated controller are also disclosed.
