Noise Reduction in a Thermostatic Expansion Valve |
摘要 |
A thermostatic expansion valve assembly is provided for an air conditioning system. A thermostatic expansion valve includes a valve body having an evaporator inlet port, an evaporator outlet port, a suction line port, and a liquid inlet port. The thermostatic expansion valve controls a flow of refrigerant from the liquid line port to the evaporator inlet port. A liquid line conduit is coupled to the liquid inlet port. The liquid line conduit has at least a segment elevated above the liquid inlet port. The vapor within the liquid inlet conduit accumulates at an uppermost portion of the segment prior to a compressor startup. A substantial amount refrigerant liquid is maintained between the uppermost portion of the segment and the liquid inlet port prior to the compressor startup.
