Description
The Nordyne 664073R .073″ Piston is used as a refrigerant metering component in equipment. It regulates the flow of liquid refrigerant to the evaporator coil allowing controlled pressure drop so the refrigerant can properly expand and absorb heat during operation within HVAC systems. This component is placed inside the indoor coil assembly or metering body, where it supports balanced system performance in cooling and heating modes. It plays an essential role in maintaining correct refrigerant distribution within the evaporator circuit, especially in air conditioning units and heat pump applications, ensuring stable operation of the cooling cycle within systems.
