Experimental Study on the Effects of Refrigerant Inlet and Outlet Flow Directions on the Throttling Noise of Electronic Expansion Valve in Multisplit Heat Pump Air Conditioners

Experimental Study on the Effects of Refrigerant Inlet and Outlet Flow Directions on the Throttling Noise of Electronic Expansion Valve in Multisplit Heat Pump Air Conditioners

The electronic expansion valve (EEV) used in multisplit heat pump air conditioners has the structural characteristics of import and export tubes perpendicular to each other, such that the refrigerant has two forms of flow into the EEV, that is, in the direction perpendicular to the valve needle axis...
