Abstract

Vapor compression heat exchange systems (10,100) are disclosed that are designed to allow for optimal mass flow of refrigerant there through. The systems of the present invention do not employ conventional refrigerant metering devices, such as capillary tubes and expansion valves, which restrict mass flow, but rather incorporate an openly fixed orifice (40,400) in-line with the conduit (31,310) connecting the condenser (12, 120) to the evaporator (13, 130), thereby maintaining the preferential differential between the high pressure condenser side (12a,120a) and low pressure evaporator side (13a, 130a) of the system during operation. Provision of the fixed orifice (40, 100) allows for optimal refrigerant mass flow as measured by cooler compressor temperatures, cooler compressor discharge temperatures, increased heat of rejection, increased heat of absorption, and improved heating and cooling efficiency. The present invention may employ any conventional refrigerant, including the newer HFC refrigerants, such a R-410A.
