Abstract: A liquid cooled refrigerant condenser comrpises an enclosure with an upper chamber and a lower chamber forming a partitioned liquid reservoir containing cooling liquid. The enclosure contains a refrigerant condensing manifold with an inlet pipe for receiving refrigerant gas from a compressor, an intermediate portion disposed within the lower chamber and submerged in the liquid, and an outlet portion for conducting the refrigerant gas to an evaporator coil. The manifold inlet pipe is coiled in a square helical coil above the liquid level in the reservoir. A blower mounted at the top of the enclosure directs the flow of air onto the liquid reservoir at sufficient velocity to entrain some of the liquid and direct a mixture of liquid and air onto the coiled inlet pipe of the manifold to remove heat from hot refrigerant gas passing through the coiled manifold.
