ABSTRACT:
A refrigerant fluid is entrained within a down pipe of a closed loop water flow circuit to compress the refrigerant fluid from a gaseous state to a liquid state. A separation chamber at the lower extremity of the down pipe separates the liquid refrigerant fluid from the water and the water is drawn off. The water flows upwardly through a return pipe and pump, through a pipe for reintroduction to the down pipe at the lower end thereof. The drawn off liquid refrigerant flows upwardly through a return pipe and through an expansion valve. The refrigerant fluid, converted to a mixture of vapor and liquid, called a "quality mixture of the refrigerant" by the expansion valve, flows through an evaporator to cool a medium, such as air, passing therethrough. The refrigerant fluid, flowing from the evaporator and in a gaseous state at a higher temperature, is introduced to the upper end of the down pipe for re-entrainment in the water flowing into the down pipe.
