Method of Increasing Efficiency of a Refrigeration System

Abstract

Operation of a refrigeration system can be improved by adding a novel refrigerant composition comprising a mixture of activated long chain fatty acids with a polar heat transfer fluid. Activation is preferably accomplished by blending a mixture of the oils and the heat transfer fluid in a vessel containing a catalyst. Contemplated improvements can include, among other things, a reduction in power consumption, a reduction in evaporator coil condensation, or a reduction in leakage of operating fluid.

AI Technical Summary

Benefits of technology

The patent describes a method of improving the operation of refrigeration systems by adding a specific refrigerant composition to the system. The refrigerant composition can reduce power consumption, reduce evaporator coil condensation, and reduce leakage of the operating fluid from the system. The refrigerant composition involves a mixture of 1,1,1,2-tetrafluoroethane and organic oil, and it is thought that the tetrafluoroethane is complexed with the organic oil through Van der Waals forces, which can inhibit oxidation of the organic oil. The technical effects of this method include improved efficiency and durability of refrigeration systems.

Problems solved by technology

However, Van Horn and Bale do not appear to teach the use of a catalyst in providing refrigerant compositions that can be used to improve operation of a refrigeration system.

Moreover, Van Horn and Bale each fail to address the global warming concerns associated with refrigerant compositions.

Currently, HVAC (heating, ventilation, and air conditioning) and refrigeration accounts for much of the worldwide energy consumption.

Unfortunately, it has yet to be appreciated that certain complexes can be used as a refrigerant to increase energy efficiency or decrease leak rates, or that catalysts can be used to prepare such complexes.
