AI Technical Summary

Benefits of technology

The patent is about a new additive for compressor pump oil that improves its efficiency. The additive includes a mixture of organic phosphates, a type of phosphorus compound, and a hydrotreated heavy naphthenic distillate. The oil can also contain other additives like polycarboxylate based natural fatty acids, antioxidants, corrosion inhibitors, and non-ferrous metal deactivators. The technical effect is that this additive improves the performance of compressor pumps by enhancing the efficiency of the oil used in the process.

Problems solved by technology

The problem with the method is that the polar compound has chlorine in it which eventually is displaced from the compound by the presence of water, which chlorine is destructive to the metal components of the pump.

Abstract

Improvements in the efficiency of heat pump systems including refrigeration units, heating and air conditioning systems and the like using a composition that is a pump oil comprising at least a compressor oil and, a material selected from the group consisting of an organic phosphate and mixtures of organic phosphates and, a hydxotreated heavy naphthenic distillate.

Description

FIELD OF THE INVENTION [0001]This invention deals with improvements in the efficiency of heat pump systems including refrigeration units, heating and air conditioning systems and the like.BACKGROUND OF THE INVENTION[0002]For many years, efforts have been made to improve the energy efficiency of heating and cooling units which function on the heat pump principle.[0003]Once such improvement can be found in U.S. Pat. No. 4,963,280, that issued on Oct. 16, 1990 to Wilkins, et al in which there is disclosed a method of improving the efficiency of a heat pump system by introducing into the pump's oil system a polar compound which is liquid under said system's operating conditions. The problem with the method is that the polar compound has chlorine in it which eventually is displaced from the compound by the presence of water, which chlorine is destructive to the metal components of the pump.THE INVENTION[0004]Thus, what is disclosed and claimed herein is an additive for compressor pump oi...
