Making Refrigeration More Efficient with LPA®
HY-SAVE® technology delivers significant energy savings that pay back promptly by making refrigeration more efficient. For DX applications considerable savings can be made, generally up to 40%, ambient temperatures permitting. By simply reducing the condensing temperature from 32°C to 18°C it will provide a saving of approximately 23%. As energy costs continue to rise, the […]

The Thermodynamic Principles of LPA
Most current refrigeration and air conditioning systems waste 20% to 40% of the electrical power used. The LPA® pump can save most of this power. How is my power being wasted? Present day designs with head pressure controls were developed some 65 years ago. Higher head pressures were designed into a system so it would […]

An Introduction of a Transcritical Co2 Refrigeration Cycle
This paper describes the transcritical refrigeration cycle utilizing CO2 as working fluid which is composed with Gas cooler, Inter cooler, Suction Line Heat Exchanger, Capillary tube and Rolling Piston type 2-Stage CO2 Compressor. The adoption of the Inter cooler between 1st discharge and 2nd suction reduced the 2nd discharge gas temperature. The adoption of the […]
