Co2 liquid refrigerant pump now rated at 80 bar

All HYSAVE® LPA® liquid refrigerant pumps have been assigned a design working

The Thermodynamic Principles of LPA

Most current refrigeration and air conditioning systems waste 20% to 40% of

New Compressor Cylinder Head & Screw Cooling Technology

Liquid Injection yes, but with an added twist; Over the past few years HY-SAVE® R&D has been extensively testing a new concept which keeps compressors cool, especially in the tropics and the Far East.

As a result compressor screw, shell and oil temperatures are substantially reduced…


Performance of the Two-Phase Ejector Expansion Refrigeration Cycle

Courtesy of Somchai Wongwises & Somjin Disawas  An ejector, or jet pump, is a device that uses a high pressure fluid to pump a low-pressure fluid to a higher pressure at a diffuser […]


Ejector Refrigeration: An Overview of Historical and Present Developments with an Emphasis on Air-Conditioning Applications

[EXTERNAL] In this paper, (2008) Stefan Elbel of Creative Thermal Solutions & Predrag Hrnjak University of Illinois at Urbana-Champaign explain;  Abstract; Ever since the renaissance of transcritical R744 systems in the late 1980s, ejectors have been considered to improve energy efficiencies. However, the invention of the ejector dates back far longer. This review paper gives an overview […]


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 […]
