Investigation Refrigeration Systems in Supermarkets – Stockholm Institute of Technology

In a conventional direct system, head pressure is normally maintained in a high level in order to avoid the generation of flash gas between the condenser and the expansion valve. Therefore, the condensing temperature is fixed neglecting the changing of ambient air temperature. While a liquid deliver pump is installed between the outlet of the condenser and upstream of the expansion valve. The liquid pressure is increased before it enters the expansion valve, and this prevents the formation of flash gas.


Replacements of HCFC and HFC with natural refrigerants

There is renewed interest in the use of natural refrigerants to replace existing HCFC and HFC compounds and also
in the use of cascade systems.

Efficiency Vermont, Reduce Food Processing Energy Use, Liquid Pressure Amplification

This publication will help you identify the cost-saving opportunities in your food processing facility and guide you in undertaking a program to improve your bottom line through energy-efficient improvements. Vermont food processing facilities are critical to Vermont’s economic future and way of life.The high energy costs associated with food processing present both challenges and opportunities. One plant recently undertook a three-year efficiency upgrade that is lowering annual electricity costs by $44,000.


CIBSE – The Quite Revolution in Chillers – Liquid Pressure Amplification

Developments in centrifugal compressors over the last five years have produced packaged water chilling equipment with considerably higher operating efficiencies than comparable compressors. The chillers are marketed in the capacity range 300 to 1,500kW; and this CPD module presents the new technology of the compressor and the chiller, together with a recent case study to illustrate the application
