More Efficient LPA® Product Applications

Almost all refrigeration designers today are designing refrigeration equipment for maximum efficiencies, taking into account efficiencies gained by natural resources.  We at HY-SAVE® specialise in these areas and invite you to explore our technologies that make refrigeration systems more efficient. Our existing and recent applications are;

LPA® (Liquid Pressure Amplification) of a refrigeration or air conditioning system when minimum head pressure controls are set to reduced head pressures, thereby saving energy and increasing capacity at mild to cold outdoor temperatures. Also much improved efficiencies if liquid lines are long or have high vertical rises to the expansion valves even during hotter periods.

DX Free Cooling which incorporates LPA® pumps to circulate the refrigerant rather than using the systems compressors to provide the cooling when ambient conditions permit.

Natural Propane water chillers which rely on LPA® pumps to provide Liquid Injection, floating head pressure and DX Free Cooling during cooler periods,  substantially improving system efficiencies.

Co2 / Propane Ground Source Heat Pumps which rely on LPA® pumps to circulate refrigerant liquid underground to absorb ground-heat which changes the liquid into a vapour then drawn in by the systems compressor for compression and efficient heat during winter periods.

Co2 Sub critical LT where the LPA® pumps eliminate “flash gas” and deliver “vapour free” liquid to the cases or fixtures regardless of location and de super-heating Co2 discharge temperatures for improved performance.

Condenser de super-heating compressor discharge vapours to improve condenser performance and system efficiencies.

Two Phase Heat Transfer Systems - with natural refrigerants such as Propane used as the working fluid to transfer heat and provide cooling  in a variety of applications for higher efficiencies.
