what is the purpose of liquid pressure amplification LPA?

Liquid Pressure Amplification (LPA) is a technique used in refrigeration systems to enhance efficiency and performance. The LPA pump, such as the 809-SS-050-STD-B, is installed in the outlet line of the condenser, after the liquid receiver, to provide the stable pressure required by the expansion valve. This allows the condensing pressure to adjust or ‘float’ according to ambient temperatures, which can lead to energy savings and improved system performance.

The main purpose of LPA is to increase the liquid refrigerant pressure while maintaining the liquid temperature, providing a sub-cooled liquid delivery to the system expansion valves. This is particularly beneficial for systems experiencing liquid line pressure drops, as it helps improve the Coefficient of Performance (COP) and achieve corresponding energy savings.

The LPA pump has been a reliable component in the refrigeration industry for over 40 years, offering efficient refrigerant heat transfer, heat exchange, and latent heat of vaporization. It has been instrumental in enhancing refrigeration performance across various applications.

Liquid pressure amplification in refrigeration (LPA) involves installing a pump in the outlet line of the condenser after the liquid receiver. The LPA pump provides the stable pressure needed for the expansion valve and allows the condensing pressure (and hence compressor delivery pressure) to ‘float’ with ambient temperatures.
