A discovery – condenser drainage

Defying the Laws of Gravity. Condenser drainage. The video shows a liquid receiver installed 20 feet above the outdoor condenser. The study and behaviour of liquid refrigerant flowing from an air-cooled condenser into a liquid receiver has been provided. A liquid receiver and LPA® pump was lifted to roof top to simulate a 20′ condenser […]

Liquid Pressure Amplification LPA® Refrigeration Energy Savings

Liquid Pressure Amplification, (LPA®) invented by HY-SAVE in 1984 is still the most efficient energy saving technology available for commercial refrigeration or air conditioning today. Refrigeration energy savings. The LPA® works by boosting liquid refrigerant through the refrigeration system. By increasing the liquid’s pressure, the associated saturation temperature is raised, while the liquid temperature remains the […]
