Résumé

NREL measured the energy performance of the refrigerant pump system technology in a supermarket hydro-fluorocarbon system operation. The system solves the problems of previous attempts to use a pump to move liquid refrigerant in DX systems. It uses a patented method to provide sufficient net positive suction head (NPSH) to the liquid pump at all times. The refrigerant pump system operated continuously without failure under all weather and refrigeration demand conditions during the testing period. The system was turned on and off to measure performance under similar conditions. Conventional system operation resumed with no further action than switching the unit off.
