Abstract
A method for operating a transcritical refrigeration system wherein a more optimal compressor parameter such as output pressure, pressure ratio or power consumption is determined using heat exchanger refrigerant inflow temperatures and/or outflow temperatures and also the enthalpy change across the evaporator and adjusting the compressor operation or refrigerant fluid working mass accordingly.
