A METHOD AND A SYSTEM FOR ESTIMATING LOSS OF REFRIGERANT CHARGE IN AN RVCS SYSTEM

摘要

A level sensor is configured to provide a receiver level indicating an amount of the refrigerant present in the receiver and a level model provides a heat rejecting heat exchanger estimate indicating an amount of the refrigerant present in the heat rejecting heat exchanger based on a temperature of the refrigerant. From the sensor and the model, a loss of refrigerant from the RVCS system is estimated.
