VARIABLE REFRIGERANT CHARGE CONTROL

摘要

An apparatus and method for adjusting refrigerant charge level are provided. The apparatus has a reservoir, a reservoir line, a reservoir valve, and one or more side valves. The reservoir line connects the reservoir and a liquid line, and has a connection to the liquid line. The liquid line connects an indoor heat exchanger and an outdoor heat exchanger. The reservoir valve is on the reservoir line. The one or more side valves are on the liquid line. In the method, an indicator of effectiveness of a refrigerant-using system is calculated. The indicator is compared to a target indicator of effectiveness. A refrigerant charge level is adjusted to reduce the difference between the indicator and the target indicator.
