Abstract

An HVACSR system is disclosed that utilizes energy-efficient valving. The valving controls the flow of refrigerant and may be adapted for evaporator or condenser applications, on both AC systems and heat pumps (as well as chillers and other refrigeration systems). The valving (236) may provide simultaneous and individualized control of flow through individual coils or groups of coils (226) for improved control of evaporation, condensation, defrosting and so forth. In some configurations a common sensor (132) may be shared between individual coils or groups of coils and may provide sensed parameters to control circuitry for controlling the valving. Other configurations may include bypass valving (238) to direct fluid around the flow control valving. In yet other configurations, a valve (260) may be used to bypass tapped vapor around a heat exchanger (80) functioning as an evaporator.
