What is the end result of the solenoid valve closing on a compressor with an internal unloader?

When a solenoid valve closes on a compressor equipped with an internal unloader, the end result is that the intake valve is held open. In this scenario, the solenoid valve controls the flow of refrigerant and stops it from entering the suction line when the compressor is not in operation. The internal unloader mechanism aids in relieving pressure within the compressor to prevent damage during startup. By holding the intake valve open, the internal unloader allows the compressor to continue operating without the risk of excessive pressure buildup, effectively managing the flow of refrigerant and maintaining system efficiency.

The action of the solenoid valve influences the compressor’s ability to regulate refrigerant flow adequately, and its closing prevents further refrigerant flow into the suction side. This interaction is vital in refrigeration systems to ensure that compressors function correctly under varying load conditions.
