Abstract

A temperature control system includes a compressor, a condenser, an evaporator, and an accumulator. A liquid level sensor is associated with the accumulator tank generates a signal indicative of the level of the liquid heat transfer fluid inside the accumulator. A valve is in fluid communication with the condenser, the compressor, and the evaporator and is operable in a first position and a second position. The first position directs the heat transfer fluid from the compressor to the condenser, and the second position directs the heat transfer fluid from the compressor to the evaporator without passing through the first heat exchanger. A controller is in electrical communication with the liquid level sensor and the valve and is operable to receive the signal and move the valve from the first position to the second position based on the signal.
