Abstract
A refrigeration apparatus includes a compressor, a heat source-side heat exchanger, a receiver, a utilization-side heat exchange, a receiver degassing pipe interconnecting an upper portion of the receiver and a suction side of the compressor, and a receiver liquid level detection pipe connected to the receiver. The receiver liquid level detection pipe detects whether or not liquid level in the receiver has reached a predetermined position on a lower side of a position where the receiver degassing pipe is connected. The receiver liquid level detection pipe merges with the receiver degassing pipe via a capillary tube. The receiver degassing pipe has a refrigerant heater to heat refrigerant flowing through the receiver degassing pipe. Whether or not the liquid level in the receiver has reached the predetermined position is detected using a temperature of refrigerant flowing though the receiver degassing pipe.
