Abstract:
A liquid level detection device detects the level of liquid refrigerant (15b) in a refrigeration cycle device in which refrigerant (15) circulates through a compressor (1), a condenser (4), an expansion device (6), and an evaporator (7) in that order. The refrigeration cycle device is provided with a liquid storage container (30) which includes an upper surface and a lower surface, and which stores the liquid refrigerant. The liquid level detection device is provided with: a monitor container (10) for monitoring the liquid level inside the liquid storage container; a first communication pipe (11) which is connected between the upper surface of the liquid storage container and an upper part of the monitor container; a second communication pipe (12) which is connected between the lower surface of the liquid storage container and a lower part of the monitor container; and detectors (13, 14) which detect the liquid level inside the monitor container.
