Title:
A refrigerating cycle device and a surface detection sensor
Document Type and Number:
Japanese Patent JP6180652
Kind Code:
B2
Abstract:
Provided is a refrigeration cycle apparatus including: a refrigerant circuit formed by connecting, by a refrigerant pipe, a compressor, a condenser, an expansion device, an evaporator and a liquid reservoir; a liquid level detection sensor including a plurality of heat generating units and a plurality of temperature detection units, the heat generating units being paired with the temperature detection units, and provided in the liquid reservoir, the liquid level detection sensor being configured to detect a liquid level of a refrigerant accumulated in the liquid reservoir, based on a temperature of each of the heat generating units, in which the liquid reservoir includes a container for accumulating the refrigerant, an inlet pipe connected to the refrigerant circuit and configured to allow a portion of the refrigerant flowing out of the container to flow into the container, and in which in the container, a shielding portion is provided between an discharge outlet for the refrigerant of the inlet pipe and the liquid level detection sensor, to prevent the portion of the refrigerant flowing out of the discharge outlet from directly coming into contact with the liquid level detection sensor.
