報がある。2. Description of the Related Art Conventionally, when a solution is mixed with a refrigerant, the evaporation capacity of the evaporator is reduced and the concentration on the solution side is increased, and excess refrigerant accumulates in the refrigerant tank, which overflows into the absorber, Are being purified or crystals are prevented. However, if only overflow occurs, refining of the refrigerant takes time, and in reality, the refrigerant is manually transferred to the absorber by the refrigerant pump. Further, it is not possible to know whether the specific gravity of the refrigerant is large unless the refrigerant is sampled and measured. As prior art of this type, there is JP-A-56-146965.

備えてある電磁弁を開にし、冷媒を移送する。In order to detect a change in the specific gravity of the refrigerant, a float switch is provided in the refrigerant tank, and the float switch floats when the specific gravity is 1.1 or more and is 1.1 or less, for example. In the case of, it has the function of sinking and turning the switch on and off. In conjunction with the detection of the specific gravity of the float switch refrigerant, the solenoid valve provided in the refrigerant transfer pipe to the absorber is opened to transfer the refrigerant.

る。The amount of the mixed solution in the refrigerant can be detected by the specific gravity. (Specific gravity of water 1.0, specific gravity of solution 1.6 ~
1.8). When the specific gravity of the refrigerant becomes about 1.1 due to the mixture of the solution, the capacity of the evaporator is significantly reduced, and refining of the refrigerant is necessary. If float weight (built-in reed switch) of float switch is float weight / float volume = 1.1, float floats with specific gravity of 1.1 or more and switch turns on.
