A determination means 46 compares the measured time intervals with the limit value of the memory means. When a measured value exceeds the limit value, it is determined that the crystallization is progressing. A control means 48 is connected to a valve V4. When the control means 48 receives a crystallization signal from the determination means, the valve V4 is opened. Therefore, when the crystallization is determined, the valve V4 is opened so that the refrigerant in a refrigerant tank 18 may flow in a diluted solution tank 21 which makes it possible to drop the concentration of the solution to a large extent and solve the crystaltization problem.
