摘要： An air-conditioner and the refrigerant charging method of the air-conditioner are disclosed. When a refrigerant amount determining mode is requested to be performed, whether or not the refrigerant amount in the air-conditioner is proper is automatically determined and a shortage amount of refrigerant can be charged. Thus, a user can easily check whether or not the refrigerant charged in the air-conditioner is sufficient or insufficient, and if the refrigerant is not sufficient, the user can automatically charge the refrigerant without having to entirely remove the refrigerant from the air-conditioner, thus increasing the user convenience and reducing time and costs.

摘要： Provided is a temperature-adjusting fluid supply apparatus that causes a fluid for temperature adjustment to be circulated between a heat exchanger that transfers heat supplied from a refrigerant to the fluid, and an object to be adjusted for temperature that uses the heat of the fluid, the temperature-adjusting fluid supply apparatus being able to prevent the fluid from freezing. A temperature-adjusting fluid supply apparatus (100) is provided with a heat exchanger (20) that transfers heat supplied from a refrigerant to a fluid for temperature adjustment, a supply tube (32) through which the fluid flows from the heat exchanger toward an object to be adjusted for temperature, a return tube (42) through which the fluid returning from the object to be adjusted for temperature flows, a flow rate adjustable pump (50), a flow sensor (60), a flow switch (70), a temperature sensor (80), and a control part (90). The flow switch, in comparison with the flow sensor, is able to detect flow rate changes with coarser precision, and is less affected in detection accuracy by viscosity changes in the fluid. On the basis of the temperature of the fluid detected by the temperature sensor, the control part switches between pump control based on the detection results of the flow sensor and pump control based on the detection results of the flow switch.
