PROBLEM TO BE SOLVED: To provide a drain water injecting and dropping method to solve a problem of large decline in efficiency of an air conditioning cooling device when outside temperature becomes 33°C or 35°C. SOLUTION: Drain water generated from an indoor unit 6 during air-conditioning cooling operation is injected and dropped to a portion of an outdoor unit 1 having large heat generation amount so as to lower the heat generation amount. The portion to which water is injected and dropped is a high-temperature high-pressure portion 9 of an air exhaust radiator 3. Only the drain water is injected and dropped, and the amount of the injected and dropped water is approximately 3 cc per minute, beingh extremely small. This amount is increased/decreased depending on the humidity of the day, being supplied continuously. After wetting the high-temperature high-pressure portion 9, the injected and dropped water is applied to refrigerant gas piping immediately below the high-temperature high-pressure portion 9, and then, is discharged from a drain water final disposal port 5. Thus, cooling blowout temperature of the indoor unit 6 is lowered by 2-2.5°C, to improve energy saving effects. COPYRIGHT: (C)2010,JPO&INPIT |
