General air-conditioner air-conditioning, when the indoor heat converter temperature is low, easily cause the fan condensation, convertible frequency air-conditioner particularly, if the control of the temperature of its pipe arrangement sensor is incorrect, be easy to cause fan to produce the condensation phenomenon, even can be blown out to outside space, cause electrical equipment or floor below the air-conditioning quality problems to occur.For example the indoor heat converter temperature is instantaneous low when the compression mechanism cold start-up, causes fan to produce condensation; Or compressor can cause the indoor fan condensation in when refrigeration during frequent start-stop, and dewdrop can constantly be grown up, and is blown out to the room through wind; Or than lower temperature the time, the continuous cooling operation, the pipe arrangement sensor temperature is lowly in the condensation temperature, and fan easily produces condensation, and dewdrop can constantly be grown up, and is blown out to the room through wind.
Summary of the invention
The purpose of this invention is to provide a kind of control method that prevents the convertible frequency air-conditioner of condensation, the method can effectively solve the problem of air-conditioning condensation, improves the security of self, and has stopped the phenomenon that air-conditioning blows out water.
The technical scheme that realizes the object of the invention is: the present invention includes following steps:
A, cooling activation, the scope interval of compressor operation hertz number is: 8Hz≤hertz number≤25Hz; If throttling arrangement is expansion valve, then the interval of the aperture scope of expansion valve is set as during cooling activation: 350pls≤expansion valve opening≤420pls;
B, when moving continuously, utilize the evaporator sensor temperature T 1 that evaporator sensor receives on the evaporator pipeline to come compressor operation hertz number is adjusted, specifically adjust as follows:
(1) when evaporator sensor temperature T 1＞the first design temperature Ts1, compressor operating hertz number is not subjected to this condensation condition criterion, and according to original method of operation operation, compressor operating hertz number is not less than 30 hertz;
(2) when the second design temperature Ts2＜evaporator sensor temperature T 1≤the first design temperature Ts1, compressor operation hertz number rises, and the scope that compressor operating hertz number rises is: 0.1 hertz≤hertz number≤30 hertz of rising;
(3) when the 3rd design temperature Ts3＜evaporator sensor temperature T 1≤the second design temperature Ts2, stable operation remains unchanged;
(4) when the 4th design temperature Ts4＜evaporator sensor temperature T 1≤the 3rd design temperature Ts3, compressor operating hertz number descends, and the scope that compressor operating hertz number descends is: 0.1 hertz≤hertz number≤30 hertz descend;
(5) when the 5th design temperature Ts5＜evaporator sensor temperature T 1≤the 4th design temperature Ts4, plasticator is with 1 hertz ~ 20 hertz operation hertz number operation; If after moving five to ten minutes, evaporator sensor temperature T 1≤the 4th design temperature Ts4, compressor is out of service;
(6) when evaporator sensor temperature T 1≤the 5th design temperature Ts5, compressor is out of service.
Above-mentioned the first design temperature Ts1 is 14 ℃, and the second design temperature Ts2 is 12 ℃, and the 3rd design temperature Ts3 is 10 ℃, and the 4th design temperature Ts4 is 6 ℃, and the 5th design temperature Ts5 is 5 ℃.
The present invention has positive effect: the sensor temperature that (1) the present invention passes by evaporimeter is come the operation of automatic control compressor, has higher automation effect; (2) result of use of the present invention is obvious, has well solved the problem of fan condensation; (3) the present invention is because solving the problem of condensation, so can improve the security of air-conditioning itself.
