Description
Technical field
The present invention relates to air-conditioning technical field; Be specially the energy-saving control system of air-conditioning temperature-constant operation, this method can be according to the indoor and outdoor variation of ambient temperature, through compressor or terminal work and the stand-by time of central air conditioner in cold or the next working cycle of heat Calculation prediction air-conditioning; Thereby make the temperature in the room constant relatively; Reach the purpose of the working time that reduces compressor, realized the constant temperature energy-saving of air-conditioned room, and be fit to the constant temperature energy-saving control of various civilian air-conditionings.
Background technology
Air-conditioning has two kinds of working methods at present, and a kind of is exactly fixed frequency air conditioner, and another kind is a convertible frequency air-conditioner.During fixed frequency air conditioner work, be after configuring required temperature value, reach the purpose of adjusting room temperature through the ON/OFF of control compressor of air conditioner; And convertible frequency air-conditioner when work, configure the room temperature that needs as people after, it is to arrive thermostatic control temperature purpose through the frequency of operation of regulating compressor.After convertible frequency air-conditioner works long hours, can improve about 35% energy-saving effect than common fixed frequency air conditioner.
As everyone knows; The environment temperature of human body the most comfortable is 27～27.5 ℃; What the adjustment of common fixed frequency air conditioner was leaned on is that the temperature value that temperature sensor detects is judged, because in order to guarantee that air-conditioning can adapt to the not use of chummery, generally all is set at its work controlling models: under refrigeration mode in air-conditioning; Compressor operating is desired temperature+1 ℃ constantly, and it quits work constantly and to be desired temperature-2 ℃.This control model makes air-conditioning the time leave sizable temperature space in work, and room temperature has bigger fluctuation, and the people can obviously feel variation of temperature in the room; Therefore for to overcome the discomfort that this temperature difference is brought, people are set to fixed frequency air conditioner below 26 ℃ usually, and wear an overcoat; Can feel pleasant like this, but this situation continues oversize easy again " air conditioner disease ", and temperature is low more; The loss of air-conditioning cold flow is just big more, otherwise, under heating mode; Thermal loss is also big more, and the consumption of electric energy is bigger, makes the increase that use cost is unnecessary.
Convertible frequency air-conditioner is controlled refrigerating capacity through the frequency of operation of regulating compressor, and its work controlling models is set at: control to environment temperature to be less than about to be provided with under the temperature and work, compressor is not shut down basically; Its comfort level is relatively good, can be set to 27 ℃ to setting value, and the energy-saving effect that works long hours is apparent in view, and warp test convertible frequency air-conditioner fixed frequency air conditioner on year-on-year basis has the energy-saving effect about 35%.But owing to what frequency converter adopted is the high voltage and high power device, and its working temperature is higher, and reliability is relatively poor, and cost is higher, and maintenance cost is also quite big, and itself yet has the energy consumption about 15%, and use feeling is still undesirable when sleep.
