Description
Technical field
The present invention relates to a kind of air conditioning control method, particularly a kind of control method that improves comfortability of frequency conversion air conditioner wind-discharging temperature.
Background technology
General, according to the requiring air-conditioning to carry out kind of refrigeration cycle or heat circulation of user, when the indoor heat converter of air-conditioning is to heat circulation during as condenser; And when the indoor heat converter of air-conditioning be kind of refrigeration cycle during as evaporimeter.Referring to accompanying drawing 2, be the refrigerating/heating circulation sketch of general air-conditioning.
Its running that heats circulation is: at first at compressor 1 compression refrigerant gas, and the refrigerant after the compression is through cross valve 2 commutations, be admitted in the indoor heat converter 3, blower fan 6 runnings of indoor heat converter at this moment, room air becomes warm braw through over-heat-exchanger 3 heat exchangers.The refrigerant of indoor heat converter 3 flow in the outdoor heat converter 5 by throttling arrangement 4, evaporate at outdoor heat converter 5, and the blower fan 7 by outdoor heat converter is to outdoor discharge cold wind.
The running of its kind of refrigeration cycle is: at first at 1 li compression refrigerant of compressor, and the refrigerant after the compression is through cross valve 2 commutations, be admitted in the outdoor heat converter 5, blower fan 7 runnings of outdoor heat converter at this moment, 5 heat exchange become warm braw to outdoor air through outdoor heat converter.The refrigerant of outdoor heat converter 5 flow in the indoor heat converter 3 by throttling arrangement 4, evaporate at indoor heat converter 3, and the blower fan 6 by indoor heat converter is to indoor discharge cold wind.
Below, the action in the frequency-variable air-conditioner start-up course (is example with the refrigeration) is in the past described.
During starting of air conditioner, compressor 1 operation, draw refrigerant in the indoor heat converter from the refrigerant system of poised state, reduce the refrigerant pressure in the indoor heat converter, the high pressure refrigerant gas inlet chamber outer heat-exchanger that compressed machine pressurization is discharged, improve the refrigerant pressure of outdoor heat converter, while throttling arrangement 4, be electric expansion valve, open certain bore, the refrigerant of high and low pressure side is carried out throttling, after this process continues the regular hour, on high-tension side pressure has reached the condensing pressure under the outdoor temperature, and further compressor air-discharging will be to outdoor heat extraction, and gases at high pressure are condensed into highly pressurised liquid; Highly pressurised liquid becomes low pressure liquid through the electric expansion valve throttling simultaneously, and this low pressure liquid evaporates in indoor heat converter, the heat of beginning absorption chamber inboard.So we can see, in the process of compressor start, the heat absorption of indoor is considerably less when just bringing into operation, the main acting of compressor all is used to make original pressure balanced refrigerant, become the high-pressure side and can carry out condensation, condensed fluid can evaporate through throttling, at this moment just to reducing indoor temperature contribution is arranged.
When adopting convertible frequency air-conditioner, the external environment during starting of air conditioner is the most abominable, i.e. the temperature difference maximum of indoor temperature and user's design temperature, and the while outdoor temperature is higher.Because load is big, convertible frequency air-conditioner often adopts the mode that increases frequency to increase the ability of refrigeration, and still load is big, and the frequency height has directly caused the running current increase.In the prior art, the impact that causes for fear of big electric current, and vibrations that cause and noise, often adopt slow gradient to increase the method for air-conditioning frequency, make the starting current of air-conditioning can not produce big impact, reduce the capacity of compressor like this at the starting of air conditioner initial stage, further caused starting of air conditioner to reach the time lengthening of normal operation again.
From prior art as can be seen, the acting of the compressor when starting of air conditioner is mainly used in the evaporative condenser environment that the interior environment that makes the refrigerant system becomes the height pressure reduction of suitable cooling, and the actual temperature disparity in user's design temperature and the room at this time, the user feels under the weather, behind the operation of air conditioner certain hour, after system's height pressure reduction formed, the refrigerant liquid process throttling step-down through condensation just began to reducing room temperature contribution is arranged in the indoor set evaporation.In addition, we can also see, adopt frequency-variable air-conditioner, for fear of the impact of crossing great start-up current, the gradient that frequency-changeable compressor adopts increases the method for air-conditioning frequency, reduce the capacity of compressor at the starting of air conditioner initial stage, further caused starting of air conditioner to reach the time lengthening of normal operation again.The user after starting air-conditioning, must wait for that convertible frequency air-conditioner is finished above pressure balance after, reach the electric machine frequency increase after, just can feel the reduction of air-conditioning to room air.
