In the present invention, unless otherwise clearly defined and limited, fisrt feature second feature " on " or D score can be that the first and second features directly contact, or the first and second features are by intermediary mediate contact.And, fisrt feature second feature " on ", " top " and " above " but fisrt feature directly over second feature or oblique upper, or only represent that fisrt feature level height is higher than second feature.Fisrt feature second feature " under ", " below " and " below " can be fisrt feature immediately below second feature or tiltedly below, or only represent that fisrt feature level height is less than second feature.
Air-conditioner is when freezing to indoor, by compressor, the refrigerant vapor compression of low pressure is become the vapor refrigerant of high pressure, then cold-producing medium becomes the liquid refrigerant of high pressure by outdoor heat exchanger, the liquid refrigerant of high pressure flows through restricting element and enters indoor heat exchanger, the air of indoor is absorbed heat, then flow back into compressor, complete indoor refrigeration.
The height of air-conditioner refrigeration depends primarily on the running frequency of compressor, compressor works and refrigeration can be made obviously to promote under higher running frequency, but the service life of compressor can be subject to certain impact, and the noise that the compressor worked under higher running frequency produces also can correspondingly increase.
Below in conjunction with Fig. 1 and Fig. 2, the control method of the air-conditioner according to the embodiment of the present invention is described in detail.
According to the control method of the air-conditioner of the embodiment of the present invention, as shown in Figure 1, can comprise the steps:
S1: during air-conditioner start refrigerating operaton, detect the running time of indoor temperature T1, outdoor temperature T4 and compressor, and indoor temperature T1 and the first decision content T1P, outdoor temperature T4 and first are judged that interval T4d-T4g compares.
S2: as T1 > T1P and T4d < T4 < T4g time, compressor runs with first frequency Frg, otherwise compressor runs with second frequency Fg, wherein first frequency Frg > second frequency Fg.That is, when air-conditioner start refrigerating operaton, must meet simultaneously indoor temperature T1 be greater than the first decision content T1P and outdoor temperature T4 is positioned at the first judgement interval time, compressor just runs with first frequency Frg, as long as indoor temperature T1 is less than the first decision content T1P and/or outdoor temperature T4 and exceeds the first judgement interval, compressor all runs with second frequency Fg.
In inventive embodiment, second frequency Fg is the running frequency of air-conditioner under common refrigerating state, to freeze object rapidly to realize air-conditioner start, first frequency Frg is higher than the frequency of air-conditioner under common refrigerating state (that is, second frequency Fg).
S3: when compressor to run with first frequency Frg and running time for U1 after, before the running time of compressor does not reach U2 total post-set time, when air-conditioner detect exit signal time, compressor runs with second frequency Fg.
Air-conditioner do not detect exit signal and reach total U2 post-set time the running time of compressor time, compressor runs with second frequency Fg.Thus the maximum duration that the compressor that known time U2 is setting works under first frequency Frg.
In other words, compressor is after running a period of time with first frequency Frg, compressor has two kinds from running with first frequency Frg to be transformed into the situation of second frequency Fg operation: a kind of situation is that the time U1 that compressor runs with first frequency Frg is greater than U2 post-set time, at this run duration, do not detect and exit signal; Although another kind of situation is that the time U1 that compressor runs with first frequency Frg does not exceed U2 post-set time, detects and exit signal.
According to the control method of embodiment of the present invention air-conditioner, indoor temperature T1 and the first decision content T1P, outdoor temperature T4 and first are judged that interval T4d-T4g compares, meet T1 > T1P and T4d < T4 < T4g time, compressor runs with first frequency Frg, thus reaches the object making room fast cooling.
In addition, when compressor with the time U1 that first frequency Frg runs be greater than post-set time U2 or detect exit signal time, compressor machine runs with second frequency Fg.Ensure that compressor can not work under long-time high-frequency state thus, improve the service life of compressor.

Condition a: indoor temperature T1 is less than the second decision content T1t;
Condition b: outdoor temperature T4 exceeds the interval T4d-T4g of the first judgement;
When exiting signal for combination, then when meeting one of them condition, compressor runs with second frequency Fg, wherein the second decision content T1t≤the first decision content T1P, and namely the second decision content T1t is not more than the first decision content T1P.
That is, be now divided into three kinds of situations, a kind of situation is the signal that exits of air-conditioner setting is that indoor temperature T1 is less than the second decision content T1t, time then in this case, when only detecting that indoor temperature T1 is less than the second decision content T1t, namely satisfy condition a time, compressor runs with second frequency Fg.The second situation is the signal that exits of air-conditioner setting is that outdoor temperature T4 exceeds the interval T4d-T4g of the first judgement, then in that case, only detect that outdoor temperature T4 exceeds the interval T4d-T4g of the first judgement, namely satisfy condition b time, compressor runs with second frequency Fg.
The third situation is the signal that exits of air-conditioner setting is the combination that indoor temperature T1 is less than the second decision content T1t and outdoor temperature T4 and exceeds the interval T4d-T4g of the first judgement, then in that case, as long as detect that indoor temperature T1 is less than the second decision content T1t or outdoor temperature T4 when exceeding the first interval T4d-T4g of judgement, compressor runs with second frequency Fg, that is, in that case, exit the combination that signal is condition a and condition b, in the process that compressor runs with first frequency Frg, one of them as long as satisfy condition in a and condition b, compressor runs with second frequency Fg.
Alternatively, the span of the difference between the second decision content T1t and the first decision content T1P is 1 DEG C ~ 2 DEG C.
