Embodiment 3

[0040] Embodiment three: see image 3 .

[0041] image 3 The curves S1 and S2 in the figure are respectively the first preset frequency curve and the second preset frequency curve corresponding to each specific temperature difference ΔTs. It can be seen from the figure that corresponding to each temperature difference ΔTs on the abscissa, the points on the first preset frequency curve S1 are larger than the points on the second preset frequency curve S2, and the difference is 15 Hz. That is to say, the difference between the first preset frequency and the second preset frequency is a fixed value, both of which increase with the increase of the temperature difference ΔTs. certainly, image 3 It is not intended to limit the relationship between the phenomenon of the first preset frequency and the second preset frequency increasing as the temperature difference ΔTs increases. image 3 The first preset frequency curve S1 and the second preset frequency curve S2 shown are two ...

Embodiment 4

[0043] Embodiment four: see Figure 4 .

[0044] Figure 4 The curves S1 and S2 in the figure are also the first preset frequency curve and the second preset frequency curve corresponding to each specific temperature difference ΔTs, respectively. Depend on Figure 4 It can be seen from the curve that in the fourth embodiment, corresponding to each temperature difference ΔTs, the first preset frequency and the second preset frequency are in a proportional relationship. The relationship between the two straight lines S1 and S2 in the figure can be expressed as S2= 0.5*S1. The proportionality coefficient may be between 0 and 1, and there is no limitation here, as long as the first preset frequency is greater than the second preset frequency and has a proportional relationship with the second preset frequency.

Embodiment 5

[0045] Embodiment five: see Figure 5 .

[0046] Curve S1 and curve S2 in the figure are also the first preset frequency curve and the second preset frequency curve corresponding to each specific temperature difference ΔTs, respectively. In this embodiment, the curve S2 representing the second preset frequency is a straight line parallel to the abscissa with a slope of zero, that is to say, the second preset frequency here is a fixed frequency value, such as the 20Hz. The first preset frequency curve S1 increases as the temperature difference ΔTs increases, and the greater the temperature difference ΔTs, the greater the first preset frequency.

[0047] The air conditioner control method provided by the present invention can calculate the temperature difference ΔTs between the real-time indoor temperature Tn and the indoor target temperature Tm by detecting the real-time outdoor temperature Tw and the real-time indoor temperature Tn according to the needs of users. As a resu...

Abstract

The invention belongs to the field of air conditioner control, and particularly relates to an energy-saving control method of an air conditioner. By using the control method of the air conditioner provided by the invention, according to the requirement of a user, outdoor real-time temperature Tw and indoor real-time temperature Tn are detected, the temperature difference delta Ts between the indoor real-time temperature Tn and the indoor target temperature Tm is calculated; according to a comparison result of the outdoor real-time temperature Tw and a preset outdoor temperature threshold Ty, the air conditioner is controlled to operate under a first preset frequency or a second preset frequency corresponding to the temperature difference delta Ts. The operation frequency of the air conditioner is adjusted anytime, the operation temperature of the air conditioner is controlled in the optimum comfortable state, the refrigeration and heating requirements of the user can be met, the user experience is improved, the power consumption of the air conditioner is reduced, and energy-saving and environment-protecting effects are realized.

Description

technical field [0001] The invention belongs to the field of air conditioner control, in particular to an energy-saving control method for an air conditioner. Background technique [0002] Air conditioners are criticized by the majority of users as a large power consumer in household appliances. However, with the improvement of energy efficiency, inverters are more and more widely used in the market, and they have indeed played a lot in reducing energy consumption for air conditioners. . However, in the usual use of the air conditioner, the temperature control is realized by setting the indoor target temperature. Often after the temperature is set, there will be no more adjustments, and the air conditioner will always follow the set temperature. Set the temperature as the target operation. [0003] Take the air conditioner cooling in summer as an example, in order to achieve the purpose of rapid cooling, the user usually sets a lower temperature at the beginning of the air...
