Description

Control method, control system and the air-conditioner of air-conditioner

Technical field

The present invention relates to air-conditioner technical field, in particular to control system and a kind of air-conditioner of a kind of control method of air-conditioner, a kind of air-conditioner.

Background technology

Along with the raising of people's living standard, the popularity rate of air-conditioner is more and more higher.Because air-conditioner is to drive by electric energy the equipment that carries out cooling and warming, if therefore there is more air-conditioner to use simultaneously, can cause need for electricity to be increased sharply, even can exceed the actual electric power deliverability of electrical network, cause the overload operation of electrical network, force power supply administration's power cuts to limit consumption of having to.

In order to alleviate the excessive impact causing electrical network of peak times of power consumption air-conditioner power consumption, country's relevant policies require summer air-conditioning design temperature more than 26 ℃, winter heating Temperature Setting is below 20 ℃, to avoid user to set lower temperature in summer, set in the winter time the power consumption that increases air-conditioner compared with high temperature, but due to the requirement difference of different use crowds to temperature, if according to the design temperature of unified standard setting air-conditioner, can reduce user's comfort.

In addition, the occasion that cannot reach design temperature for some, air-conditioner, still with maximum load operation, can produce higher running current and operate power, and electrical network is caused to larger impact.

Therefore, how, under guaranteeing that user has compared with the prerequisite of high degree of comfort, reduce the power consumption of air-conditioner, avoid air-conditioner power consumption excessive and electrical network is impacted and becomes technical problem urgently to be resolved hurrily.

A lot of details are set forth in the following description so that fully understand the present invention; but; the present invention can also adopt other to be different from other modes described here and implement, and therefore, protection scope of the present invention is not subject to the restriction of following public specific embodiment.

Fig. 1 shows the schematic flow diagram of the control method of air-conditioner according to an embodiment of the invention.

As shown in Figure 1, the control method of air-conditioner according to an embodiment of the invention, comprising: step 102, and the target of the air-conditioner that Real-time Obtaining user sets regulates temperature; Step 104, regulates the residing temperature range of temperature according to described target, and the realistic objective of adjusting described air-conditioner regulates temperature, regulates temperature to regulate indoor temperature for described air-conditioner according to described realistic objective.

Regulate the residing temperature range of temperature by the target of setting according to user, the realistic objective of adjusting air-conditioner regulates temperature, the target that air-conditioner can be set user in the reasonable scope regulates temperature to carry out suitable adjustment, for example, under refrigeration mode, if user has set lower target and has regulated temperature, the realistic objective that can suitably heighten air-conditioner regulates temperature, under heating mode, if user has set higher target and has regulated temperature, the realistic objective that can suitably turn down air-conditioner regulates temperature, to reduce the operate power of air-conditioner, and then the power consumption of reduction air-conditioner, reduce the impact to electrical network.
