Embodiment Construction

[0047] The core of the present invention is to provide a control method of an air conditioner, which can improve the versatility of the outdoor unit. Another core of the present invention is to provide an air conditioner using the control method.

[0048] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] like figure 1 As shown, the air conditioner control method provided by the embodiment of the present invention includes the following steps:

[0050] S0. After the unit is powered on, the outdoor unit will perform the initialization process after receiving the start-up command and operation mode. The initialization process is specifically: pre-set the initial target frequency of the variable frequency compressor, and after the variable frequency The speed is increased ...

Abstract

The invention discloses a control method for an air conditioner. The control method comprises the following steps: S1, presetting a target pressure P0 and the superheat degree T0 of the outlet of a target evaporator; S2, acquiring an actual pressure P1 and the superheat degree T1 of the outlet of an actual evaporator; S3, calculating the difference value delta P between the actual pressure P1 and the target pressure P0, and the difference value delta T between the superheat T1 of the outlet of the actual evaporator and the superheat degree T0 of the outlet of the target evaporator; S4, adjusting the frequency of a frequency-variable compressor according to the difference value delta P between the actual pressure P1 and the target pressure P0 to maintain the actual pressure P1 within the range of the target pressure P0, and adjusting the open degree of an electronic expansion valve according to the difference value delta T between the superheat T1 of the outlet of the actual evaporator and the superheat degree T0 of the outlet of the target evaporator to maintain the superheat degree T1 of the outlet of the actual evaporator within the range of the superheat degree T0 of the outlet of the target evaporator; S5, repeating the steps of S2 to S4 according to a preset cycle. The invention also discloses the air conditioner applying the control method. By the control method, the universality of an outdoor unit is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method. The present invention also relates to an air conditioner applying the above control method. Background technique [0002] The air conditioner absorbs the heat of the indoor air or releases heat to the room through the evaporation or condensation of the refrigerant, so as to achieve the purpose of adjusting the indoor temperature. With the continuous development of science and technology, the performance of air conditioners has received more and more attention. [0003] An air conditioner generally includes two parts: an outdoor unit and an indoor unit. The two parts need to be matched according to parameters such as fan power, compressor power, and heat exchange heat transfer capacity during installation. The structure of the two is also the same as the outdoor unit and the indoor unit Factors to consider when matching machines. In t...
