Problems solved by technology

[0007] The purpose of the present invention is to provide a control method for an air conditioner. While solving the problem of uncomfortable cooling caused by the cold air blown out by the existing inverter air conditioner, it also takes into account the comfort of the indoor temperature adjustment of the air conditioner and the low power consumption and energy saving of the air conditioner. And can be flexibly controlled according to the temperature of the human body

Embodiment Construction

[0034] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] How to improve the temperature adjustment comfort of the air conditioner and reduce the power consumption of the air conditioner has always been a hot spot and focus in the research of the air conditioner industry. Most of the existing air conditioners are inverter air conditioners. The prior art mostly focuses on the processing of the control algorithm of the air conditioner in terms of improving the comfort and reducing power consumption of the inverter air conditioner, for example, using PID algorithm and fuzzy control algorithm. Regardless of the control algorithm, when the current indoor temperature is used as a parameter, the indoor temperature detected by the indoor temperature sensor installed on the air conditioner is directly used as the current indoor temperature, and then the indoor tempera...

Abstract

The invention discloses an air conditioner control method which comprises the following steps: when an air conditioner gets into indoor temperature PID control, acquiring a current indoor temperature as a first indoor temperature, taking the difference between the first indoor temperature and a set compensation temperature as a second indoor temperature, calculating the temperature difference between the second indoor temperature and a current indoor target temperature, and performing indoor temperature PID calculation according to the temperature difference to obtain a first target frequency; comparing the second indoor temperature with a set comfortable temperature, and determining to execute indoor temperature PID control or fuzzy control according to a comparison result; and detecting a human body temperature during the process of the indoor temperature PID control or the fuzzy control, and increasing the current indoor target temperature when the human body temperature is abnormal. Through the application of the air conditioner control method, the problem of uncomfortable refrigeration caused by cold air from a conventional inverter air conditioner is solved, and meanwhile both the comfort of indoor temperature regulation of the air conditioner and the low power consumption and energy conservation properties of the air conditioner are taken into account.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioner control method. Background technique [0002] In the hot summer, many people cannot do without the air conditioner all day and all night. However, blowing air conditioners for a long time has many harms to the human body, and it is easy to get air conditioner diseases. [0003] Although the existing inverter air conditioner can control the operating frequency of the compressor, its control basis is only the indoor temperature and the set indoor target temperature, and will not change the air outlet temperature of the air conditioner. And in order to reach fast refrigeration, the outlet air temperature of existing air conditioner will be far lower than setting temperature, and the air outlet air temperature of air conditioner is low, and the wind that blows out is cold wind. When the cold wind blows on the human body, it feels extremely un...
