Problems solved by technology

[0004] In addition, the control of the room temperature by the air conditioner is mainly adjusted according to the temperature felt by the return air temperature sensor. Since the return air temperature sensor is often affected by the installation location, radiation, and response time, the temperature felt by the return air temperature sensor cannot truly reflect the user’s temperature. The temperature of the normal activities and living areas leads to the inaccurate temperature control of the air conditioner and large temperature fluctuations, which affects the user's comfort and sometimes even causes the air conditioner to run in a non-energy-saving manner.

Embodiment 1

[0039] like figure 1 , 2 As shown, the present invention discloses a control method for the operation of air-conditioning equipment, and the control method includes the following steps,

[0040] Step 1, when the indoor unit 2 receives the power-on signal from the remote controller 9, the air-conditioning equipment runs. When the air-conditioning equipment is running, detect the return air temperature T1 of the indoor unit 2 of the air-conditioning equipment; in order to improve the effective working time of the present invention, in this embodiment, when the air-conditioning equipment is running, it is judged whether the current operating mode of the air-conditioning equipment is refrigeration , heating, and dehumidification; if yes, detect the return air temperature of the indoor unit 2 of the air-conditioning equipment, and if no, return to the judgment step.

[0041] Step 2, obtaining at least one parameter among the pipe temperature T2 of the indoor unit 2 of the air con...

Embodiment 2

[0056] This embodiment is basically the same as Embodiment 1, the difference being that in this embodiment, two parameters are used to compensate the return air temperature.

[0057] Specifically, use the indoor unit 2 pipe temperature of the air-conditioning equipment to compensate the return air temperature: determine the temperature range of the pipe temperature, and obtain the corresponding first temperature compensation value according to the temperature range, and the return air temperature after compensation is the value before this compensation. The sum of the return air temperature and the first temperature compensation value; use the motor speed of indoor unit 2 to compensate the return air temperature: determine the speed range of the speed, and obtain the corresponding second temperature compensation value according to the speed range, and return air after compensation The temperature is the sum of the return air temperature before this compensation and the second t...

Embodiment 3

[0060] This embodiment is basically the same as Embodiment 1, the difference being that in this embodiment, two parameters are used to compensate the return air temperature.

[0061] Specifically, use the indoor unit 2 pipe temperature of the air-conditioning equipment to compensate the return air temperature: determine the temperature range of the pipe temperature, and obtain the corresponding first temperature compensation value according to the temperature range, and the return air temperature after compensation is the value before this compensation. The sum of the return air temperature and the first temperature compensation value; use the distance between the indoor unit 2 and the opposite wall to compensate the return air temperature: judge the distance interval, and obtain the corresponding third temperature compensation value according to the distance interval, after compensation The return air temperature is the sum of the return air temperature before this compensatio...

Abstract

The invention discloses an air conditioning equipment operation control method and system and an air conditioner. The control method comprises the following steps: detecting the return air temperature of the indoor unit of air conditioning equipment when the air conditioning equipment operates; acquiring at least one of the following parameters such as the tube temperature and the motor speed of the indoor unit of the air conditioning equipment as well as the distance between the indoor unit and the wall body on the opposite side; utilizing the at least one parameter for compensating the return air temperature so as to acquire the compensated return air temperature; and controlling the air conditioning equipment to operate based on the compensated return air temperature. The control system comprises a controller, a first temperature sensor, and at least one of a second temperature sensor, a rotating speed detection device and an infrared sensor; and the air conditioner comprises the air conditioning equipment operation control system. According to the air conditioning equipment operation control method and system and the air conditioner, through the return air temperature compensation, the temperature sensed by a return air temperature sensor is closer to that of a user's normal activity or living area, so that precise temperature control is realized, and the usage comfort level of the user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically, the invention relates to a method and system for controlling the operation of air conditioning equipment, and an air conditioner. Background technique [0002] For general room air conditioners, a return air temperature sensor is often arranged on the air return port of the indoor unit of the air conditioner to detect the temperature of the return air port of the indoor unit. [0003] However, since the indoor unit of the air conditioner is generally installed at a height of more than 2 meters, the height of the return air temperature sensor is more than 2 meters from the ground, and the normal activities and living areas of the user's room are generally below 2 meters. Due to the height difference, the temperature field in the room is non-uniform, and the temperature felt by the return air temperature sensor is quite different from the temperature in the user's no...
