Embodiment 1

[0023] Embodiment 1 of the present invention provides a method for controlling the speed of an air conditioner fan, figure 1 It is a flow chart of the steps of the air-conditioning fan speed control method in Embodiment 1 of the present invention, as figure 1 As shown, the control method includes the following steps S101 to S104.

[0024] Step S101: Detect the return air temperature and the supply air temperature of the air conditioner.

[0025] Specifically, a temperature-sensing package is installed at the return air outlet of the air conditioner, and the return air temperature of the air conditioner is detected by obtaining the temperature of the temperature-sensing package at the return air outlet. Temperature to detect the supply air temperature of the air conditioner.

[0026] For the case where multiple temperature-sensing packages are set at the return air outlet, the return air temperature is the average temperature of all the temperature-sensing packages at the ret...

Embodiment 2

[0036] Embodiment 2 of the present invention provides a preferred air-conditioning fan speed control method on the basis of the above-mentioned embodiment 1. For related descriptions, please refer to the above-mentioned embodiment 1. figure 2 It is a flow chart of the steps of the air-conditioning fan speed control method in Embodiment 2 of the present invention. In this embodiment, the return air temperature difference is set on the basis of the initial set value and adjusted in real time according to the operating parameters of the air conditioner. Specifically, as figure 2 As shown, the control method includes the following steps S201 to S207.

[0037] Step S201: Detect the return air temperature and supply air temperature of the air conditioner.

[0038] Step S202: Calculate the difference between the return air temperature and the supply air temperature to obtain the real-time return air temperature difference.

[0039] Step S203: Detect whether the predetermined compo...

Embodiment 3

[0055] Embodiment 3 of the present invention provides a preferred air-conditioning fan speed control method on the basis of Embodiment 1 and Embodiment 2 above. For related descriptions, please refer to Embodiment 1 and Embodiment 2 above. image 3 It is a flow chart of the steps of the air-conditioning fan speed control method in Embodiment 3 of the present invention, as image 3 As shown, when the air conditioner is in cooling mode, the control method includes the following steps.

[0056] This embodiment provides a method for controlling the fan speed by automatically adjusting the set value of return air temperature difference for fan coil units and similar end-type air conditioners. In this embodiment, after the unit is turned on, the fan will After a minute (a ≥ 0) at a speed of operation, the return air temperature and supply air temperature of the air conditioner are measured by the return and supply air temperature sensing devices, and the air conditioner unit determi...

Abstract

The invention discloses an air conditioner draught fan rotating speed control method and an air conditioner system. The air conditioner draught fan rotating speed control method comprises the steps that the air return temperature and the air feed temperature of an air conditioner are detected; the difference value of the air return temperature and the air feed temperature is calculated so as to obtain the real-time air return and feed temperature difference; the set air return and feed temperature difference is obtained, wherein the set air return and feed temperature difference is the set difference value of the air return temperature and the air feed temperature; and according to the difference value of the real-time air return and feed temperature difference and the set air return and feed temperature difference, the rotating speed of an air conditioner draught fan is adjusted. Through the air conditioner draught fan rotating speed control method and the air conditioner system, therotating speed of the draught fan can be adjusted according to the difference value of the real-time air return and feed temperature difference and the set air return and feed temperature difference,change of the room load is rapidly responded, and the proper refrigerating quantity and heating quantity are output in time.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and more specifically, to a method for controlling the speed of an air conditioner fan and an air conditioner system. Background technique [0002] Air volume is an important factor affecting the overall performance of air-conditioning equipment. It is more common in air-conditioning equipment to change the air volume by adjusting the fan speed. At present, the air conditioning system can adjust the fan speed according to the range of the difference between the detected ambient temperature and the set temperature, or according to the preset temperature range to which the difference between the indoor ambient temperature and the outlet air temperature belongs. Several gears are used to achieve the purpose of air volume adjustment, but this adjustment method is not very flexible. When the load in the room changes rapidly, the cooling capacity or heat output of the air conditioner w...
