Embodiment

[0039] see figure 1 , figure 1 It is a flow chart of a HVAC equipment control method provided by an embodiment of the present application.

[0040] Such as figure 1 As shown, this embodiment provides a method for controlling HVAC equipment. The execution subject of the method may be a HVAC equipment control device or a functional module based on software and / or hardware. The method at least includes the following steps:

[0041] Step 11. Obtain vibration data of preset structural points in the HVAC equipment in real time.

[0042] Wherein, the HVAC equipment may include, but is not limited to, an air conditioning unit. The above-mentioned preset structural points are weak structural points in the HVAC equipment that are easily affected by vibration and malfunction, and need to be monitored. Taking the air-conditioning unit as an example, the structural points can be welding points, bending points, and valve settings of refrigerant pipes. Points, etc., during implementation...

Abstract

The invention discloses a control method and device for a heating and ventilation device and a heating and ventilation system. The method comprises the following steps that vibration data of a presetstructural point in the heating and ventilation device are acquired in real time; the acquired vibration data are compared with a preset normal range; and the operating frequency of the heating and ventilation device is controlled according to a comparison result. Through the above method, the situation that due to the fact that the vibration is serious, the structure is damaged, and the normal use of the device is influenced can be avoided, the intelligent degree is improved, the fault rate is effectively reduced, the reliability of the device is improved, the service life is prolonged, and the economic loss is reduced.

Description

technical field [0001] The present application relates to the technical field of equipment control, in particular to a method and device for controlling HVAC equipment and an HVAC system. Background technique [0002] At present, with the development of science and technology, the control logic of HVAC equipment has been continuously improved, and the reliability of the electronic control system has also been steadily improved. However, some faults will inevitably occur during the operation of the equipment. It is related to the structural vibration in the process. When the vibration is severe, it will lead to structural damage. For example, welding points, valves, pipeline bending points and other positions are very easy to be damaged by vibration, resulting in equipment failure. Contents of the invention [0003] The purpose of the present application is to provide a HVAC equipment control method, device and HVAC system to solve the problem in the related art that the st...
