Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] In the embodiment of the present invention, such as figure 1 As shown, the refrigerant pipeline of the air conditioner includes an exhaust pipeline 1 and a return air pipeline 2. At the position where the exhaust pipeline 1 is connected to the exhaust port 31 of the compressor 3, there is a The high-pressure pressure switch 100 (when the high-pressure pressure switch 100 is closed, the exhaust pipeline 1 is turned on; when the high-pressure pressure switch 100 is disconnected, the exhaust pipeline 1 is turned off), at the gas return port of the gas return pipeline 2 and the compressor 3 32 ...

Abstract

The invention belongs to the technical field of controlling air conditioners, and provides an air conditioner, a method and a device for refrigerant pipeline pressure monitor and system control thereof. In the running process of the air conditioner, an output signal of a high pressure switch or output signals of the high pressure switch and a low pressure switch are detected based on a working state of the air conditioner; when it is detected that the high pressure switch continuously outputs a high pressure overpressure signal within a preset time interval and / or the lower pressure switch continuously outputs a low pressure overpressure signal within the preset time interval, a compressor is controlled to stop working, and the compressor is controlled to start working again after a preset period, accordingly controlling the compressor to stop working for the preset period and to start working again when the refrigerant pipeline is overpressured, thereby preventing the compressor from being damaged by heating, increasing the system running reliability of the air conditioner, and reducing the failure rate of the air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air conditioning control, and in particular relates to an air conditioner and its refrigerant pipeline pressure monitoring and system control method and device. Background technique [0002] At present, the air conditioner has been widely used in various climatic conditions, and it can cool or heat the indoor space. When the temperature is too high, the pressure of the refrigerant pipeline in the air conditioner will also increase accordingly, causing leakage of refrigerant at some joints in the refrigerant pipeline due to excessive pressure, which will cause the compressor to be damaged and burned due to severe heat. key components, resulting in unstable operation of the air conditioner, reducing the reliability of the system operation of the air conditioner, and at the same time leading to an increase in the failure rate of the air conditioner. Contents of the invention [0003] The purpose of the pr...
