Embodiment 1

[0034] The operation control method of the air-conditioning system compressor provided by the present invention will be described below with reference to the accompanying drawings.

[0035] The air-conditioning system compressor operation control method provided by the present invention can be applied to household air conditioners, and can also be applied to air-conditioning systems in other environments, such as shopping malls, ships and other environments, by writing the corresponding program on the main board of the air-conditioning system Implementation, in some embodiments, can also be achieved by installing software, figure 1 An optional flow chart showing the operation control method of the air-conditioning system compressor of the present invention, such as figure 1 As shown, the method may include the following steps:

[0036] S102, obtaining the discharge pressure of the compressor discharge port of the air conditioning system in real time;

[0037] S104, determini...

Embodiment 2

[0076] Based on the operation control method of the air-conditioning system compressor provided in the above-mentioned embodiment 1, the optional embodiment 2 of the present invention also provides an operation control device for the air-conditioning system compressor, specifically, Figure 4 shows an optional structural block diagram of the device, such as Figure 4 As shown, the device includes: a first acquisition unit 42, which is used to acquire the exhaust pressure of the air-conditioning system compressor exhaust port in real time; a first determination unit 44, which is used to determine the exhaust saturation temperature Tc corresponding to the exhaust pressure; The protection unit 46 is configured to adjust the operation of the compressor according to the saturation temperature Tc of the exhaust gas, so that the high-pressure operation process of the compressor is within a normal operation range.

[0077] Further, the high-pressure protection unit includes: a first a...

Abstract

The invention discloses a running control method and device for an air conditioning system compressor. The method includes the steps that exhaust pressure of an exhaust port of the air conditioning system compressor is acquired in real time; exhaust saturation temperature Tc corresponding to the exhaust pressure is determined; running of the compressor is adjusted according to the exhaust saturation temperature Tc, and the high-pressure running process of the compressor is located within the normal running range. The problems that in the prior art, an air conditioning unit runs exceeding the normal running range, so that the service life of a compressor is shortened is solved, the running reliability of the air conditioning unit is improved, and furthermore, the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an operation control method and device for a compressor in an air conditioning system. Background technique [0002] At present, most air-conditioning products only conduct unit reliability tests during unit development. After passing the verification, they do not pay attention to the operation status of the unit compressor. In the subsequent work of the unit, high-pressure operation or low-pressure operation may exceed its own Conditions within the normal operating range, reducing the reliability of compressor operation. [0003] Aiming at the problem in the related art that the air-conditioning unit operates beyond its own normal operating range, resulting in a reduction in the operating reliability of the compressor, no effective solution has been proposed so far. Contents of the invention [0004] The invention provides an operation control method and device for a...
