Problems solved by technology

[0002] As there are more and more requirements for the normal and comfortable operation of multi-connected air conditioners under low temperature conditions, there are also many low temperature air conditioners on the market. It is in a cold area where the temperature is below -15 degrees for a long time), and then the sudden start-up will often lead to unstable operation of the air-conditioning system, and the unit may fail to operate.
[0003] Aiming at the technical problem of ensuring the stable start-up of the air-conditioning unit after the low-temperature working condition is introduced into the air-conditioning unit, no effective solution has been proposed so far

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0037] Considering that after the existing unit is placed under low temperature conditions (for example: below -15 degrees) for a long time, when starting up, the temperature is often low and the pressure parameter of the system is relatively low, and the unit often appears after a short period of operation. There will be a situation of low-voltage protection and shutdown, so that the heating demand cannot be met.

[0038] In the embodiment of the invention, it is mainly aimed at this working condition. When it is detected that the unit needs to be turned on, the system pressure and electronic ...

Abstract

The invention provides an air conditioner unit control method and an air conditioner unit control device. The air conditioner unit control method comprises the following steps: after a situation that an air conditioner unit has a starting-up heating requirement is detected, a pressure value and an ambient temperature of the air conditioner unit are detected; and output power of a compressor and / or the opening of an electronic expansion valve of the air conditioner unit are / is controlled according to the ambient temperature and the pressure value. The technical problem that fluctuation of service exists under a low temperature working condition introduced by an air conditioner is solved, and the technical effect that the starting-up stability of the air conditioner unit is effectively ensured is achieved.

Description

technical field [0001] The present invention relates to the technical field of equipment control, in particular to an air conditioning unit control method and device. Background technique [0002] As there are more and more requirements for the normal and comfortable operation of multi-connected air conditioners under low temperature conditions, there are also many low temperature air conditioners on the market. It is in a cold area where the temperature is below -15 degrees for a long time), and then the sudden start-up will often lead to unstable operation of the air-conditioning system, and the unit may fail to operate. [0003] Aiming at the technical problem of ensuring the stable start-up of the air-conditioning unit after the low-temperature working condition is introduced into the air-conditioning unit, no effective solution has been proposed so far. Contents of the invention [0004] An embodiment of the present invention provides a method for controlling an air-...
