Air conditioner and air conditioner load control method and device thereof

Abstract

The invention discloses an air conditioner and an air conditioner load control method and device thereof. The method comprises the steps that target air supply temperature input by a user is received;the current air outlet dry bulb temperature and the current air outlet wet bulb temperature are acquired; and the current unit load is adjusted according to the target air supply temperature, the current air outlet dry bulb temperature and the current air outlet wet bulb temperature. According to the air conditioner and the air conditioner load control method and device thereof, by adopting combined deviation control over the wet bulb temperature and the dry bulb temperature, the relation between the air supply temperature and the actual output load can be precisely determined, therefore, theuser requirement and the actual unit load are in a good corresponding relation, and then a unit runs more stably.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to an air conditioner and its air conditioner load control method and device. Background technique [0002] At present, a large number of commercial water-cooled chillers with large cooling capacity and frequency conversion have appeared in the market. From the perspective of load control, most of the control schemes are relatively simple, and they are made for a single control target. In this case, it is indeed possible from the perspective of unit design and manufacturing. It saves a lot of effort, but from another aspect, that is, the user experience and control sensitivity are not particularly good. [0003] For example, the air supply temperature deviation control currently used by many units directly controls the supply air temperature target. Of course, this control mode can be used. Its mode is simple and directly controls the output load, but the problem is that air i...

[0002] At present, a large number of commercial water-cooled chillers with large cooling capacity and frequency conversion have appeared in the market. From the perspective of load control, most of the control schemes are relatively simple, and they are made for a single control target. In this case, it is indeed possible from the perspective of unit design and manufacturing. It saves a lot of effort, but from another aspect, it is not particularly good in terms of user experience and control sensitivity.

[0003] For example, the air supply temperature deviation control currently used by many units directly controls the supply air temperature target. Of course, this control mode can be used. Its mode is simple and directly controls the output load, but the problem is that air is different from a single-phase body such as water. , there are two indicators of humidity and dryness, these two indicators determine the enthalpy and load output at the same time
