Abstract

The invention provides an air conditioner load adjusting control method and device. The method comprises the steps of counting historical operation parameters of an air conditioner unit, specifically,the operation parameters include the output load of a compressor; determining the predicted operation parameters of the air conditioner unit at the next period of time of the current moment, specifically, the predicted operation parameters include the predicated compressor output load and the predicted compressor fan frequency; obtaining the current operation parameters of the air conditioner unit; and controlling the start and stop or the operating state of the air conditioner unit according to the predicated operation parameters and the current operation parameters. According to the method,by predicting the air conditioner load in advance and adjusting the unit in advance, the unit load is adjusted stably, the temperature fluctuation of an air conditioner of a user is small, the effectof energy saving during operation of the whole unit is achieved, and thus the technical problems that an existing method causes large fluctuation during adjustment of the air conditioner load and delay exists during adjustment of the air conditioner load are solved.

Description

technical field

[0001] The present invention relates to the technical field of air conditioning control, in particular to an air conditioning load regulation control method and device. Background technique

[0002] For areas such as subways, there are periodic changes in the air-conditioning load, and the changes in the air-conditioning load are regular. At present, considering energy saving and installation space in the subway field, water-cooled direct-expansion air-conditioning units are used to replace the air-conditioning scheme of chillers and combined cabinets, which has gradually become the mainstream.

[0003] The existing water-cooled direct expansion air-conditioning unit adjusts the air-conditioning load mainly by detecting the indoor ambient temperature. This control method has hysteresis in the adjustment of the compressor when the load is adjusted, which will lead to the problem of slow response to the indoor temperature; Moreover, due to the hysteresis adjus...
