Embodiment 1

[0029] see figure 1 , a central air-conditioning output controller, including a main controller 1, a soft starter 2, a compressor unit 3, and a human-computer interaction interface 4, and the main controller 1 interacts with the soft starter 2 and the human-computer interface respectively The interface 4 is electrically connected, the soft starter 2 is electrically connected with the compressor unit 3, the compressor unit 3 includes several compressors, the compressor unit 3 is controlled and started by the soft starter 2, and the main The controller 1 is also electrically connected to a temperature sensor 5 and a heater 6; the man-machine interface 4 is used to control the main controller 1, and the soft starter 2 is used to soft start the compressor unit 3 to avoid current shock. When the central air conditioner starts, the temperature sensor 5 detects the indoor temperature. When the indoor temperature is higher than a predetermined value, the main controller 1 controls the...

Embodiment 2

[0042] see figure 2 The difference between this embodiment and Embodiment 1 is that it also includes a dust sensor 10 and a dust remover 9, and the dust sensor 10 and the dust remover 9 are respectively electrically connected to the main controller 1. When the dust sensor 10 detects the indoor When the dust content exceeds the predetermined value, the main controller 1 will start the dust remover 9 to remove dust in the room; when the dust sensor 10 detects that the dust content in the room is lower than the predetermined value, the dust remover 9 will stop working.

[0043] The central air conditioner output controller and its control method proposed by the present invention have the function of dust removal, reduce the influence of dust on the central air conditioner, and prolong the service life of the central air conditioner.

Abstract

The invention provides a central air conditioner output controller and a control method thereof. The central air conditioner output controller comprises a main controller, a soft starter, a compressorunit and a man-machine interaction interface. The main controller is electrically connected with the soft starter and the man-machine interaction interface separately, and the soft starter is electrically connected with the compressor unit. The compressor unit comprises a plurality of compressors, the compressor unit is controlled to be started through the soft starter, and the main controller isalso electrically connected with a temperature sensor and a heater. When a central air conditioner is started and the indoor temperature is higher than a preset value, the compressor unit is startedto work. When the indoor temperature reaches the preset value, a part of the compressors in the compressor unit are shut down. The problems that an existing variable-frequency central air conditioneris high in use cost and short in service life are solved, and the problem that hard start of a constant-frequency central air-conditioning compressor cannot adapt to environment changes to adjust theoutput power stage by stage and reduce the energy consumption is solved.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning output control, in particular to a central air-conditioning output controller and a control method thereof. Background technique [0002] Temperature control is very important for the production of high-quality liquor. Its influence starts from the maturation process of raw materials and continues to fermentation, aging and bottling of liquor. If the temperature that guarantees the quality of liquor cannot be maintained during the brewing process of baijiu, the highest quality liquor will not be brewed, even if the high-quality raw materials of the best varieties are used. At present, central air-conditioning is basically used for temperature control in wine-making workshops. For many years, various enterprises and institutions in my country have relatively extensive management of central air-conditioning, and the temperature setting of air-conditioning is not reasonable, resulti...
