An air conditioner energy-saving optimization control method and device

Abstract

The present invention is applicable to the technical field of control, and provides an air-conditioning control method and device. The method includes: collecting and storing the current operating parameters of chiller units, chilled water pumps, and cooling water pumps of the air-conditioning system according to a preset period; The current operating parameters and the operating parameters to be adjusted input by the user determine the energy consumption increment of the air conditioning system relative to the current operating state under the operating state of the operating parameters to be adjusted; when the energy consumption increment is less than zero, according to the set The operating parameters to be adjusted adjust the operating state of the air conditioning system. The air-conditioning control method and device provided by the present invention adjust the air-conditioning system according to the operating parameters to be adjusted when the energy consumption increment is less than zero, so as to realize energy saving and easy implementation.

Description

technical field [0001] The invention belongs to the technical field of control, and in particular relates to an air conditioner control method and device. Background technique [0002] With the gradual improvement of users' requirements on the indoor environment of buildings, the use of air conditioners is becoming more and more popular, and the energy consumption of air conditioners is also increasing day by day. In the entire building energy consumption, the energy consumption of the air conditioning system usually accounts for 40%-50%. [0003] Taking a central air-conditioning unit building with electric refrigeration as an example, the core equipment of the central air-conditioning unit mainly includes chiller units, chilled water pumps and cooling water pumps. The water pump is sent to the terminal equipment to exchange heat with the indoor air, absorb the heat in the room, and remove the excess moisture in the indoor air at the same time to meet the heat and humidity...

AI Technical Summary

Problems solved by technology

In the existing technology, some methods may be feasible under stable laboratory conditions, but in the actual operation process, since all the equipment in the air conditioning unit is in continuous operation, the cooling load and weather parameters will also change at any time. The actual value of the parameters obtained is not regular, and the energy consumption model cannot be optimized by adjusting the energy consumption model through the existing control method, and may even produce the opposite effect. Control is critical to reducing overall building energy consumption
