Abstract

The invention discloses a central air-conditioning self-optimization intelligent fuzzy control device and a control method thereof. Technological parameters and indoor and outdoor environmental parameters of all control points of a central air-conditioning system are collected, running efficiency of a circulating system and control ends are tracked in real time according to actual load capacity of the system and end cold and hot source requirements, operation cycle of a main machine is optimized and adjusted, operation energy efficiency of each link of the system is comprehensively controlled, so that the system can always run under working conditions of high energy efficiency ratio. Meanwhile, process data, energy consumption data and equipment running data of the central air-conditioning system are summarized to form an intelligent control base, technical process such as analysis and operation is performed through the a central air-conditioning self-optimization intelligent fuzzy controller, new control strategies are generated, on-line upgrading control algorithm and energy-saving potential mining are achieved, energy consumption of the system is optimized, the operation is simplified, so that the operating efficiency of each device of the system is adjusted, and the aims of high efficiency, energy saving and intelligent control are achieved.

Description

technical field [0001] The invention relates to a central air-conditioning self-optimizing intelligent fuzzy control device and a control method thereof, belonging to the technical field of energy efficiency intelligent control. Background technique [0002] As a key energy-consuming device inside a large public building, the power consumption of the central air-conditioning system generally accounts for more than 40% of the power consumption of the entire building. The central air-conditioning unit is designed to meet the maximum cooling and heating capacity of the place of use, but in practical applications, the cooling and heating loads consumed are changing, and generally there is a big difference from the maximum design cooling and heating capacity. The equipment runs for more than 90% of the time in a non-full-load rated state. Traditional central air-conditioning water and air systems generally use valves or air door openings to adjust water and air volumes. The disa...

Problems solved by technology

Traditional central air-conditioning water and air systems generally use valves or air door openings to adjust water and air volumes. The disadvantage of this adjustment method is not only that it consumes a lot of energy, but also that the adjustment quality is difficult to achieve an ideal state, resulting in poor air conditioning comfort. ; Even if some existing central air-conditioning systems use inverters to adjust the speed of pumps or fans to adjust water and air volumes, due to the follow-up of the central air-conditioning load and the single working mode of the control system, the control algorithm is simple, and the control strategy cannot be updated in real time. It can't save energy to the greatest extent, and at the same time, it causes poor air-conditioning comfort in different degrees.
