Energy-saving control method of central air conditioner

Abstract

The invention discloses an energy-saving control method of a central air conditioner. The energy-saving control method comprises the specific steps that a system is initialized, a sensor module collects working condition parameter data of the switched-on air conditioner system, and the collected working condition parameter data is transmitted to a data collecting module; the data collecting module converts analog signals in the working condition parameter data into digital signals, and sends the working condition parameter data converted into the digital signals to a data processing module; the maximum system total power and the current system total power are compared; an equipment control module judges whether a refrigerating water pump or a cooling water pump needs to be additionally switched on or switched off or not for the central air conditioner system under the working condition; the system continues to be detected and analyzed. The energy-saving control method is easy and convenient to implement and low in cost, the use time of motors is reasonably distributed, abrasion to the motors is relieved, the average service life of the motors is prolonged, the function of fault detection is achieved, losses caused by faults are reduced, and maintenance of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of energy-saving control, in particular to an energy-saving control method for a central air conditioner. Background technique [0002] As an important part of the building system, the central air-conditioning system accounts for a large proportion of the energy consumption and electricity of the entire building system. According to statistics, the energy consumption of the construction industry accounts for 30% of the country's total energy consumption, and the power consumption of the air-conditioning system accounts for 30% of the country's total energy consumption. 70% of the energy consumption of the entire building accounts for about 18% of the company's total electricity consumption. With the demand for building humanized services, this number will continue to grow. Therefore, the energy saving of the air conditioning system is of great significance and effect to reduce the energy consumption of the b...

Problems solved by technology

In addition, the central air-conditioning energy consumption management is mainly based on the data center system management methods and strategies to achieve energy-saving purposes, but the traditional data management mode is to control the system equipment by pre-defining the parameters of the air-conditioning system to achieve the overall energy-saving purpose. The system structure is complex, and the operating conditions are changing in real time. The method of customizing the system energy-saving strategy by relying on fixed parameters cannot make the system always run in the best energy-saving state, and the continuous availability of fixed parameters is poor.
