Abstract

The invention relates to an energy efficiency control terminal and method focused on optimized operation of a central air-conditioning host system. The energy efficiency control terminal is based on an embedded development and is characterized in that an embedded hardware platform mainly consists of a central processing unit, a sampling control module, a communication module, a storage module and a man-machine interaction module; an embedded software system comprises a device driving layer, a system operating layer, a communication protocol layer and an application layer. An optimal control method of the central air-conditioning host system comprises the steps of respectively configuring a host energy-efficiency control terminal, a chilled water pump energy-efficiency control terminal and a cooling water pump energy-efficiency control terminal, and mutually cascading and cooperatively operating the three terminals, wherein a power constant value controller and a temperature difference constant value control for optimizing the energy efficiency of an air-conditioning system are arranged in each terminal, and a voltage constant value controller for guaranteeing the stable operation of a motor is also arranged in each terminal.

Description

technical field [0001] The invention belongs to the field of intelligent electricity utilization, and in particular relates to an energy efficiency control terminal and a control method for optimizing operation of a central air-conditioning host system. Background technique [0002] With the progress of society, electricity consumption continues to increase, and energy consumption is becoming more and more serious, which not only brings huge pressure on energy and environmental protection, especially the sharp deterioration of smog weather in the past two years, energy conservation and emission reduction to protect the environment become more urgent. Electric power consumption is mainly concentrated in industrial users and commercial building users. In addition to production equipment being the main force of energy consumption, the second is air conditioning energy consumption. For comprehensive building energy consumption, HVAC energy consumption accounts for up to 60% % o...
