Abstract

The invention discloses a multifunctional frequency conversion central air-conditioning experimental platform, which comprises a refrigerating system, a control system and a simulated room, wherein the refrigerating system comprises a refrigerating unit, a chilled water system and a cooling water system; the control system comprises an upper computer, a lower computer and a frequency converter; amonitoring module in the upper computer is used for acquiring operating temperatures, pressure and flow signals of the experimental platform through the lower computer and transmitting a control command to monitor operation of the refrigerating system through the lower computer or the frequency converter; a matrix laboratory (MATLAB) module in the upper computer can execute an optimization control algorithm, and the MATLAB module and the monitoring module perform data exchange through a dynamic data exchange (DDE) mechanism or an object linking and embedding standard for process control (OPC); and the refrigerating unit comprises a frequency conversion compressor, a condenser, and an air-cooled evaporator and a water-cooled evaporator which are connected in parallel. By the experimental platform, refrigerating effects of the air-cooled evaporator, the water-cooled evaporator and a varied refrigerant volume (VRV) multi-air-conditioning system can be researched simultaneously, and a verification platform can be provided for a large frequency conversion central air conditioner to execute an energy-saving optimal advanced control strategy.

Description

technical field [0001] The invention relates to a multifunctional frequency conversion central air conditioner experiment platform. Background technique [0002] With the development of my country's economy, central air-conditioning has been more and more widely used in high-rise buildings such as hotels, hospitals, and large shopping malls. However, the wide application of central air-conditioning brings a lot of energy consumption, accounting for a large part of building energy consumption. In addition, at this stage, the installed capacity of central air-conditioning in my country is often higher than the required load, and most of them have not implemented advanced control of energy-saving optimization, resulting in serious energy consumption. Therefore, it is of great significance to develop a multi-functional frequency conversion central air-conditioning experimental platform capable of monitoring and provide a verification platform for the implementation of energy-sa...
