The invention provides an automatic air-conditioning operation capacity regulation system and method. By employing information including the air-conditioner host ice water inlet and outer water temperatures and operation current etc., a load rate analysis module is established, the operation capacity of each air-conditioner host and the total air-conditioner capacity required by heat balance of building space can be calculated, and a multi-host operation regulation and control method with high energy efficiency and in accordance with the requirement of the space air-conditioner capacity is proposed with the combination of the load rate and a power consumption conversion module. According to the air-conditioner host regulation method, the priority operation sequence and the operation number of air-conditioner hosts can be determined according to the power consumption condition after the operation of the air-conditioner hosts, the air-conditioner operation capacity with low load rate is transferred to other air-conditioner hosts in operation, the air-conditioner hosts can all maintain high load rate and satisfy the requirement of the total operation capacity of the air-conditioners, the operation efficiency tendency is analyzed, and the energy-saving benefit after regulation and control and improvement is predicted.
Description
technical field [0001] The invention relates to an automatic air-conditioning operating capacity adjustment system and method, which simultaneously record the operating load rate of the air-conditioning unit and analyze the operating efficiency trend of the main unit of the air-conditioning unit and predict and adjust the improved energy-saving benefits. Background technique [0002] With the rising awareness of energy conservation and carbon reduction, reducing energy consumption is an important issue. General energy management products mostly use ICT technology to complete the collection of electricity consumption data and then provide control energy equipment or report data, but there is no optimized operation strategy for users with multiple air-conditioning units. Therefore, how to make the power consumption intelligent and automatic operation control mode, and design the energy consumption calculation and analysis method of the air conditioner main unit to help users m...
