Problems solved by technology

In actual operation, changes in the number of internal units in the air conditioning system may cause a mismatch with the number of chillers in operation. If the number of chillers in operation is too large, the entire central air conditioning system will not save energy; and if the number of chillers in operation is too large less, the overall cooling capacity is too small and may not meet the cooling requirements of the system

Abstract

The invention relates to an air conditioning system water chilling unit operation control method and device and an air conditioning system, and belongs to the technical field of air conditioning control. The method comprises the steps that whether operation of the air conditioner system meets a preset loading condition or a preset load shedding condition is judged; if the loading condition is met,according to a first control strategy, an unoperated water chilling unit and channel equipment of the unoperated water chilling unit are selected, starting control is carried out on the selected unoperated channel equipment, and then a starting instruction is issued to the selected unoperated water chilling unit; and if the load shedding condition is met, the running water chilling unit and the channel equipment of the running water chilling unit are selected according to a second control strategy, a shutdown instruction is issued to the selected running water chilling unit, and then closingcontrol is carried out on the selected running channel equipment. By means of the air conditioning system water chilling unit operation control method and device and the air conditioning system, energy-saving and stable operation can be advantageously achieved while refrigeration of the air conditioning system is met.

Description

technical field [0001] The application belongs to the technical field of air-conditioning control, and in particular relates to a method and device for controlling the operation of chillers in an air-conditioning system and an air-conditioning system. Background technique [0002] In the central air-conditioning refrigeration system, the control of the number of chillers in the system is an important control part of the central air-conditioning refrigeration system. In actual operation, changes in the number of internal units in the air conditioning system may cause a mismatch with the number of chillers in operation. If the number of chillers in operation is too large, the entire central air conditioning system will not save energy; and if the number of chillers in operation is too large If the cooling capacity is too small, the overall cooling capacity may not meet the cooling requirements of the system. Therefore, how to control the number of chillers in the central air-...
