Abstract

The invention provides a control system and a control method for a central air conditioning cold station. The central air conditioning cold station comprises a plurality of cold station device groups. The control system comprises a plurality of control modules. The control modules are correspondingly connected with one or more cold station devices in the cold station device groups, and are used for controlling the operation parameters of the cold station devices. The control modules are also used for sending the parameter demand change values of the cold station device groups to the other control modules correspondingly connected with the cold station device groups when the operation number of the cold station devices in the cold station device groups controlled by the control modules changes, so as to adjust the operation number of the cold station devices in the cold station device groups controlled by the control modules according to the parameter demand change values by the other control modules. Since one control module is only connected with one cold station device, all that is needed is to connect the control modules according to the connection relations between the cold station devices in a water system, and the development period and the human input can be reduced; and moreover, the operation energy efficiency of the central air conditioning cold station can be improved, and the energy consumption of the central air conditioning cold station is reduced.

Description

technical field

[0001] The invention relates to the technical field of air conditioning, and more specifically, to a control system and a control method for a central air conditioning cold station. Background technique

[0002] The central air-conditioning cold station is generally composed of chillers, refrigeration pumps, cooling pumps, cooling towers, valves and control systems, which are mainly used to provide air-conditioning chilled water for public buildings. Among them, the control system is respectively connected with cold station equipment such as chiller, refrigeration pump, cooling pump, cooling tower and valves, and is used for automatic management and control of these cold station equipment, so as to realize the automation of central air-conditioning cold station, so as to reduce manpower and Material resources are invested to improve the energy efficiency level of the central air-conditioning system.

[0003] Such as figure 1 as shown, figure 1 It is a conn...
