Description
Technical Field
The invention belongs to the technical field of central air conditioner control, and particularly relates to a central air conditioner full link coordination control system.
Background
The central air-conditioning system consists of a plurality of subsystems such as a machine room cold and heat source group control system, a fan coil group control system, a fresh air handling unit control system, an indoor environment monitoring system, a meteorological station and other related systems, and the subsystems are greatly different in equipment type, control logic, communication mode and the like, so that the subsystems are usually controlled independently. However, functionally, the subsystems of the central air-conditioning system are associated with each other, and if the subsystems or devices of the central air-conditioning system operate independently and do not communicate with each other, the overall efficiency of the central air-conditioning system is low, and the experience is poor. For example, the machine room cold and heat source group control system and the fan coil group control system are not related to each other in control, so that the two systems are not started synchronously, cold and heat of the machine room are wasted when the machine room equipment is started and the fan coil is not started, or the fan coil is wasted in idling when the fan coil is started and the machine room cold and heat source equipment is not started, and even if the two systems are started, the problem of unbalanced supply and demand is likely to exist. Similar problems exist in other subsystems in the air conditioning system, so that the problems of low air conditioning efficiency and poor user experience are caused.
