Summary:The control systems of the common central air conditioning system are the combination of three key elements: technology, economics and safety. This article describes the four common types of common central air conditioning systems: water resource and heat pump system, air resource and cooling/heating water system, gas burning system, and VRV system. Through the analysis of the common control systems, pneumatic control system, electronic control system, the HSE assessment for those systems is approached. From four aspects: outside air control, heating control, cooling control and competed systems, this article probes into the principle for HSE assessment and its applications. Finally, the common two application examples are discussed: abnormal phenomena diagnosis for driving part of electronic dilatometer in indoor unit, and overload treatment of air compressor and thermal sensor in outdoor unit.
