A large building or a factory with an open office area is commonly used for
a centralized chiller plant system (CPS), including a chiller, chilled water pump,
condensing pump, and cooling tower. A centralized control system called chiller plant
management system (CPMS) has been installed to reduce complex operations and allow
the system to operate according to the settings for appropriate working time. Even
though there is an installation guide from developing countries, installing hardware and
software in Thailand still lacks clear standards or guidelines. As a result, the
communication speed between the control system and the device is inappropriate. It
leads to restrictions on data transmission and difficulty assessing performance with
appropriate data. As a guideline for future development, this research proposes
development for evaluating hardware, software and CPMS performance (characteristic
quantity (CQ) and heat balance). It is divided into hardware checks according to
aggregate communication and sub-communication to obtain adequate data for the
system performance evaluation. The guidelines have been developed by recommended
equipment manufacturers widely used in Thailand. It is used in three large-scale
commercial buildings. It was found that the communication device supports data
transmission every 15 minutes, there is no communication signal interruption, and the
software system is suitable for recording CPS data to support: (1) energy-saving
assessment and (2) process of ecU9zzVtYvaluating the performance of the CPS system
in terms of CQ analysis and heat balance theory. The finding process can be used to
evaluate exiting CPMS performance before the improvement.
