Air-Conditioning System in a Green Office Building

Abstract

Green buildings can meet the requirements for building energy-saving and environmental protection policies in most countries. In order to achieve these targets, the priority is given to the design of air-conditioning systems when a green building is designed. Besides, in most green building standards, there are many contents that are related to the air-conditioning systems. For the purpose of achieving more energy-saving potentials of HAVC in buildings, many aspects should be paid attention to, such as the adaptability of an air-conditioning system in different districts and climatic environments, energy consumption of an air-conditioning system in designed full life cycle, system performance at part-load conditions, and so on. Furthermore, after an air-conditioning system is designed, a data acquisition system that monitors the air-conditioning system and analyzes its system performance also needs to be set, in order to ensure that the concepts in the design period have been achieved. Certainly, more energy-saving potentials of the air-conditioning system can be found in the system performance analysis.

In this chapter, the system performance in a specific year is introduced and the relationship among outdoor temperature, temperature settings of heat pump, and system performance is found. Finally, by analyzing the energy consumption of the system, the waste during operation is identified, and then a better operation management strategy of the air-conditioning system may be further proposed.
