Analysis on temperature differences and performance improvement of central air conditioning systems

Analyses the characteristics of conventional central air conditioning systems from the perspective of heat exchange temperature differences, studies the influences of temperature difference on the heat exchange area, transmission and distribution energy consumption and chiller energy consumption. Based on the characters of sensible and latent heat loads, presents the concept of temperature and humidity independent control system, and analyses its temperature differences in different segments. Indicates the methods of improving the performance of fresh air handling process and temperature control process, and analyses the difference of different central air conditioning systems in heat exchange temperature difference and system performance with an office building case study.
