Study on the design optimization of air conditioning system with dual cooling source temperature and humidity independent control

The division of air conditioning loads was performed in the view of entropy. The selection of the design parameters and the calculation of the air conditioning loads of dual temperature cold source air conditioning system were discussed based on different fresh air processing methods. Systematic optimization was conducted, which follows the principle of “high entropy load can be eliminated with high temperature cold source, while low entropy load can be eliminated with low temperature cold source”. In addition to high temperature cold source cooling, dehumidification cycle combining high and low temperature cold sources was proposed. A dual temperature cold source energy consumption model was established. Numerical simulation calculation was employed to obtain the optimum dehumidification temperature and heat removal cold source temperature.
