The experimental result show that the temperature efficiency of rotary - switch regenerator is about 88 % and the thermal efficiency is about 77 %
2.
Evaluates and compares the workshop performance by velocity asymmetry coefficient ku , temperature asymmetry coefficient ki , the age of air , the temperature efficiency 77 and pmv - ppd index
3.
Simulation for different types of air distributions the 3 - d distributions of airflow and tenperature fields in large space are numerically calculated using the software of fluent . through comparing the result of simulation , thinks that the delaminated air conditioning is better than the one of middle supply - up return air distribution . the air supply of low sidewall has large temperature efficiency and can supply the air with low temperature , as is a considerable type of air distribution
