APPLICATION OF AIR SOURCE HEAT PUMP WITH HEAT RECOVERY IN AGRICULTURAL PRODUCTS DRYING PROCESS

摘要

Heat recovery employed to air source heat pump could enlarge the air dehumidification capacity and increase the air temperature entering the drying chamber, Meanwhile, the latent heat by condensing the vapor in high humidity air could be absorbed completely which is particularly effective in the south of China.Compared with the traditional heat pump, the energy consumption is reduced about 30% through drying rice, sausage and fish etc.With heat recovery air source heat pump, the products quality is improved at the same time.
