Abstract

The invention provides an independent primary air system provided with a heat pipe exchanger. The independent primary air system is characterized by comprising a precooling unit, a cooling dehumidification unit, a reheating unit and an air supply unit. The precooling unit, the cooling dehumidification unit, the reheating unit and the air supply unit are sequentially arranged between an inlet and an outlet of the primary air system; the air supply system is arranged on the outlet of the primary air system. Primary air is precooled through an evaporator side of the heat pipe exchanger; the preprocessed primary air is cooled again through the cooling dehumidification unit; the primary air is bent through an air pipe and then heated again through a condenser side of the heat pipe exchanger; the processed air is sent indoors through the air supply unit, and indoor temperature and humidity are controlled to be 26 DEG C +/-0.5 DEG C and 50%+/-1%. The heat pipe exchanger of the independent primary air system achieves heat recovery in the precooling unit and the reheating unit, heat exchange efficiency is high, extra energy loss is avoided, and discharged heat can be recovered to the maximum; indoor air quality is improved; finally an air-conditioning system can save energy by 6%-9%.
