Energy Consumption Characteristic Research on Dedicated Outdoor Air System

A series cold water system for fresh air handling units and indoor dry coils based on analyzing the characteristics of Dedicated Outdoor Air System(DOAS) was proposed,and reasonable indoor design parameters were given.All-year cooling load duration curves for fresh air handling units and indoor dry coils were obtained and analyzed by building dynamic cooling load calculation for a hotel standard layer in Guangzhou city.Furthermore,energy consumption characteristics for heat recovery DOAS are analyzed.
