Hybrid ventilation system of residential buildings in hot-summer and cold-winter zone

Analyses the human body’s thermal adaptability in the natural environment, determines the sendible temperature as the control target parameter for hybrid ventilation system. Analyses the sendible temperature range and evaluation level in the natural environment in hot-summer and cold-winter zone, and confirms the air flow range of hybrid ventilation which meets the indoor thermal comfort condition at the different outdoor temperatures. Quantitatively analyses the hybrid ventilation rate and natural ventilation rate of residential buildings by measuring and software prediction. Obtains the satisfied mechanical ventilation rate by comparing the demand ventilation rate with the natural ventilation rate. Determines the control process of hybrid ventilation system under the condition of natural environment.
