项目摘要

The effect of total heat exchanger on the decrease of ventilation load was examined in consideration of daily and annual change of outdoor temperature on each season. It was carried out through the field survey and the experiment chamber test. The influence of heat loss through the duct was evaluated and the amount of total heat recovery including that influence was 60 to 65 % of the amount of heat loss by non-heat exchange ventilation on the reference month of each season. The influence of the airflow from the inlet of the ventilator on indoor temperature and air distribution was also examined on each season. The windbreak plate attached to the inlet decreased thermal discomfort caused by the draft. It was also confirmed that the windbreak plate and the airflow from the indoor unit of air-conditioner gave the complex influence to the indoor environment on summer and winter period.

考虑室外温度的日变化和年变化，研究了全热交换器对降低通风负荷的作用。通过现场调查和实验室测试进行。对通过管道的热损失的影响进行了评估，并且包括该影响的总热回收量为每个季节的基准月的非热交换通风的热损失量的60至65%。研究了不同季节通风机入口气流对室内温度和气流组织的影响。在进气道上加装防风板，减少了气流引起的热不适。同时也证实了防风板和空调器室内机气流对室内环境的影响在夏季和冬季是复杂的。
