分析了中国夏热地区的室外气候条件,对于冬季,有近乎100%的时间可以采用全新风模式,而过渡季节会有一半左右的时间可以采用全新风模式,从而全年可以减少30%~60%的人工冷源运行时间。通过对焓值控制和温度控制2种调控模式的分析,研究了不同室内负荷强度、不同通风量和不同室内空气温湿度设定值条件下的调控方案。研究发现:室内负荷越大,采用全新风模式的节能效果越好;送风量宜设置为6~8 h-1;室内空气参数对节能效果影响很大,考虑到室内外温差对人体热舒适的影响,可以考虑不同季节不同的室内空气参数设置;对于调控模式,冬季和过渡季节可采用焓值控制模式;夏季宜采用温度控制模式。采用全新风模式,每年可以实现100~180kWh/m2的节能效果,从而产生30~50 kg/m2的碳减排量。
Analyzed the outdoor climatic conditions in summer and hot summer in China, almost 100% of the time can use the fresh air pattern in winter, and about half of the transitional season can adopt the new fresh air pattern, which can reduce 30% ~ 60% % Artificial cold source running time. Through the analysis of two control modes of enthalpy control and temperature control, the control schemes under different indoor load intensity, different ventilation rate and different indoor air temperature and humidity settings were studied. The results show that the bigger the indoor load is, the better the energy-saving effect is. The air supply should be set at 6-8 h-1. The indoor air parameters have a great influence on the energy-saving effect. Considering the difference between indoor and outdoor temperature, Of the impact of different indoor air parameters can be set in different seasons; for the regulation mode, winter and transitional season can be used enthalpy control mode; summer should adopt temperature control mode. With the all-new wind mode, energy saving of 100 ~ 180kWh / m2 can be achieved every year, resulting in a carbon emission reduction of 30 ~ 50 kg / m2.
