设计了一种新型复合冷却系统,利用中间板式换热器将机械制冷和泵驱动回路热管结合在一起,可以实现3种工作模式:热管模式、制冷模式和双模式。实验结果表明,在相应的温度范围内,3种工作模式的冷却效果显著。当室内外温差分别为10℃和18℃时,热管模式的能效比(EER)分别为5.6和10.4;复合系统的全年能效比(AEER)可以达到8.3,是传统型空调COP的2倍多。针对某小型全年用冷房间的模拟计算发现,室内温度为25℃时,在国内不同气候区4个城市使用复合系统的节能率分别为18.0%,18.8%,31.5%,49.4%。
A new type of compound cooling system is designed. The intermediate plate heat exchanger combines the mechanical cooling with the pump driving circuit heat pipe to realize three working modes: heat pipe mode, cooling mode and dual mode. The experimental results show that in the corresponding temperature range, the cooling effect of the three working modes is remarkable. When the temperature difference between indoor and outdoor is 10 ℃ and 18 ℃ respectively, the energy efficiency ratio (EER) of the heat pipe mode is 5.6 and 10.4, respectively. The AEER of the composite system can reach 8.3, which is more than twice that of the traditional air conditioning COP . According to the simulation of a small cold year-round room, the energy-saving rates of the composite system in four cities in different climatic regions in China are 18.0%, 18.8%, 31.5% and 49.4% respectively when the indoor temperature is 25 ℃.
