摘要

目标。这项工作的目的是为设计和制造使用热管的热交换器提出实用建议,这种热交换器可广泛用于各种设施的供暖、通风和空调系统。方法。研究基于热力学分析方法、制冷和低温技术、空调和生命支持系统过程和对象的全尺寸和计算建模。结果。在通风、供暖和空调系统中使用和设计热管热交换器的工作中研究的实用建议的实施,将大大节省用于加热和/或冷却供暖、供暖和空调系统所服务房间的空气的能源。为了减少建筑物中的热量损失,必须保持空气平衡,并通过有组织地引入外部空气来补偿排出的空气,从而利用排出的空气中的热量进行加热。结论与基于乙二醇换热器的热交换器相比,使用热管的再生器能耗更低,几乎无需维护,而且由于设计中没有需要电力的泵装置,因此更加节能。同时,由于需要遵守严格的卫生标准,热管再生器的供气和排气通风流完全分离的能力得以保留,这在医疗机构中需求量极大。

Calculation of a heat exchanger using heat pipes in the exhaust air heat recovery system
Objective. The purpose of the work is to develop practical recommendations for the design and manufacture of a heat exchanger using heat pipes, which could find widespread use in heating, ventilation and air conditioning systems at facilities for various purposes. Method. The research is based on methods of thermodynamic analysis, full-scale and computational modeling of processes and objects of refrigeration and cryogenic technology, air conditioning and life support systems. Result. The implementation of the practical recommendations studied in the work on the use and design of heat exchangers using heat pipes in ventilation, heating and air conditioning systems will provide significant savings in energy spent on heating and/or cooling the air supplied to the room served by the HVAC system. To reduce heat loss in a building, it is rational to maintain air balance and compensate for the exhaust air with an organized influx of outside air, to heat which the heat of the removed exhaust air is utilized. Conclusion. Compared to a heat exchanger based on a glycol recuperator, a regenerator using heat pipes is less energy-intensive, requires virtually no maintenance, and is also more energy efficient due to the absence of a pumping device that requires electricity in the design. At the same time, the ability to completely separate the supply and exhaust ventilation flows of the regenerator on heat pipes is preserved, which is extremely in demand in medical institutions, due to the need to comply with strict sanitary standards.
