在办公楼中,通过通风系统的排气,损失掉大量的热能。国内外的经验表明,将排气热量合理地用于加热进气,可使用于进气的热量节约40％。当进气装置与排气装置布置在大楼的不同区域或两者距离超过20m时,建议采用有中间载热剂的水泵循环热回收系统。 在苏联国家建委的一幢新建的办公楼中,进气装置设在地下室,有12个集中式调
In the office building, a large amount of heat energy is lost through the ventilation of the ventilation system. Experience at home and abroad shows that the exhaust heat can be reasonably used to heat the intake air, which can save 40% of the heat used for intake air. When the intake and exhaust devices are located in different areas of the building or when the distance between the two devices exceeds 20 m, a circulating pump heat recovery system with an intermediate heat carrier is recommended. In a newly-built office building of the Soviet State Construction Commission, the air intake unit is located in the basement and there are 12 centralized adjustments.
