热泵型新风换气系统在严寒地区实验研究

Experimental Assessment of a Heat Pump Type Fresh Air Ventilation System in Cold Regions

严寒地区冬季需要供暖来保证室内温度,在封闭的房间为了保持室内空气品质需要通风换气,加热新风需要消耗热量,采用传统的新风/排风热交换装置可以回收部分排风热量,但仍有部分热量排至室外。实验利用热泵原理,吸收热回收器排风中的废热,并将这部分热量转移到进入室内的新风中,从而在满足空气品质的同时进一步降低了新风能耗。

In cold regions, heating is required to ensure indoor temperature in winter, in a closed room in order to maintain indoor air quality needs ventilation, heating fresh air needs energy consumption. The traditional air/exhaust heat exchange device can recover part of the exhaust heat, but there are still a part of the heat discharged to the outside.In this paper, by using the experimental of heat pump principle, to absorb the waste heat of exhaust air of the heat collector, and transferring the heat to fresh air into the room, to meet the air quality and further reduce the energy consumption of fresh air at the same time.
