Abstract

In winter, offices use heat pumps, electric heaters, and blowers to stay warm, but these use traditional energy that is not sustainable or eco‐friendly. To meet the requirements of thermal comfort, an environmentally friendly and self‐sustainable system was developed at Madhav Institute of Technology and Science in Gwalior, India. This system includes a heat exchanger, a flat plate collector, an evacuated tube collector, and a pump. Two versions of the system were tested: one with a heat exchanger and an evacuated tube collector (HEWETC) and another with a heat exchanger and a flat plate collector (HEWFPC). The results showed that the HEWETC system is better at heating the room and has higher efficiency compared to the HEWFPC system. The HEWFPC system is 12% efficient, while the HEWETC system is 21% efficient. The room stayed at a constant temperature of 26.3°C all day. The HEWETC and HEWFPC systems provided 0.46 and 0.55 MJ of heat to the room, respectively. During the heating season, the solar heat collected was 8030.38 kWh, and electricity used was 5229.7 kWh. The HEWETC system proved to be effective and suitable for heating the building.

独立式混合主动太阳能室内供暖系统的能耗分析

冬季，办公室使用热泵、电暖器和鼓风机来取暖，但这些设备使用的都是不可持续或不环保的传统能源。为了满足热舒适度的要求，印度瓜里奥尔的马达夫技术与科学学院开发了一套环保且可自我维持的系统。该系统包括一个热交换器、一个平板集热器、一个抽真空管集热器和一个泵。对该系统的两个版本进行了测试：一个是热交换器和真空管集热器（HEWETC），另一个是热交换器和平板集热器（HEWFPC）。结果表明，与 HEWFPC 系统相比，HEWETC 系统的房间加热效果更好，效率更高。HEWFPC 系统的效率为 12%，而 HEWETC 系统的效率为 21%。房间全天恒温 26.3°C。HEWETC 和 HEWFPC 系统分别为房间提供了 0.46 兆焦耳和 0.55 兆焦耳的热量。在供暖季节，收集的太阳能热量为 8030.38 千瓦时，用电量为 5229.7 千瓦时。事实证明， HEWETC 系统可以有效地为建筑物供暖。
