摘要

台湾的人口老化问题日益严重;2018年,老年人占总人口的14%以上。老年人的护理质量取决于长期护理机构创造舒适生活空间的能力,同时通过减少电力消耗来确保能源效率,从而为他们提供一个积极、积极的老龄化环境。本研究提出了一种新的热泵系统,该系统在夏季提供冷源,在冬季提供热源。此外,还制定了室内生活空间舒适度所需的空调和通风率,以确保此类机构的护理空间具有高质量。热泵系统安装后的结果如下:(1)热泵系统的性能:热泵冷冻水的入口温度保持在7-10°C,出口温度保持在42-54°C。(2) 能源效率:根据95%的置信区间,年平均用电量为32.65千瓦时/天,是以前用电量水平的32.65%;67.35%的减少与大多数热泵系统的减少相当。(3) 改善室内环境:在最热的情况下,室内温度降低了3°C,相对湿度降至55-65%,处于舒适范围内。热泵系统引入后,通风、空气质量和舒适度显著改善,平均总满意度显著提高。所有的改善都达到了统计学意义。该系统的总体目标是提高长期养老机构的环境质量,使其更健康、更节能。

Developing new heat pump system to improve indoor living space in senior long-term care house
The issue of an aging population is becoming increasingly acute in Taiwan; in 2018, seniors comprised over 14 % of the total population. The quality of care for senior citizens hinges on the ability of long-term care facilities to create comfortable living spaces while ensuring energy efficiency by reducing electricity consumption, thereby providing them with an environment for aging in an active and positive way. This study proposes a new heat pump system that offers a cold source in the summer and a heat source in the winter. In addition, the air-conditioning and ventilation rates required for comfort in indoor living spaces are established to ensure the high quality of the care spaces in these types of institutions. The results after installation of the heat pump system were as follows: (1) Performance of the heat pump system: the inlet temperature of the heat pump chilled water was maintained at 7-10 °C, and the outlet temperature, at 42-54 °C. (2) Energy efficiency: Based on a 95 % confidence interval, the average annual electricity consumption was 32.65 kwh/day, which was 32.65 % of the prior consumption level; the reduction of 67.35 % is comparable to those of most heat pump systems. (3) Improvement of the indoor environment: In the hottest scenario, the indoor temperature was reduced by 3 °C and the relative humidity to 55-65 %, which fall within comfortable ranges. After the heat pump system was introduced, significant improvements in ventilation, air quality and comfort were noted, as well as significant improvement in average total satisfaction scores. All improvements reached statistical significance. The overall objective of the system is to enhance the environmental quality in long-term senior care facilities and make them healthier and more energy efficient.
