Heating, ventilation, and air conditioning systems help maintain the appropriate level of thermal comfort and air quality in buildings. To this end, the energy supply of these systems must be guaranteed. However, continuous efforts are required to improve the energy efficiency of this system and reduce greenhouse gas emissions. In the zero-emission building approach, the use of thermoelectric devices has been proposed to meet the heating/cooling needs in the building and help in flexibly changing the operating conditions according to the user's needs. In this study, an experimental setup was developed consisting of a multipurpose thermoelectric system that is directly powered by a solar photovoltaic panel. The heating mode was designed for space heating, whereas the cooling mode was tailored to an adiabatic box that could cool food and beverages. The results of this study will facilitate the practical use of this device in the future by directly connecting the thermoelectric system to the room and evaluating the response of the system to temperature changes requested by the user. This system has a high potential for delivering heating and cooling loads, achieving a coefficient of performance of 1.6 in the heating mode and 0.8–1.1 in the cooling mode. These results are promising given the current need to reduce negative environmental impacts in the building sector yet maintaining the same level of thermal comfort.

供暖、通风和空调系统有助于在建筑物中保持适当的热舒适度和空气质量。为此，必须保证这些系统的能源供应。但是，需要不断努力提高该系统的能源效率并减少温室气体排放。在零排放建筑方法中，已提出使用热电装置来满足建筑物的供暖/制冷需求，并有助于根据用户需求灵活改变运行条件。在这项研究中，开发了一个实验装置，由一个由太阳能光伏板直接供电的多用途热电系统组成。加热模式专为空间加热而设计，而冷却模式是为一个可以冷却食物和饮料的绝热箱量身定做的。通过将热电系统直接连接到房间并评估系统对用户要求的温度变化的响应，这项研究的结果将促进该设备在未来的实际使用。该系统具有提供加热和冷却负载的巨大潜力，在加热模式下实现 1.6 的性能系数，在冷却模式下实现 0.8-1.1。鉴于目前需要减少建筑部门对环境的负面影响，同时保持相同水平的热舒适性，这些结果是有希望的。通过将热电系统直接连接到房间并评估系统对用户要求的温度变化的响应，这项研究的结果将促进该设备在未来的实际使用。该系统具有提供加热和冷却负载的巨大潜力，在加热模式下实现 1.6 的性能系数，在冷却模式下实现 0.8-1.1。鉴于目前需要减少建筑部门对环境的负面影响，同时保持相同水平的热舒适性，这些结果是有希望的。通过将热电系统直接连接到房间并评估系统对用户要求的温度变化的响应，这项研究的结果将促进该设备在未来的实际使用。该系统具有提供加热和冷却负载的巨大潜力，在加热模式下实现 1.6 的性能系数，在冷却模式下实现 0.8-1.1。鉴于目前需要减少建筑部门对环境的负面影响，同时保持相同水平的热舒适性，这些结果是有希望的。
