热电制冷供热机组（TCHU）是一种利用热电现象作为建筑物供热制冷系统的创新技术。在TCHU中，直流（DC）电流为热电设备（TE）热泵系统提供电力，该系统可以根据电流在一个方向或另一个方向上传递热量。在本研究的现阶段，我们已利用商用的热电技术，研制出第二个热电联产装置的原型。在这种情况下，研究了16个TE模块的垂直配置作为住宅建筑供暖和制冷系统的潜在应用。开发了不同的夜间测试来评估新系统在真实的条件下的性能，并确定这些TE模块在不同电压下运行时的性能系数。不仅研究了制冷模式，还研究了加热模式，根据实测数据，证明了该系统可以成功地安装在建筑物中作为供暖或制冷系统。测试证实了电池两侧温差的巨大相关性，特别是在制冷模式下。此外，还进行了一些理论分析，以找出最合适的结构，使机组在制冷和制热时都能获得最佳的性能系数（COP）。
A Thermoelectric Cooling-Heating Unit (TCHU) is an innovative technology that uses the thermoelectric phenomena as a heating–cooling system for buildings. In TCHU, a direct current (DC) electrical current supplies the power to a Thermoelectric Equipment (TE) heat-pump system, which can transfer heat in one direction or another depending on the current flow. The unit is integrated in the building envelope.At this stage of the study, a second prototype of TCHU has been developed using commercially available TE technologies. In this case, a vertical configuration of 16 TE modules is studied for their potential application as a heating and cooling system for residential buildings.Different nocturnal tests have been developed to evaluate the performance of the new system under real conditions and to determine the coefficient of performance for these TE modules when operating under different voltage regimes. It has been studied not only the cooling mode but also the heating mode.Based on the measured data, it has been demonstrated that the system can be successfully installed as a heating or cooling system in buildings.Tests have confirmed the huge relevance of the temperature difference between the two sides of the cells, taking especial relevance in the cooling mode. It has also been demonstrated that for the cooling mode it is better to work with low voltage values.Besides, some theoretical analyses have been developed in order to find out the most suitable configuration to obtain the best Coefficient of Performance (COP) of the unit in both cooling and heating.
