地下水源热电热泵的应用研究

Applied research of a ground water thermoelectric heat pump system

建立了以地下水为热源的热电热泵系统的数学模型 ,并根据热电材料的技术性能对该系统作了计算机模拟分析 ,比较计算结果与进水温度和流量相同的传统地下水源热泵系统发现 ,热电热泵在制冷工况特别是地下水温低于 1 8℃时具有很强的竞争力 ,但制热性能较差 。

Develops a mathematical model of the system and simulates it with computer based on the state of the art performance of the thermoelectric material, compares the results with those of a conventional ground water heat pump system under the identical inlet water temperature and water flow rate and finds that the thermoelectric system is more competitive especially when the ground water temperature is under 18 ℃ but much poorer in heating performance leading it to be suitable for applications with primary heating demand.
