中文摘要：

沼气机热泵空调是以农用沼气并辅少量电力作为能源输入,向室内提供冷量或者热量的系统。建立了换热器数学模型、喷水室数学模型、一次回风式空调数学模型,并且定义了评价沼气机热泵空调系统性能的一次能源利用率。通过模型求解,比较了沼气机热泵空调和普通电动热泵空调的能耗情况。结果显示：制冷工况下,沼气机热泵复合式空调系统利用系统余热来实现空气的再热,可达到消除室内余热余湿的目的。系统总的一次能耗最大节能75%。制热工况下,首先通过换热器进行预热,然后通过喷系统热水,进行热湿处理。系统总的一次能耗最大节能71%。沼气机热泵增加了湿处理功能,扩大了沼气机热泵的应用范围。

英文摘要：

The heat pump air condition driven by biogas engine （BHPAC） is a new-style air condition system, which is composed of the heat pump driven by biogas engine （BHP）, the primary heat exchanger, the second heat exchanger, the water spraying chamber and other auxiliary equipment such as fans, water pumps etc. The mathematic model including the primary heat exchanger model, the second heat exchanger model, the water spraying chamber model, the mixed air model and the BHP model, was established to study the BHPAC system. The primary energy ratio for air condition was defined to evaluate the performance of the air condition. The results show that the air condition driven by biogas engine can save more energy than the heat pump air condition driven by electricity engine. The saving primary energy percentage for BHP is 75 % in summer, and the saving primary energy percentage for BHP is 71% in winter. The BHP with the .wet processing can be used in more areas than the common BHP.
