双级耦合热泵系统在我国三北地区应用的预测分析

分析了空气／水热泵机组在三北地区运行的可行性，利用双级耦合热泵的运行模拟数学模型预测了系统在三北地区主要城市运行时供暖期内的能源利用效率。结果表明，我国北方除哈尔滨、长春和乌鲁木齐等城市外，其余大部分城市适合应用或可以应用双级耦合热泵系统。

Predictive analysis of applying double stage coupling heat pump systems in north areas of China

Analyses the feasibility of applying air-water heat pump units in northeast, north and northwest areas of China. Predicts the energy consumption of the double stage coupling heat pump system during heating period in major cities of these areas using the running and simulating mathematical model. The results indicate that the system is suitable applied or can be applied in most of north cities except Harbin, Changchun and Urumqi etc.
