This requires a water temperature-control system, usually consisting of a water pump, filter, heatexchanger, and valving to control chilled water input.
这就要求一个水温控制系统，通常包括水泵、过滤装置、热交换器、阀门以控制冷却水流量。
2
The dynamic system model is coupled with geothermal heatexchanger model and heatpump unit model, which is based on the conservation of mass and energy.
采用确定性模型法建立了热泵机组的模型，然后通过能量和质量守衡方程序建立了系统动态耦合模型。

Simulates the thermodynamic characteristic of the air side heatexchanger of an air source heatpump under different air temperature and relative humidity.
