中文摘要：
根据重庆地区地热水的水温、水质，结合不同用户对温度需求的不同，对重庆市某地热水增／降温耦合系统示范工程进行系统设计，采用水源热泵技术对地热水进行增／降温处理。介绍系统的工艺流程和设备。提出空调回水余冷利用技术，实现“大温差、小流量”输配系统的设计，降低输配系统能耗，提高蒸发器进水温度，提高水源热泵机组的运行能效。
英文摘要：
According to the water temperature and water quality of geothermal water in Chongqing re- gion, the demonstration project of a geothermal water heating/cooling coupling system is designed combined with different user requirements for temperature. The heating/cooling treatment ducted by water source of geothermal water is con- heat pump technology. The technological process of the system is introduced. The utilization technology of the residual cooling from air conditioning return water is put forward to achieve the design of large temperature difference and small flow rate in the transmission and distribution system. The energy consumption the transmission and distribution system is reduced, the evaporator inlet temperature is increased, and the operation efficiency of water source heat pump unit is improved.
