APPLICATION STUDY ON THREE-STAGE HEAT PUMP SYSTEM WITH GEOTHERMAL WATER

摘要：

Many projects of heat pump systems had been built during last ten years and are still being built recently. Geothermal water is a very good resource for heat pump, and these combined systems can be found in many places in China where geothermal water is rich. Single stage heat pump system only has 10-12 ℃ temperature range for geothermal water, and it is considered one kind of waste of geothermal water. A three-stage heat pump system is showed in this paper and the characteristic like EER is analyzed. According to the site measurement, it can be concluded that three-stage has the approximate EER compared to the single stage heat pump, but its geothermal water resource efficiency is twice as much as the single one.
