 This   system uses the Single Well Supply/Return Water Technology as an energy   collection subsystem to collect and use the shallow ground geothermal   energy with low temperature to provide heating, cooling and domestic hot   water (Triple-Supply System) for buildings. This system is HYY (Heng   You Yuan Co.) patent technology which is able to use for various   geological condition and building indoor parameter requirements. The   Single Well Supply/Return Water Technology can perfectly protect   groundwater resource.
 2.The main equipments of HYY system 
The   main equipments of HYY system include ground energy sourced heat pump   (Energy Promotion Device), circulation water pump, water filling and   pressure device, hot water supply device, energy collection device.   Standby equipment: operation data record, transmission, treatment on   line or by radio.
