Groundwater source heat pump unit
With the development of modern technology, energy conservation and emission reduction have become the focus of global attention, especially the Copenhagen Climate Summit, which has focused the world's attention on environmental issues. Similarly, in the field of construction, as an energy-saving water source heat pump, due to its unique advantages, it has been widely applied and promoted。
In areas with abundant groundwater resources, groundwater contains a large amount of energy, and the temperature changes of this energy are not affected by external environmental temperature, maintaining a constant temperature throughout the year. Therefore, as a high-quality low-temperature heat source, groundwater based heat pump units can fully play a positive role. Based on long-term research and exploration of groundwater source heat pump systems, Worsley specially designed and manufactured screw compressors for the operating conditions of water source heat pump units, and took multiple measures to make them well suited for the usage conditions of water source heat pumps. Application in this series of unitsR134aThe refrigerant unit can achieve65High temperature effluent with high temperature, suitable for special project applications. The application technology of heat exchange tubes to enhance heat transfer performance is to ensure that the system is in a high state of operation*Guarantee of rate. This series of units can meet the requirements of a single machine1000~50000The demand for summer cooling, winter heating, and year-round hot water production for various buildings of square meters.
The main features of this series of products are as follows:
Ø Reliable and energy-saving:Unique combination of energy control systemPLCBy controlling and fully utilizing the shallow geothermal resources (renewable energy) on the Earth's surface as cold and heat sources, coupled with heat exchange tubes with special wing structures, the energy efficiency of the unit is well demonstrated.
Ø Unique designUnique evaporator design, high heat transfer efficiency, low refrigerant charging, and easy oil return.
Ø Stable and reliable:Double screw semi closed compressor only4A moving component, in which the motor and rotor are directly driven, without a speed increasing gear, and the speed is low. Cooling the motor through the return air of the compressor ensures a long service life of the motor.
Ø Environmentally friendly and low-carbon:Fully utilizing natural resources, achieving energy recovery and utilization, reducing equipment investment, and complying with national energy conservation and emission reduction policies. The use of geothermal energy or shallow geothermal resources has a relatively stable temperature throughout the year, which is reduced compared to conventional systems40%The energy consumption.
Ø Reliable and stable:Effective implementation of high pressure, low pressure, oil pressure, water flow protection, oil pressure difference, antifreeze, compressor overload, power reverse phase protection, etc., ensures that the system operates within an effective and reliable range.
Ø Easy to operate:Intelligent design, large screen LCD touch screen display, real-time monitoring of operating parameters, convenient management.
Ø Easy installation:The whole machine has been shipped from the factory, filled with refrigerant and debugged. Just connect the inlet and outlet pipes and power supply on site.
