—— Product Description ——

Withair® heavy capacity Ground (Water) Source Heat Pump is the mature products which are equipped with newly-developed semi-hermetic screw compressors and use dry type or flooded type evaporator, which result in lower noise and lower vibration, reliable long period operation, and installation feasibility on any floor of the building.The units are composed of a compressor(s), a condenser(s),a direct-expansion water cooler, a electronic expansion valve(s),and auxiliary and control equipment.Optimized system design and enhanced heat exchange efficiency makes the unit working best under both full load and partial load. Every unit is fully factory tested and gas charged in the factory before dispatch. It’ s good choice for hotel, shopping mall, hospital, factory, cinema and other civil architecture air conditioning system. Stepless capacities can be customized.The units can be operated with the utmost simplicity.

—— The key advantages Include —— 

● Using for advanced semi-enclosed screw type compressor

The international advanced double-screw semi-enclosed compressor, through slide valve achieve mmultiple-stage or sectionless of adjustment,to adapt to changes in load of smooth and compressor built-in efficient oil separator, the rate can reach 99.7%,using differential injection,no pump, oil, safe and reliable guarantee mechanism for the safe and stable operation, long service life.

● Energy-saving

*  Unit adopts PLC control technology, according to user load demand changes through intelligent control, multilevel energy regulation in full or part of the unit that can reach the best energy efficiency, reduce the operating cost.

* Provide multilevel (0-25% to 50% &75% - 100%) and the energy level adjustment methods for your choice.

● Intellectualized control, simple operation

* Unit adopts PLC control technology, "a key start" and automatic operation.

* In the man-machine interface screen English display, touch screen/LCD text interface for your option.

* Units with remote control functions: turbine control system with built-in WEB browser,users can pass on any computer through internet in the remote monitoring and control unit can operation conditions and parameters of the work unit, the query of the unit.

● Protection function origin

* Units provided the refrigeration system, electrical system and the water system of the complete protection function, ensure its safe operation.

* Unit Settings: unit of power of inverse phase), (high/low refrigeration system protection, oil is too low to high temperature, vent protection system to protect and water flow protection, antifreeze protection safety protection function, guarantee the safe and stable operation of the mechanism.

● Heat recovery function

* Units can be based on user needs, increase the heat recovery function, at the same time in refrigeration heat side will recycle waste heat utilization,and use side and heat side, improved the two-way unit running condition, improve the efficiency of the unit, the unit greatly reduce the operation cost.

* Partial heat recovery and total heat recovery.

● Advanced design, superior performance of high-efficiency heat exchanger

* Shell and tube evaporator within the evaporator using the latest threaded efficient heat exchange tube and tube with high heat efficiency,combined with poor casing baffle slabs of chilled water flow and circuitous increased turbulence effect, make the evaporator heat transfer coefficient has been greatly improved,and the latest flame retardant, use shell heat preservation material, energy loss and ensure the good performance of refrigeration unit.
