Falling Film Evaporator Type Water Cooled Screw Chiller
Products Features
A dry evaporator refrigerant passes through a heat exchange tube and cold water runs outside of the efficient heat exchange tube. Such design is characterized by easy oil return and simple control. The filling amount of refrigerant is about 1/2-1/3 of the capacity of a flooded unit.
A. Optimized Design
Design fully complies with internationalstandards and bases on the actual conditions in China.
The system adopts an independent modulardesign,ensuing high reliability.
The technical thought of large temperature difference and small flow helps the user save resources to the utmost extent.
The optimized design made with the aid of a computer puts the heat pump in an optimal state under any working condition.
B.High-quality Parts
Imported compressors and refrigerating parts ensure efficient and reliable operation of the heat pump.
Efficient heat exchangers are jointly researched and developed with professional matching manufacturers.
In combination of a dedicated control program for water source heat pumps, a high-quality controller makes the use of the heat pump more convenient and fast in the intelligent and network trends.
C.Easy Operation and Reliable Operation
Is fully controlled via a computer and is provided with a manual operating system.
Perfect computer control and multiple protection ensure safe and reliable operation of the whole unit.
D.Wide Range of Suitability
The unit uses water/ground source temperature is wide: 8-35°C.
Can provide not only air conditioning cold and hot water and but also living hot water and can be used as a heating source to supply heat.
The working mediums used: R22 and R134a.
Apart from underground discharge pipe type,we also provides sewage and seawater types.
Full heat recovery type heat pumps can be provided based on the customer’s requirements.
E.Flexible and Easy Setting of Parameters
Setting more than 80 variable in-built parameters can adjust the working state of the whole heat pump at all times.
Memory protection in the case of power failure ensures the continuity of the operating state.
