- product introduction:① High energy saving
Adopt a new generation of semi-closed twin screw compressor, compact structure, mature technology, high compression efficiency, energy saving up to 10%, stable operation, combined with matching optimization of refrigeration system and reliable control technology to ensure efficient operation of the unit; Adopt new efficient heat transfer tube, high heat transfer efficiency; The electronic expansion valve with the adjustment grade of 3810 is precise and sensitive, accurately adjusting the condensing pressure, higher refrigeration efficiency, dynamic control of the evaporation outlet refrigerant superheat, and higher utilization efficiency of the heat exchange area; Advanced economic cycle design, greatly improve the unit refrigeration capacity and further improve the unit refrigeration efficiency; Multi-loop, multi-compressor design, low starting current, high partial load efficiency and good standby function; Intelligent defrosting control logic is used to optimize the defrosting cycle entry time, which avoids unnecessary heat loss and improves the stability of hot water outlet temperature, and has excellent heating performance.
② Quiet operation
Adopt semi-closed screw compressor, direct motor drive, low compressor speed, stable compression process; The shape size of the "" fin heat exchanger is optimized to make the air passing over the surface of the coil more uniform and quiet; Low noise axial fans operate more quietly.
③ Environmental leadership
The unit directly extracts heat from the air, without boiler, cooling tower, consumption of a small amount of electricity, can achieve heating and cooling, to maximize the saving of one-time energy, the unit does not need any emissions and pollution, green low-carbon environmental protection; The use of environmental leading refrigerant C-134a, no chlorine, no damage to the atmospheric ozone layer, no ban period, excellent refrigeration performance, save energy consumption, reduce COz emissions, global warming potential is small; Advanced "leak-free" refrigeration circuit design, refrigeration pipe welded connection, abandon the traditional capillary design, replace with electronic expansion valve and electronic temperature/pressure sensor, fundamentally eliminate a variety of potential leakage.
④ Convenient installation
The unit adopts modular structure design, which can be produced and transported with standard module units and combined into a complete unit at the installation site. The standard module units are light in weight and small in size, which can save a lot of costs in the process of transportation and hoisting. The clamp type water pipe connection is convenient and reliable, which not only reduces the installation difficulty but also effectively blocks the vibration transmission. The unit has been installed sensitive and maintenance-free electronic flow switch, complete the relevant wiring, save the site installation time; The quick self-test function allows the unit to progressively check electrical components and components such as electronic expansion valves, fan motors, and compressors before operation.
⑤ Reliable quality
Compressor, refrigeration system accessories and electronic control components used in the unit are from well-known brands at home and abroad, accurate control, reliable performance; The use of semi-closed screw compressor, high-grade bearing selection, no oil pump lubricating oil road design, all components can be on-site maintenance, compressor operation is extremely safe and reliable; The adaptive control logic effectively avoids the over-frequency start and stop of the compressor. When the condensing pressure rises abnormally, the compressor is automatically unloaded. When an accident occurs, the unit automatically adjusts the cooling capacity and continues to operate reliably. The unit has cold water outlet low temperature, high and low pressure protection, exhaust high temperature protection, oil level protection, oil pressure difference protection, motor protection, voltage protection, flow protection and so on.
⑥ Friendly human-machine interface
A new generation of LCD touch screen control display, menu management, unit operation parameters at a glance, simple and convenient operation, and can switch English display operation; Through the control interface menu, you can quickly obtain the operating parameters such as inlet/outlet temperature, inlet air temperature, current water temperature control point, evaporation/condensation temperature and pressure of each refrigeration loop, and operation time of each compressor. Provide local, remote control (on-line) and network three operation control modes; Automatically monitor all control and safety parameters of the unit in real time during operation, alarm if necessary, and provide common troubleshooting methods; The control system is equipped with RS485 standard serial communication interface, which is used for remote or special diagnostic tool analysis and judgment. Provides password protection to prevent incorrect operations.
⑦25 years of producting history, for OEM/ODM products.
