Proven Technology

High-efficiency Compressor

The high-efficiency semi-hermetic twin-screw compressor,which is specially designed for the R134a refrigerant,canrealize stepless regulation for energy through its slide valve.The energy regulation range of a single-compressor unit is from 2 5 % to 1 0 0 % ,and regulation range of adual-compressorunit is from 1 2 . 5 % to 100 % ,which can well avoid the problems faced by ordinary units such as frequent start and stop,large fluctuations in water temperature and especially,excessive temperature and humidity control in technological places,thus minimizing the operation cost.

Two-stage High-efficiency Oil Separator + Unique Oil Return Technology

The external level-2 oil separator,which is a high-efficiency horizontal oil separator of independent researchand development,hasa built-in high-strength stainless steel filterscreen.Through collision,filteringand gravity,the oil separatorcanrealize an oil separation efficiency of over 9 9 . 9 % ,which greatly reduces oil residual in the heat exchanger and increases the operating efficiency of the entire unit.

The patented continuous oil return technology of TlCA -oil injected by oil - ensures the safety of oil supply for the compressoras it can take the residual 0 . 1 % refrigeration oil in the evaporator back to the compressor without increasing the power consumption of the compressor.

High-efficiency Heat Exchanger

As for the high-efficiency flooded heat exchanger,the complex tooth-type structure on the external surface of the heat exchange tube facilitates nuclear boiling, thus largely improving the heat transmission outside of the tube; The spiral tooth-type structure on the internal surface helps increase the disturbance of refrigerating medium when it is flowing in the tube,which greatly increases the heat exchange efficiency in the tube.

Advanced Refrigerant Cooling Inverter

With the advanced refrigerant cooling inverter, the unit inverter ismore compact and dissipates heat better.This can take away 9 0 % heat generated by the inverterwhile in operation,cool and make the electrical components live longer,andallow the inverter to operate without compromised capacity even at very high temperatures.

Economizer Circulation

Each unit of the TASF series is designed with an economizer,which dramatically improves the performance and reliabilityof the unit.This signifcantly increases the compressor efficiency and reduces the discharge temperature of the compressor, as well as dramatically improves the cooling and heating performance and reliability of the unit.

Low-noise Fan

Theunit,whichadoptsa largeairflowand low-noise innerrotoraxial flow fan of a well-known brand and is equipped with a long air duct forair diversion,can effectively reduce the noise caused by airflow. Before delivery, the fan has undergone strict tests on static and dynamic equilibrium to ensure stableand low-noise operation.

Electronic Expansion Valve

The unit is equipped with an electronic expansion valve that has a high control accuracyand fast response.Under full load and partial load,the electronic expansion valve can always have an excellent performance that helps greatly increase the energy conservation performance and stability of the unit as well as lower the operation cost.

Features

Energy-efficient

High IPLV

High PowerFactor

The integrated part load value (IPLV)of the unit can reach 4.93.Compared with conventionalaircooled screw units，energy efficiency is increased by 20 % ，highenergyefficiencywill helpyou to significantly shorten the project payback period.

Foraconventional air-cooled screwunit,its power factor is low,whichevendecreasesas theunit load decreases.For the TASFV unit, its power factor can reach up to 0.95 while operating at full load.Therefore, the unit consumes less electricityandresolvestheproblemofpowerfactor decreasingwith thedecreaseof load.

Comfortable and LowNoise

The unit adopts the variable frequency start mode.This allows the unit starting current to increase slowly with the loading process, with maximum current not greater than its rated current, resulting in "zero" impact on the power grid. It makes the power grid safer and more reliable,and reduces impact on the power grid and has lower requirement for capacityof the transformer.

The compressor feet are equipped with rubber shock pads which cannot only reduce unit vibration transmission but also can significantly decrease unit noise;

A noise enclosure and spring shock absorber are also optional for theunitto further reduce noise.
