BriefIntroductionofAir-CooledChiller
The 20STB Series Air-cooled Chiller isadoptinga combination of famous brand compressors and electronic control components, and isequipped with high-efficiency fin condenserand shell and tubeevaporator.Theunit is controlled bymicrocomputerand equipped with various protection functions,which can accurately control the operating conditionswith high reliability. It is designed forcomfortableairconditioning,suitable forcommercialbuildings such as hotels,shopping malls,office buildings etc.Modular combinationscanbe formedaccordingtocustomerneeds.
Cooling capacity range:25kW-276kW
Fin Type Heat Exchanger
Itadopts thehydrophilic aluminumfoil to reduce the adhesionof water on the aluminum foil and greatly improve the heat exchange efficiency.Thealuminum finsare packedinthecopperand features uniform wind speed.With reasonable array copper pipes, it is installed in "V"-shape to improve heat exchange eficiency and reduce fan noise.The copper tube and aluminum fin are mechanicallyconnectedthrough expansionwith highperformance andstable heat exchange.It is independentlydesignedand manufacturedwithstrict qualitycontrol.Configuringaccording to the placeofuseand process,itensures that the heat transfercoefficient meets thedesignrequirements.
Compressor
The unit adopts famous brand compressor with middle bearing cap toachieve highenergy eficiencyand lowsound level.Theunit runs quieterandmoreeficient,with the scroll designof "contact-freeand wear-free",itcanreduce friction.
Shell and Tube Heat Exchanger
Thecoppertubeof theevaporatoradopts 1 . 1 \mathsf {mm } thick copper heatexchangetube,whichensuresthatall productsmeetthe highrequirementsof high efficiency,energysaving,safety,strong antifouling ability and durability.
According to the customer's use conditionsand water quality factors, different materials of heat exchange tubes can be selected, ensuring the high efficiency and energy saving and service life of the unit. It is independently designed and manufactured with strict quality control.Configuringaccording to the place of useand process, itensures thatthe heattransfercoefficientmeetsthedesign requirements.
Fan
Itadoptsspecial lowenergyconsumptionmotorpatented fannozzle toimprove theairmobilityandreduce thenoise.Motorwaterproof and dustproof grade: IP54,insulation grade:F.
Controller
The controller adopts the highly integrated button-type humanmachine interfacecontrol center,which greatly improvestheantiinterferenceability of the system.
The product adopts plastic shell,which is easy to install.
The front and rear panels exchange data through 485 communication,and the entire system can be integrated or separated.
SiemensPLCcontrollercanalsobeselectedtorealizeModBus RTU,TCP or S7 communication.

Heat Recovery Technology
Functioncharacteristics
Recover the condensate heat from chiller units (usually dischargedto theatmosphere bycooling tower),and make effective use of it.For example:a hotel needs both heating (fordomestic hotwater) and cooling in the summer.With the heat recovery cycle,the heat absorbed during cooling canbetransferredtothebuildingwherehotwaterisneeded through heat recovery.In the coolingseason,hotwater above 5 0 ^ { \circ } \mathsf { C } can be provided free of charge,and the heat recoveryreaches 3 0 % ~ 1 0 0 % of the unit's cooling capacity. H.Stars Group is the first manufacturer to develop heat recoverytechnology.Patent No.:ZL03223588.7,and has won the prize of scienceand technology by the Ministry of -Building Industry.
VFDTechnology
Highefficientandenergysaving
The unit adopts the world-class brand variable frequency drive technology to greatly improve the partial load energy efficiencyoftheunit,andthehighestcomprehensivepartial load performance coefficient (IPLV) can reach more than 10.
More eco-friendlyand energysaving
VFDwater chiller can adopt R134a refrigerant according to therequirements,andwon'tdestroythe ozone layerof the earth,which complieswith the requirementsof the Montreal Protocol;VFD energy saving,flooded type evaporator energy saving,industrial application energy saving advantages.
VFDadvantage
The VFD water chiller has the soft start function,which canreduce the impact of startingcurrent;the converter isequipped with the DC reactor to reduce the harmonic interference to the greatest extent; there isalsoa lowharmonic filter option，which meets the IEEE-519 specifications for harmonic distortion at the input power of the inverter,and has harmonic filterover-temperature protection and capacitance switching function.
