Fin Type Heat Exchanger
Itadopts the hydrophilicaluminum foil to reduce theadhesionof water on thealuminum foil and greatly improve the heat exchange efficiency. Thealuminum finsare packed in the copper tubeand featuresuniform wind speed.With reasonable arrangement of copper pipes,it is installed in "V"-shape to improve heat exchange eficiencyand reduce fan noise. The copper tubeand aluminum finare mechanically connected through expansionwhich is high performanceand stable heat exchange. It is independently designed and manufactured with strict quality control. Configuringaccording to the place of useand process,it ensures that theheattransfercoeficientmeetsthedesignrequirements.
Compressor
Theunitadopts famous brand compressorwith center bearingcap toachieve highenergyefficiencyand lowsound level.Theunitruns quieterandmoreefficient,withthescrolldesignof "contact-freeand wear-free",itcanreduce friction.
ShellandTube HeatExchanger
Thecoppertube of theevaporatoradopts 1 . 1 \mathsf {mm } thick copper heatexchange tube,which ensures thatall productsmeet the high requirementsof high eficiency,energy saving,safety,strong antifouling abilityanddurability.Accordingto thecustomer'suseconditionsand waterqualityfactors,differentmaterialsof heatexchange tubescan beselected,andthe foulingcoefficientcanbe increasedtoenhance the heat exchange eficiency,ensuring the high efficiency and energy savingand service life of theunit. It is independentlydesigned and manufactured with strict quality control.Configuring according to the placeof useand process,itensures thatthe heat transfer coefficient meets the design requirements.
Fan
With special low-energy fanand reasonable fan nozzle design,it can maximize the airmobilityand reduce the noise.Practice has proven that our fans run stably and have long service life.The waterproof and dustproof grade of themotor: IP54, insulation grade:F;every fan hasa separate split cavity.
Controller
Thecontrolleradoptsthehighlyintegratedbutton-type human-machine interfacecontrol center,which greatlyimprovestheanti-interference ability of the system.The product adopts plastic shell which is easy to install.The front and rear panels exchange data through 485 communication,andtheentiresystemcanbeintegratedorseparated. SiemensPLC controllercanalso beselected to realize ModBus RTU, TCP or S7 communication.

ChinaMachinery IndustryScienceandTechnologyAward
H.Stars Group is the first manufacturer to use heat recovery technology.Patent No.:ZL03223588.7,and has wonthesecondprize of scienceand technologybythe Ministry of -Building Industry.
Heat recovery technology
Recover the condensate heat from chiller units (usually dischargedto theatmospherebycoolingtower),and make effective use of it.For example:a hotel needs both heating (fordomestic hot water) and cooling in the summer.With theheat recovery system,the heat produced during cooling canbetransferredto thebuildingwherehotwaterisneeded through heat recovery. In the summerseason,hot waterabove 5 0 ~ ^ { \circ } \mathsf { C } canbe provided free of charge,and the heat recovery reaches 3 0 % ~ 1 0 0 % of the unit's cooling capacity.
Variable Frequency Drive (VFD) technology
Efficientandenergysaving
Theunit adopts the world-class variable frequency drive technologytogreatlyimprove thepartial loadenergyefficiency of the unit,and the highest comprehensive partial load performance coefficient (IPLV) canreachmore than10.
Moreeco-friendlyandenergysaving
VFD Water Chiller canadopt R134a refrigerant according to the requirements,and won't destroy the ozone of the earth,which complieswith therequirementsof theMontreal Protocol; VFD,flood type evaporator and industrial application energy saving advantages.
VFDadvantage
The VFD Water Chiller has included the soft start function, which can reduce the impact of starting current; the converter is equipped with the DC reactor to reduce the harmonic interference tothe greatest extent; there isalsoa low-harmonic filter option, which meets the IEEE-519 specifications for harmonic distortion attheinputpoweroftheinverter,andhasharmonicfilterovertemperature protection and capacitance switching function.
Note:Customerscanchoosespecialmaterialsandconfigurationsinthe optionsaccording toapplicationneedsto increaseequipmentfunctions, prolong the service lifeandachieve the energy saving purpose.
Simultaneous supply of cold and heat
The unit has the cooling and heating functions simultaneously. It can provide cold for places that need cooling,at the same time absorb the heat during cooling andconvey the heat to places that need heating.Because of the simultaneous cooling and heating,the equipment is ecofriendly and energy saving,and the COP value has been greatly increased.
Industrial IntegratedUnitisthe integrated productdesigned for the industrial field. The unit integrates the chiller,chilled water storage tank,chilledwatercirculatingwater pump,processwater pump,piping,various valves,andengineeringcontrol cabinet. The project is integrated in the production line,with reliable quality,compact structure and high integration.Itis simpleand convenient installation,andcanreduce the project installation costs.
