1.  Water chiller how it works?

      Chiller has two circulation,one is process water circulation,the other is refrigerant gas circulation.Heat picked up from the process.Heat transfers to refrigerant circulation.Heat is remove to air or water.


2.  How to calculate chiller load

     Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-t2)/0.86

     Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)


3.  Types of chiller system?

    Air Cooled Chiller and Water Cooled Chiller.Water cooled chiller needs a separated cooling tower and has a higher efficiency,but less easier than air cooled for installation.


4.  Chiller capacity unit?

1 kcal/h = 1.163W,1 W = 0.8598 kcal/h; 
1 Btu/h = 0.2931W,1 W = 3.412 Btu/h; 
1 USRT  = 3.517 kW,1 kW = 0.28434 USRT;  
1 kcal/h = 3.968 Btu/h,1 Btu/h = 0.252 kcal/h; 
1 USRT = 3024 kcal/h,10000 kcal/h = 3.3069 USRT; 

5. Which compressor brand you adopt?

     Panasonic,Danfoss,Copeland,Invotech,Hanbell,Fusheng,Bitzer and Refcomp.

6. What is the lowest temp outlet you made?

    -45 DegC.

7. What is the material of the evparator you adopt?   

    If salt water,we usually adopt Tiatanium or Alpaka.If glycol,normal shell and tubes evaporator is ok.


8.  Where are the chiller using?

     Water chillers are the major contributors that help cool and condition in the big industrial, commercial as well as the institutional sectors and are used to reduce the temperature of various equipment like computer parts or robotic machinery. Industrial water chillers are used in large capacity applications where heat generated by air cooled chillers create problems. They are also used in water coolers to cool down the drinking water which can as well be added to various drinks and beverages. If you are going to buy one water chiller for yourself then it is always better to know their functioning. This can help you to choose the right one as per your requirement.

In the plastics industry, a chilling system cools the hot plastic that is injected, blown, extruded or stamped. A chilling system can also cool down the equipment that is used to create plastic products (hydraulics of the molding machine, gear box and barrel of the extruder) that saves on energy and on the wear and tear of the machine itself. 

In the printing industry, a chiller not only removes the heat generated by the friction of the printing rollers, but cools down the paper after it comes out of the ink drying ovens in the process. 

In the laser cutting industry, light projection industry, etc. a chilling system is used to cool down the lasers and power supplies. 

In the rubber industry to cool the multizone water temperature control units of the rubber extruder barrel, cool the rubber mill, calendars and bambury mixers. 

In the beverage industry, a chiller removes the heat gained from the process during mixing, cooking, or after pasteurizing the product. 

If you use high tech equipment for magnetic resonance imaging, scanning, blood cooling and laboratory testing, you'll need a cooling system to remove all the heat generated. 

With cooling expenses accounting for 30% to 50% of your total energy costs and rising fast, and the impending phaseout of chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) refrigerants, there is a rapidly growing need to replace large commercial air conditioning and refrigeration systems with a modular chilling system. 


9.  Chiller maintenance?

step1: keep tubes clean

step2: ensure a leak-free unit

step3: sustain propwer water treatment(prevent scale,corrosion)

step4: analyze oil and refrigerant

10.  Chiller Package?

       Wooden case.

11.  Delivery time?       

      Standard chiller model lead time: 15-20 working days

      Customized chiller lead time: 25 - 40 working days
