    3.What is the Difference Between Industrial Air Cooled Chiller and Industrial Water Cooled Chiller?

    Industrial Air-cooled and industrial water-cooled chillers are both types of chillers used for cooling applications in various industries.
    The main difference between industrial air cooled chiller and industrial water cooled  chiller is condenser :
    The condenser of an industrial air cooled chiller is cooled by the ambient air,which the heat generated during the cooling process is dissipated into the surrounding air;

    Industrial Water Cooled Chiller with a shell and tube water-type condenser that is attached to a cooling tower and is typically used in medium and wide installations where water is available.So industrial Water cooled chiller need connect with water cooling tower and water cooling pump outside , the installation is more trouble than air cooled screw chiller .
    But if your ambient temperature is very high above 50℃,we suggest you use industrial water cooledchiller ,as industrial air cooled chiller may consume more energy to achieve the same cooling capacity due to the limitations of air as a heat exchange medium and industrial water cooled chiller uses constant water source for more stable and efficient heat dissipation,so in high ambient temperature , industrial water cooled chiller is more energy-efficient and better choice for your application .

    4.How I Can Choose The Right Industrial Chiller System?

    There are four important chiller specifications you need consider when you choose a chiller for your application :the voltage required for operation, the associated pump horsepower and flow rate (contact us for custom selection), refrigerant, and the evaporator type.

    4.1 Power

    Different countries and regions have different standards for industrial electricity, the common power supplies are 208-230V, 380-420V,440-480V,50Hz or 60Hz, 3phase.

    Such in Philippines ,the power supply is 220V 60HZ 3PH , 380V 60HZ 3PH ,460V 60HZ 3PH;

    in Singapore and Malaysia ,the power supply is 415V 50HZ 3PH;

    in Mexico ,the power supply is 220V 60HZ 3PH;

    In USA ,the power supply is 208V 60HZ 3PH;575V 60HZ 3PH;480V 60HZ 3PH and so on

    4.2 Water Pump

    When you decide the capacity/tonnage of the chiller, we will recommend you the suitable pump in KW,which standard water pump is about 2 bar .If you need more high water pressure , please us when you inquiry.

    4.3 Refrigerant

    R22, R410A, R407C, R404A, R134A are optional choices.

    R22: good cooling effect, but R22 is considered a powerful greenhouse gas, so it’s forbidden in most countries.

    R410A: eco-friendly, R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan, Europe, and the United States. R-410A operates at higher pressures than other refrigerants.

    R407C: a good replacement for R22, good cooling effect.

    R404A: suitable for application that requires low temperature(below -10°c).

    R134A: a non-flammable gas used primarily as a “high-temperature” refrigerant, suitable for air-cooled chiller working at a high ambient temperature above 50℃.


    4.4 Evaporator Choose

    Chillers generally have two types of evaporators: one is coil in water tank evaporator ,the other one is shell and tube evaporator.

    Coil and tank evaporator, which has a built-in water storage tank for more convenient use,so there’s no need for extra buffer tanks. This is also our standard evaporator for chiller , if you don’t have buffer tank ,we just use this evaporator for your chiller.(See Above 2.2)

    Shell and tube type evaporator, which requires an additional water buffer tank to connect .(See Above 2.2)

    5.Industrial Applications of Industrial Chiller System

    Industrial chiller unit is very popular water cooling system that can provide steady and reliable water cooling sources for both industrial and commercial usage.
    Industrial chiller unit is also widely used in plastic industry and food industry .

    1 . Testing results under above conditions: Inlet/outlet chilled water temperature 12℃/7℃, condensing temperature 45℃.

    2. The above parameters will be updated continuously. If you have special request, please send your technical requirements before placing an order.
    1.How does a chiller system work?
    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 right cooling capacity for chillers?
    One of the most frequently ask about how we can know the cooling capacity for chillers. Let’s see the below formula.
    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)
    Oversize the chiller by 20% Ideal Size in KW = KW x 1.2
    Noted : T1:Incoming Water Temperature (℃)      T2:Required Chilled Water Temperature(℃)    
        
    For example, what size of chiller is required to cool 5m³ water from 25°c to 15 °c in 1 hour?
    Temperature Differential = 25℃-15℃=10℃
    Water Flow Rate = 5 m³/hour
    Cooling Capacity in KW = 5 x 10 ÷ 0.86 = 58,14 KW
    Oversize the chiller = 58.14 x 1.2 = 69.76 KW
    69.96kw cooling capacity for chiller is required.

    3.Types of chiller system?
    There are two types of chiller :Air Cooled Chiller and Water Cooled Chiller.
    Water cooled chiller needs a separated water cooling tower and water cooling pump ,if you don‘t have exsiting water cooling tower,we suggest you use air cooled chiller; But if your ambiemt temperature is very high above 55℃ ,we suggest you use water cooled chiller , as it is easier to dissipate heat for water cooled chiller with water cooling tower.

    4.Whether chillers need built-in Tank or not?
    In a chiller system, a tank is usually equipped to buffer the thermal load of the chiller.
    But should we choose a built-in type of tank or an external type of tank?
    A chiller with a built-in tank is easier to install and can be used simply by connecting a water pipe to your application. 
    But it has a limited capacity and is not suitable for applications with larger chilled water demands.External tank’s capacity can be customized according to specific needs. 
    It can buffer a larger heat load, store more chilled water, but the installation will be more troublesome.
    If you don‘t have external water tank ,we suggest our chiller built-with water tank ,which is easy for you to install.

    5.Cooling capacity unit conversion?

       1 KW=860 kcal/h ; 

       1 TON=3.517 KW; 

       1 KW=3412 Btu/h;

    6.This chiller could do heat recovery?
    Yes,please kindly send us the temp and water volume per hour.

    7.Chiller maintenance?
    Step 1: Keep Tubes Clean
    Step 2: Ensure a Leak-free Unit
    Step 3: Sustain Proper Water Treatment(prevent scale, corrosion)
    Step 4: Analyze Oil and Refrigeran
    Please submit your basic information, we will contact you as soon as possible!
