Features of Water Cooled Screw Chiller

»The chiller adopts a semi-closed screw compressor. The compressor is with capacity control 0-25%-50%-75%-100%,which is automatically adjusted according to load changes and is more energy efficient.

»Water Cooled screw chiller uses high-efficiency shell and tube heat exchange to improve cooling efficiency. At the same time, in order to reduce the amount of lubricating oil entering the heat exchanger, the chiller increases the secondary oil content to minimize the amount of oil entering the heat exchanger and passes it through a specially designed injector. The oil return device guides the lubricating oil in the heat exchanger back to the compressor, improving the refrigeration efficiency of the unit and improving the reliability of the unit's operation.

»Water cooled screw chiller uses PLC temperature controller to monitor the overall operation of the unit. Its touch screen allows for adjustments and settings. Save energy consumption by regulating the temperature and pressure of the refrigerant entering the compressor.

»By a  water pump, a continuous stream of chilled water enters the chiller from the water tank. The water tank and cooling components of the water-cooled screw chiller are connected through water pipes.

»The Refrigerant Can be R22, R134A, R407C, R404a

How I can Choose the Right Water Cooled Screw Chiller?

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

5.1 Calculate Right Cooling Capacity For Chiller

One of the most frequently ask about how we can know the cooling capacity for chillers.  We use KW ,Ton, But/h,Kcal/h to choose chiller cooling capacity :1 KW=860 kcal/h ;  1 TON=3.517 KW;  1 KW=3412 Btu/h;

There is also a formula to calculate the cooling capacity for chiller:.

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 10m³ water from 35°c to 15 °c in 1 hour?

Temperature Differential = 35℃-15℃=20℃

Water Flow Rate = 10 m³/hour

Cooling Capacity in KW = 10 x 20 ÷ 0.86 = 232 KW

Oversize the chiller = 232 x 1.2 = 278.4KW

278.4 kw cooling capacity for chiller is required.

5.2 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

5.3 Refrigerant

R22, 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.

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℃.

5.4 Evaporator Choose

Air cooled screw chiller generally uses one evaporators: just is shell and tube heat exchanger.Shell and tube type evaporator, which requires an additional water buffer tank to connect.

5.5 Buffer Water Tank Capacity Choose

Buffer tank’s capacity can be customized according to specific needs. It can buffer a larger heat load, store more chilled water .

How Choose Right Water Cooling Tower For Your Water  Cooled Screw Chiller?

Water cooled chiller need connect with water cooling tower and water cooling pump outside for heat dissipation,so how to choose right water cooling tower model to your water cooled screw chiller ?

There are three important temperature factors you need to consider when choosing a cooling tower for water cooled chiller: inlet hot water temperature, outlet cold water temperature, and wet bulb temperature. The hot water temperature is that which enters the tower. The cold water temperature is that which leaves the water while the wet bulb temperature refers to the prevailing temperature of the geographic region where the tower is located.

Approach is the term used to refer to the difference between the temperatures of the water source as it enters the tower versus the temperature of the water once it has left the tower. This is a crucial determiner of the effective of the heat exchange process.

To choose the right cooling tower, mechanical efficiency should be given priority. This refers to the amount of fan power needed to circulate ambient air within the cooling tower. The range – or the difference in temperature between hot and cold water – is also crucial as it will impact energy usage.

so to find out how to choose a cooling water tower with sufficient cooling capacity, you should understand what circumstances require the use of a cooling tower. Please find the below water cooling tower is suitable for water cooled screw chiller :

What is the Difference Between Air Cooled Screw Chiller and an Water Cooled Screw Chiller

Air-cooled and water-cooled screw chillers are both types of chillers used for cooling applications in various industries.

The main difference between air cooled screw chiller and water cooled screw chiller is condenser :

The condenser of an Air-Cooled Screw Chiller is cooled by the ambient air,which the heat generated during the cooling process is dissipated into the surrounding air;

Water Cooled Screw 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 Water cooled screw 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 air cooled screw chiller ,as air cooled screw chiller may consume more energy to achieve the same cooling capacity due to the limitations of air as a heat exchange medium and water cooled screw chiller uses constant water source for more stable and efficient heat dissipation,so in high ambient temperature , water cooled screw chiller is more energy-efficient and better choice for your application .
