How I can Choose the Right Air Cooled Screw Chiller?

There are five 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 .

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 screw 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 .

Water Cooled Screw Chiller

Industrial Applications of Air Cooled Screw Chiller

Air-cooled screw chillers are very popular refrigeration system that can provide steady and reliable water cooling sources for both industrial and commercial usage.

Air cooled screw chillers are also widely used in plastic industry,food industry ,chemical industry and Cement/ Concrete Cooling.

8.1 Plastic Industry

Air-cooled screw chillers are also widely used in plastic processing and plastic industry including plastic injection molding, plastic extrude, and extrusion lines, blowing molding machines.

The function of using an air-cooled screw chiller is to provide the cooling water flow rate for cooling the plastic mold temperature down to make sure the product quality and production efficiency.

8.2 Food and Beverage Industry

Air cooled screw chillers are an efficient way to cool your products without freezing in the manufacturing vessel. Some examples such as wine fermentation, beer/brewery chiller, carbonated water chillers, and dairy processes have all been enhanced with the use of water-cooled scroll chiller. The water is chilled in the chillers and then flows through closed loop tubes attached to the heat exchanger food and beverage containers. This prevents metal corrosion often found in water and also keeps your product at a consistent temperature. Whether you need the best yeast to keep your wine fermenting or prevent your milk from going rancid, a screw chiller can help you achieve your ideal results.

8.4 Cement /Concrete Cooling

Cement production involves a series of chemical reactions that generate significant amounts of heat.Cement is usually mixed with water to from the material known as concrete whose temperature is to a great extent determined by the water used in the chemical combination of cement aggregates and water.

Shipping Way of 60 Ton Screw Compressor Chiller

As a professional water chiller supplier &exporter,we have our own shipment forwarder to arrange the shipment .Our chiller machine is with plywood packing,which prevent damage during transportation and meet export standards.There are three ways can delivery your chiller unit :

1. Ship by Air: As the chiller is with compressor ,water pump and fans ,the compressed refrigerant and oil inside the compressor is a dangerous item with the possibility of explosion , so it needs to release the compressed refrigerant before transportation. (It means that water chiller without refrigerant when choosing this shipping way. After the machine arrives at your destination, you need to add refrigerant by local professionals. The airline company also request us to provide many documents to prove that the chiller not a dangerous product. The freight cost by air is very high may be higher than the cost of chiller , So By air for delivery is not the mode of transport recommended to our customer.

2. Ship by Sea: The transportation time is longer than by air , but the freight cost is cheap ,and there is no need to add refrigerant after the equipment arrives at the destination.This shipping way is the most suitable mode of transportation for you to delivery your local port.

3.If you have your own shipment container in your other supplier in China, we can help you delivery the chiller machine to your supplier in any city of China .
