What Are The Main Components Of 8 Ton 30KW Recirculating Water Chiller

4.1 Compressor

The compressor is the key mover in recirculating Water Cooled Chiller because it produces pressure variations to stir the refrigerant around.

For 8 Ton 30KW Recirculating Water Chiller , which is with TWO units 5HP Panasonic brand compressor, using R410A/R407C refrigerant,this brand compress is with high refrigeration efficiency,low noise ,energy saving,environmental protection and durability,safety and stability.

4.2 Evaporator

The evaporator is a crucial component of recirculating water chiller, as it is responsible for extracting heat from the liquid being cooled,it is located between the compressor and the expansion valve. There are three types of evaporators : coil in water tank evaporator , shell and tube evaporator, 304SS stainless steel plate type evaporator.

Shell and Tube Evaporator

4.3 Water Pump

The water pump is designed to increase the pressure and the flow of the chilled water in a closed space.

the water pressure water pump for chiller is about 2 bar , but if you need more higher water pressure , please tell us when you inquiry .For example ,when you use chillers for cooling bottle blowing machine ,the water pressure for water pump need about 4 bar .

4.4 Condenser

The condenser for recirculating chiller is shell and tube ,with the internal copper tubes employing an outer thread embossing process.This design effectively enhances the heat exchange efficiency between the refrigerant and water during the process. Compared to traditional smooth copper tubes, the outer thread embossing process increases the surface area of the copper tubes, thereby expanding the contact area for heat exchange and improving the thermal conductivity of the condenser. This optimization design allows the condenser of the water-cooled chiller to transfer heat from the refrigerant to the water more rapidly and consistently, enabling the water to carry away the heat.

4.5 Controller Panel

Tongwei chillers use precision digital temperature controller, it RS485 communication port，which can do remote monitoring and control. Simple operation, low failure rate, high safety factor, easy installation.

How I Can Choose The Right 8 Ton 30KW Recirculating Water Chiller?

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

6.1 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.

6.2 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

6.3 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.

6.4 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℃.

6.5 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.

Shell and tube type evaporator, which requires an additional water buffer tank to connect .

How Choose Right Water Cooling Tower For Your Recirculating Water Chiller?

Recirculating Water 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 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 :

Shipping Way of 8 Ton 30KW Recirculating Water 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 .
