1.What is Stationary Chiller ?

Stationary chiller refers to any chiller that does not include a pump or tank. The main component is a self-contained chiller that must be piped to a pump and a separate reservoir to function. The system usually has separate controls for the chiller and pump or pumps, with electrical connections for each component. Ideally the controls should be wired together to prevent the chiller from cooling down until the circulation pump is running.

We offer stationary chillers including sizes cooling capacity ranging from 10 ton to 200 ton are available in stationary air-cooled chiller and stationary water-cooled chiller.

2.Stationary Air Cooled Chillers Vs Stationary Water Cooled Chillers

▪ Air cooled chillers require less maintenance than water-cooled units.

▪ Air cooled chillers do not require a water cooling tower or a condenser water cooling pump.

▪ Consume approximately 10% more power than a water-cooled unit due to wet surfaces transferring heat better
than dry surfaces.

▪ Air-cooled chillers require less water.

Air-cooled chiller systems are widely used in places where water resources are not sufficient or water quality is not very good. The most convenient part is that air-cooled chiller systems do not require cooling towers, so they are easy to install. (If an air-cooled chiller isn’t what you need, please refer to water-cooled chiller.)

4.What are Differences Between Stationary Chiller and Portable Chiller ?

The main difference between stationary chiller and portable chiller is that :

Stationary chiller does not include a pump or tank inside , which need buffer water tank and water pump outside;
Portable chiller combines all necessary components including – the refrigeration circuit, full diagnostic touch screen controllers and electrics, process pump ,a reservoir tank,which is easily to install.

5.What Are The Main Components of Stationary Air Cooled Chiller?

5.1 Compressor

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

For 120 Ton chiller , which is with 2 units Hanbell Screw brand or Bizter Screw compressor for optional depends on the required refrigeration capacity, using R407C refrigerant,this brand compress is with high refrigeration efficiency,low noise ,energy saving,environmental protection and durability,safety and stability.

Each screw compressor with 4 steps of energy control 25%-50%-75%-100% to make sure the whole screw chiller is stable and guarantee high refrigeration performance.

5.2 Evaporator

The evaporator is a crucial component of stationary air cooled chiller, as it is responsible for extracting heat from the liquid being cooled,it is located between the compressor and the expansion valve. Stationary Air Cooled Chiller Uses highly efficient closed loop shell and tube type heat exchanger as the evaporator.

5.3 Condenser

The condenser for air cooled screw chiller is equipped with efficient cross-seam fins and female threaded copper tubes for high heat exchange efficiency and good stability.Its function is to cool down the refrigerant steam released from the compressor into a liquid or gas-liquid mixture.

6. How I can Choose the Right Stationary 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.

6.1 Calculate Right Cooling Capacity For Chiller
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.

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, 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℃.

6.5 Evaporator Choose

Air cooled screw chiller generally uses one evaporators: just is shell and tube heat exchanger.(See Above 2.2)

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

6.6 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 .

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 Screw Chiller and Water Cooled Screw 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.Cooling capacity unit conversion?

1 KW=860 kcal/h ;

1 TON=3.517 KW;

1 KW=3412 Btu/h;

5.This chiller could do heat recovery?

Yes,please kindly send us the temp and water volume per hour.

6.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
