Difference Between Air Cooled & Water Cooled Chiller:-

Air Cooled

  • In Air Cooled The condensing medium is used- Air
  • Simple construction, Initial cost is high but maintenance cost is low
  • The hot air Can easily Dispose
  • No handling Problem
  • Air Process low thermal conductivity and condenser capacity this system is very low.
  • No corrosion due to Air
  • Do not require sophisticated piping arrangement for carrying the Air
  • Air Cooled condenser used low capacity operation
  • It requires more power for circulation of Air and high power fan are noisy

Water Cooled

  • In water Cooled condensing medium is used- Water
  • Complicated construction, initial cost is low but maintenance cost is High
  •  Problem of disposal used Water (unless there is a recirculation system)
  •  Water cooled condenser are difficult to handle.
  • High thermal conductivity of water favors High heat transfer capacity.
  • Higher Chance of fouling effect. Water causes corrosion of condenser tubes.
  • Piping arrangement is required for carrying cooling water.
  • The water cooled condenser used for large capacity plants.
  • It requires less power to circulation on water.

Air Cooled Water /Glycol chiller

An air-cooled refrigeration system is typically located outdoors and is subject to its surrounding ambient temperatures. In hot summer months, compressor efficiencies are diminished due to sweltering temperatures.

In some cases, air-cooled refrigeration systems are located indoors. If the compressor room is not properly ventilated, hot exhaust from the condenser may re-enter the condenser intake and create a cycle  of perpetual overheating.

This system has several essential components including:
Scroll/ Reciprocating/ Screw Compressor
Condenser (shell & tube type)
Shell & tube/ PHE Evaporator Suitable for application requirement.
Make-up water pumps
SS-304 SASG make reservoir suitable for application requirement.
Electronic/ Thermostatic Expansion valve is available as customer
choice.
Available in Multiple Refrigeration Circuits.

Water Cooled Water /Glycol Chiller

Some users may prefer these chillers because of the smaller size they occupy as compared to air-cooled chillers. These chillers also feature higher efficiency  and last longer than the mentioned alternative. Those who would like the equipment to be placed indoors may find the water-cooled machine desirable.

This system has several essential components including:
Scroll/ Reciprocating/ Screw Compressor
Condenser (shell & tube type)
Shell & tube/ PHE Evaporator Suitable for application requirement.
Make-up water pumps
SS-304 SASG make reservoir suitable for application requirement.
Electronic/ Thermostatic Expansion valve is available as customer

Benefits of chillers Compressor wise

Screw Compressor Benefits
1. Occupy Very Less Space for Installation of Plant
2. Energy Efficiency
3. Emit Very Less noise while Functioning
4. Less Maintenance Works
5. Best Compressor for Long-run

 Scroll Compressor Benefits
1. It enhances the operating efficiency
2. Extended chiller life cycle
3. No chiller downtime
4. Cleaning system operating costs are low
5. The water treatment costs are also low
6. It is environment friendly

Reciprocating Compressor Benefits
1. Compressor is repairable.
2. Easy to operate
3. Using for low temperature
4. Low maintenance cost
5. Fast return on investment

 Variable Speed / Inverter Type Compressor Benefits
1. It enhances the operating efficiency
2. Extended chiller life cycle
3. No chiller downtime
4. Initial cost is high.
5. The water treatment costs are also low
6. It is environment friendly
7. Inbuilt Variable Frequency Devise.
8. Used with Eco Friendly Refrigerant R-410.
9. Electronic Expansion valve is required

Digital Scroll Compressor Benefits
1. It monitors temperature levels, making adjustments to its RPM speed, therefore, it significantly reduces noise. Extended chiller life cycle.
2. It delivers up to 40 percent more energy efficient than conventional compressors.
3. It keeps noise to a minimum level which leads to less power consumption.

Liquid Injection Scroll compressor Benefits
1. In this arrangement, the increase or decrease in pressure at the intermediate stage of the compressor in response to increase or decrease of suction  pressure, and hence the pressure differential across the compressor, acts to automatically regulate the amount of liquid refrigerant injected, thus  providing enough liquid.
2. Use in low temperature applications

Vapor injection Type Scroll Compressor Benefits
1. The Vapor injected scroll compressor makes use of an economizer with the Vapor compression cycle. This cycle offers the advantages of more cooling capacity and a better COP than with a conventional cycle
2. Use for very low temperature application.
3. Economizer is required.
