Frosting of the compressor suction pipe. This may be because of the improper drainage of the system.

It could also mean the blockage of the system pipeline

Condensation pressure is too high. It happens when your refrigerant flows is too much.

This makes the temperature of the outside air too high.

If it is too low. This could mean your chiller’s refrigerant flows is not sufficient.

Also, may mean damage to the compressor of the chiller is damaged.

Excessive heat pressure and excessive suction.

This could happen if the expansion valve is not properly adjusted.

Air Cooled Water Chiller

Do Air Cooled Chillers Need Water?

Chiller means a machine for water chilling. So, you must use water.

When we mean air-cooled, we mean the chiller’s cooling type of condenser.

What Could Cause Air Pockets In An Air Cooled Chiller Evaporator?

Four things could cause this.

Leakage of a corrosive high pressure liquid or steam with high temperature

The leakage could happen in the equipment, flange, and pipeline weld.

It could also happen in other weak links like the expansion joint and sealing filler.

It is caused by cracking due to cold contraction and thermal expansion while starting up and shutting down.

This can also happen due to corrosion and stress impact.

Figure 3: Components of a Chiller

The blockage of the pipeline valve

Crystallization happens with increases in material concentration.

This results in the blockage of the heater, valves, pipelines, etc.

When this happens, the materials will not circulate thereby affecting the smooth operation of evaporation.

Cooling Towers

Method of troubleshooting for the evaporator’s high temperature

It could be that the expansion valve opening is too large.

Also, mean that there’s too much refrigerant coming into the evaporator.

This can be caused by a very high condensation temperature.

Due to this, there is an increase in the evaporation temperature.

Figure 4: Air cooled Chillers Condenser

Very low evaporation temperature

This could be caused by three things:

• The expansion valve opening is too small or blockage of the expansion valve.
• There is not enough refrigerant substituting liquid. Due to this, just a little refrigerant enters the evaporator. This causes part of the surface area not to be able to partake in heat exchange.
• The chilled water’s temperature present in the evaporator is either frozen or too low.

Scroll Compressor

screw compressor

What Does Superheat In Air Cooled Chillers Mean?

Superheat in air cooled chillers refers to when there’s poor excess heat dissipation in the condenser.

It could also be that the compressor’s efficiency is low, or an increase in the running current.

When its high-pressure pressure increases to 24kg/cm2, this could happen;

The compressor trips off below the high-pressure switch’s protection, which will halt the running of the compressor.

The high-pressure overload caused as a result of poor excess heat dissipation will reveal the fault indication or fault code.

How Can I Improve An Air Cooled Chiller’s Efficiency?

To improve the efficiency of air-cooled chillers, please follow these:

• Make sure you clean your air-cooled chiller regularly.
• Don’t start and stop the switch button frequently.
• Ensure that there are ventilation and drying in the refrigerator room.
• Don’t stack combustibles or sundries close to your air cooled chillers.
• Check from time to time to ensure the system’s water supply is normal. The system should never experience a water shortage.
• Before you start the air cooled chillers, preheat the compressor. Then you turn on the power supply.
• Clean your chiller’s inner fin heat exchanger regularly. This is to ensure heat exchange.
• Never allow non-professional personnel to dismantle or change the unit. If your water cooled unit has any problem, get a professional to check and solve the problem immediately.
• Ensure that no stacking materials or high walls are in front of the chiller’s exhaust fan. This could cause a blockage of the exhaust passage. The refrigeration effect could be affected as well.
• If you will be shutting down the unit for long, try to drain the pipeline’s water. This is to prevent cracking and freezing due to a drop in temperature.

Why Don’t We Have Air Cooled Chillers Larger Than 500 Ton R?

The capacity at which chillers begin to make sense economically is 500 tons.

If you want an air cooled chillers that produces over 500 tons, then you could do it.

This is because the heat transfer surface limits air cooled chillers.

Air cooled chillers reject excess heat by the ambient air coming in from both sides.

It cools the hot condenser coil which the condenser fans have blown up.

All you need is to install many chillers with many pumps.

At least, this gives you partial capacity in case one of the systems breaks.

How Can I Create An Air Cooled Chiller’s Part Load Performance Table?

It is possible by making use of load banks to stimulate part-load conditions.

Most times, this happens before shipment in the factory when a client requests it.

Air cooled chillers comparison

Air-cooled scroll unit VS air-cooled screw unit

Air cooled chillers performance:

Air-cooled Scroll Chiller Compressor Performance:

Using a fully enclosed scroll compressor, the compressor runs smoothly, with low vibration, low noise and long service life.

Air-cooled Screw Chiller Compressor Performance:

The screw compressor is used. During the high-speed rotation and meshing of the screw, the compressor will produce certain vibration and noise. As the working time increases, due to the increase of the rotor gap, the operation highly efficient decreases and the power consumption increases.

Air-cooled Scroll Chiller Control Performance

Multiple compressors are operated in parallel, and the number of compressors can be automatically adjusted by the programmable microcomputer controller according to the changes in the terminal air-conditioning load. Therefore, the unit is especially suitable for occasions with low load and large load changes, but the operating highly efficient will not change with the load changes, and the energy-saving effect is very obvious. The microcomputer can also automatically record the running time of each compressor to realize the balanced wear function of the compressor.

Multiple compressors operate in parallel and work independently. When individual compressors have operating failures and need to be repaired, they will not interfere with the normal operation of other compressors, so as to ensure that a certain amount of cold and heat sources can be provided in the event of failures.

Air-cooled Screw Chiller Control Performance:

When a single compressor works, the unit adopts stepless capacity adjustment, which will cause the main engine to run at low load, reduce operating efficiency, reduce energy efficiency ratio, and increase operating costs.

When a single compressor is working, even minor failures in the refrigeration chiller system will affect the normal operation of the entire unit and cause the entire air-conditioning host to be in a shutdown state.

Installation comparison:

Air-cooled Scroll Chiller Installation comparison:

The unit adopts a modular design, which brings more convenience to installation and transportation. The number of modules can be freely combined according to the actual situation of the user. On-site hoisting, handling, and splicing are all very freely.

Air-cooled Screw Chiller Installation comparison:

The unit adopts an integral structure, which is heavy and bulky, and it is very inconvenient for transportation, installation and handling.

Maintenance comparison:

Air-cooled Scroll Chiller Maintenance comparison:

Multiple compressors, multiple chiller system, independent design, fewer chiller system components, light weight, and sufficient space for maintenance. Therefore, maintenance and repair are very convenient.

Air-cooled Screw Chiller Maintenance comparison:

Single compressor, single chiller system, large parts, heavy weight, and very heavy, it is difficult to leave enough space for inspection and repair. Once the equipment fails, troubleshooting is very difficult and it takes a long time.

Investment comparison:

Air-cooled Scroll Chiller Investment comparison

The one-time investment is small, and it can be installed in batches; if the cooling capacity needs to be expanded, only the modules need to be added, which is very convenient.

Air-cooled Screw Chiller Investment comparison:

Bigger

Operating cost comparison:

Air-cooled Scroll Chiller Operating cost comparison

The operating efficiency is relatively high under various air-conditioning operating conditions, and the energy efficiency ratio changes little. Therefore, especially for air-conditioned places where the air-conditioning load changes greatly, the energy-saving effect of operation throughout the year is very obvious.

Air-cooled Screw Chiller Operating cost comparison:

When the air-conditioning load changes greatly, the operating efficiency is low and the energy efficiency is relatively small, and the water pump must run continuously. Therefore, the energy-saving effect of the annual operation is very poor. Compared with the air-cooled scroll cold water heat pump unit, the operating cost increases by 15% to 20%.
