You will realize that the evaporators have delivery systems that transport the heat from the MRI into the chillers.

· Condensers

This is the part of the MRI chillers that eliminate the heat from the refrigerant into the cooling water.

It has a special tank within the system which increases residence time thus helping in the elimination of heat.

· Expansion Valves

You will depend on the expansion valve to control the flow of refrigerants by reducing high pressure to lower pressure.

Apart from that, it will help in controlling the quantity of refrigerants that flow into the compressor for further processing.

These are the main parts of the MRI chiller that you ought to look out for when choosing a good MRI chiller.

How Does the MRI Chiller Work?

During the working process of the MRI chillers, you will need the MRI chillers to cool of the generated heat.

MRI chillers have a cold head which is responsible for condensation of helium to original form.

This happens when the helium turns into gas during the cooling process of the MRI magnet.

Here is a step-by – step process that occur in order to cool the cold head which in turn condenses helium.

· Compression of Refrigerant

First, the MRI chiller will release the refrigerant from the main refrigerant storage tank.

It will transfer the refrigerant to the scroll compressor of the MRI chiller.

The scroll chiller will work quietly and with minimal vibration using scrolls to compress the refrigerants.

The compression process will boost the refrigerant’s speed allowing it to flow under high pressure to the evaporator.

· Collection of Heat

This is the main point where heat from the MRI Equipment is taken away.

The collection of heat begins from the cold head which collects the heat from gaseous helium.

To maintain the cold temperature, the cold head will release the heat into systems that will transfer it to evaporators.

While in the evaporator, the refrigerant will collect the heat thus changing form from liquid to gas.

· Release of Heat

With the same pressure, the refrigerant will flow into the condenser where it will spend some time.

During this period, the condenser will increase the residence time as it collects the heat using flowing cold water.

The heat will move from the refrigerant into water thus condensing the refrigerant into liquids.

The water will proceed to eliminate the heat in the water tower.

· Final Stage

Finally, the liquid refrigerant will flow at the same pressure and speed to the expansion valve.

While in the expansion valve, the refrigerant will reduce the pressure and then control refrigerant feed to the compressor.
