How do I connect the pumps to the Chiller?

We know the pumps need to push water through the chiller, so we can connect the pump sets to the chillers evaporator inlets. Chilled water is generated in the evaporator so we’ll need to connect that back around to the pumps to create a circuit and distribute the chilled water. Notice there is a common header between the flow and return lines.

How does a chiller work?

A chiller uses a vapor compression mechanical refrigeration system that connects to the process water system through a device called an evaporator. Refrigerant circulates through an evaporator, compressor, condenser and expansion device of a chiller. A thermodynamic process occurs in each of above components of a chiller.

How do you connect a water chiller to a cooling tower?

We will need a set of pumps to push the water through the chiller and around the system so we can drop those in. Then connect those pumps to the condenser inlets and another line out of the condenser and up to the cooling towers, located on the roof.

Do I need a condenser system for an air cooled chiller?

Remember air cooled chillers do not require a condenser system. We will need a set of pumps to push the water through the chiller and around the system so we can drop those in. Then connect those pumps to the condenser inlets and another line out of the condenser and up to the cooling towers, located on the roof.

How do air cooled chillers work and are they better?

If you take a closer look at the variable speed control and centrifugal compressors, air-cooled chillers may make a better choice. How Do Air Cooled Chillers Work? Air-cooled chillers actively absorb heat from process water; they then transfer this heat into the air around the chiller unit.

What is an air-cooled water chiller?

An air-cooled chiller can represent the most practical choice in scenarios where water represents a scarce resource. A typical air-cooled chiller can feature propeller fans or mechanical refrigeration cycles to draw ambient air over a finned coil to condense the refrigerant.

What are the different types of condensers used in chillers?

Thus, chillers can use two different types of condensers, air-cooled and water-cooled. Air-cooled condensers resemble the “radiators” that cool automobile engines. They use a motorized blower to force air across a grid of refrigerant lines.

What are air cooled chillers and where are they located?

They are usually located externally, either up on the roof or at ground level. This is because Air Cooled Chillers do not use cooling towers, instead they dump their heat into the ambient air and therefore need access to a lot of fresh air, in order to reject the unwanted heat from the building.
