Cleaning & Maintenance

Hvac Chillers

Chiller Tube Cleaning

Your team may not be working on chillers that cool the million dollar homes of oil tycoons, but to keep your chiller working efficiently, it needs regular maintenance and cleaning just like the chillers at The Pearl Qatar. Chiller manufacturers have recommended maintenance tasks that include periodic cleaning of the chiller and condenser tubes. Chiller tubes make up the “circulatory system” of the chiller and, just like when humans veins and arteries clog, when tubes are blocked things go bad.

Chiller Maintenance

Chillers in large commercial buildings are often the most expensive piece of equipment in the facility. Not only is a chiller expensive to purchase and install, but chillers “consume more than 50% of electrical energy during seasonal periods of building use.” Keeping tubes and chiller components clean is the simplest way to maintain efficiency throughout the chilled water system. Read any operation and maintenance manual for a chiller and you’ll see the importance of cleaning the equipment highlighted throughout the document.

Chiller Maintenance

Chiller Maintenance

Keeping tubes and chiller components clean is the simplest way to maintain efficiency throughout the chilled water system. Read any operation and maintenance manual for a chiller and you’ll see the importance of cleaning the equipment highlighted throughout the document. For chilled water tubes within the chiller itself, Carrier’s manual recommends to “inspect and clean cooler tubes at the end of the first operating season. Because these tubes have internal ridges, a rotary-type tube cleaning system is necessary to fully clean the tubes.”
Chiller tubes are not the only part of the chiller needing regular cleaning and maintenance. You will also need to clean the condenser coils on its air cooled chillers. “Routine cleaning of coil surfaces is essential to maintain proper operation of the unit. Elimination of contamination and removal of harmful residues will greatly increase the life of the coil and extend the life of the unit.”

How HVAC Chiller Works?

How HVAC Chiller Works?

The HVAC chiller works by changing the physical form of the refrigerant to move the heat from one place to the other.
During the process, the chiller turns from liquid to gas and once it releases heat it returns to a liquid stage.

The Cooling Cycle of an HVAC Chiller

Compressor > Condenser: First the compressor pumps the hot liquid or refrigerant to the condenser. Then, the refrigerant moves to the cold water located on the outside of the component.

Condenser > Metering Device: The liquid flows through the metering device where the flow will be moderated. The liquid refrigerant should drop its pressure to reduce its boiling point.
In this stage, the liquid turns into gas.

Metering Device > Evaporator: The next stage of the gas is to turn into vapor. As it turns into vapor, the refrigerant absorbs the heat from the outside of the chiller to cool the area surrounding it.

Evaporator > Compressor: Now the warm gas moves from the evaporator to the compressor. In the compressor, the temperature and pressure hear the gas once more.
The refrigerant then travels to the condenser and releases the heat, and the cycle begins again.
