What is a Chiller❓❓❓❓
A chiller is a mechanical system that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This cooled liquid is then circulated through air handling units (AHUs), fan coil units (FCUs), or other systems to cool air or equipment.
How Does a Chiller Work? (Step-by-Step Process)
-Evaporation (Cooling Begins)
The chilled water or glycol absorbs heat from the building.
This warm water returns to the evaporator, where refrigerant absorbs this heat.
The refrigerant evaporates (turns into gas) inside the evaporator.
-Compression (Pressure Increases)
The gas moves to the compressor, which increases its pressure and temperature.
Compressors consume the most power in the chiller.
-Condensation (Heat Rejection)
The high-pressure gas flows into the condenser.
In air-cooled chillers, fans blow air over the condenser coils.
In water-cooled chillers, water from a cooling tower removes heat.
The refrigerant releases heat and condenses into a liquid.
-Expansion (Pressure Drops)
The liquid refrigerant flows through an expansion valve.

Understanding the Chilled Water Loop in Commercial HVAC Systems
Dive into the core mechanism of how large buildings stay cool! This diagram highlights the essential Chilled Water Loop for efficient climate control.
Key Components & Process:
The Goal: To distribute cooling capacity throughout the building.
Components:
Chiller: The heart of the system, which generates the cold water.
Chilled Water Pump: Circulates the water through the loop.
Air Handling Unit (AHU): The heat exchanger where the actual air cooling takes place.
The Cooling Process:
Supply: The Chiller cools the water down to 7°C. This cold water is the "Chilled Water Supply" flowing into the AHU.
Heat Exchange: Inside the AHU, the 7°C water absorbs
heat from the return air, cooling the air distributed into the building.
Return: The water, having absorbed the heat load, warms up to 12°C. This "Chilled Water Return" is pumped back to the Chiller to restart the cycle.
Circulation: The Chilled Water Pump ensures continuous circulation and pressure in the loop. This loop is a fundamental part of energy management in large facilities!

🔷 1. What is a Chiller System?
A chiller system cools water, not air directly.
How it works:
Water is cooled inside the chiller.
Chilled water is pumped to AHU or FCU units.
Air is cooled when it passes over the chilled water coil.
Cooling Medium
Chilled Water
🔷 Main Components of a Chiller System
Chiller unit (compressor, evaporator, condenser)
Chilled water pump
Condenser water pump
Cooling tower (for water cooled chillers)
AHU or FCU
Water piping
🔷 How a Chiller System Works (Simple)
The chiller cools water to about 5, 6, or 7°C.
The pump sends chilled water to AHU or FCU.
Air passes over the chilled water coil and becomes cool.
Water returns warmer, around 10, 11, or 12°C, to the chiller.
The cycle repeats continuously.
🔷 2. What is a VRV or VRF System?
A VRV or VRF system cools air directly using refrigerant.
There is no chilled water system.
Each indoor unit receives only the cooling it needs.
Cooling Medium
Refrigerant (DX system)
🔷 Main Components of a VRV System
VRV outdoor unit with inverter compressor
