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.

This diagram illustrates the components of a central heating and cooling system in a home. The system includes forced-air heating, where warm air is distributed through supply ducts and registers, providing even heating throughout the space. The furnace, located in the basement, works alongside a central air conditioner to regulate temperature and humidity. The plenum distributes the conditioned air, while the cold air return ducts channel air back into the system for reconditioning. The thermostat controls the temperature, and the room air conditioner helps manage indoor climate during warmer months. Additional devices such as a dehumidifier and humidifier work to maintain optimal moisture levels. The system is designed for comfort and efficiency, with filters that help purify the air.
🔥 HVAC VACUUM PROCESS (BEFORE GAS CHARGING) 🔧
✅ Connect Double Manifold Gauge Set
🔵 Low Side → Suction Line
🔴 High Side → Discharge Line
🟡 Center Hose → Vacuum Pump
⚡ Start Vacuum Pump
➡️ Open Both Valves (High + Low)
💨 Evacuate Air & Moisture
✔️ Remove Non-Condensable Gases
✔️ Prevent System Damage
⏱️ Run for 20–30 Minutes
📉 Achieve Deep Vacuum (-29 inHg or 500 Microns)
🛑 Close Valves & Stop Pump
🔍 Hold Vacuum (Leak Test)
❄️ System Ready for Refrigerant Charging!
💡 Pro Tip:
Never skip vacuuming — Moisture = Compressor Failure ⚠️
