How often should I have my air conditioner serviced?
It is recommended to service your air conditioner at least once a year to ensure it runs efficiently and effectively. Common signs include unusual noises, weak airflow, warm air instead of cool, and a sudden increase in energy bills.

VAM (Vapor Absorption Machine) chillers are a type of refrigeration system used in HVAC applications that operate on the absorption refrigeration cycle, utilizing heat energy instead of electrical energy to generate cooling. These chillers are particularly energy-efficient and environmentally friendly, making them suitable for industrial, commercial, and district cooling applications. Unlike conventional vapor compression chillers, which use mechanical compressors, VAM chillers rely on a thermal compressor consisting of an absorber, generator, and solution pump to achieve refrigeration.
VAM chillers function through an absorption-based refrigeration cycle, involving the following key steps:
- Absorption: The refrigerant (water or ammonia) is absorbed by a chemical solution (lithium bromide or ammonia-water), creating a vacuum in the system.
- Heat Input (Generator Section): The weak absorbent solution is heated using an external heat source (steam, hot water, or gas) to release the refrigerant vapor.
- Condensation: The refrigerant vapor is cooled in the condenser and converted back into liquid form.
- Expansion & Evaporation: The liquid refrigerant undergoes expansion, reducing pressure and temperature, causing it to evaporate and absorb heat from the chilled water circuit.
- Regeneration: The weak absorbent solution is returned to the absorber to restart the cycle.
VAM chillers are classified into single-effect, double-effect, and triple-effect chillers, depending on the number of heat exchange stages and the efficiency levels. Single-effect chillers operate at lower temperatures (80-120°C) and have a Coefficient of Performance (COP) of 0.6-0.8, while double-effect chillers, which use high-temperature steam or gas (140-180°C), achieve a COP of 1.0-1.3. Triple-effect chillers, the most efficient type, use extremely high-temperature sources (>200°C) and can reach a COP of up to 1.8, making them ideal for industrial applications.
The advantages of VAM chillers include reduced electricity consumption, elimination of environmentally harmful refrigerants (CFCs, HFCs), low operating noise, and high energy efficiency, making them particularly useful in pharmaceutical plants, power generation facilities, data centers, hospitals, and district cooling systems. They are widely adopted in process cooling applications where waste heat recovery is essential for sustainable operations, making them a preferred choice in industries aiming for energy efficiency, cost savings, and reduced carbon footprint.
