Air Handling Units are essential for efficiency and machine safety in industries and large commercial spaces. A proper cooling system not only keeps the space cool but also reduces costs by reducing power consumption. The choice of the right air cooling system depends on various factors such as the size of the area, climatic conditions, energy efficiency, and budget. It is responsible for cooling, heating, filtering, and circulating fresh air inside buildings. Depending on the requirement of the space.
Refcon Engineers is a trusted and leading manufacturer of air handling units in India. Our machines are a perfect blend of quality, durability, and modern technology. Let’s understand in detail the Different types of air handling unit and their benefits.
1. Single Zone Air Handling Unit
A Single Zone AHU is designed to condition and distribute air to only one specific area or zone in a building. It provides uniform air temperature and quality to that single space.
- Where used: Small offices, retail shops, classrooms, and residential complexes.
- Features: Simple design, lower initial cost, and easy operation.
- Limitations: Cannot provide different temperatures for different spaces; if the whole system is on, the zone must be cooled or heated together.
2. Multi-Zone Air Handling Unit
A Multi-Zone AHU is capable of serving multiple rooms or areas at the same time. It has dampers and control mechanisms that allow separate temperature control for each zone.
- Where used: Hospitals, malls, schools, hotels, and large office buildings.
- Features: Flexible temperature control, efficient air distribution, and better comfort for occupants.
- Limitations: More complex system, higher installation and maintenance cost.
3. Packaged Air Handling Unit
A Packaged AHU is a complete factory-built unit where all major components (like fans, coils, filters, dampers, humidifiers) are pre-assembled in a compact casing. It is plug-and-play, meaning installation is quick and easy.
- Where used: Industries, commercial buildings, data centers, and large halls.
- Features: Space-saving, reliable performance, quick installation, and less on-site work.
- Limitations: Limited customization compared to modular AHUs.
4. Modular Air Handling Unit
A Modular AHU is made up of separate sections or modules such as filter section, cooling coil section, fan section, mixing chamber, and heat recovery system. Each module can be added or removed as per requirement.
- Where used: Pharma industries, cleanrooms, laboratories, large commercial complexes, and hospitals.
- Features: High flexibility, easy to customize, expandable, and suitable for specialized air quality needs.
- Limitations: Requires more installation space and slightly higher cost due to customization.
5. Evaporative Cooling System
Evaporative cooling system terracotta air conditioner, also known as swamp cooling, uses the natural process of water evaporation to cool the air. Hot air passes through water-saturated cooling pads, and as the water evaporates, the air temperature drops, resulting in cool and fresh air being circulated indoors. Evaporative cooling unit price depends on various factors about industry size and their requirements.
Advantages
- Energy-Efficient: Uses significantly less electricity compared to conventional air conditioning systems.
- Fresh Air Supply: Continuously brings in fresh air from outside instead of recirculating indoor air.
Working Principles of Evaporative Cooling System
- Warm Air Intake: Warm, dry air is drawn into the system by a fan.
- Water-Soaked Pads: The air passes through specially designed pads soaked with water.
- Evaporation and Cooling: As the air flows over the wet pads, water evaporates, absorbing heat from the air and lowering its temperature.
- Increased Humidity: The evaporation process also increases the humidity of the air.
- Cool Air Circulation: The cooled, humid air is then circulated throughout the space by the fan.
6. Chilled Water Cooling System
A chilled water cooling system is an advanced cooling technology that uses chilled water to cool air. This system is typically installed in large commercial buildings, industrial plants, and data centers, where consistent and efficient cooling is required. Refcon Engineering has many types of cooling systems including chilled water AC system, Air Conditioning (Refrigerant-Based Cooling).
- Chiller unit – This machine cools water to a very low temperature (typically 6-7°C).
- Pumps and pipelines – Chilled water circulates throughout the system through pipelines.
- Air handling unit (AHU) / fan coil unit (FCU) – These units cool the air using chilled water and then circulate the cooled air throughout the room or hall.
7. Hybrid Air Cooling System
Hybrid cooling systems combine traditional cooling methods such as evaporative cooling with advanced refrigeration technology. This combination enhances cooling efficiency while significantly reducing energy consumption.
