Unitary Refrigerant Based Systems

All Air Systems

Air-Water Systems

Advantages

Disadvantages

Applications

Individuals room control is possible and at the same time the system offers all the benefits of a large central system.

The temperature of hot water required for space heating is small, so it is possible to use solar or waste heat for winter heating.

Requires higher maintenance compared to all air systems

Draining of condensate water can be messy and may also create health problem.

All water systems using fan coil units are most suitable in buildings requiring individual room control

Room Air Conditoners

Packages Type Conditioners

All air systems can be classified into:

Advantages

Disadvantages

Applications

1. Single duct, constant volume, single zone system.

2. Single duct, constant volume, multi single zone system.

3. Single duct, variable volume (VAV) system.

4. Dual duct, constant volume system.

5. Dual duct, variable volume (VAV) system.

Effective room air distribution and ventilation is possible under widely varying load conditions.

All air systems present great opportunities for energy conservation.

Since systems are quite large in size, require separate spaces like AHU room.

Difficult to install in existing buildings, as large space is required in false ceiling to lay the ducts.

Precision HVAC applications.

Theater, Auditorium, Functional halls, Retail stores.

Large corporate buildings with varied requirements of heating and cooling

Applications

Advantages

Disadvanatges

Mainly used in exterior buildings with large sensible loads

Suitable for office buildings, hospitals, schools, hotels, apartments and many other.

Positive ventilation can be ensured under all conditions.

Services of indoor units is relatively simpler compared to all water systems.

These systems are limited perimeter to zones.

Initial cost could be high compared to all air systems.
