Central systems are used for circulating conditioned air to different parts of the building. The primary advantage of such systems is maintaining of uniform temperatures throughout the building. While designing the system air distribution, temperatures and cost-effectiveness are important criteria. The system is comprised of plenums for supply and return; ducts; fittings; and associated components. Air handling units operate as a package unit with plant units. The system is assembled with pipework, ductwork and electrical connections at the site.

The fan is placed upstream of the heater battery and cooling coil as the fans operate ideally when the system resistance of the outlet. The air distribution system is a separate distribution system as there are the specific temperature and humidity requirements. The air leakage limit is in accordance with the operating static pressure in excess of 750Pa according to the Code of Practice. The fan system has been designed as the sum of all fans required for the design conditions. Considerations include intake of outdoor air; circulation of air between heating and cooling source and space to be air-conditioned.

Exhaust is to the outdoors. According to the Code of Practice Supply of constant air volume at design conditions does not exceed 1.6 W per L/s based on total fan motor power required for constant air volume fan system; and 2.1 W per K/s of supply air quantity for variable air volume system. Each floor has been considered as a zone, and individual thermostatic controls operate each air conditioned zone. However, controls do not permit heating and cooling operation simultaneously, or heating previously cooled air or vice versa.

The air conditioning system includes automatic control devices for regulation of temperature. The thermostatic controls are able of adjusting setpoint temperature for the space being served. A humidistat has been included as a part of a system that is capable of adding or removing moisture for maintaining specific humidity levels.
