Heating Ventilation Air Conditioning System Energy Cost Optimization by Using Building Management System

Heating, ventilation and air conditioning will carries the major portion of the total money spent by any company on the energy. Even small adjustments to the HVAC systems will improve the building internal comfort condition and can result energy savings, hence we can save money. Improvement of the energy efficiency will benefit in profitability of the organization. HVAC System is more frequently applied in industrial facilities in living compounds and offices. The fully automatic control of these systems is impossible to avoid while going to save the energy consumed by the system. Basic parameter of air that needs to be monitored and regulated is temperature. The inside air temperature depends on the outside air temperature, mechanical Infrastructure and occupancy in the zone. For this reason it is necessary to produce a control technique capable of monitoring and controlling the temperature. By using the signals given by the sensing elements such as sensors, control system will perform full automatic control of HVAC system by comparing the current temperature with temperature defined in the Building Management system hence regulate the flow of chilled air into the zone by adjusting the Variable air volume throttle which acts as a gateway to the chilled air into the specified zone. Hence we can maintain desired comfort level inside the building. The zone control will allows user to maintain different temperature in different zone. Hence can save chilled air flow into the building, which will result in less load on chiller. Hence we can some amount of energy which consumed by the chiller, so we can reduce the cost which is spent on the energy.
