Question

As an experienced engineer, suggest two (2) alternatives to reduce the electrical usage and cost for air ducting unit . The alternative suggested should comprise one (1) technical modification and one (1) human feature.

Answer 1

Electrical Usage:

1. Studies show that heating, ventilating and air conditioning account for 30 percent of the energy used in the average home or small business. In larger buildings, heating and air conditioning can account for almost half of the monthly energy bill.
2. Sealing and insulating ducts increases efficiency, lowers your energy bills, and can often pay for itself in energy savings.

Air ducting unit:

1. system balancing is always recommended to get the full benefit from the total cost incurred on air conditioning system.
2. Large air conditioning systems require optimization of the duct design so as to minimize the total cost, which includes the initial cost of the system and the lifetime operating cost. At present very sophisticated commercial computer software are available for optimizing the duct design. One such method is called as T-Method.
3. As the cost of ducting reduces the usage of power comes down which leads to reduces the pollution in environment which gives a comfortable life to future generation of human.
