DESIGN PROBLEM & SOLUTION

ENCOUNTERED PROBLEM: AIR CONDITIONER

Due to the current weather of Malaysia, Which eliminates the cool weather and has been exposed to more radiant weather, making the environment and surrounding so hot and humid outside. The air feels so thick and sticky.

The existing AC in my room does not make the room cooler and it is hard to have a peaceful nap. Moreover, the AC is not energy efficient because the cooling effect of the AC was not functioning well and cooled the room quite slowly. The issue continued even after an AC maintenance.

SOLUTION: REPLACE A NEW AIR CONDITIONER

I wanted to replace the existing AC to a better AC, which provides energy efficient and less maintenance, therefore the inverter air conditioner is by far the most energy efficient. It is more economical and smooth in operation than the fixed-speed air conditioner. It consumes nominal electricity due to its varying speed compressor and it is good for the environment Moreover, the inverter AC is quite expensive than non-inverter AC but it doesn't require much maintenance.

Old Design

OLD A/C CALCULATION

Wattage= 865W

Energy= Power X Time.

= 865W x 6HRS

= 865W 1000

= 0 865KW

= 0 865KW x 6HRS

= 5.19KW/H

In month (assuming the month has 30 days)

= 5.19KW/H x 30

= 155.7KW/H

NEW A/C CALCULATION

Wattage= 865W

Energy= Power X Time.

= 1200W x 6HRS

= 1200W 1000 = 1 2KW x 6HRS = 7.2KW/H

= 1 2KW

In month (assuming the month has 30 days)

= 7.2KW/H x 30

= 216KW/H
