Air conditioner Energy consumption for my Scenario

[vimalraj]

I am currently doing a research on energy consumption of Room Air conditioners based on BEE rating. Are there any available industry benchmarks for energy consumption of Air conditioners by rating of the AC?

For instance, for the given scenario (defined constants) below, any inputs on how to arrive at standard (estimated) consumption?Scenario:

1. Average city temperature: 30 deg C (day), 22 deg C (night)

2. Room Size: 16'x10'x12' (ground floor, in a building with 3 floors)

3. Windows

a. East facing - 6'x6', 1 window

b. West facing - 6'x6', 1 window

c. Other sides - NIL

4. Occupancy – 2 people

5. Run time – 16 hrs (8 hrs during the day, 8 hrs during the night)

6. Desired Room Temperature – 21 deg Ca.

Welcome to PF!

Well, if you are starting with room construction, what you need are cooling load calculations. But you haven't provided enough details about the room construction (insulation values) to calculate anything.

You've also stated a run-time and said something about capacity (all the question marks are not helpful in understanding what you are trying to say), which may provide completely separate and contradictory constraints. Maybe you just need to build a table of capacity vs energy use based on the run-time.

You'll need to provide more details of the goal here or better constraints to be able to get an answer that is meaningful. Is this some sort of homework or open-ended project?

Under steady state conditions the heat removed by the AC is equal to the heat entering via the walls, windows and ventilation plus other heat sources such as people. So you need to know how well insulated the building is.

Welcome to the PF.

You didn't answer Russ' question -- is this for schoolwork?
