Air conditioner Energy consumption for my Scenario

AI Thread Summary
The discussion centers on researching the energy consumption of room air conditioners based on their BEE ratings. Participants emphasize the importance of cooling load calculations, noting that insufficient details about room insulation hinder accurate estimations. The scenario includes specific parameters like average temperatures, room size, window dimensions, occupancy, and desired temperature, but lacks clarity on insulation values. There is a call for more detailed constraints to provide meaningful insights into energy consumption benchmarks. Overall, accurate calculations depend on understanding both the room's construction and the air conditioner's capacity.

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?
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
