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?
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
