heat calc

[just chilling]

what value of watts metre 2 should i use for air conditioining a electronic gaming machine room (pokey machines)

[icecube51]

how mutch heatloss or watt consumption do the have? how many people is there in the room? howmany lights,spots ect..
its the same basic calc like for a office.....

how to calculate the heat load for Ice cream storage room . we want the capacity of the cold room is 25,000 liters ice cream storage. input temperature of the ice cream is -4 deg C and dispatch ice cream temperature is -20 deg c . Door opening 50-120 times /day , 4-7 worker work in the room.

What are room dimensions (W-L-H)?
What are temperatures at other side of room panels?
What is infiltration air max temperature?
Does the floor insulated?
What are material and thickness of room walls?
Describe room placement?
What is pull down time?
Any forklifts?
50-120 openings is lot. You should consider air curtain.

P.S. Next time "please" instead of "I want" will be nicer.

To do it right, you will need the heat dissapation of each machine. There are several possiblilities: You can only get the motor watts and amps. Since the machine does not operate continuously, you would need to find out from the owner about what percentage of each hour a typical machine is in use. If that is given the symbol u for usage factor, then the total heat dissapated per machine would be Q=V*I*u. ; Often, the machine manufacturer can give you the operational and standby heat dissapation, which would be better than using the input.
