Can you run a small air conditioner 5000 btu in a small room with electronics that emit some heat without using any outside air?

AAnswer I believe that all condenser AC units vent hot air to the outside while also recirculating inside air while cooling it. It would not seem possible to run one of these in the same room unvented since the same hot air would be returned to the room I have a 160 square foot room with two computers, a TV and two laser printers along with all the other stuff that seems to generate lots of heat (cable box, modem, lights, etc). But I insulated the room well and installed a 5000 btu unit high up through the wall from the outside and while it was a pain to do, it works well in the Southern California summers of 100+ days of heat.It also has a remote control which I love I also tried the indoor evaporative cooler but that did not work at all and I returned it to Home Depot Good luck Answer There are small packaged A/C units that use waterinstead of air to absorb the wasteheat.

Some utilize a bucket of chilled water that needs to be periodically replaced while other can be connected to a water supply and drain. Since water has 800X the desity of air, the amount of hot water produced by one of these units is very small compared to the volume of air that a "standard" A/C unit requires. The units also operate as dehumidifiers, which further reduces the heat content of the air in the room ANSWER All air conditioning must discharge the hot air to work They also remove most of the water in the air.

On a rainy day it is totaly ineficient that is why you need a swamp cooler whereby cold water is cycled trough for cooling.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
