Phase Change and AC systems

Many different types of AC units, chillers, floor units, phase change systems. They all produce heat to cool the air. The exhaust usually gets vented outside or a split system has the handler inside and the phase change system outside. Which also requires a fan to cool the coils.

Will it ever be possible to make one that doesn’t produce heat?

I hope so. I have a portable AC unit and the heat it produces is annoying.

By the laws of thermodynamics: nope

That’s what I was thinking, in order to cool you have to have a phase change. But then I was also thinking there has to be a way. Maybe geothermal?

The heat has to go somewhere. So no.

😂

Nope....the systems are only transferring the heat (energy) from one area to another....even with geothermal....
Now if someone develops a means to "shunt" the unwanted heat to another dimension, or via spatial displacement to say deep space then we'd have something----
But in practicality it's best to find other ways to reuse the "excessive heat"

True. I was thinking they should make a condenser that uses the heat to say heat up a tank of water and the water could store that energy. The temps coming off a condenser are 120 in up on a hot summer. If there was someway to re direct it. The issue I see with that is a few, firstly you can’t have a condenser inside, and secondly the condenser needs a lot of airflow to work properly.

Where my condenser is on my patio it has room to breath. I was thinking of putting a clothes line over it about 3 feet up and using it to dry my clothes. It would do it quickly and that’s energy I recovered and not having to run the dryer. I could then dry them out three and put it on a quick air dry only cycle in the dryer with dryer sheets to soften and make the clothes feel dryer fresh.

Why is it such a concern that the a/c units pulls the heat out of your house? The design works. The heats blown outside

There is a concern it causes global warming and re purposing the energy would be cool.

I would worry more about emissions. But definitely not a bad concern

I drive a electric car so I’m more concerned with eliminating other heat sources and re purposing then to use less of something else.

Trump doesn’t seem to care about global warming. But I’m glad you’re on board with good ideas and helping the environment

I am sure you can use a heat exchange system to recover the energy and use it to heat water or other things.

I haven’t found a way to do it without restricting the air flow on the condenser which is a no no.

My house has central air, but the 2nd floor is never properly cooled and requires window unit AC's in the rooms.

As people know, heat rises.

What about converting the waste heat via a thermoelectric generator. Not that you'd get back much.

Democrats here don't really care either. They wouldn't get behind silly pipe dreams like the green new deal if they were serious about this shit.
