A Different Way

Miser HVAC is not trying to make a conventional air conditioner slightly better. It is approaching the thermodynamic process differently.

Conventional approach: electrical energy is used to compress the working medium, and useful expansion energy is normally discarded.

Miser approach: energy put into the air is recovered and reused to help compress more air.

The Miser system uses air as the working medium. This makes it possible to exchange energy between expansion and compression processes in a way that is not practical in ordinary small air-conditioning systems using conventional refrigerant expansion.

Fresh-air ventilation

Ventilation normally has a significant energy cost. Miser is designed to introduce fresh air at a running cost so small that it is effectively free.
