Abstract: A fireplace for warming an environment is provided. The fireplace comprise a combustion chamber, a passage, and at least one corona discharge apparatus. The passage is adjacent to the combustion chamber and extends between an inlet and an outlet. The at least one corona discharge apparatus is position within the passage to draw a fluid into the passage through the inlet and to expel the fluid through the outlet.

Abstract: An air conditioning device for heating and/or an environment is provided. The air conditioning device includes a heat exchanging apparatus, a passage, and a corona discharge apparatus. The passage is in thermal communication the heat exchanging apparatus and extends between an inlet and an outlet. The corona discharge apparatus is disposed within the passage to draw a fluid from the environment into the passage through the inlet, move the fluid through the passage to permit the heat exchanger to remove or heat the fluid, and expel the fluid through the outlet into the environment. As such, the environment is cooled or heated. Embodiments of the present invention include package terminal air conditioners (PTACs), room air conditioners (RACs), and mini-split heating and cooling systems.
