Abstract:
HVAC systems and methods for delivering highly efficient heating and cooling using ambient air as the working fluid. A plenum has an upstream inlet and a downstream outlet, each in fluid communication with a target space to be heated or cooled. Ambient air is drawn into the inlet at an incoming pressure and an incoming temperature. The inlet and outlet are gated, respectively, by first and second rotary pumps. A heat exchanger in the plenum transfers heat into or out of the air, provoking a change in air volume within the plenum. The systems and methods are configured to operate essentially between the working temperatures, T HIGH  and T LOW . This technique, called Convergent Refrigeration or counter-conditioning, provides for the reduction of excess refrigerant lift by optimization of the heat transfer temperature. Two Convergent Refrigeration systems can be arranged back-to-back through a common heat exchanger for ultra-high efficiency operation.

Claim (Index 6):
A method for transferring heat from a heat source to a heat sink in a thermodynamic system, said method comprising the steps of:\n A. providing a supply-side sub-system in thermal communication with ambient air in a heat source, B. providing a delivery-side sub-system in thermal communication with ambient air in a heat sink, C. operatively disposing a heat transfer sub-system between the supply-side sub-system and the delivery-side sub-system for moving heat from the supply-side sub-system to the delivery-side sub-system, and D. for each of the supply-side and delivery-side sub-systems, respectively performing the steps of:\n i. providing a plenum having an upstream air inlet and a downstream air outlet, \n ii. inlet gating the plenum at an upstream location with a first pump, the air having an incoming pressure and temperature entering the first pump, \n iii. outlet gating the plenum at a downstream location with a second pump, \n iv. operatively locating a heat exchanger within the plenum in-between the first and second pumps, \n v. moving the air across the heat exchanger within the plenum, \n vi. transferring heat into or out of the air with the heat exchanger, said step of transferring heat including provoking a change in the volume of the air within the plenum, \n vii. operating the first pump relative to the second pump so that air exiting the outlet is approximately equal to the incoming pressure, and \n viii. harvesting work directly from at least one of the first and second pumps in response to changes in the volume of the air in the plenum.
