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 1):
A method for transferring heat between a heat exchanger and a gaseous medium in a thermodynamic system, said method comprising the steps of:\n providing a plenum for a gaseous heat transfer medium, inlet gating the plenum at an upstream location with an inlet gate, the gaseous medium having an incoming pressure and temperature entering the inlet gate, outlet gating the plenum at a downstream location with an outlet gate, operatively locating a heat exchanger within the plenum in-between the inlet gate and the outlet gate, transferring heat into or out of the gaseous medium with the heat exchanger, the heat exchanger having a Heat Exchanger Temperature, the gaseous medium in the plenum upstream of the heat exchanger having an Approaching Temperature, counter-conditioning the Approaching Temperature by reducing the Approaching Temperature below the Heat Exchanger Temperature when heat is transferred into the gaseous medium from the heat exchanger and elevating the Approaching Temperature above the Heat Exchanger Temperature when heat is transferred out of the gaseous medium to the heat exchanger, and returning the gaseous medium to the incoming pressure within the outlet gate, said returning step including harvesting work directly from at least one of the inlet gate and the outlet gate.
