Abstract

See full text

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, THIGH and TLOW. 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.
