Abstract: The dual-cycle and dual-outlet air conditioner includes two separate condensation-evaporation cycles that operate independently with respect to one another, but are contained within the same housing. Each cycle includes its own evaporator and condenser, but with a common return air intake/evaporator blower and a common condenser/exhaust fan. Two separate streams of cooled air are produced by the two separate evaporators, which may then be transferred through two separate ducts to supply cooled air to different zones within a building. The two separate condensation-evaporation cycles may be independently controlled by separate thermostats in the different zones of the building.

Abstract: An energy efficient air conditioner is configured to use a portion of cooled indoor air to cool a condenser in a continuous evaporation-compression-condensation cycle. Ambient air from an indoor environment enters a housing of the air conditioner through a first air inlet. A first fan draws the air over an evaporator coil for cooling, and after cooling, directs the air back into the indoor environment through a first air outlet. A second fan draws a portion of the cooled air (e.g., a cooled exhaust air stream drawn from ventilated areas of a house) back into the housing through a second air inlet, where it is passed over a condenser coil. Heat exchange with the condenser coil creates heated exhaust, and the second fan directs the heated exhaust out of the housing, into an outdoor environment, through a second air outlet.
