Abstract

An air conditioning system includes an air conditioning portion configured to condition a volume of air flowing there-through and an exhaust portion configured to exchange heat with the air conditioning portion through a working fluid. A portion of the volume of air exiting the air conditioning portion is mechanically diverted into the exhaust portion.

First claim

The invention claimed is:

1. An air conditioning system, comprising:
an air conditioning portion configured to condition air entering and flowing there-through, the air conditioning portion including a first heat exchanger for heating or cooling supply air supplied to a conditioned space, the air conditioning portion passing outside air and recirculated air from the conditioned space over the first heat exchanger to produce the supply air,
an exhaust portion configured to exchange heat with the air conditioning portion through a working fluid, the exhaust portion including a second heat exchanger for exchanging heat with outdoor air, and
a diversion channel proximate the air conditioning portion and the exhaust portion;
wherein the diversion channel diverts a portion of the recirculated air into the exhaust portion and passing over the second heat exchanger,
wherein the diversion channel includes a first damper controlling a second portion of recirculated air diverted into the air conditioning portion and passing over the first heat exchanger;
wherein the diversion channel includes a second damper controlling the portion of the recirculated air into the exhaust portion and passing over the second heat exchanger.

2. The system of claim 1 , further comprising an exhaust damper proximate the exhaust portion configured to control a flow of the portion of the volume of entering the exhaust portion.

3. The system of claim 1 , further comprising: an inlet vent proximate the air conditioning portion; and an inlet damper proximate the inlet vent;
wherein the inlet damper is configured to control a flow of external air entering the air conditioning portion.

4. The system of claim 3 , further comprising:
an exit vent proximate the air conditioning portion; and an exit damper proximate the exit vent;
wherein the exit vent is configured to control a flow of conditioned air exiting the system.

5. The system of claim 1 , further comprising at least one fan arranged within the air conditioning portion configured to force air flow through the air conditioning portion.

6. The system of claim 1 , further comprising at least one filter arranged within the air conditioning portion configured to capture particulates from air flowing there-through.

7. The system of claim 1 , further comprising at least one fan arranged within the exhaust portion configured to force air flow through the exhaust portion.

8. The system of claim 1 , further comprising a compressor in fluid communication with the second heat exchanger and the first heat exchanger through the working fluid.

9. The system of claim 8 , further comprising an expansion valve in fluid communication with the first heat exchanger and the second heat exchanger through the working fluid.
