Abstract
An apparatus for heating and cooling which features a unique energy recovery ventilation apparatus and method. During energy recovery ventilation, a cycling damper controls the flow of warm and cool air to maintain the inside air temperature when inside air is cycled to the outside. The outside air is then warmed or cooled when drawn to the inside.
Claims5
Heating/cooling/ventilation unit comprising:
- a. a casing having a condenser plenum and an evaporator plenum, said condenser plenum having a first and second end and said evaporator plenum having a first and second end, said casing having two outside air ports, an inside air outlet, and an inside air inlet connected to said plenums;
- b. a compressor connected to an evaporator with evaporator fins and connected to a condenser with condenser fins housed within said condenser plenum and said evaporator plenum;
- c. turning vanes housed within said plenums;
- d. an outside damper pivotably connected to said casing and positioned between the first end of the evaporator plenum and the first end of the condenser plenum, a cycling damper pivotably connected within said inside air outlet and positioned between the second end of the evaporator plenum and the second end of the condenser plenum, and a return damper between the outside damper, said cycling damper, said inside air inlet and one of the outside air ports;
- e. means for controlling said cycling damper;
- and
- f. a supply fan located between an inside air inlet and an outside air inlet both of which are interconnected to said plenums and a return fan within an inside air outlet interconnected to said plenums and an outside air outlet interconnected to said plenums.
