Abstract: An air conditioning unit includes a passage having a heat exchanger; a blower for blowing air through the passage; a blower motor driving the blower in response to a drive signal; an energy recovery ventilator (ERV), the blower drawing outside air from the ERV; and a controller for adjusting the drive signal in a ventilation mode to reduce power used by the blower motor.

Abstract: An energy recovery system includes a heating and cooling system having a controller and a furnace or fan coil in fluid communication with each of a return air duct and a supply air duct; and an energy recovery ventilator (ERV) having an intake air duct and an exhaust air duct, the ERV being energized by a direct electrical connection to the heating and cooling system. The return air duct is operable to receive stale conditioned air from a conditioned air space while the controller is configured for controlling the ERV to transfer energy from the stale conditioned air to an outside air stream.

Abstract: A method of operating an energy recovery system includes providing a flow of fresh air from an energy recovery ventilator through a supply port into a component of a heating and cooling system. Stale air is blown from the component through a return port into the energy recovery ventilator, the return port including a shield configured to at least partially prevent fresh air flowing from the supply port into the component from recirculating through the return port.

Abstract: An energy recovery ventilator for a heating or cooling system includes a housing and a heat exchanger located in the housing for recovery of thermal energy from a stale airflow of the heating or cooling system. An exhaust fan positioned in the housing is in flow communication with the heat exchanger to urge the stale airflow from a return port disposed in a first side panel of the housing, across the heat exchanger and toward an exhaust port of the energy recovery ventilator. The exhaust fan and the heat exchanger are configured such that the heat exchanger is removable from the housing via a front panel opening in the housing without disturbing a position of the exhaust fan.

Abstract: An energy recovery system includes a heating or cooling system and an accessory operably connected to the heating or cooling system, or a component of the heating or cooling system. One or more accessory interlocking mechanisms are located at the housing interlocked with one or more complimentary interlocking mechanisms located at the system or the component of the heating or cooling system to secure the accessory directly to the component. A method of securing an accessory to a heating or cooling system or a component of a heating or cooling system includes aligning one or more accessory interlocking mechanisms with one or more complimentary interlocking mechanisms The accessory is urged toward an installed position by moving the accessory along a length of the one or more complimentary interlocking mechanisms. The one or more accessory interlocking mechanisms are interlocked with the complimentary interlocking mechanisms to secure the accessory.

Abstract: An energy recovery system includes a heating or cooling system and an energy recovery ventilator operably connected to a component of the heating or cooling system. The energy recovery ventilator includes a supply port extending into the component to provide a supply of fresh airflow from the energy recovery ventilator to the component for use by the component. A return port extends into the component configured to receive a flow of stale air from the component while minimizing ingestion of the fresh air flow from the component into the return port.

Abstract: A fan coil media cabinet for use with a fan coil unit. The cabinet includes an open-sided inner liner having co-joined top, bottom, back, and front panels. The inner panel is mounted within an outer shell having top, bottom, and back walls that are located adjacent to the top, bottom, and back walls of the outer shell. The outer shell contains a ledge that extends about the inner periphery of the shelf upon which the inner liner is seated. The width of the outer shell walls is greater than that of the inner liner panels so that the walls extend outwardly to one side beyond the inner liner. In assembly, the extended wall sections of the outer shell are mounted in contiguous relation with the return inlet of the fan coil and are fastened thereto to create a rigid structure.
