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.

Energy recovery ventilator with reduced power consumption

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.

Energy recovery ventilator

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.

Method of operating an energy recovery system

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.

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.

Accessory installation to a heating or cooling system

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. A method of operating an energy recovery system includes flowing a flow of fresh air from an energy recovery ventilator through a supply port into a component of a heating or cooling system. Stale air is flowed from the component through a return port into the energy recovery ventilator.

Cleat arrangement for accessory installation to a heating or cooling system component

An energy recovery ventilator control system is operable to be energized by electrical connection to a heating and cooling system including a thermostat/humidistat in fluid communication with each of an intake air duct and an exhaust air duct. The energy recovery ventilator control system is operable to regulate air temperature and humidity within a building using a temperate and humidity control scheme.

Control system for energy recovery ventilator

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.

An expandable media filter structure is composed largely of biodegradable materials and is environmentally disposable. A plurality of pleated panels are interconnected at their edges so as to be collapsible for storage and shipping purposes but expandable for installation and use. A plurality of ribbons are ultrasonically welded to each of the panels edges, with the ribbon portions between edges being of substantially equal lengths, thereby maintaining equal spacing between the panel edges when the filter is in the expanded condition but allowing an each collapsing of the filter for storage. Forming a part of the nondisposable framework for support of the disposable filter are a pair of end plates which are C-shaped in cross section for slidably receiving an end panel of the media filter therein. The depth of the C-shaped channel is sufficient to allow a plurality of the unexpended pleats to be stored therein so that a single sized filter may be used for various sizes of cabinet openings. The end plates include a pair of slots formed near their ends for attachment to a nondisposable support structure. The nondisposable support structure includes a pair of molded plastic side caps that fit over the respective ends of the filter panels and the end plates. Each side cap has pair of flanges at its opposite ends which act to maintain the filter in its expanded condition when the end plates are placed in abutting position therewith. Each side cap also includes a boss which fits into a respective end plate slot to hold the end plates in their installed positions within the side caps.
