BACKGROUND

The present disclosure generally relates to heating, ventilation, and/or air conditioning (HVAC) systems and, more particularly, to an auxiliary economizer incorporated within an HVAC system.

This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present techniques, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

An HVAC system generally facilitates air flow to a conditioned space within a building or residence via one or more blowers. Further, the air flow may be drawn from the conditioned space, for example via return air ductwork, and/or from the environment, for example via an economizer. The economizer may allow ventilation of the conditioned space with the environmental air. Further, the HVAC system may condition a return air flow and/or the environmental air, for example, by directing the air flow through one or more heat exchangers and/or other HVAC sections. In some scenarios, directing the environmental air through multiple sections of the HVAC system may cause a pressure drop along the air flow path, and, thus, decrease a flow rate of the air flow and/or increase current draw of the blowers.

SUMMARY

This section provides a brief summary of certain embodiments described in the present disclosure to facilitate a better understanding of the present disclosure. Accordingly, it should be understood that this section should be read in this light and not to limit the scope of the present disclosure. Indeed, the present disclosure may encompass a variety of aspects not summarized in this section.

The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) unit. The HVAC unit may include a supply fan section having a supply fan disposed therein to force a supply air flow through a discharge plenum of the HVAC unit. The HVAC unit may also include an economizer positioned adjacent the supply fan section to receive an outdoor air flow and direct the outdoor air flow into the supply fan section.

The present disclosure also relates to an economizer, which may include an air inlet to receive an environmental air flow and an air outlet to direct the environmental air flow into a heating, ventilation, and/or air conditioning (HVAC) unit proximate a blower section of the HVAC unit, such that the environmental air flow bypasses an evaporator coil of the HVAC unit prior to being discharged via a plenum section of the HVAC unit. The economizer may also include a damper to regulate a flow rate of the environmental air flow from the air inlet to the air outlet.

The present disclosure also relates to a heating, ventilation, and/or air conditioning (HVAC) unit, which may include a first economizer to direct a first environmental air flow into an air flow path of the HVAC unit and a second economizer to direct a second environmental air flow into the air flow path. The HVAC unit may also include a conditioning section having a heat exchange component. The conditioning section may be disposed between the first economizer and the second economizer, relative to a direction of air flow through the air flow path, and the heat exchanger component may condition the air flow.
