Abstract
A terminal unit of a heating, ventilation, and/or air conditioning (HVAC) system includes a fan configured to provide an airflow through the HVAC unit by drawing the airflow into a fan inlet and expelling the airflow out of a fan outlet. The terminal unit also includes an inlet diffuser disposed upstream of the fan inlet relative to a direction of the airflow, wherein the inlet diffuser includes a first layer of perforated metal and a second layer of perforated metal disposed between the first layer of perforated metal and the fan inlet.
Claims20
A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- an enclosure defining a chamber having a first corner and a second corner opposing the first corner;
- a fan disposed in the chamber and configured to provide an airflow through the HVAC system by drawing the airflow into a fan inlet and expelling the airflow out of a fan outlet;
- and
- an inlet diffuser disposed in the chamber upstream of the fan inlet relative to a direction of the airflow, wherein the inlet diffuser is coupled to the enclosure at the first corner of the chamber and at a mid-section of an enclosure wall extending from and partially defining the second corner of the chamber, and the inlet diffuser includes a first layer of perforated metal and a second layer of perforated metal disposed adjacent to the first layer of perforated metal such that the first layer of perforated metal and the second layer of perforated metal are arranged in series relative to the airflow and configured to enable the airflow to pass therethrough.
A terminal unit of a heating, ventilation, and/or air conditioning (HVAC) system, the terminal unit comprising:
- a housing defining an airflow path including a chamber, the chamber including a first corner and a second corner opposing the first corner;
- a fan disposed in the chamber and configured to move an airflow through the chamber and into a room;
- and
- an inlet diffuser disposed in the chamber upstream of the fan, wherein the inlet diffuser is coupled to the housing at the first corner of the chamber and at a mid-section of a housing wall extending from and partially defining the second corner of the chamber, and the inlet diffuser includes a first layer of perforated metal and a second layer of perforated metal disposed between the first layer of perforated metal and the fan such that the first layer of perforated metal and the second layer of perforated metal are arranged in series relative to the airflow and configured to enable the airflow to pass therethrough.
A terminal unit of a heating, ventilation, and/or air conditioning (HVAC) system, the terminal unit comprising:
- a housing defining a first chamber and a second chamber of an airflow path with a separating wall partially separating the first chamber from the second chamber, wherein a conditioned air inlet opening into the first chamber, a return air inlet opening into the second chamber, and an air outlet are formed in panels of the housing;
- a fan disposed in the first chamber and configured to bias an airflow from the conditioned air inlet to the air outlet;
- and
- an inlet diffuser disposed in the first chamber of the airflow path adjacent to the conditioned air inlet and between the conditioned air inlet and the air outlet, wherein the inlet diffuser is coupled to a first corner of the first chamber and to a mid-section of a housing wall extending from and partially defining the a second corner of the first chamber, and wherein the inlet diffuser includes a first layer of perforated metal and a second layer of perforated metal disposed between the fan and the first layer of perforated metal such that the first layer of perforated metal and the second layer of perforated metal are arranged in series relative to the airflow and configured to enable the airflow to pass therethrough.
