Abstract
According to various embodiments, a single duct terminal unit includes an air inlet coupled to a casing that allows air to enter the casing, a heat exchanger disposed within the casing and downstream of the inlet relative to airflow entering the casing, a damper disposed downstream of the heat exchanger relative to the airflow entering the casing, the damper controlling airflow through an air outlet, and a control unit in communication with the damper, where the control unit adjusts a positioning of the damper based upon airflow through the air inlet and a requested temperature of airflow through the air outlet.
Claims14
A single duct terminal unit, comprising:
- an air inlet coupled to a casing that allows air to enter the casing;
- a heat exchanger disposed within the casing and downstream of the inlet relative to airflow entering the casing;
- a damper disposed downstream of the heat exchanger relative to the airflow entering the casing, the damper controlling airflow through an air outlet;
- and
- a control unit in communication with the damper, wherein the control unit adjusts a positioning of the damper based upon airflow through the air inlet and a requested temperature of airflow through the air outlet.
A method comprising:
- receiving, in a control unit, a requested temperature associated with an environment;
- determining, in the control unit, a measure of airflow into an air inlet of a single duct terminal unit based on data from an airflow sensor;
- determining, in the control unit, a temperature of airflow into the air inlet;
- determining, in the control unit based on the measure of the airflow and the temperature, a setting for a heat exchanger disposed downstream of the air inlet and upstream of a damper;
- determining, in the control unit based on the measure of the airflow, the temperature, and the setting for the heat exchanger, a damper position of a damper located downstream of the air inlet and the heat exchanger;
- and
- causing, by the control unit, the damper to be position at the damper position and the heat exchanger to activate according to the setting for the heat exchanger.
