Abstract

An air terminal for a heating or air conditioning system including a housing, a fresh air inlet in the housing to supply a fresh airflow to the air terminal, an outlet diffuser at the housing to allow airflow from the air terminal into a conditioned space, an inlet diffuser located at the housing to allow return airflow from the conditioned space into the air terminal, a coil located in the housing to condition the fresh airflow and/or the return airflow prior to the fresh airflow and/or the return airflow flowing into the conditioned space. A fan is located in the housing to urge return airflow through the inlet diffuser and across the coil. The fan and the inlet diffuser are located at a first side of the coil and the outlet diffuser and the fresh air inlet are located at a second side of the coil opposite the first side.

First claim

The invention claimed is:

1. An air terminal for a heating or air conditioning system comprising:
a housing:
a fresh air inlet in the housing to supply a fresh airflow to the air terminal;
an outlet diffuser disposed at the housing to allow airflow from the air terminal into a conditioned space;
an inlet diffuser disposed at the housing to allow return airflow from the conditioned space into the air terminal;
a coil disposed in the housing through which a heat transfer medium is flowable to condition the fresh airflow and/or the return airflow upstream of the fresh airflow and/or the return airflow flowing through the outlet diffuser into the conditioned space;
a fan disposed in the housing to urge return airflow through the inlet diffuser and across the coil, the fan and the inlet diffuser each disposed at a first side of the coil and the outlet diffuser and the fresh air inlet each disposed at a second side of the coil opposite the first side; and,
further comprising a nozzle to direct the fresh airflow across the coil.

2. The air terminal of claim 1 , further comprising a CO 2 sensor operably connected to the air terminal to measure a CO 2 level in the conditioned space.

3. The air terminal of claim 1 , further comprising an air damper disposed at the fresh air inlet to regulate the fresh airflow into the terminal.

4. The air terminal of claim 1 , further comprising a filter disposed upstream of the fan to filter the return airflow.

5. The air terminal of claim 1 , further comprising a drip pan disposed at the coil to capture condensation from the coil.
