controlling the space dry-bulb temperature. Refer to 

2. Conditioned outdoor air supplied directly to local terminal units, or return ducts of local RTUs, 

which deliver a mixture of the conditioned outdoor air and (conditioned) recirculated air to the 
space. Refer to 

3. Conditioned outdoor air supplied directly to a single space to control the space temperature 

and humidity. For example, this application will provide temperature and humidity control of 
ventilated spaces, such as commercial kitchens or laboratories.
