The resulting supply air is then sent to the conditioned zones by variable rate supply fans.  In the purge or free cooling modes, the return air damper is closed, the outside air damper is at full open, and the airhandler operates with 100% of outside air.  These are even operated in a basic on­off fashion with a very basic control loop.  Typical operating modes include: • Startup, • Occupied, • Unoccupied or night and • Purge or free­cooling.  One approach is to calculate the amount of heat that needs to be transferred and divide it up according to the capacity of the startup equipment.

A fan located inside the building distributes the warmed or cooled air throughout the interior.  An open loop system can be installed where an adequate supply of suitable water is available and open discharge is feasible.  During summer cooling, the heat from inside the building is returned to the earth with the same high efficiency.  Special financing may also be available through the local utility or through the producer of the system.  A gas­fired heat pump can deliver air outlet temperatures that are 10 to 15°F warmer than electric air­to­air heat pumps and will operate more efficiently at lower outdoor temperatures.

A pressure deviation from the setpoint value causes a con­ Page 21 trol signal to be sent to the controlled device.  The controlled device to modify the fan performance may be an inlet or discharge damper actuator, an inlet guide vane actuator, a mechanical speed control device, or a variable frequency drive. Air Quality Control of the air quality may be done by the following methods depending on the degree of contamination: • Dilution with outside ventilating air, • Filtration of particulate matter with air filters, • Filtration of gaseous contaminants with odor adsorbent or odor oxidant filters and • Hooding of contaminating processes.
