Introducing: Heat sources: To the building without

making appropriate reductions in the buildings.

Heat load: Will strain the capacity of the system.

2

Reducing Heat load: reduces

energy operating costs and equipment operating time, which reduces .

System maintenance: repairs and increases equipment life.

3

Definition: any treatment of the environment air within a building is air conditioning.

4

Air cooling is any process that reduces air temperature.

Refrigerated air is produced by a mechanical refrigeration cycle.

5

Examples: Air conditioning: fan that

circulates air, filtering air, heating, cooling, humidifying, dehumidifying.

Air cooling: fan blowing, coolers, swamp coolers, open windows

Refrigerated air: vapor compression, absortion cycles.

Cooling tower:

Condernser pump:

Chiller:

Supply air fan:

Cooling tower

Cooling towers:are heat removal devices used to transfer process waste heat to the atmosphere. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near the dry-bulb air temperature.

Condenser pump

A condensate pump: is a specific type of pump used to pump the condensate (water) produced in an HVAC (heating or cooling), refrigeration, condensing boiler furnace or steam system.

Vapor Compression

Chiller

A chiller: is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required.

Supply air fan

Model AFSI:  Model AFSI centrifugal supply fan comes with a heavy gauge galvanized hood and housing. Sizes 10" to 20". Capacities to 14,000 CFM
