CONCLUSION

 

            As a conclusion, the Recirculating Air conditioning unit may used to demonstrate and evaluate most of the processes found in practical air conditioning plant, such as heating, cooling, humidification, dehumidification air stream. Sometime two or more of these process are needed to bring air to adesired temperature and humidity level. Various air conditioning processes in psychrometric chart. Notice that simple heating and cooling processes appear as horizontal line on this chart since moisture content of the air remains constant (ω = constant) during this processes. Air is commonly heated and humidified in winter and cooled and dehumidified in summer. Notice how these processes appear on the psychrometric.
