This document discusses central air conditioning systems. It introduces the authors and defines air conditioning as cooling and dehumidifying indoor air for thermal comfort. It describes the main components of a central air conditioning system, which includes a two-stage compressor, condensing unit, evaporating unit known as an air handling unit, ducts, filters, thermostats, and optional auxiliary units. The document distinguishes between comfort air conditioning for buildings and process air conditioning designed for specific industrial processes.

- 3. INTRODUCTIONWHAT IS AIR CONDITIONING ?Cooling and dehumidification of indoor air for thermal comfort . Any form of cooling, heating, ventilation or disinfection that modifies the condition of air .AIR CONDITIONER -An appliance, system, or mechanism . Stabilize the air temperature and humidity within an area , using a refrigeration cycle .
- 4. Types of Air Conditioning Systems -Window Air Conditioning SystemSplit Air Conditioner SystemPackaged Air ConditionersCentral Air Conditioning PlantsChilled-water and Cooling-tower AC Units
- 5. CENTRAL AIR-CONDITIONING- Central Air-conditioning applications are divided into two types -1) Comfort2) Process
- 6. COMFORT AIR-CONDITIONINGBuilding indoor environment that remains relatively constant in a range preferred by humans despite changes in external weather conditions or in internal heat loads.Allows buildings to be taller .Comfort applications Low-Rise Residential buildingsHigh-Rise Residential buildingsInstitutional buildingsIndustrial spaces Transportation
- 7. PROCESS AIR-CONDITIONINGSuitable environment for a process being carried out, regardless of internal heat and humidity loads and external weather conditions.The needs of the process that determine conditions, not human preference.Process applications Hospital operating theatresClean rooms for the production of integrated circuits, pharmaceuticalsAircraft air conditioningFood cooking and processing areas
