Building types and essentials of air conditioning

Short answer

Educational building: used for teaching/learning (schools, colleges, universities). Residential building: used for living/sleeping (houses, flats, hostels, hotels). Essentials of air conditioning: temperature control (22–26°C), humidity control (40–60% RH), air filtration, air circulation/distribution, fresh air supply, refrigeration plant, controls (thermostat/humidistat), insulated/sealed building, proper load calculation and equipment sizing.

Define educational and residential building. What are the essentials of air conditioning? Explain.

Educational building

A building used for teaching and learning: schools, colleges, universities, training centres, with classrooms, laboratories, libraries and offices.

Residential building

A building where people live and sleep: houses, flats, hostels, dormitories, hotels, and apartments. (NBC groups educational as one use class and residential as another.)

Essentials of air conditioning

  1. Temperature control: Cooling in summer and heating in winter to hold about 22 to 26 °C.
  2. Humidity control: Keep relative humidity about 40 to 60 % by humidifying or dehumidifying.
  3. Air filtration / cleaning: Dust, pollen, smoke and bacteria are removed by filters.
  4. Air circulation and distribution: A fan and ducts give uniform air movement, without draught.
  5. Fresh air supply: A fraction of outside air is mixed with the recirculated air.
  6. Refrigeration plant: compressor, condenser, expansion valve and evaporator for cooling.
  7. Controls: thermostat and humidistat for automatic operation.
  8. Insulated building and sealed openings: This reduces the load.
  9. Proper load calculation and equipment sizing: considering occupants, lights, solar gain and fresh air.
