8 Interesting Facts about Heating, Ventilation and Air Conditioning System

Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. The main purpose of HVAC system is to provide thermal comfort and appropriate indoor air quality. HVAC system design is a subdiscipline of mechanical engineering that is based on the principles of thermodynamics, fluid mechanics and heat transfer.

Most of the time, we tend to overlook on the Heating, Ventilation and AIr Conditioning System as the HVAC system has been integrated to our everyday lives. Without further ado, here are some interesting facts that you might not know about the HVAC system:


1. The invention of modern air conditioner

  • While older civilizations had been inching towards a cooling system since the Chinese, Egyptians and Romans have found ways of technologically adapting to the heat.
  • The modern air conditioner was invented by Willis Haviland Carrier in 1902.
  • It was during his time working for an AC repair service company that Carrier created a machine which introduced the true possibility of controlling temperature and humidity while also serving as a ventilation unit.
  • Carrier’s creation had since then been a huge step for mankind in environmental control.


2. The Coolest and Hottest HVAC Temperature Recorded in England

    • The hottest temperature ever recorded in England was in Faversham, Kent on August 10th 2003 when the temperature reached 30.8 degrees Celsius (also 101.3 degrees Fahrenheit) or as the Spanish like to call it, midsummer in Madrid. 
    • The coldest temperature ever recorded in England was in Newport, Shropshire on January 10th 1982. On that day the temperature has dropped to -26.1 degrees Celsius (-15 degrees Fahrenheit).


3. Family Facts about the HVAC System

      • The car air conditioner was invented by a group of brothers: Lowell, Normal, Hiram and Max Goldberg on the 17th of July, 1946.
      • The invention of car air conditioning was found about 44 years after the modern electrical air conditioner by Willis Carrier.
      • Everyone was glad that the Goldberg’s were a family that worked together; or else, our long road trips would feel longer than they do.


4. Air Facts about the HVAC System

      • According to 2017 statistics by the World Health organization, people in the UK are 64 times likely to effect from air pollution compared to Sweden.
      • Proper ventilation is one of the safest ways to improve indoor air quality.
      • Poor ventilation enables pollutants to fester in stale air as humidity from cooking, washing or bathing seeps into our homes.
      • The non-circulation of clean air breeds mould spores and traps dangerous chemicals from the use of everyday items such as cleaning products, bleach and aerosol cans.
      • Poor air circulation can worsen allergic reactions and weakens overall health, especially for those with asthmatic conditions.
      • Although you want to insulate your home to save money, you should never forget to let in fresh air.


5. The Impact of HVAC System

      • Air conditioners did not just refresh our homes as they began to be grown on a mass scale in the 1930’s.
      • Air conditioning has affected the way we approached architecture. Because an appliance could be used to keep families cool in the summer, there was no longer the need to build homes for shade.
      • Breezeways were no longer sought after. Ceilings were made lower, enabling air conditioning units less work to do. It became less surprising to find homes without porches as people could remain indoors in a more comfortable manner.


6. The Origins of the Phrase “Air Conditioning”

A North Carolina textile manufacturer came up with the phrase “air conditioning” in 1906 because the technology actually improved the quality and condition of the cloth being made in his plant.


7. Geothermal power is important as it drills down deep enough to extract moderately warm thermal energy that’s easy to cool and easy to heat, conserving energy that is generally used to balance cold and hot temperatures.


8. The Romans had a very similar concept of indoor heating whereby the floors were laid out as a series of stone slabs with a heat source located below the floor.


The Heating, Ventilation and Air Conditioning System has shaped our lives throughout the years and has integrated into our everyday lives. Now you know all about these 8 interesting facts about the HVAC system.
