How Fresh Air System Cooperate with Air Conditioner


Almost every house and office premise have an air-conditioner system. Poorly managed air-conditioning systems can cost a bomb on electricity bills. Having a basic understanding of how your HVAC system works is crucial with consideration of the rising cost of living, urbanization, and time spent indoors.


HVAC stands for Heating, Ventilation, and Air-Conditioning to regulate Indoor Air Quality, known as IAQ. In a tropical climate, heating is not relevant but managing humidity is. The PURPOSE of Air-Conditioning as the name suggests is to condition indoor air to create comfort with the right temperature, humidity, freshness, and noise. Indoor air is drawn in, processed, and released back into the indoors. Over a period, a lot of dust and bacteria will accumulate in the air conditioner which will threaten respiratory health. Cleaning the filter frequently and getting it serviced periodically is a must.


However, an air conditioner does not generate fresh air. It circulates the indoor air that is high in carbon dioxide (Co2) and other air pollutants that the air-conditioner is not able to treat. Turning on the air conditioner means the room is sealed from outdoor air and without air ventilation. Over a long period, this is detrimental and can cause various ‘Sick Building Syndrome Symptoms’, i.e., tightness and dryness of the skin, nasal allergies, chest tightness, fatigue, and poor breathing. Also known as ‘air-conditioning syndrome’ or ‘air-conditioning disease’.


An airtight environment with high humidity is also conducive to the growth of bacteria, mites, microorganisms, etc. Long-term inhalation of unhealthy air mixed with these microorganisms, residual formaldehyde, benzene, and other harmful substances released from various interior decorating materials and furnishing is an unseen respiratory threat that most people are not aware of.


Recommended remedies include:

  1. The air conditioner should not turn on too long.
  2. Windows should be opened for ventilation occasionally, to promote indoor air circulation.

However, bringing in outdoor air will again increase the temperature and humidity in a tropical climate. The air-conditioner will have to work harder to reduce the indoor temperature and humidity again. Having a humidifier in an air-conditioned room defeats the purpose of regulating air and increasing energy consumption.


Fresh Air System can solve these problems:

  1. Indoor air can be kept comfortable and fresh without frequent openings of windows for ventilation.
  2. The system exhausts indoor air and brings in fresh air to dilute the CO2 with O2.
  3. It is an air-exchanging mechanism with energy exchange capability to keep the cost of cooling the air lower. It complements the air-conditioner to run efficiently and prolongs its lifespan.
  4. An added bipolar ionizer can deactivate indoor air from various viruses and pathogens.
  5. Or, add a non-mechanical non-chemical scientific method to air sanitization to neutralize microbial that escape the filtration system.

IAQ OBJECTIVES that BROAN Fresh Air System can achieve?


Clean indoor air

Not only does it intercept the dust particles from the outdoors, but it efficiently purifies the harmful air pollutant existing in the room, such as viruses, formaldehyde, benzene, etc. So, with BROAN it is safe even if the doors and windows are closed and the air-conditioner is used the whole day.

No more odor

BROAN removes all kinds of indoor odors, such as oil fume from the kitchen, excessive humidity from the bathroom and second-hand smoke, etc.

Our body needs ‘oxygen’ (O2) just as plants need the CO2 to grow

People grew lethargic and students lose focus in study O2 levels are low. Especially those who are more vulnerable such as children, unhealthy people, and the elderly.  Concern over the use of air-conditioners for your baby is solved with a BROAN Fresh Air System.
