As it currently stands, the Building Code of Australia (BCA) mandates a minimum of 10% fresh air to be brought in through each AC unit.
This can be done through various means and via different types of systems such as rooftop package units, in-ceiling ducted units, hi-wall units & cassette units.
However, fresh air supplies to hi-wall units and cassettes are often neglected due to the additional expense and difficulties of achieving this in practice.
This 10% is the minimum based on considerations such as size of the space being conditioned, the amount of people based on the size and purpose of that specific area or office.
Unfortunately these considerations do not take into account several factors that will affect the 10% fresh air target from being achieved. For example, some environments have more people in them than originally anticipated and/or changes can be made with partitioning.
It is not practical (sometimes impossible) to be opening windows or doors, especially during Melbourne’s peak Summer and Winter seasons, to compensate for the lack of fresh air in these environments.
Finally the one thing that is perhaps the most important consideration of all, which is not currently mandated, is air quality monitoring and active control of flushing these spaces with outside air.
By introducing monitoring and active control measures, a safe and healthy work place is more likely to be created.
This can benefit the workplace by bringing a higher level of productivity, as well as decreasing days lost to illness.
With all of this in mind we at Coldflow Air Conditioning, using our cutting edge innovations and 50 years’ experience at the forefront of the industry, can offer you the tools to achieve this immediately.
The term ‘sick building syndrome’ (SBS) is used to describe an excess of chronic symptoms.
Some short term symptoms may be described as irritation of the skin, eyes and throat
Headache, drowsiness and general irritancy are also indicators of SBS.
Long term symptoms such as cancer and respiratory disease may be caused by long term, periodic exposure to chemicals such as formaldehyde and microscopic fibres such as asbestos.
We have our team ready to work with you via your preferred online remote meeting place, or as restrictions allow, in person.
This is my second system that Coldflow have installed and I'm very happy with the result.
2 head air conditioning system installation was quick and tidy. Even though the cassettes are more complicated and involved to install. All the guys cleaned up after themselves and took all the rubbish away. Excellent service and workmanship, even when it rained and then heat (it's Melbourne).
System work a treat, just waiting for the heatwave to arrive. Great work by the team.
I was extremely happy with the service provided by Coldflow.
I had a ducted cooling system installed. The team turned up on time and completed the job the same day. The guys were courteous and completed the job with a minimum of fuss and disruption. The workmanship was excellent and all ducts were located as per our agreement. They placed drop sheets wherever required and cleaned up after completion. Again was very happy with the service provided by all the crew.
Replaced gas ducted unit. Installation was the perfect I have ever seen and the installers cleanup and did more than they were suppose to do. Customer service focused and really good company to work with. Have also got my cooling installed from them last year, so recommended already to friends and to anyone needing Heating and Cooling
From my first conversation with a consultant, I felt confident that Coldflow had the experience and knowledge I was looking for. I was thrilled with the level of customer service I received and follow up from them. The installers were professional and helpful and on time. I am very happy with the evaporative cooling unit we chose, thanks to the assistance and guidance of our consultant. I highly recommend Coldflow and would use them again.
Very good service. David the Sales consultant understood what i wanted with no pressure, and was patient. Installers were friendly. Had one one problem with controller, but they have back the next day and was promptly fixed. Thanks again
Thanks to Craig at Coldflow. He listened to me, about how cold and hot certain rooms were. Other companies just tried to sell me what they wanted. Very good service, very happy with my heating and cooling.
