Introduction
A field evaluation of the Ventis system was carried out in Canberra for 18 days (6th – 24th August, 2012). There were 6 outlets in total.
There was also a temperature sensor set-up in a room with no outlet to compare the performance of the system switched on and off during the day
Results
The Ventis system achieved an average of 3.8°C increase in indoor temperatures over the course of testing; the maximum increase being 6°C and also a decrease in humidity of 12%. This was on a typical winter’s day in Canberra averaging 4-14.5°C outside.
The average temperature increase in the roof as compared to outside is approximately 7°C over the course of a day. Roof temperatures can vary between 5 – 32°C, depending on outside temperatures. Graphs on the right are taken from 12th August and System Off data from 18th August.
