In HVACs, we are burning excess power (and burning our pockets) by sucking outside
HOT or COLD (and polluted) air via the “fresh air” louvers to dilute internal VOC, CO2, Oxygen levels.
a) You shall not have to open the "outdoor fresh-air" suction louvers at all (or use it at a negligibly small capacity), since you're rather INCREASING FRESH AIR INJECTION, by continuously supplying indoor fresh air, and maintaining exceedingly high standards of INDOOR AIR QUALITY OVER-QUALIFYING ASHRAE, OSHA, ANSL USA norms!
Thus, you do not have to invite outside polluted & HOT / COLD air to dilute inside VOC, and thereby save huge amount on electricity consumed, which is otherwise required to regularly cool down / heat up the outdoor air through the louvers carrying unwanted temperatures.
b) Moreover, it prevents bio-mass formation inside the duct. For this reason, the duct is also saved from corrosion.
You save the amount regularly spent on cleaning and maintenance of ducts too!
c) You can even reduce the cooling capacity of HVACs, TFA, and thereby save huge on capital costs.
d) Complete & much more advanced replacement of Heat exchangers / Heat Recovery Units
1. Lesser capital cost
2. And way higher Power-Savings (upto 25-30% MONTHLY)
3. Highest IAQ parameters of nullified Infection levels, higher Oxygen levels, reduced CO2, CO, SOx, NOx, PM levels (all over-qualifying ASHRAE, ANSL, OSHA USA standards)
4. Faster RoI
5. No change in HVAC engineering design, hence perfect for both Retrofit installations & New installations
6. Nominal space requirement, way lesser than ERV units
7. Reduction in Duct cleaning costs
8. Globally admired.
