By recovering heat, energy consumption is reduced. Saved energy cut costs and the consumption of coal, natural gas, and other fossil fuels, which eventually leads to carbon dioxide reduction.
The ventilation of buildings significantly adds to the total amount of heat loss. However, constant air exchange is required to introduce fresh air to maintain a comfortable and healthy indoor climate. The heat loss can be reduced when the heat from the exhaust air is transferred to the supply air.
Whereas the savings in commercial and residential ventilation applications might be easier to grasp, industrial ventilation applications also offer many ways to profit from otherwise wasted heat. Consequently, a heat exchanger is almost always a beneficial investment – regardless of whether the exchanger is a rotary or a plate heat exchanger.
All our models save sufficient energy to provide short amortization periods and valuable savings.
In Heatex Select Online you will find a Return on Investment Calculator that approximately indicates the payback amount and time as well as energy saved by installing a Heatex air-to-air heat exchanger. It features both rotary and plate heat exchangers and is located under the “Summary” tab at the end of the calculation process. Below you’ll find a brief tutorial on how to calculate the return on investment of an Heatex air to air heat exchanger in Heatex Select Online. This Calculator is exclusively available in Heatex Select Online.
Key results are the Total yearly energy reduction, Yearly Savings, and the Payback Period.
You will also find an estimation of CO2 emission reduction based on the energy saved by the heat exchanger.
Under Installed Heating/ Cooling Power, we compare the required heating and cooling coil capacity. Under Energy Usage, we compare annual energy demand with and without an air-to-air heat exchanger.
The corresponding graphs support the numbers visually and make it easier to grasp the results.
Note that the heat exchanger price is required to calculate payback time. Otherwise, the result is limited to energy savings only.
Heat exchanger price also can be considered to be the total cost investment, thus payback is calculated for the entire system.
The combustion of fossil fuel contributes to the increasing amount of CO2 in the atmosphere. Higher concentrations of CO2 in the atmosphere adds to the greenhouse effect and increases the average temperature on earth.
The higher average temperature on earth will eventually melt the polar ice caps, increase the ocean level and cause climate change, etc.
Heatex contribution to the reduction of CO2 by cross flow and rotary heat exchangers totals:
Approx. 7.000.000 tons CO2 / year
This is equivalent to the pollution from 2.500.000 Cars!
Total CO2 reduction by the installed base of Heatex rotary heat exchangers:
* Model E, wheel diameter: 1500 mm, well height: 2 mm, width: 200 mm.
Total CO2 reduction by the installed base of Heatex plate heat exchangers:
* Model H2, plate size: 750 mm, well height: 2,1 mm, width: 718 mm.
