What is a heat exchanger core?
What is a heat exchanger core?
Xchanger heat exchanger fin-tube cores can be installed in ductwork as original or replace existing units to heat and cool low pressure gas streams.
How do you size an air to air heat exchanger?
An air to air heat exchanger’s capacity is specified in Watts per degree Fahrenheit (and also Centigrade) temperature difference. For a rough estimate, calculate the heat load of the enclosure in Watts and then divide the heat load by the capacity of your air to air heat exchanger.
Will an air exchanger help cool the house?
Air exchangers form an integral part of heating and cooling systems in all kinds of houses, but they are not built particularly for either heating or cooling. Air exchangers do not provide heating or cooling in your house. Instead, they channel fresh air in your home without requiring you to open windows or doors.
How efficient are air to heat exchangers?
The longer the air runs in the unit, the greater the heat exchange. The percentage of heat recovery is the efficiency of the unit. Efficiencies usually range around 80 percent.
What is the overall heat transfer coefficient?
The overall heat transfer coefficient, or U-value, refers to how well heat is conducted through over a series of resistant mediums. Its units are the W/(m2°C) [Btu/(hr-ft2°F)].
Which type of heat exchanger is most efficient?
Plate exchanger is the most efficient due to turbulent flow on both sides. High heat-transfer coefficient and high turbulence due to even flow distribution are important. However, a plate heat exchanger regenerator is restricted to low viscosities.
Should I turn my air exchanger off in the winter?
In winter, set the dehumidistat just low enough to prevent condensation on windows. Do not shut off or unplug your HRV. This can result in high humidity levels, which can lead to mould and mildew growth and unhealthy living conditions.
Should my air exchanger run all the time?
Air exchangers should be run at all time, summer and winter. Depending on the size of your home, energy-efficient air exchangers can cycle through all the air in your home in just a few hours.
