The air condition cross flow is the major part of heat recovery ventilator. Because the different temperature between the fresh air and exhaust air, the air is forced to crossover through the air to air core, the heat would transfer from the hotter side to the colder side, so as to recover the energy from exhaust air.Two airstream never come into direct contact,make sure no cross contamination.
