The Air-to-Air Heat Exchangers use exhaust air to pre-condition incoming air to reduce cooling or heating demand and the overall size of the air conditioning system. This improves the energy efficiency of the building and can also help to comply with buildings regulations. Air-to-Air Heat Exchanger Air-to-Air Cross Flow Flat Plate Heat ExchangersThe other airstream is the fresh outdoor air being supplied to the ventilated space. The air in this airstream upstream of the exchanger is called outdoor air. On the opposite end of the exchanger, the fresh air flowing out is called supply air because it is supplied to the ventilated space.
Jul 30, 2019 · An air-to-air heat exchanger brings two air streams of different temperatures into thermal contact, transferring heat from the exhausting inside air to incoming outside air during the heating season. In summer, the heat exchanger can cool and in some cases, dehumidify the hot outside air passing through it and into the house for ventilation. The air-to-air heat exchanger removes the excess HVAC Heat Exchangers Explained - The Engineering MindsetSep 15, 2018 · Duct plate heat exchangers are used in Air handling units to exchange thermal energy between the intake and exhaust air streams without moisture being transferred and without air streams being mixed. The heat exchanger is made from thin sheets of metal typically aluminium, with the two fluids of different temperatures flowing in opposite diagonal directions.
Oct 01, 2018 · In HVAC systems, air-to-air plate-fin heat exchangers (PFHEs) can be used as heat recovery devices to reduce the building energy consumption. The plate-fin heat exchanger (PFHE) is a compact heat exchanger that consists of a stack of alternating plates called parting sheets, and fins brazed together as a block,. Plate Heat Exchangers Hoval - Innergy TechIn the Hoval plate heat exchanger the warm extract air and the cool fresh air, separated by thin plates, pass each other in cross-flow. No mixing of the two air streams takes place. Therefore, the transmission of dirt, odours, moisture, bacteria, etc. is impossible. Heat is transmitted from extract air to fresh air purely by conduction as a result of
