ALUMINIUM CROSSFLOW PLATE HEAT EXCHANGER A cross-flow heat exchanger is used in a cooling and ventilation system that requires heat to be transferred from one airstream to another.The thermal energy is exchanged via the panels. A traditional cross-flow heat exchanger has a square cross-section. It has a thermal efficiency of 4065%.
Heat recovery units are supply and extract systems delivering filtered fresh air into a building whilst extracting stale, stagnant air from the interior. Each unit will have a heat recovery element (thermal wheel, plate heat exchanger or run around coil) that is capable of transferring the heat that would otherwise be lost into the incoming air Commercial Ventilation and Heat Recovery HeatexAn air-to-air heat exchanger will utilize the temperature difference between the supply and exhaust air to increase the overall system efficiency and both recover the waste energy and save a considerable amount of energy usage. Air-to-Air Heat Exchangers There are two types of air-to-air heat exchangers, rotary and plate heat exchangers. Which one is selected depends on a set of parameters.
This exchanger has a liquid coil in the supply air and the extract air. The liquid in the extract air coil is heated by the extract air and is pumped to the supply air coil which heats the supply air. The temperature efficiency is as high as 68% if the supply air and extract air flow at Global Manufacturer Of Air-to-Air Heat Exchangers HeatexHeatex specializes in plate and rotary heat exchangers used in ventilation and thermal management applications worldwide. Global Manufacturer of Air-to-Air Heat Exchangers. Our Products. Indoor Air Quality you will find an air handling unit and within it a perfectly fitted heat exchanger for heat and energy recovery.
The heat exchanger is usually made up of two separate pipes or chambers separated by a wall. Within the unit's ventilation system energy is recovered through this exchange. This contributes to the overall efficiency of the system. Heat exchangers are commonly used in refrigeration systems, space heaters, and air conditioning units. HVAC Heat Exchangers Explained - The Engineering Sep 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.
No cross-contamination of the air streams In 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. Air-to-air heat exchangers & ventilation components ERI Aluminium Crossflow Plate Heat Exchanger. Recuperative heat exchanger, in which the explicit and latent heat is transferred directly from the exhaust air to the supply air through a heat exchanger walls without moisture transfer.
