Almost no cross contamination. Central Station Air Handler 1100 m3/h to 108,000 m3/h. • The recovery wheel operates at a face velocity of 510 ft/min to achieve 75% recovery efficiency • The wheel area per side is therefore 8.8 square feet (17.6 square feet for the total wheel) • The volume of the wheel is then calculated from the face area 17.6 square feet multiplied times the depth .5 feet which equals 8.8 cubic feet If the outside air is too cool to bring into the space yet not economical to heat then the dischargeair can be used to temper the incoming air throughthe heat wheel. Thereafter the energy saving is pure profit in the years to come. Additionally, in the summer it removes heat from the air that is used for economizer and minimum outside air. The all in one AHU and heat recovery unit saves energy by recovering heat. The effectiveness of energy transfer has improved as energy wheel technology has improved. Heat that would otherwise be vented outside in the winter time. HEAT RECOVERY WHEEL AND FILTER 4. The heat transfer matrix is contained in patented energy transfer segments that can be removed from the wheel without using tools. FAHU / ERU with Enthalpy Recovery Wheel and Sensible Heat Wheel FAHU / ERU with Enthalpy Recovery Wheel and Horse Shoe Heat Pipe. FAHU heat recovery function fresh air handling unit manufacturers, You can get more details about from mobile site on m.alibaba.com $3,000.00 Min. A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of an air-handling system or in the exhaust gases of an industrial process, in order to recover the heat energy. As rule of thumb, the additional costs of the second thermal wheel can be saved during the first 6 months. Total energy recovery, recovers both latent and sensible energy. Over 80% energy recovery, both latent and sensible. [Carroll, 1995] More: Heat wheel … Also referred to as a unit . Energy Recovery Units Units can be configured based on the Type of Heat Recovery: FAHU / ERU with Enthalpy Recovery Wheel and Sensible Heat Wheel; FAHU / ERU with Enthalpy Recovery Wheel and Horse Shoe Heat Pipe. The control of operation shall cover following parts of the HVAC system: Supply Side of AHU Usually centralized units employed to induce fresh air quantities to the confines spaces. face air speed is 5.5m/s, the best face air speed is 3.5m/s Rotary heat exchanger is composed of alveolate heat wheel, case, drive system and sealing parts. face air speed is 4.0m/s, the best face air speed is 3.5m/s--Rotary wheel heat recovery: max. recovery wheel. Molecular sieve coated Heat Wheels. • Segmented Media • Low to Zero Deflection Spokes • High Strength Rims • Patented rim connection system eliminates media failures • Tapered Roller Bearings L-10 life 1,000,000 hours With a heat recovery wheel and this selective adsorption feature, cross-contamination has been virtually eliminated. Example 1: Calculate the supply air conditions leav-ing a total heat recovery wheel with 12,000 cfm of outside air at 94°Fdb and 77°Fwb; and 12,000 cfm of return air at 75°Fdb and 50% RH, if both the sensible & latent effectiveness of the wheel is 60%. Enthalpy heat recovery wheel type fresh air handling unit FAHU for HVAC system, US $ 6666 - 6666 / Unit, New, Air Handling Unit, Beijing, China.Source from Beijing Holtop Artificial Environment Technology Co., Ltd. on Alibaba.com. Fig.2 FAHU with Heat Recovery wheel Fig.3 AHU with Heat Recovery wheel. Calculate the reduction in required cooling energy. a) Reduce energy use (psychrometrics of EA energy recovery) b) Comply with energy codes (ASHRAE Standard 90.1, IECC) c) Review the definition of effectiveness Discuss common technologies (advantages & drawbacks, typical performance) a) Coil loop b) Heat pipe c) Fixed-plate heat exchanger d) Fixed-membrane heat exchanger e) Total-energy wheel The molecular sieve heat wheel recovers latent energy and limits cross-contamination to less than 0.04 percent by particulate count. HVAC Heat Recovery Fahu HEPA picture from Guangdong Head-Power Air Conditioning Co., Ltd. view photo of Ahu, Fahu, Heat Recovery Ahu.Contact China Suppliers for More Products and Price. There are 10 key reliability areas to take into account when selecting a heat recovery wheel. FAHU With Recovery Wheel FAHU is the abbreviation used for FRESH AIR HANDLING UNIT.
