2014年3月8日 · FAHU : Fresh Air Handling Unit, same as a AHU but dosent have air recirculation option(100% Fresh Air is used). The Return air is extracted to the atmosphere either used Heat Wheel or coils like heat exchanger coil,pre cooling coil and cooling coil with pre filter, bag filter,UV lamp,HEPA filter,Carbon filter { where it is applicable }and for ...

FAHU (Fresh Air Handling Unit): It handles total fresh air (no return air). Generally takes air from atmosphere & cools down it to less temperature, which can then be supplied into common areas / AHU / any other area as per design requirement.

2017年1月19日 · fahu : is air ahu deal with fresh air only. TFA : TREATED FRESH AIR. HRW : IS AN INSTRUMENT TO SAVE ENERGY BY MAKING CONTACT BETWEEN EXHAUSTED AIR AND FRESH AIR ACROSS CONTACT SURFACE WITHOUT.

2015年1月17日 · * for accurate temperature calculate the load for the FAHU as normal AHU supply & return, then find out the return temperature after living the zone which indicated on the psychometric chart, then use it as the inlet temperature for the energy wheel

2015年6月29日 · The FAHU is sized based on the indoor fresh air requirements in cfm or l/s referring Ashrae indoor air quality standards, The sensible heat and upto the extent the latent heat shall also be removed from the incoming fresh air containing huge load, such that the supply air from the FAHU have a design criteria of 24 degree C and may be 70% RH by ...

2016年9月17日 · FAHU Recovery wheel using to cool fresh air from out side high temperature to lower temperature using cold rejected exhaust air from inside building to outside so can utilize the cold air and finally reach to power conservation . by an other way can say its uses to reduce FAHU (DELTA T) THEN cooling capacity of FAHU.

2015年12月6日 · AHU is basically provides cool air with no fresh air and FAHU provides fresh cool air which is supplied to various FCU and AHU'S. Upvote (0) Downvote Reply ( ) Report

What is the difference between FCU,AHU,FAHU in hvac? Electrical HVAC Design.

2013年4月18日 · fahu is used to conserve energy by interchanging the enthalpy of the air coming from corresponding higher or lower temperature regions of the building

2015年8月27日 · usually for FAHU one ton =toCFM take it asCFM that means total cooling load is around.5ton. for sensible load take outdoor temp. as.8F and the outlet temp..4F then ∆T air =.4F. the sensible heat will beBTU/HR =.1MBTU/HR which equal.ton
