Ion Adsorption Type Total Heat Exchanger Rotor To enhance real I.A.Q. with Ion Exchange Resin as most advanced synthetic desiccantIon Adsorption Type Total Heat ExchangerTotal Heat Exchanger is the energy saving equipment that minimizes the enthalpy heat loss in ventilation and introduces fresh air into the building with high-energy recovery efficiency.Function of Total Heat ExchangerWorking Principle of Total Heat Exchanger Rotor CASING ROTOR SEALING RUBBER DUCT (Cool ・Dry)(Pre-heating・ Humidification) (Pre-cooling・ De humidification)(Hot・We t)Fig.2 BOTH HEAT & MOISTURE TRANSFER THROUGH HONEYCOMBAdvantages of Total Heat Exchanger Rotor To recover not only sensible heat but also latent heat energy. To supply sufficient fresh air to the building with less energy for air-conditioning. To provide the comfortable condition to the human-beings in the buildings. Especially effective in energy-saving for long summer season area like South East Asia.Examples for Saving Energy07:30 ~ 17:30 10hoursOperating timeSummer : 32.6deg C 70%RH 88.70kJ/kg Winter : 1.0deg C 50%RH 3.77kJ/kgAmbient ConditionSummer : 26deg C, 50%RH 52.95kJ/kg Winter : 22deg C, 50%RH 42.90kJ/kgRoom ConditionOA/EA = 41,000/30,000=1.37Flow raito30,000CMH （500CMM ）Exhaust Air 41,000CMH （683CMM ）Outside Air Fuel (Heavy Oil) : JPY83/Litter JPY 2.41/1000Kj Heating Electric rate : JPY23/kWh , JPY2.56/1,000Kj(with calculation based upon COP = 2.5)CoolingMedium Scale Commercial Bldg, Tokyo Japan (8,000m 2)Place Design Condition （Commercial Building ）1)Selection of HI-PANEX PAC-2900T x 1 set(From the performance chart in Catalogue)140Pa82%2.80m/sExhaust Air200Pa62％3.85m/s Supply Air Pressure LossTotal Heat Exchange EfficiencyFace Velocity <Features>2) Savings of Running costa)Annual Ambient Load (calculated by Japan HVAC committee)Summer 18,500 （Kj ・CMH ・<10hrs/day, 3.5months = Annual Operation>）Winter 51,000 （Kj ・CMH ・< 10hrs/day,5.0months =Annual Operation>）b)Annual Ambient Load in 41,000CMH （683CMM ）/OA-SA Summer 41,000×18,500 = 758,500,000（Kj/Annual Operation ）Winter 41,000×51,000 =2,091,000,000（Kj/Annual Operation ）c)Annual Electric power /Fuel for cooling/heating of supplied ambient air Summer 758,500,000Kj/Annual x JPY2.56/1000Kj = JPY 1,941,760.-Winter 2,091,000,000Kj/Annual x JPY2.41/1000Kj =JPY 5,047,674.-d) Saving by operation of HI-PANEX Summer JPY 1,941,760 x 0.62 = JPY 1,203,891Winter JPY 5,047,674 x 0.62= JPY 3,129,558TotalJPY 4,333,449.-(Approx NTD 1.14million)e)Energy Increment by operation cost of Hi-Panex13.4kW0.4kW5.5kW7.5kW Power Consumption TotalGear Motor For Rotor Exhaust FanSupply Fan Summer 13.4kW x 3.5months x 30days x 10H = 14,070kWh Winter 13.4kW x 5.0months x 30days x 10H = 20,100kWhTotal （14,070+20,100) x JPY23/kWh = JPY785,910Total Operation Cost Saving<d) Saving –e) Increment>JPY 4,333,449－JPY785,910 ＝JPY3,547,539/Year(Approx.

Odor molecules are adsorbed together with water molecules into the micro pores of silica gel.Silica Gel○Water Molecule●Odor MoleculeWhy Cross contamination Takes Place by Adsorption-(2) When sudden high moisture condition happens, odor molecules are replaced with water molecule inside micro pores because of strong hydrophilic characteristic of Silica Gel. Odor molecule is transferred from RA-EA side to OA-SA side of Rotor.Casing Rotor Air SealDuct（Wet）rotateRASAEAOAConventional THE rotorOdor is always circulated inside the room.Review & Clue for SolutionThough Silica Gel has very high adsorbability of water molecules, odor molecules are also adsorbed together.Molecular Sieve (zeolite, 沸石) is able to sieve (select) the water molecule among others, though odor molecules similar to water are still adsorbed (like Ammonia ) and its adsorbability of water molecule is limited and lower than Silica Gel.Molecular Sieve Type A Molecular Sieve Type XMolecular SievesBest SolutionWhile maintaining High Latent Heat Recovery Efficiency, cross contamination by adsorption of odor should be resolved byION EXCHANGE RESIN as the BEST DESICCANT for Total Heat Exchanger RotorAdsorption by silica gelAdsorption by IonAdsorption Mechanism of Ion Exchange Resin & Silica GelAdsorption by Ion Exchange ResinHigh polarity water molecule is selectively and electrically attracted by Ion+ or Ion-Water molecule is adsorbed into the inside of resin by hydration with osmosis pressureOdor molecules are relatively low polarity molecules compared to water molecule.
