3, perfect in shape and function.The utility model is on step recuperation of heat loop, system's air draft is not only effectively migrated and is the regeneration wind of desiccant wheel, and the recuperation of heat by two steps of new wind-heat load and exhaust waste heat fully exchanges on the wind of regenerating the regeneration energy consumption when having saved rotary wheel dehumidifying in a large number.Realize that the air draft recuperation of heat combines with dehumidifying regeneration, both reached the purpose of air draft recuperation of heat, improved effect on moisture extraction again.
4, reduced cost.The utility model is done partial heat exchange with the high-temperature exhaust air of desiccant wheel again with system's air draft and is reclaimed, the regeneration wind of back as desiccant wheel heats up, the air draft that temperature is lower enters heat reclamation device, carry out heat exchange with new wind, reclaim the heat in the new wind, reach purpose of energy saving,, have the vast market economic benefit so reduced cost significantly.
5, expanded the frontier of the renewable sources of energy.The utility model provides approach for realizing used heat regeneration, reduces the consumption of electric energy, realizes the sustainable development of the energy.
6, reduced consumer cost.The hot blast that the utility model is discharged air-conditioning carries out the secondary utilization, freezes once more as kinetic energy, has both realized the secondary recovery of the energy, has reduced the power consumption of air-conditioning again, makes the consumer reduce consumer cost simultaneously.
7, environmental protection.The used heat secondary utilization that the utility model will once be discharged has reduced atmosphere pollution, has realized the innovative idea of environmental protection.
8, prolonged service life.The reduction that the utility model is sent into new wind-warm syndrome degree helps reducing the thermic load of air-conditioning system, has reduced the mechanical wear of air-conditioning unit, thereby has prolonged the service life of air-conditioning unit.
The beneficial effects of the utility model realize by following operation principle:
In summer, new wind enters after new wind forecooler tentatively cools off and dehumidify after roughing efficiency air filter filters, and enters desiccant wheel and carries out the degree of depth and dehumidify and carried out a constant-enthalpy process, although humidity has reduced, temperature has also raise.Through degree of depth dehumidifying reach cause the humidity demand after, new wind enters heat reclamation device, carries out heat exchange with the air draft that temperature is lower, reclaims the cold in the air draft, reaches purpose of energy saving.Through handling new wind afterwards like this after new wind blower fan pressurization, again after new wind medium air filtration, send into indoor, mix mutually with same return air through medium air filtration, air after mixing through coil pipe dry and cold reach cause temperature requirements after, by the pressurization of distributing blower fan filtering unit (FFU), the final high efficiency filter of warp is sent into indoor afterwards, to keep the quality requirement of indoor purifying environment.
Air draft after the cooling of water spray equal-enthalpy humidifying, is carried out the recuperation of heat conversion under the effect of regeneration blower fan, under the heating of new wind, temperature has raise.Yet, for the regeneration desiccant wheel, at this moment temperature is also too low, need further to heat up, in order to reduce this part energy consumption, adopt the air behind the rotary wheel regeneration to come the backheat regeneration air, and then through further again after the heat of step, reach the requirement of regeneration wind, thereby play energy-conservation effect.
