The utility model can reach following beneficial effect after adopting technique scheme:
1, reasonable in design, simple.The utility model has been realized combining of device energy conservation and energy saving of system, and whole device is reasonable in design, simple.
2, environmental protection.The utility model is realized the air draft recuperation of heat on improvements over the prior art, reclaim the energy in the air draft, has reduced the discharge wind of air-conditioning, has purified air, helps environmental protection.
3, improved the utilization rate of air-conditioning.The utility model realizes that the air draft recuperation of heat combines with dehumidifying regeneration, has both reached the purpose of air draft recuperation of heat, has improved effect on moisture extraction again.
4, reduced cost.The utility model adopts the heat energy to exhaust to reclaim in order to thermal regeneration wind, thereby saves a large amount of renewable sources of energy, reduces and discharges used heat and reduce operating cost, and the Energy Efficiency Ratio of air-conditioning system is improved greatly.
The beneficial effects of the utility model realize by following operation principle:
In summer, new wind enters new wind forecooler and tentatively cools off and dehumidify after roughing efficiency air filter filters, and enters desiccant wheel again, carries out the degree of depth and dehumidifies.Through degree of depth dehumidifying reach cause the humidity demand after, new wind enters the recuperation of heat runner, 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 after new wind blower fan pressurization, after new wind medium air filtration, send into indoor again, mix mutually with same return air through medium air filtration, air after mixing through coil pipe dry and cold reach cause temperature requirements after, pressurization (also can adopt centralized purification air-supply unit) by 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.
Because desiccant wheel can lose dehumidifying effect after constantly absorbing airborne moisture, therefore must regenerate to desiccant wheel.And the temperature of indoor exhaust wind and water capacity are all low more than outdoor air, if can adopt indoor exhaust wind as regeneration wind, carry out the air draft recuperation of heat simultaneously, the effect that just can play not only energy savings but also improve dehumidification rate.Adopt air draft as regeneration wind in the design, 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, and under the heating of new wind, temperature raises.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, design adopts 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.
