Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and detailed description.

A kind of domestic air of the utility model handles unit, as shown in Figure 1, including shell 1, distinguishes on 1 two sidewalls of shell Offer import wind 2 and air outlet 3, be provided with pressure fan 4 at the air outlet 3 of shell 1, in shell 1 along air-flow direction according to It is secondary to be provided with first filter 5, the second filter 6, heat regenerator 7, electric heater 8, direct evaporative cooler 9 and sterilamp 10；Heat regenerator 7 is connected with controller 11 by conducting wire, controller 11 by conducting wire respectively with electric heater 8, directly evaporate it is cold But device 9, sterilamp 10 and pressure fan 4 connect.

First filter 5 is medium effeciency filter or high efficiency particulate air filter, and medium effeciency filter is bag filter or non-pocket type mistake Filter.

Second filter 6 is active carbon filter.

Heat regenerator 7 includes heat exchanger 12, is respectively arranged with exhaust outlet 13 and return air inlet 14, and air draft on 1 wall of shell Mouth 13 and return air inlet 14 are located at 12 both ends of heat exchanger, are provided with exhaust blower 15 at the exhaust outlet 13 of shell 1；Exhaust blower 15 It is connect by conducting wire with controller 11.

Direct evaporative cooler 9 includes water tank 16, packing layer 17 and the water distributor 18 from bottom to top set gradually, water tank 16 It is connect by water circulating pump 19 with water distributor 18, water tank 16 is also connected with water replanishing device 20；Water circulating pump 19 and controller 11 are logical Cross conducting wire connection.

Sterilamp 10 is ultraviolet radiator.

The course of work of the domestic air processing unit of the utility model is as follows:

Three kinds of operational modes are realized by the control of controller 11:

Summer operation mode: exhaust blower 15, pressure fan 4, water circulating pump 19 and sterilamp 10 are opened by controller 11, closed Close electric heater 8.Outdoor air first passes through 5 dedusting of first filter by air inlet 2, has using the filtering of the second filter 6 Then poisonous gas absorbs the pre-cooling of return air cooling capacity by heat regenerator 7, enter back into packing layer 17 and water drenching carries out heat and wet treatment, Constant enthalpy cooling is sent into room from air outlet 3 under the effect of pressure fan 4 later after the disinfection of sterilamp 10；Then indoor return air Enter heat exchanger 12 from return air inlet 14 and fresh air is pre-chilled, is finally discharged to outdoor from exhaust outlet 13 under the effect of exhaust blower 15.

Transition season operational mode: pressure fan 4, sterilamp 10 are opened by controller 11, close exhaust blower 15, recirculated water Pump 19 and electric heater 8；Outdoor air is by first successively 5 dedusting of first filter, 6 filtering poisonous of the second filter of air inlet 2 Property gas, heat regenerator 7 and packing layer 17, using sterilamp 10 sterilize after, pressure fan 4 effect under from air outlet 3 be sent into Room；Then direct draught by door and window is discharged to outdoor to indoor return air indoors.

Winter operation mode: exhaust blower 15, pressure fan 4, electric heater 8 and sterilamp 10 are opened by controller 11, closed Closed loop water pump 19.Outdoor air is by first successively 5 dedusting of first filter, 6 filtering poisonous gas of the second filter of air inlet 2 Body absorbs the preheating of return air heat using heat regenerator 7, is heated to room temperature, then sterilized lamp 10 by heater 8 later After disinfection, room is sent into from air outlet 3 under the effect of pressure fan 4；Then indoor return air enters heat exchanger by return air inlet 14 After 12 preheating fresh airs, outdoor is discharged to from exhaust outlet 13 under the effect of exhaust blower 15.

In the above manner, the domestic air of the utility model handles unit, removed by middle high efficiency particulate air filter outdoor empty Gas dust, active carbon filter remove outdoor air pernicious gas, can effectively prevent outdoor pollutant and enter the room；This is practical new The domestic air of type handles unit, the cold and hot amount of indoor return air can be recycled by heat recovery apparatus, while removing pollutant Comfortable temperature is provided for interior；The domestic air of the utility model handles unit, passes through electric heater, direct evaporating-cooling Device is not only able to achieve winter heating outdoor air, but also in summer cooling and can purify outdoor air, and pass through controller and control Transition season mode, winter mode and summer mode are completed, is offered convenience for people.
