(2) working principle of said set

1st, the operating mode (providing two kinds as an example) of the unit

1.1st, summer operation pattern

1) user sets systematic parameter (self-cleaning period distances, air quantity, Threshold of Temperature And Humidity, day on a touch-screen display first The functional modes such as phase, timed power on/off, manual switch machine are set)

2) after starting shooting, two Fans start, the operating of enthalpy wheel, cohesion sterilizing unit work, temperature, humidity, CO₂, PM2.5 pass Sensor starts at the same time.

3) outdoor air is sucked in unit under the action of wind turbine, can kills in air and be taken by cohesion sterilisating section 21 The virus of band, bacterium, then by complex filter 23, the particles such as >=5 μm of dust are filtered out in air.

4) differential pressure pickup 20 can detect the pressure differential before and after complex filter 23, and be converted into electric signal and feed back to electricity Source control module 7.When pressure differential is larger, energy supply control module 7 receives the electric signal from differential pressure pickup 20, starts certainly Clean device 22, cleans composite screen.When pressure recovers normal operating conditions before and after composite screen, self-cleaning device 22 stops Work, while can also control the startup and closing of self-cleaning device 22 manually on a touch-screen display.Self-cleaning device can also be according to Self-cleaning period distances, periodically clean composite screen.

5) fresh air carries out energy exchange after composite screen enters enthalpy wheel with indoor exhaust wind, recycles entrained by indoor exhaust wind Cold (heat).

6) indoor return air is mixed in mixing section latter with entering high efficiency particulate air filter after medium effeciency filter with fresh air, high Effect filter can filter out in air the microparticles such as >=0.4 μm of dust.

7) when the indoor humidity that the humidity sensor 18 at indoor return air mouth 12 detects exceedes threshold value, dehumidifying switching valve 8 is beaten Open, high efficiency filter section is connected with dehumidifying section, meanwhile, water dispenser starts, working medium output control valve 1, working medium reflux in electromagnetic valve Control valve 2, cold water output control valve 5, cold-water reflux control valve 6 are opened, and cold water is provided for dehumidifier.

8) air after dehumidifying enters Exposure degree section, and Exposure degree section will enter fresh air (before dehumidifying) and the dehumidifying of unit Fresh air afterwards carries out energy exchange, and air themperature after lifting dehumidifying, interior is sent into after air dewetting by air-introduced machine 9.

9) when the indoor humidity that the humidity sensor 18 at indoor return air mouth 12 detects drops to preset value, dehumidify switching valve 8 close, and high efficiency filter section is directly connected with 9 region of air-introduced machine, meanwhile, water dispenser is stopped, and above-mentioned electromagnetic valve closes Close, dehumidifying section, the work of Exposure degree section stop, other modules run well.

10) in dehumidification process, 9 air outlet temperature of air-introduced machine that temperature sensor 16 detects at indoor air outlet 11 exceeds threshold When being worth scope (22~26 DEG C), then air outlet temperature is adjusted by the water flow of water dispenser control injection dehumidifying section.

1.2nd, winter operating mode

Winter operating mode is identical in step 1-6 with summer operation pattern.Difference lies under winter operating mode, remove for it Wet switching valve 8 is closed, and water dispenser is opened, working medium output control valve 1, working medium recycle control valve 2, hot water output control in electromagnetic valve Valve 3, hot water return control valve 4 are opened, and hot water is provided for heater, to lift 9 air outlet temperature of air-introduced machine.

2nd, operation and control

User can realize unit according to indoor actual conditions following individually control：

1) Boiler pressure control (high, medium and low more gear controls) of wind turbine.

2) startup and closing of self-cleaning device.

3) air outlet heating module opens and closes.

4) open and close of dehumidifying switching valve, dehumidification function starts after unlatching, and air is sent under fan action after closing Enter indoor (dehumidification function closing).

The advantage of this Fresh air handling units be exactly with primary retirn air structure make full use of room air with heat (cold), Part is purified at the same time and can reduce indoor accelerated test concentration.And the section that dehumidifies has heat recovering device, maximally utilizes room The heat of interior air and the air of dehumidifying section carry out energy exchange, avoid conventional dehumidification function and also need additionally to increase heating and set It is standby, there is good economy and energy saving, comfort.
