Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

This controller is made up of a cover hermetically sealed compressor group, air outlet, air channel and return air inlet, the air that freezes or heat is delivered to each position in the fog room, got back in the unit by return air inlet by air outlet and air channel, circulation makes fog room reach the temperature of standard code repeatedly, ultrasonic humidifier, standby reserve tank (water level control) are formed humidification system, by computer control, its principle is as follows:

Process of refrigerastion: because the variation of ambient temperature, when the maintenance indoor temperature is elevated to 21 ℃, at this moment Temperature Humidity Sensor 10-is 21 ℃ temperature signal, pass to the automatic control flow 4 of micro computer, and notify compressor 2 and centrifugal fan 7 to bring into operation, low-temperature low-pressure refrigerant wet steam in evaporator 6 pipes, under the effect of centrifugal fan 7, make the air circulation in the fog room, absorbed (vaporization heat absorption) behind the heat in the fog room, after becoming 2 compressions of saturated gas suction compressor, the high-temperature high-pressure refrigerant gas that produces is discharged, the four-way change-over valve 5 of flowing through, flow into air cooled condenser 1 again, air cooled condenser 1 is discharged heat (condensation heat release), making the high-temperature high-pressure refrigerant condensation of gas is the refrigerant liquid of middle temperature high pressure, through kapillary 3 throttling step-downs is the low-temp low-pressure wet steam, enter heat absorption in evaporator 6 pipes again, become saturated gas, the circulation that goes round and begins again like this descends the maintenance indoor temperature, when temperature is reduced to 20 ℃, Temperature Humidity Sensor 10 passes to the automatic control flow 4 of micro computer to 20 ℃ temperature signal, and notice compressor 2 and centrifugal fan 7 quit work.

Heat process: when the maintenance indoor temperature drops to 19 ℃, at this moment Temperature Humidity Sensor 10 is 19 ℃ temperature signal, pass to the automatic control flow 4 of micro computer, and notify compressor 2 and centrifugal fan 7 to bring into operation, and unlatching four-way change-over valve 5, at this moment because the commutation effect of four-way change-over valve 5, the refrigerant flow direction of whole refrigeration system is with above-mentioned opposite, it emits heat with evaporator 6 (in fact having become condenser), heat on the evaporator 6, after centrifugal fan 7 operation circulations, the heat transferred on the evaporator 6 in fog room, the maintenance indoor temperature is risen, and the heat that air cooled condenser 1 (in fact having become evaporator) absorption chamber is outer is when temperature rises to 20 ℃, at this moment Temperature Humidity Sensor 10,20 ℃ temperature signal is passed to the automatic control flow 4 of micro computer, and notice compressor 2, centrifugal fan 7 and four-way change-over valve 5 quit work.

Humidification: when the maintenance indoor humidity drops to 90% when following, at this moment Temperature Humidity Sensor 10, the moisture signal that is lower than 90%, pass to the automatic control flow 4 of micro computer, start ultrasonic humidifier 8 and centrifugal fan 7, the beginning humidification, the wind that centrifugal fan 7 is sent, by the air channel mist of ultrasonic humidifier is blown in the fog room everywhere by fog exhaust pipe 11, by return air inlet return air, enter centrifugal fan 7 again, being blown in the fog room everywhere by the air secondary of humidification, humidification that goes round and begins again like this and circulation are so the humidity everywhere in the fog room is very even.When the maintenance indoor humidity rises to 90% when above, Temperature Humidity Sensor 10 passes to the automatic control flow 4 of micro computer to the moisture signal more than 90%, and automatic control flow 4 notice ultrasonic humidifiers 8 of micro computer and centrifugal fan 7 quit work.Water level control box 11 plays a part to ultrasonic humidifier constant water level and moisturizing.
