(2) when a shutdown signal is received, the compressor stops → 10 seconds later, the fan stops, and the air valve is closed;
(3) when the air valve is not opened in the starting state, when the unit is started and operates for 7 hours and 50 minutes cumulatively, and the return air humidity is less than or equal to 50 percent, the air valve is opened for 10 minutes and then closed, the circulation is carried out for 8 hours in a period, and the on-off requirement of the wire controller is executed when a wire controller on-off signal is received in the period.
3. The efficient dehumidification system of a suspended ceiling type fresh air dehumidifier as claimed in claim 1, wherein: low-temperature dehumidification control mode:
(1) the compressor of the unit is started and operates for 7 minutes, the TA temperature is memorized, and the TA difference value is calculated after 7 minutes (after 7 minutes, before 7 minutes is subtracted);
(2) when the TA difference value is more than or equal to 0 ℃, the normal operation of the unit is carried out, the current fan rotating speed is reduced by one gear at the temperature of less than-2 ℃, and then the judgment is carried out once every 20 minutes until the fan rotating speed is reduced to the lowest gear;
(3) when the TA difference is less than-4 deg.c, the compressor is stopped, the blower is operated at the lowest rotation speed, and when the TA difference is greater than or equal to 0 deg.c, the compressor is started.
4. The efficient dehumidification system of a suspended ceiling type fresh air dehumidifier as claimed in claim 1, wherein: and (3) a frost-containing dehumidification mode:
(1) when TE temperature is detected to be less than-5 ℃ and the running time of the compressor lasts for more than 20 minutes, the frost accommodating operation is carried out (if the air valve is in an open state, the air valve is forcibly closed); gradually switching the fan to a low wind gear for 7 minutes (the wind gear switching interval is 10 seconds), reducing the rotating speed of 100 again for 5 minutes after 7 minutes on the basis of low wind gear, and when the TE temperature is lower than-10 ℃, stopping the compressor, and operating the fan according to the current rotating speed;
(2) when the TE temperature is more than or equal to 0 ℃, the compressor is started to normally operate, and the air valve is restored to the state before protection.
5. The efficient dehumidification system of a suspended ceiling type fresh air dehumidifier as claimed in claim 1, wherein: high-temperature dehumidification control mode: when the TC temperature is more than or equal to 38 ℃ and more than 35 ℃, the fan forces the high-wind gear to operate, when the TC temperature is more than or equal to 43 ℃, the fan forces the high-wind gear and adds 100 revolutions on the basis of the high wind rotating speed, and when the TC temperature is more than or equal to 48 ℃, the fan forces the high-wind gear and adds 200 revolutions on the basis of the high wind rotating speed.
