The dew condensed on solidifying coil pipe.
In the present invention, the structure of dehumidification system is mainly by air conducting part 6 and the surface air cooler condensed to air
7.When air-conditioning requests to freeze, refrigerant is flowed out from air-conditioning refrigeration plant, is sufficiently carried out heat exchange in radiation cooling device and is taken away room
It is returned again after interior heat and flows into air-conditioning refrigeration plant.It is configured with refrigerant circulation driving device in entire refrigeration system, is reinforced cold
Matchmaker's flow circuit.In the present invention radiation cooling device may be arranged in building closed structure any position as the top in room,
On the wall in face and room, the temperature in room is reduced by way of radiation refrigeration.
The present invention is also easy to produce dew condensation phenomenon for radiation refrigeration and devises dehumidification system.The dehumidification system may be arranged at window
Closed structure in mouth, wall, ground or the building of other any need dehumidifying.Dehumidification structure is broadly divided into two parts: air
Water diversion part 6 and surface air cooler 7.
Air conducting part 6 is mainly made of magnetic coupling 8 and fan 9, and the high temperature and humidity air entered the room passes through
The water conservancy diversion of 8 driving fan 9 of magnetic coupling first flows through surface air cooler and is condensed.The power of magnetic coupling in the present invention comes
Refrigerant kinetic energy in refrigerant outflow main line 3.Refrigerant kinetic energy passes through power intake, that is, copper rotor 10 of magnetic coupling 8

Risk.
It is illustrated in figure 3 the control rule of the dehumidification system in the present invention.The control rule be suitable for power-on of air conditioner until
Power-down phase, referred to as one control period.Next power up cycle continues cycling through control rule.
The dehumidification system is divided into manual mode and automatic mode, and priority is manually controlled within a control period and is higher than certainly
Dynamic control.Specific control rule is as follows:
Power-on of air conditioner is run in room, and air-conditioning system passes through the parameter monitoring of the settings such as temperature and humidity or door and window magnetic switch
Whether ventilation window is opened:
If do not opened window, then air-conditioning normal operation is not turned on dehumidification system.Air-conditioner control system persistently receives user
The no signal for opening dehumidification system, such as the manually opened dehumidification system of user, then dehumidifying brings into operation, until user is turned off manually and removes
Wet system or air-conditioning power-off terminate this cycle of operation.
Such as detect that ventilation window is opened, then air-conditioning system automatically turns on dehumidification system.Air-conditioner control system persistently receives
Whether user closes the signal of dehumidification system, the dehumidification system continuous service if user is to close dehumidification system.As user is manual
Dehumidification system is closed, then is dehumidified out of service, until user reopens dehumidification system manually.
The revolving speed of fan depends on refrigerant flow rate in refrigerant outflow main line in dehumidification structure.When air conditioner refrigerating load increases
Greatly, condensation risk can increase therewith, and the flow velocity in refrigerant pipeline also will increase at this time, and rotation speed of the fan night can rise with it, on the contrary
Air conditioner refrigerating load reduces, and condensation risk can decrease, and the flow velocity in refrigerant pipeline can also reduce at this time, and rotation speed of the fan also can
Decline therewith.
