Embodiment two：The control method of air-conditioning humiture decoupled system
The control method of a kind of air-conditioning humiture decoupled system in the present embodiment, for indoor epidemic disaster in setting
In the range of regulation is controlled to indoor epidemic disaster, methods described specifically includes following steps：
(1) setting value (such as 65%) of return air relative humidity is given in valve control module, is given in fan control module
The setting value (such as 25 DEG C) of return air temperature.When air conditioning terminal is run, air switch 14 is closed in switch board 13, and blower fan 3 is normally transported
OK, the output control signal of valve control module 15 opens the water outlet pipe end on the electric T-shaped valve 10 on coil pipe outlet pipe 8, bypass
The valve of pipe 9 is closed, and water pump 6 postpones to start for 1 minute after receiving the control signal of the output of water pump control modules 17, each part work in end
Make, realize the normal air-supply of air-conditioned room.
(2) valve control module 15 receives the real-time relative humidity for the return air inlet for air-conditioner 4 that air port humidity sensor 11 gathers
Signal, compared with RH set point, electrically operated valve opening amount signal is obtained, valve control module 15 exports electrically operated valve and opened
Spend signal, so as to control electric T-shaped valve 10 bypass pipe end aperture, hundred and change the water-in and water-out temperature of coil pipe.When return air
Relative humidity is entered less than setting value 65%, and the output control signal of valve control module 15 makes electric T-shaped valve 10 bypass opening for pipe end
Degree becomes big, and the water outlet of coil pipe 2 flows into water inlet pipe 7, the rise of the water temperature of water inlet pipe 7 from bypass pipe 9, and moisture removal reduces, and (room is empty for return air
Gas) relative humidity be increased to setting value, now pass through the water circulation of coil pipe, coil pipe leaving water temperature rise, into evaporator
Water temperature rise, the efficiency of refrigeration machine can be improved；When the relative humidity of return air is higher than setting value 65%, valve control module
15 output control signals make the aperture of the bypass pipe end of electric T-shaped valve 10 diminish, and the flow of bypass pipe 9 reduces, the water inlet pipe 7 of coil pipe 2
Water temperature reduces, and moisture removal increase, the relative humidity of return air (space air) is reduced to setting value.
(3) fan control module 16 receives the real time temperature for the return air inlet for air-conditioner 4 that temperature sensor 12 gathers, and is set with temperature
Definite value compares, and obtains the operating frequency signal of blower fan, the output frequency signal of fan control module 16, is adjusted by fan frequency converter 18
Fan operation frequency is saved, so as to maintain return air temperature in setting value；Carrying out practically process is：When return air temperature is less than setting value 25
DEG C when, fan control module 16 export frequency variation signal pass through fan frequency converter 19 reduce blower fan 3 running frequency, room air output
Reduce, fan energy consumption reduces；When return air temperature is higher than setting value, fan control module 16 exports frequency variation signal and become by blower fan
Frequency device 19 improves the running frequency of blower fan 3, increases the air output of air conditioning terminal, and return air temperature is reduced to setting value, maintains return air
Mouth temperature is constant, and then ensures the thermal comfort requirement in room.
In the control method of the air-conditioning humiture decoupled system of the present invention, valve control module and fan control module are same
When output control signal control electrically operated valve aperture and fan operation frequency, further maintain the epidemic disaster of air conditioning terminal return air
It is constant, uneoupled control is realized, ensures the operation of the efficient stable of system.When system is out of service, terminal water pump is out of service,
Electric three passes valve is closed, and blower fan is out of service.
On the one hand air-conditioning epidemic disaster decoupled system provided by the invention can be very good to realize the epidemic disaster of air-conditioned room
Phase control is solved, improves the thermal comfort in room；On the other hand, this system utilizes electric T-shaped valve and frequency conversion fan control end disk
The water-in and water-out temperature and air output of pipe, so maintain room relative humidity and temperature it is constant, it is simple in construction, without again
Heat, avoid unnecessary energy dissipation；And reduce in space moisture load, go out water temperature by what the water circulation of coil pipe made coil pipe
Degree rise, the water temperature into evaporator raise, and can improve the efficiency of refrigeration machine；Control method provided by the invention can basis
The relative humidity of end return air and the aperture of temperature control electric T-shaped valve and the converting operation of blower fan, realize that control is automatic
Change, ensure that the efficient of system with stably.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
