Description
Technical field
The present invention relates to a kind of intelligent unit installation and control method, especially a kind of intelligence adjusts the control of indoor environment
Unit processed and control method.
Background technique
New Fan Equipment is widely used in the places such as family, hotel, office building, villa.New blower is due to that can give room
The air of interior supplement fresh air discharge foul indoor, solves air conditioner disease and is widely used in each place, but due to indoor and outdoor temperature
Difference is larger, and fresh air heat exchanger load is with regard to larger waste of energy, although having added total-heat exchanger, can recycle one in summer
Part cooling capacity, but part energy is also wasted, especially in winter, outdoor temperature is very low especially in northern area
Outdoor temperature is lower than subzero 10 degree, it is easy to freeze in total-heat exchanger, and block total-heat exchanger, influence the fortune of Fresh air handling units
Row.
Clarifier solves room air pollution so can be extensive due to being capable of handling the environmental contaminants such as quick PM2.5
It applies among family, especially in north of china in winter, is more widely applied.But the clarifier most of the time in confined space,
In this way if time length, then interior be easy to cause the symptoms such as anoxic, experiences very bad.
CN106440176A, it discloses a kind of energy-saving multifunctional Fresh air handling units, but it only focuses on one parameter of temperature, only
Be solve temperature control and Xingfeng capsule, specific control amount is unknowable, and without purification and oxygen content state modulator, the present invention from
Entire indoor heating system, which sets out, emphasizes indoor multi-parameter intelligent control.What inventive concept of the invention addressed is entire interior
All indoor environment parameters such as temperature, humidity, CO2, PM2.5, especially by the control method of parametrization, according to various parameters
The intelligent closure control for determining each component switches is set, provides optimal comprehensive ambient experience for interior, this is the present invention
One of important inventive point do not find similar application, foregoing invention point is being presently not common knowledge by retrieval.
Inventive point of the invention also resides in: above-mentioned patent reaches after the first air -return duct is mixed with fresh air and is higher than when in winter
The method of the dew-point temperature of total-heat exchanger, is not achieved ideal effect in specific implementation, the present invention be arranged at fresh wind port electricity plus
Heat 1 can be precisely controlled to achieve the desired purpose by the new air temperature of total-heat exchanger；It is above-mentioned special when controlling air outlet temperature
Benefit the second air -return duct of control is reached by the method for mixing return air amount with the fresh air by heat exchanger greatly improves leaving air temp
Purpose, since fresh air will pass through total-heat exchanger, evaporator resistance is very big, most of if opening the second air -return duct at this time
Indoor return air can be made a gift to someone interior by not having resistant air -return duct, then fresh air essentially due to resistance can not make a gift to someone greatly interior；
And the present invention is precisely controlled heating amount according to judgement by electric heating 2 reaches supply air temperature both and can guarantee Temperature Quantity or can guarantee fresh air
Amount, exploitativeness are very strong.
By retrieval, similar application is not found, foregoing invention point can certainly not common knowledge now.
Inventive point of the invention also resides in: although all there are two air returning valve, the works of air returning valve for the present invention and above-mentioned patent
With entirely different.The air returning valve 1 and air returning valve 2 of above-mentioned patent, which act on, to be to adjust the temperature for neutralizing fresh air, and effect is undesirable；
And air returning valve 1 of the present invention with 2 main function of return air is run under the premise of guaranteeing target component according to indoor and outdoor different parameters
For different modes to reach the comfortable purpose of energy conservation, the invention point of the invention and above-mentioned patent have essence difference.
Above-mentioned multiple technologies defect has been solved perfectly in the present invention, can be precisely controlled outdoor fresh air by increasing electric heating 1
Temperature, system caused by avoiding winter temperature too low freeze etc. failures；Wind-warm syndrome can be precisely controlled out by increasing electric heating 2
Degree, which had not only been avoided that caused by leaving air temp is low, blows mist phenomenon, but also can achieve the purpose of control precision.Furthermore the unit device and
Control method can be opened according to detection environment in time by the real-time detection of humidifier, clarifier and various sensors
What is closed cut-offs control, provides optimal ambient experience for interior.A kind of intelligent unit installation and controlling party provided by the invention
Method both can solve the problems such as room temperature, humidity, cleanliness and oxygen content, while also intelligentized control method can be needed to reach according to environment
To Energy Saving Control purpose, solves people to the demand for control of temperature, humidity, ventilation etc., avoid and be in air-conditioning for a long time
It will cause air dirt in room, the problem of the air conditioner diseases such as anoxic.
