Water cycle process: out water enters in storage tank from damping device, and then under the suction of booster pump, current are sent into accelerating jetting in humidifying spraying nozzle by booster pump after water filter, air is added wet process; When the water-level gauge in storage tank drops to when setting value, will be by filling pipe to moisturizing in storage tank.
After the present invention adopts such scheme, has following obvious effect.
(1) load adaptability is strong.When the external world or room air load changes, the micro-control electronic valve will be regulated its aperture automatically according to the signal of default value and temperature, humidity sensor, and temperature, humidity are remained in accuracy rating.
(2) control accuracy is high.In general, for the control accuracy of temperature can reach ± 0.2 ℃, the control accuracy of humidity is ± 1%.
(3) energy-conservation and good economy performance.Replace compressor and heat(ing) coil because the present invention adopts air compressor machine, film dehumidifying component and vortex tube, reduced greatly the energy consumption of system, extended the service life of system.
(4) seasonal energy efficiency ratio (seer) is high.The present invention can make a response fast according to the variation of Various Seasonal air condition, judges whether air needs the whether lifting of dehumidifying and temperature, in time adjusts the micro-control electronic valve, reduces the energy consumption of air compressor machine and blower fan.
(5) applied widely, the operating mode good stability.Control accuracy of the present invention is high, and it is not only under applicable conventional occasion, and applicable too to those temperature, occasion that humidity requirement is high, is particularly useful for experimental study.Simultaneously, when load is undergone mutation, there is no the impact of compressor and heat(ing) coil because of system,, therefore system response is rapid and operating mode is stable, do not had retardance.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
