Description

The multi-air condition system and its working method dry for grain depot
Technical field
The present invention relates to silo air-conditioning system field, the multi-air condition system and its work dry for grain depot are particularly related to Make method.
Background technique
In recent years, with a series of implementation of Huinong's policies of country, the area for promoting grain large-scale planting, concentrator to receive More and more, peasant sells the wheat newly harvested without drying, and grain depot is increasingly difficult to the quality control of stored grain, The phenomenon that this results in high moisture grain directly to put in storage.For China's most area grain depot, conveying grain into storehouse storage During depositing, grain face temperatures above is influenced in 6,7,8, September part silo space by wall and silo roof illumination heat radiation, empty in storehouse Between temperature can continue increase, cause grain occur keeping difficulty it is big, easily mildew the problems such as, seriously affect grain quality.
Major part grain depot is all using civil air conditioner to the above air cooling-down of grain face at present, but by civil air conditioner Design, manufacture characteristic be easy to cause phosphine gas to the heavy corrosion of A/C evaporator and circuit part, enter and leave grain Shi Fenchen The factors such as dehydration, high, the maintenance inconvenience of energy consumption cause service life very short when contamination and plugging heat exchanger and filter screen, strainer, grain Phenomenon.
And existing air-conditioning is placed directly into silo, and directly operation after temperature, Bu Nengyou are then set Effect carries out zonal control to silo according to factors such as temperature, humidity in silo, it is also necessary to control respectively to each air-conditioning System, inconvenient for use, it is bad that grain stores effect.In order to guarantee the safe storage of grain, it is necessary to be carried out to it at appropriate drying Reason, and existing drying means such as carry out drying using dryer and need to consume a large amount of fossil energy, at high cost, and natural Aeration-drying, time-consuming, big by external environment inside even from weather.Condensation method removal moisture drying technology, although being also able to satisfy grain It is dry require, but equipment operating cost is higher, the low efficiency in high humidity, Wind Volume, and inconvenience etc. is drained in operation and is asked Topic.
Summary of the invention
The present invention proposes a kind of multi-air condition system and its working method for grain depot drying, solves and utilizes the sun The technical issues of energy double stage heat pump runner system rapid draing high-moisture silo.
The technical scheme of the present invention is realized as follows:
