Embodiment Construction
[0018] Such as figure 1 As shown, the present invention includes: a humidity sensor, a humidity control module, a liquid pipeline, a gas pipeline and a nozzle 9, and the humidity control module is a PLC8. The initial end of the liquid pipeline is provided with a water pump 1, the initial end of the gas pipeline is provided with an air compressor 2, and the intersection of the liquid pipeline and the gas pipeline is provided with a nozzle 9; PLC8 is connected to the humidity sensor; PLC8 is connected to the liquid pipe respectively When the humidity signal transmitted by the humidity sensor is lower than or higher than the set value of PLC8, PLC8 controls the opening or closing of the solenoid valve 7 of the liquid pipeline and gas pipeline. The liquid and gas flow to the junction and finally to the nozzle 9 for spraying. The liquid pipeline and the gas pipeline are provided with a filter device 4 , the filter device 4 of the liquid pipeline is arranged between the water pump ...

The invention provides a humidity control device of a test room. The humidity control device of the test room comprises a humidity sensor, a humidity control module, a liquid pipeline, a gas pipeline and a nozzle, wherein a water pump is arranged at an initiating end of the liquid pipeline, an air compressor is arranged at an initiating end of the gas pipeline, the nozzle is arranged at the intersection position of the liquid pipeline and the gas pipeline, the humidity control module is connected with the humidity sensor, and the humidity control module is in connection with magnetic valves of the liquid pipeline and the gas pipeline. When a humidity signal sent by the humidity sensor is smaller than or larger than a set value of the humidity control module, the humidity control module controls opening or closing of the magnetic valves of the liquid pipeline and the gas pipeline, liquid and gas are controlled to flow to the intersection position, and finally the nozzle carries out mist spraying. The humidity control device of the test room has the advantages that through the adoption of the technical scheme, humidity adjustment is uniform, areas controlled by humidity is large, and the humidity control device of the test room has the advantages of being simple in structure, convenient to maintain, low in machining cost, high in humidification efficiency, and the like.
Description
technical field [0001] The invention relates to the field of air humidity control equipment, in particular to a humidity control device for a laboratory. Background technique [0002] In the existing technology, in a general laboratory, many tests need to be carried out in an environment with controlled humidity. Generally, the use of a humidifier in a confined space is simulated in the laboratory for humidification, but once it is in a large-scale laboratory, the humidification capacity of the ordinary humidifier obviously cannot meet the requirements. There are technical problems such as the humidity cannot meet the requirements, and the humidity control is uneven. Contents of the invention [0003] The problem to be solved by the present invention is to provide a humidity control device for a laboratory. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention includes: a humidity sensor, a humidity con...
