Cooling and dehumidifying system for electric control cabinet of leaf storage room

Abstract

The invention discloses a leaf storage room electric control cabinet cooling and dehumidifying system, and relates to the technical field of tobacco storage electrics, in particular to the electric control cabinet cooling and dehumidifying system which comprises an air pipe, first filter cotton, a first refrigeration piece, a fan and an air inlet baffle. According to the system, the air inlet baffle is used for adjusting the volume of air entering the electric control cabinet and balancing the air volume among the plurality of electric control cabinets. According to a system control unit, by controlling the opening angle of the air inlet baffle, the air pressure in the power distribution cabinet is higher than the external atmospheric pressure, clean air filtered by the first filter cotton overflows outwards through gaps of the control cabinets, dust cannot enter the electric control cabinets, the cleanliness of the electric control cabinets is guaranteed, and the service life of electrical equipment in the electric control cabinet is prolonged. The system is provided with a second refrigeration piece, the refrigeration piece performs dehumidification operation on the interior of the electric control cabinet in a mode of combining heating and condensation at the same time, the dehumidification efficiency is high, and the system is very suitable for dehumidification operation on the interior of the electric control cabinet after power failure and power transmission.

Description

technical field [0001] The invention relates to the field of electrical technology for tobacco storage, in particular to a cooling and dehumidification system for an electric control cabinet in a leaf storage room. Background technique [0002] In the tobacco production and processing industry, due to the requirements of the process conditions, the humidity range of the storage room in the silk workshop is 60%-75%, and the temperature range is 28°C-32°C. In addition, the dust pollution in the production environment is very serious, so dustproof, moistureproof, and cooling This is the current pain point in the industry. The electric control cabinet itself is equipped with a lot of high-power electrical equipment or components, which will generate a lot of heat during continuous operation (the continuous working time of full load is an average of 16 hours per day). It not only affects the normal operation of electrical equipment, but also accelerates the aging of equipment an...
