A ventilation and dehumidification system and method for huikong cabinet

Abstract

The invention discloses a control cabinet ventilation and dehumidification system and a method thereof. The control cabinet ventilation and dehumidification system comprises a control cabinet and an air conditioner unit. An exhaust fan is arranged at the top of the control cabinet. The two sides of the control cabinet are provided with rainproof shutters. A self-hanging shutter capable of being opened inwards is additionally installed on the inner side of each rainproof shutter. An air supply duct of the air conditioner unit enters the control cabinet from the bottom of the control cabinet and extends upwards to the upper portion of the control cabinet. An air supply opening is formed in the upper portion of the air supply duct. An air return opening is formed in the bottom of the control cabinet. The bottom of the control cabinet is connected to the air conditioner unit through an air return duct. According to the control cabinet ventilation and dehumidification system, the control cabinet is modified, the conventional control cabinet and the conventional air conditioner unit are adopted, the air conditioner unit is connected with the control cabinet through the air supply duct and the air return duct, the self-hanging shutters capable of being opened inwards are installed on the inner sides of the rainproof shutters, a temperature and humidity sensor is arranged inside the control cabinet, and the air conditioner unit and the exhaust fan are automatically controlled in a switching mode according to the temperature and the humidity, so that the running time of an air conditioner compressor is effectively shortened, the heat transfer temperature difference is effectively reduced, and electric resources are greatly saved.

Description

technical field [0001] The invention belongs to the technical field of ventilation and air conditioning, and relates to a ventilation and dehumidification system and a method thereof, in particular to a ventilation and dehumidification system and a method for a control cabinet. Background technique [0002] With environmental pollution, atmospheric ozone layer destruction, global temperature rise, and at the same time, with the construction of smart grid, there are more and more protection and control components in the control cabinet, and the heat dissipation is increasing, and the control cabinet The requirements for ambient temperature and humidity are getting higher and higher. Except for severe cold and some cold areas, high temperature alarms often occur in the HSBC cabinet when the outdoor temperature is high in summer, and the HSBC cabinet often alarms due to excessive humidity when the outdoor air humidity is high after rain. [0003] In order to meet the environme...

AI Technical Summary

Problems solved by technology

[0004] In order to meet the needs of the development of the power grid, most smart substations have carried out ventilation and dehumidification reforms on the control cabinets. Huge energy consumption, various renovation measures, and unsatisfactory results

There is still no reasonable and advanced method to meet the temperature and humidity conditions required for the operation of the control cabinet in the hot summer or the environment area with large rainfall
