technical field

The invention relates to the technical field of electrical equipment rooms, in particular to a temperature control system for electrical equipment rooms.

Background technique

With the development of new energy technology, various types of high-power electrical equipment are used more and more. And this kind of electrical equipment has extremely high requirements for the working environment. For example, when the ambient temperature is high and the equipment is in full power working state, it generates a lot of heat and needs air conditioning equipment to cool it down; and when it is in a low environment When the temperature is high and the power is low, the air conditioner is required to heat it to make it work in a suitable temperature range to ensure its stability and life. In addition, when there are many such devices and the electrical equipment room where they are located has a large space, it is required that the temperature uniformity in the electrical equipment room be high.

In order to meet the above requirements, the existing technical solution is to install an air duct on the top of the electrical equipment room, and use the air conditioner to send air at a suitable temperature to all corners of the electrical equipment room through the air duct to ensure that the internal temperature is appropriate and uniform. .

However, the above-mentioned solutions can only control the temperature and uniformity of the electrical equipment room in low-altitude temperate or tropical regions; while for environments with low temperatures in high-altitude and cold regions, the heating efficiency of the air conditioner may be too low or cannot be controlled. The hot situation makes it impossible to use existing equipment for heating. At the same time, if the heat storage device is used to heat the electrical equipment room, the existing air-conditioning duct cannot evenly distribute the air volume output by the heat storage device in the electrical equipment room, that is, the uniformity of the ambient temperature inside the electrical equipment room cannot be guaranteed.
