Background technique

In recent years, the temperature has continued to rise, and many outdoor workers are facing the double test of high temperature and sunlight. With the improvement of national safety awareness, people have higher and higher requirements for their own occupation and working environment when working . Environmental temperature is closely related to human health. Generally speaking, the best environmental temperature that the human body can adapt to is between 20°C and 28°C. When the temperature rises, a series of physiological function changes will occur in the human body, especially when exposed to high temperatures for a long time. In the environment of 35 ℃, it can even cause physical lesions. Therefore, improving the working environment of outdoor workers is an important and meaningful work.

Many outdoor jobs, such as rail transit command desks, gas station workers, etc., cannot take effective, energy-saving and economical ventilation and cooling measures due to the particularity of their positions in open spaces. As an energy-saving and environmentally friendly technology, evaporative cooling technology has been widely used in our country, but for some outdoor jobs, such as those that require fixed-point cooling, there are still few types of unit evaporative cooling air conditioners and there are many types. Big room for improvement.

Nowadays, the common unit evaporative cooling air conditioners are mostly side outlet, and the service object is the public. This form of air conditioning equipment cannot supply air to some people working outdoors, and it does not meet the requirements of small air supply distance and adjustable air volume, wind direction or temperature. , that is, "personalized" air supply and other requirements, not the real sense of station air supply.

Based on the above analysis, a unit-type evaporative cooling air conditioner suitable for outdoor jobs is proposed to improve the working environment of outdoor workers.
