The water spray cooling and energy saving system of the outdoor unit of the air conditioner, in a simple and popular way, connects the outdoor unit of the air conditioner with a sprinkler and uses water flow to cool down, which can save electricity by 15% and reduce the temperature by 4-10 degrees.
Although the installation of pure water manufacturing device and sprinkler system makes users have to spend a sum of money, the amount of electricity saved is very large. After accounting, it is found that the investment can be recovered in about 2 years, and the benefits can be sustained forever.
Theoretically, the outdoor air conditioner spray energy-saving system is suitable for all air conditioners, but in fact, it is mainly used in large-scale air-conditioning equipment in enterprises and institutions, because the comparison between energy-saving effect and benefit is obvious, and both suppliers and users are active.
In recent years, the outdoor temperature in summer is getting higher and higher than in previous years.
The poor heat dissipation conditions make the heat dissipation capacity of large and medium-sized air-cooled condensing units more and more unable to meet the ex-factory design requirements of air-conditioning equipment (the design temperature outside the air conditioner is generally 35 ℃ in summer. Nowadays, the global climate can reach 50 ℃ in the hottest summer-the dry bulb temperature is above, and the heat dissipation area and ventilation capacity of the air conditioning outdoor condenser are obviously on the small side).
Taking the installation platform of the special air-conditioning outdoor unit (belonging to air-cooled condenser) in the communication room of Beijing Jingmen Building as an example, because the special air-conditioning outdoor unit in the computer room has no ideal location, we can only use all available space to install special air-conditioning outdoor units around the building.
At present, the area with the worst operating environment is the five-story outdoor platform on the north side of the building, where more than 50 air-cooled condensing units with special air conditioners (60,000 / 70,000 calories) are installed in a narrow and long passageway of 100 meters long and four meters wide. there are very high walls or noise barriers on the two long sides of the passage to block the horizontal flow of air, and the ventilation effect is very poor.
In summer, when the external temperature reaches 30 ℃, the air temperature in the five-story outdoor platform will reach more than 50 ℃ (measured 1.5 meters from the platform ground)!
Once the air temperature rises to 35 ℃, the special air conditioner in the computer room generally goes down due to high pressure alarm, which seriously affects the stability of the temperature in the computer room, and the spray cooling system outside the air conditioner can effectively play the cooling effect and make the air conditioner work normally.
