Working principle of water-cooled air conditioner
The refrigeration principle of water-cooled air conditioner (evaporative air conditioner) is: when the fan is running, it enters the cavity to produce negative pressure, which makes the air flow outside the machine too much? The wet curtain surface of the water-cooled air conditioning hole forces the dry-bulb temperature of the air passing through the curtain to approach the wet-bulb temperature of the air outside the machine, that is, the dry-bulb temperature at the outlet of the air cooler is 5- 12℃ lower than the outdoor dry-bulb temperature (up to 15℃ in dry-hot areas), and the hotter the air is, the greater the temperature difference is, and the better the cooling effect is. Because air is always introduced into the room from the outside (called positive pressure system at this time), it can keep the indoor air fresh; At the same time, due to the evaporative cooling principle, the machine has dual functions of cooling and humidification (the relative temperature can reach about 75%). When used in textile and knitting workshops, it can not only improve the cooling and humidification conditions, but also purify the air, reduce the needle breakage rate in the process of needle spinning and improve the quality of needle spinning products. ? The air cooler (evaporative air cooler) is equipped with a honeycomb wet curtain made of special materials, which has a large surface area and is constantly humidified by the water circulation system; A high-efficiency low-noise energy-saving fan is installed in the wet curtain cooling fan. When the fan is running, the wet curtain cooling fan generates negative pressure, so that the air outside the machine flows through the porous wet curtain and enters the machine. As the moisture on the wet curtain evaporates, the air passing through the wet curtain is forced to cool down. At the same time, because the water on the wet curtain evaporates into the air flowing through the wet curtain, the humidity of the air is increased, so the wet curtain cooling fan has dual functions of cooling and humidifying.
Principle of industrial water-cooled air conditioning
Dry air coolers are usually used in industry. It relies on forced air flow outside the cooling pipe generated by evaporation in the air cooler. Installed on the floor in the cold storage, it is called floor air cooler; Installed at the top of the warehouse, it is called ceiling air cooler.

Characteristics of evaporative water-cooled air conditioner;
1, the cooling effect is obvious: in humid areas (such as southern areas), it can generally achieve obvious cooling effect, about 5-9℃;
2, ventilation, air exchange, dust prevention, deodorization, cooling in one, increase air nutrients, improve work efficiency.
3. It is equipped with the functions of automatic water supply, automatic aeration, automatic cleaning and air supply, which can realize automatic protection of water shortage and phase shortage.
Cooling coils, the key component of high-efficiency air cooler, is composed of advanced fins and heat exchange tubes. It adopts new tube expanding technology, advanced design structure with variable blade spacing at the outlet side, and staggered heat exchange tubes to ensure perfect airflow organization, uniform and reasonable airflow distribution and realize high-efficiency heat exchange. Not easy to frost, defrosting is efficient and simple.
High-efficiency air cooler with patented QDZ (or FDZ) series axial fan, high efficiency, energy saving and low noise. Axial flow fan has wide effective area and large air volume, can adapt to multi-working conditions and run efficiently, saves a lot of energy consumption, runs smoothly and has long service life.
The shell of high-efficiency air cooler is made of advanced high-precision special numerical control equipment, which ensures the long-term stability and consistency of product quality of air cooler. The material of the shell plate is divided into: galvanized sheet, galvanized sheet spray, galvanized sheet, stainless steel sheet, hot-dip galvanized steel sheet, aluminum sheet, etc. The use of shell plate is selected by users according to their needs.
High-efficiency air cooler heat exchange tubes include high-quality seamless steel tubes, high-quality stainless steel seamless steel tubes, high-quality seamless aluminum tubes and copper tubes. The heat sink is made of steel, aluminum and stainless steel. The types of finned tube groups are steel tube, aluminum tube, aluminum tube, stainless steel tube, stainless steel tube and copper tube.
The structural types of high-efficiency air coolers are floor-mounted (L), floor-mounted upward blowing (LS), floor-mounted downward blowing (LX), floor-mounted flat blowing (LP), ceiling-mounted (D) and assembled (PP, PD).
High-efficiency air cooler is the equipment that outputs cooling capacity in refrigeration system, which is mainly composed of cooling coils and axial fan. Under the forced action of the axial fan, the air in the cooled room is forced to carry out convective heat exchange through the cooling exhaust pipe group of the air cooler, so as to cool the air, thus achieving the purpose of reducing the temperature of the room (or warehouse).

Location selection
The geographical location of water-cooled air conditioning installation can be related to the air supply volume and air freshness of the air cooler. How should we choose the installation position of air cooler? I don't know if you realize it. If you don't have any friends, come and have a look with the author! Only by clearly understanding the air cooler can we use it better.
For the installation of air cooler, we should install it outdoors to ensure that fresh air comes back to run. If conditions permit, we can try to install the main engine in a place with good ambient air quality. Do not install it in the exhaust port with smelly or peculiar smell gas, such as polishing, toilet, kitchen, etc.
The water-cooled air conditioner can be installed on the wall, roof or outdoor floor, and the air duct should be avoided from being too long. Generally, the length of 15-20m is the best, and the elbow of air duct is minimized or not used.
When the main engine of water-cooled air conditioner is running, a certain area of doors or windows should be opened for ventilation. If there are not enough doors and windows, an exhaust fan should be installed, and the exhaust air volume should be 80% of the total air supply volume of the air cooler.
The main frame of air cooler needs to be welded with steel structure, and its structure is required to support twice the weight of the whole machine body and maintenance personnel.
How about domestic water-cooled air conditioner?
1, which dissipates heat by evaporation of water. Water is a pollution-free renewable resource, unlike traditional air conditioners, which need snow seeds to help dissipate heat, reduce freon emissions and protect the ozone layer. Therefore, water-cooled air coolers are also called environmental protection air conditioners and green air conditioners.
2, no compressor, no cold coal, only rely on the rotation of the fan motor to generate cold air, saving electricity and worry, green and practical.
3. Low operating cost. Compared with the traditional compressor air conditioning series, the power consumption is only1/8-110.
