Environmental protection air conditioner (wet curtain air cooler) is a new type of energy saving and cooling equipment developed by national colleges and universities.

Its output is large, the price is low, the electricity consumption is saved, the air is fresh, the installation is convenient, and the operation is reliable. The utility model can be widely used in the following places:
1, socks, clothing, textile, rubber, plastic spraying, screen printing, toys, electronics, electrical appliances, footwear, food, printing, dyeing, processing, laundry and other workshops with high temperature sm_2all.
2 large and medium-sized shopping malls, farms, waiting rooms and large indoor entertainment.
3 a place where there is a strong smell of toxic gas or dust.
4 has been installed in the traditional air conditioning, but fresh air (or oxygen) insufficient places.
Use and maintenance of environmental protection air conditioner (wet curtain cooling fan):
1, the machine is suitable for 70-100 square meters room cooling.
2, air cooling machine before use, please check the wet curtain and pools without paper scraps and dust and other debris, the annual should use the cleaning 1-2 times, join in the pool water should be clean tap water or other water, to keep the pipeline unimpeded into the wet curtain with high efficiency.
3, the fan is the whole heart, if the fault should be immediately cut off the power supply, timely electrician repair. The installation should pay attention to connect the ground, to ensure personal safety, be careful disassembly of the impeller, so as to avoid the deformation and the blades together. After the installation of cold air, the box cover should be locked, so as not to blow the lid off.
4, floating ball valve in the pool water level can automatically recharge when the upper limit of water level, if the failure of the control, found in the pool of water or overflow, should be adjusted or replaced.
5, such as the discovery of the wet curtain water supply shortage or uneven check pool is lack of water, if the water pump operation, water supply pipe and a water inlet pipeline of the water above the keyhole is clogged, and check the water height should be greater than 80MM.
6, because the fan is low pressure (static pressure, dynamic pressure are small), it can not be used in the outlet of the cold air outlet pipe to the long-distance wind.
7, the fan and pump circuit should be centralized control, control switch should be installed indoors.
8, after the installation of cold air blower, the box cover should be column, so as not to blow the lid off.
9, when the winter cold air machine is not used, the pool water to be released, and the use of plastic sheeting or cotton cloth box, so as not to wind into the room.
Structure and working principle of environmental protection air conditioner (wet curtain cooling fan):
Wet curtain cooling fan (environmental protection air conditioning) is by the surface area of great special paper honeycomb corrugated wet curtain, high efficiency and energy saving blower, the water circulating system, float valve installed, replenishment cold set cabinet and the electric appliance components, five kinds of new air conditioning technology you don't know, the cooling principle is: when the fan operation when entering the cavity negative pressure, wet curtain surface makes the external air flow through the porous wet curtain to force the air dry bulb temperature to the wet bulb temperature close to the air outside the 9_2wfqy, namely the outlet of fan dry bulb temperature than the outdoor dry bulb temperature (5-12 DEG C lower dry heat area up to 15 DEG C), the air is dry, the temperature difference is bigger, the cooling effect is better. Because the air is always introduced from outside, so can keep the indoor air fresh; at the same time as a result of this machine use evaporative cooling principle, it has double functions of cooling and humidification (relative temperature up to about 75%), used in the textile and knitting workshop, not only can improve the cooling and warming conditions, but also purify the air in the process of knitting needle, reduce fracture rate, improve the quality of textile products.

Specification for installation of environmental protection air conditioner wet curtain air cooler:
The cold air blower is installed outside the window and the wall, and is connected with the window or the wall or the wall hole by a pipe joint. Cold air outlet should be higher, not direct blow the human body. Before installation, the angle bracket is welded with angle steel, and the parameter size is determined by the installation site. Taking into account the safety of the people into the machine, the 40-50 angle. The distance from the wall should be greater than 30CM, so as not to enter the side of the wet curtain airflow blocked.
The fan ventilation generally has two vertical and horizontal airflow, transverse ventilation over-current fault area, the wind speed is small, easy to cause a large area of dead, while the longitudinal ventilation fault area is small, the wind speed is high, the dead area is very small. In the case of the use of conditions permit, should be as far as possible the use of advanced longitudinal ventilation.
