The air-cooled condensation unit of wet curtain evaporative cooling that provides for achieving the above object is a kind of by direct evaporation cooling technique (is promptly utilized cooling air spray humidification is reduced air themperature, utilize the tiny globule that carries in the humid air technology then in the double evaporation-cooling heat absorption of condenser copper tube surface) be applied to the device of optimizing structure in the conventional air-cooled condensation unit, it comprises that the air inlet place is provided with the shell of filter and is located at the interior condenser of shell, condenser fan, compressor, evaporimeter and heating power expansion valve etc., the gas outlet of compressor is connected with the air inlet of evaporimeter behind condenser copper tube and heating power expansion valve, the gas outlet tieback of evaporimeter is to the air inlet of compressor, between the air intake grid face of filter and condenser, hang a cooling cascade is housed, below the cooling cascade, be provided with the drip tray of connecting with the running water inlet pipe, drip tray is built-in with water circulating pump and is provided with the level controling floating ball valve, and the water-supply-pipe spray head of water circulating pump is positioned at the top of cooling cascade.In the practical application, this condensation unit utilizes evaporimeter that the cooling air that enters condenser is carried out the humidification preliminary treatment, and the contained globule of cooling air carries out evaporative condenser in condenser, thereby can reach effect energy-conservation and that improve the COP of system effectively.

Operational mode of the present utility model is as described below:

1. Wet-curtain temperature reducing---cooling water is stored in the drip tray of bottom half, keep certain water level with ball-cock assembly, cooling water in the drip tray is delivered to the water-supply-pipe spray head with water circulating pump, on the nozzle spray is being lowered the temperature wet curtain, in cascade, form moisture film, be evaporated to steam after the part water heat absorption in the moisture film and taken away by air, humid air is taken away a part of tiny globule simultaneously, and all the other water still drip in the water returning disk;

2. evaporative condenser---the cooling humid air that carries a large amount of tiny globules behind the curtain moistening and lowering temperature that wets through lowering the temperature passes to condenser from the air intake grid, cold-producing medium with HTHP behind the globule chance condenser high temperature copper pipe carries out heat exchange, humid air cools off cold-producing medium, the contained globule of humid air carries out the double evaporation-cooling heat absorption simultaneously, strengthen the heat exchange effect, cold-producing medium is cooled to liquid gradually, and the hot humid air after the heat absorption is discharged in the ambient atmosphere by condensation fan;

3. evaporation---by the refrigerant liquid of temperature in the high pressure after the condenser condenses, through the refrigerant liquid after the heating power expansion valve throttling, evaporator evaporation in the inlet chamber is returned compressor compresses then.

Compared with prior art, the advantage that has of the air-cooled condensation unit of wet curtain evaporative cooling described in the utility model comprises:

1. energy savings---the special design of the utility model can make the air themperature that enters condenser reduce by 2~4 degree than general air-cooled unit EAT, add the globule evaporative condenser effect that humid air is contained, the condensation temperature of unit reduces, consumption of compressor reduces, therefore its Energy Efficiency Ratio is higher than the conventional air-cooled unit under the identical operating mode, energy savings greatly;

2. reducing cost---after condensation temperature reduced, condensation effect improved, and therefore, can reduce the condenser area, reduced system cost;

3. increasing the service life---after condensation temperature reduced, condensing pressure decreased, and can prolong the service life of compressor like this, reduced maintenance cost.
