1 Work Principle of evaporative condensers

2.1.1 Wind Cooling:

YZTL series evaporative condenser uses water and air as

Cooling agent.The cooling agent exchanges the heat with

High temperature gaseous refrigerant agent and hence the

refrigerant agent becomes liquid.inside it has a water

distribution system, condensing coils,wet deck ,dehydrator and

so on. Outside it has a water circulating pump , a propeller fan

on the top of condensing coil. The propeller fan strengthens

the flow of the air and causes negative pressure inside.

when the condenser runs,the cooling water is pumped and

then sprayed by water distribution system On the surface of

condensing coil equably to form a thin layer of water film.

2.1.2 Water Cooling:

The high –temperature steam of refrigerant agent enters from the top of condensing coil and then the cooled liquid refrigerant agent is discharged from the bottom of the condenseing coil .during this process,high temperature refrigerant agent exchanges the heat with the water and air outside the coil and increases the the effect of heat exchange with the help of wind .after aborbing the heat of refrigerant agent .some water turns into steam and is discharged by fan .meanwhile,the moisture in the

Air is collected by dehydrator to basin.and the ungasified cooling water flows into wet deck and its heat is taken away by the airflow .the cooled water converges in the basin to be used circularly by the pump.

In addition,there is a ball cock in the basin .when the water is consumed to a certain point the ball cock

Will automatically open to replenish the cooling water.

2.2 Evaporative Condensers Configuration and Technical Performance

The evaporative condensers main machine consists of shell, cooling coils, air discharge system, spray system, drift Eliminator and water basin etc.

• Shell:The evaporative condensers shell is made of alum-zink galvanized plate. The machining by digitally controlled equipments requires no welding and makes outside appearance smooth and aesthetic looking.

• Cooling coil: The cooling coil, as core part of the evaporative condenser, realizes heat rejection via wind and water cooling effect; KEJU cooling coil adopts high-quality seamless steel coils with thickness of∮=25mm. the design pressure is 1.97Mpa.all the coils have been pneumatically tested 3 times at 2.5Mpa to avoid being rotten. It requires no fins and guarantees perfect cooling effect. 3 times leak tests in 10 bars are carried out for guarantee of air-tightness.

• Wind System: Main function of this is to discharge the saturated hot air inside the cooling tower. It’s made of air inlet louvers, fan, fan cylinder and protection grid etc.
