Introduction to indirect evaporative chiller - this equipment is based on one or more national invention patent technologies

Evaporative cooling technology uses unsaturated air to directly contact with water, and water evaporates and absorbs heat, resulting in the reduction of the temperature of air or water.

Evaporative cooling equipment uses this principle to produce cold water or cold air.

Compared with conventional evaporative cooling technology, indirect evaporative cooling technology can prepare cold water and cold air with lower temperature.

The indirect evaporative chiller is composed of fan and heat exchanger + air cooler + water spray device, etc. the water flows vertically in the tower, and the air flow direction is opposite to the water flow direction. In summer, the inlet air is entering the air_ Before the water directly contacts the packed tower, it is precooled by the air cooler. The water of the precooled air is the water supply or return water of the cooling tower. In the tower, the spray water contacts the pretreated air for evaporative cooling to prepare the cooling tower water supply.

 

Four features:

◆ replace the compressor

Indirect evaporative chiller is used for heat removal in tire production. The required cooling capacity is 4000kW. The original traditional cooling is used, and the machine power reaches 800KW / h;

The indirect evaporative water chiller is currently used, and the machine power is as low as 150kw/h, and 16_ 22 ℃ cold water, realizing reliable and stable operation throughout the year.

◆ extend free energy utilization time

The traditional cooling mode can use free natural energy for about 2 months every year; Indirect evaporative cooling technology can extend the time of free energy for about 4 months.

For example, in Gansu, Xinjiang and other places, free energy can be used for up to 6 hours a year_ 12 months.

◆ high efficiency and energy saving

The condensing condition at 28 ℃ is equivalent to the condensing condition at 32 ℃. The efficiency of the refrigeration unit is improved:

1. The efficiency of refrigerator with full liquid evaporator is increased by more than 80%

2. The efficiency of refrigerator with dry evaporator is increased by more than 50%

3. Increase the efficiency of lithium bromide refrigerator by > 40%

◆ antifreeze in winter

Indirect evaporative cooling can circulate hot water all year round at the air inlet to ensure that the temperature at the air inlet is higher than 0 ℃ all year round, which can better play the role of antifreeze.
