Evaporative condenser is the main heat exchange equipment in refrigeration system, its principle is: refrigeration system in the compressor exhaust superheated high-pressure refrigerant gas through the evaporation condenser of the condensate tube, so that high-temperature gaseous refrigerant and pipe outside the spray water and air heat exchange. That is, the gaseous refrigerant is gradually condensed into a liquid refrigerant from the top to the bottom. The strong wind force of the supporting fan makes the spraying water completely evenly cover the surface of the coil, and the water by the wind, greatly improves the heat transfer effect. The rising temperature of the spray water from the part into a gaseous, using the latent heat of water from the wind to take away a lot of heat, the water droplets in the hot air are stopped by the high-efficiency dehydrating device, and the rest absorbs the heat, scatters into the heat exchange layer of the PVC drench, and is cooled, the temperature drops, enters the water tank, then circulates the water pump to continue to circulate. The water that evaporates into the air is automatically replenished by the water level regulator.
HEAT exchanger tubes are used in many forms, commonly used in carbon steel hot dip galvanized pipe (also divided into round pipe and oval tube), aluminum alloy tube, stainless steel pipe (also divided into 314/316 round pipe, wave take over); carbon steel hot-dip zinc evaporative condenser for the earliest start of the use of products and occupy most of the domestic users are mainly used in high-pressure gas condensation, cooling, The applicable pressure range is 0-30mpa; aluminum alloy Evaporative condenser is a new generation of energy-saving products suitable for ice machine refrigerant condensation, applicable pressure range in 0-5mpa; the stainless steel tube evaporative condenser is mainly used in the corrosive gas cooling and condensation process of some chemical plants.
Refrigeration evaporative condenser shell generally with galvanized plate spray plastic, after the corrosion resistance, gradually used aluminum galvanized plate spray, the latest use of the market is aluminized magnesium zinc plate, this plate has stainless steel features, not rusty, good-looking, easy to process.
