Product Description ZNX series evaporation condenser is designed according to JB/T7658.5-2006 "evaporation condenser for ammonia refrigerating device" standard.Basis on many years of design production experiences , integrated the advantages of similar products at home and abroad.The product have novel structure, unique, advanced and reasonable, safe and reliable, high efficiency;it can adapt to all kinds of different temperature requirements, which are widely used in refrigeration, cold storage, ice storage, hotels, shopping malls and large factories and other places.Structural FeaturesThe condenser and cooling tower organically integrated, energy saving.Air and water flow same, affect the heat transfer coefficient.Heat exchange pipe tilt design, it is good for refrigerant flow, reduce the flow resistance.Evaporation condenser side have maintance door, easy for maintenance.Axial flow fan blades is die casting aluminum, light weight, low noise,high efficiency and motor is waterproof.Heat exchange coil and internal black metal artifacts have been hot-dip zinc process, good anti-corrosion performance, long life time ;Heat exchange coil with special structural design, make the coil arrangement more compact, increased in the same plane coil area, improving the heat transfer efficiency.Using anti-blocking type spray system, large coverage area .Use high-efficiency dehydrator, dehydration with high efficiency, water loss is small.Heat exchange coil with heat transfer layer below the secondary water distribution, increase the contact area, reduce the water temperature, spray water cooling effect is good, so as to ensure the evaporation condenser effect.Specification Working PrincipleThe vapor evaporate and take away the heat of the refrigerant. During operation, the cooling water is pumped up to the nozzle on the top of condenser and evenly spraying to the outside surface of condensing tubes and forming a water layer. The high temperature refrigerant gas come into the condensing coils from top and condenses by cooling water into liquid and flow out from bottom. Some water absorb the heat and become steam, the rest water drop to the water tank for re-circulation, meanwhile, the fans on the top make wind with speed of 3~ 5 m/s to speed up the evaporation of the water layer outside the surface of condensing tubes and also cool the dropping water which will get back to spay onto the heat-exchange tubes. The steam is blown out by the blower and the blobs mixed to the steam remain on the dehydrator. The floating valve in the tank control water supplement into the tank automatically. Advantages of evaporation condenser Power-saving: The condensing temperature of evaporation condenser is decided by wet ball temperature. Normally, the wet ball temperature is 6 ~ 8C lower than ambient temperature. So we designed the structure of the evaporation condenser according to this to lower the condensing temperature and system pressure; so that to increase the refrigerating capacity of the compressor and reduce the power consumption. The power of water pump is only 1/3 ~ 1/4 compared with other water-cooled condenser. According to the calculation and operation, the power consumption of evaporation condenser is 15% lower than water-cooled condenser.Water-saving: the evaporation condenser use water evaporation to take away the heat -1 liter of water evaporated will take away 670W of heat. But water-cooled system use water heating-up to take away the heat -1 liter of water only can take away 4 ~ 5W of heat. Therefore, to remove same volume of heat the water-cooled condenser needs more water (we need to prepare large water tank, cooling tower and cooling tubes which will bring more chance for water losing). Contrarily the evaporation condenser needs less water and meanwhile the dehydrator of the machine has higher efficiency of water reclaim. The water loss of evaporation condenser is only 10% of water-cooled condenser.Space-saving, easy to install and short duration.The evaporation condenser is an integrated machine include condensing coil, cooling tower,water pond and water pump, which can be put on the top of the roof. The piping system is simple and there is no other accessory of water system.It will reduce the installation material, construction period and installation cost.Low maintenance cost. If we use evaporation condenser, the condensing temperature will be low, what's more, the exhaust pressure, exhaust temperature and the temperature of lubrication oil are also low. So the machine is working under a perfect condition, and the lifetime of the machine will be longer and the running of the machine is more smoothly so that to reduce the maintenance cost.Detailed PhotosApplication1) The evaporative condenser is one of the most important parts of the whole, refrigeration system .2) The condenser condenses the refrigerant gas inside the coil and complete a heat exchange circle .3) The evaporative condenser is widely ,applied to cold storage ,ice-store , chemical industry ,supermarket and etc.Our FactoryCompany Profile
