As a result an evaporative- cooled condenser can be 20% to 40% more efficient than a … Principle Operation Evaporative condensers provide heat rejection for many types of systems, and the specific application will largely determine which BAC Evaporative Condenser is best suited for a project. Many factors are involved. It is essentially a hybrid between an air-cooled condenser and a water-cooled condenser which uses the principles of heat rejection to follow an evaporative process. The excess heat is removed by evaporating water. The excess heat is removed by evaporating water.

Therefore, the theory of evaporative condensers The water consumption is only 1% of the water-cooled condenser. When used within an evaporative application specific consideration needs to be given to the water chemistry within the system. The water cooled system through highly efficient MITA Group evaporative condensers work adiabatically. For the evaporative cooling vapor compression mode, adding a water-cooled condenser can effectively reduce the overall energy consumption of the system., it can be seen from Fig. Fresh air flows into the condenser from the bottom, and the cooling tube ring goes down to the supercooled state. Users can reduce peak energy use by 44% vs. traditional air-cooled products or reduce water use by 90% vs. traditional evaporative products. There is pressure to reduce this water consumption. Taking into account factors such as splash loss, sewage and water exchange, the actual water consumption is about 5% to 10% of the water-cooled condenser. An evaporative condenser is designed to condense a refrigerant gas and a fluid cooler cools process water contained on the inside of the units tubes. Heavy Duty Construction zZ600 hot-dip galvanized steel panels 2. Precautionary measures . These systems use approximately 5-8 gallons (19-30 liters) of water which is circulated over the condenser for eight hours before being purged from the system completely and replaced with fresh water. Cooling towers and evaporative condensers help to remove excess heat from sites like power stations or chemical plants. 3.The structure is compact. Coil zCoil according to European Pressure Equipment Directive 97/23/EC zContinuous serpentine, steel tubing 0000016228 00000 n SLC Low Water Consumption Evaporative Condenser Production introduction Water Cooled Industrial Evaporative Condenser for Cold Room mainly flows through the reverse flow of air and water. TrilliumSeries™ Adiabatic Products combine the best of evaporative and dry cooling to optimize energy and water savings. The water consumption found under Air-Conditioning, Heating and Refrigeration Institute-Test A and conditions of 95°F DB and 75°F WB were purged 0.59 gal/hr/ton of water each hour and evaporated 1.86 gal/hr/ton for a total water consumption of 2.45 gal/hr/ton. Thus it is urgent to optimize the spray pattern and take into account nozzle shape, water spray rate, spray orientation, and spray pattern to minimize water consumption. Introduction Evaporative cooling is a process that cools air through the simple evaporation of water. 0000013351 00000 n Water Distribution System zPlastic spray header and branches zLarge orifice, non-clog nozzles zGrommetted for easy maintenance 3. They are compact, quiet, consume little energy and save more than 95% of the water … 0000510398 00000 n Evaporative condenser.

Disadvantages of Evaporative Condenser: (1) The water may freeze at low operating temperatures. ) EVAPCO, Inc. is an industry leading manufacturing company with global resources and solutions for worldwide heat transfer applications. Impurities in the vapours(2 (3 may cause corrosion.) Traditional approach is the use of water treatment chemicals to control scale, corrosion, fouling and microbiological proliferation ie legionella Industry standard is to subcontract the ownership of the water treatment to an external specialist contractor to … 4 Reducing water use in cooling towers and evaporative condensers optimising blowdown is often the greatest opportunity to reduce water consumption in cooling towers and evaporative condenser installations. 0000002094 00000 n Evaporative condenser by BAC. Conditions. needed. The total annual cost of water at the facility is $52,706 based on 95 cents per kilolitre. An additional cost of $40,000 per year is 0000010330 00000 n Cooling towers and evaporative condensers are efficient and cost effective means of removing heat from air conditioning, refrigeration and industrial process cooling systems. 0000006907 00000 n This is because the … 109 0 obj <> endobj xref 109 31 0000000016 00000 n * Please note that any pop up blockers your browser may employ will interfere with the ability to “Generate Curves”. Water, as an important resource, can be rare and precious, especially in hot and dry areas where an evaporative condenser is highly applicable. This cooling system is based on the same physical principle as the cooling towers. This is normally accomplished with the use of optional basin heaters. 0000014806 00000 n 0000012500 00000 n Then. Use BMS to Guide Evaporative Condenser Operations. This excess heat is eliminated by evaporating the water. 0000008886 00000 n As an example a typical ammonia plant for a 1000 Pallet freezer store will consume an estimated 10 000 to 12 000 litres of water daily in summer. They have been in use for more than half a century. 0000000916 00000 n For industrial companies using a cooling tower for its facility, some type of cooling tower water treatment system is usually necessary to ensure an … An evaporative condenser is used to remove excess heat from a cooling system when the heat cannot be utilised for other purposes. The water is circulated from the basin located at the bottom of the unit up to the top and distributed by spray nozzles to optimize tube cooling coverage. %PDF-1.4 %���� 0000014918 00000 n The spray nozzles will distribute the 0000418618 00000 n Another important part of an evaporative condenser is the water distribution system. The evaporative condenser has a cabinet with a water-sprayed condenser, and it usually has one or more fans. They use evaporative cooling to remove heat from the refrigerant vapour. he saving on total cost (4 may not be significant.) However, the specific materials of construction will determine the water chemistry confines within each respective system. The EVAPCO system does this by circulat-ing approximately 4 l/s over every square meter of coil sur- SPX Cooling Technologies, Inc. is a leading global manufacturer of cooling towers, evaporative fluid coolers, evaporative condensers and air cooled heat exchangers.
