Introduction Evaporative cooling is a process that cools air through the simple evaporation of water. 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. In order to give the maximum heat transfer and minimize scaling, the coil must be drenched with water at all times. 13(a) that the total energy consumption of the composite air conditioning system after using the water-cooled condenser are reduced by 9.33%, 9.20%, 8.98%, 8.83% and 8.26%, respectively. Fresh air flows into the condenser from the bottom, and the cooling tube ring goes down to the supercooled state. While you may be motivated to run the small spray pump first to save money, this isn’t a simple equation. the evaporative condensers with galvanized coating become more and more obsolete due to the environmental emissions and the use of aggressive chemicals either at the galvanization process or at water treatment systems. 0000510398 00000 n 0000003831 00000 n condensers, beginning with single condensers and exploring multiple condenser installations as well as thermosiphon and sub-cooling piping systems. However, the specific materials of construction will determine the water chemistry confines within each respective system. This excess heat is eliminated by evaporating the water. As a result an evaporative- cooled condenser can be 20% to 40% more efficient than a … An evaporative condenser is used to remove excess heat from a cooling system when the heat cannot be utilised for other purposes. The concentration of total dissolved solids (TDS) will increase in the closed-loop system as the water evaporates. 0000012500 00000 n Cooling towers and evaporative condensers help to remove excess heat from sites like power stations or chemical plants. Disadvantages of Evaporative Condenser: (1) The water may freeze at low operating temperatures. ) The low- er condensing temperature means that the evaporative-cooled condenser can reject more heat than an air-cooled condenser, while requiring less compressor work and consuming less energy.

Evaporative condenser is used in those cases in which the heat of the refrigerant, coming from a refrigeration system, can not be used. Basin water temperature is typically not permitted to get below 40ºF to prevent freezing. This cooling system is based on the same physical principle as the cooling towers. Therefore, the theory of evaporative condensers The water consumption is only 1% of the water-cooled condenser. EVAPCO, Inc. is an industry leading manufacturing company with global resources and solutions for worldwide heat transfer applications. 0000007090 00000 n 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. Water Distribution System zPlastic spray header and branches zLarge orifice, non-clog nozzles zGrommetted for easy maintenance 3. The total annual cost of water at the facility is $52,706 based on 95 cents per kilolitre. VXC - E 7 Evaporative Condensers... because temperature matters 1. Coil zCoil according to European Pressure Equipment Directive 97/23/EC zContinuous serpentine, steel tubing 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. 0000011888 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. Many factors are involved. Evaporative Condensers offer energy savings by providing lower system condensing temperatures than conventional air-cooled or water-cooled condensing systems. The excess heat is removed by evaporating water. 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. 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. Evaporative condensers have a high daily water consumption rate but in return they offer reduced electrical running costs vs most other forms of condenser. SPX Cooling Technologies, Inc. is a leading global manufacturer of cooling towers, evaporative fluid coolers, evaporative condensers and air cooled heat exchangers. 0000008886 00000 n Keywords: condenser evaporative precooling; rooftop air conditioners; building energy modelling; control strategy 1.

When used within an evaporative application specific consideration needs to be given to the water chemistry within the system. Water, as an important resource, can be rare and precious, especially in hot and dry areas where an evaporative condenser is highly applicable. They use evaporative cooling to remove heat from the refrigerant vapour. The excess heat is removed by evaporating water. 0000506380 00000 n 0000407867 00000 n Background Evaporative condensers came into common use for nearly all refrigeration systems because of their operating advantages over the combination of cooling towers and condensers. For industrial companies using a cooling tower for its facility, some type of cooling tower water treatment system is usually necessary to ensure an … Although a common feature in large commercial air-conditioning systems, the evaporative condenser is seeing an increase in use in smaller domestic air conditioners. This is normally accomplished with the use of optional basin heaters. energy and water use, effective water treatment also helps reduce the negative environmental impact and carbon dioxide emissions associated with a facility. Impurities in the vapours(2 (3 may cause corrosion.) 0000002094 00000 n This complete process of cooling tower,pumping and condensation can be integrated to evaporative condenser, The evaporative condenser is essentially a combination of a water-cooled condenser and an air-cooled condenser, utilizing the principle of heat rejection by the evaporation of water into an air stream traveling across the condensing coil. evaporative condensers. Evaporative coolers and condensers The evaporative condenser has a cabinet with a water-sprayed condenser, and it usually has one or more fans. 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 … An evaporative condenser is used to remove excess heat from a cooling system when the heat cannot be utilized for other purposes. using high efficiency fans guarantees a lower power consumption in motors. 0000407904 00000 n 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.
