Evaporative coolers, often called "swamp coolers", are cooling systems that use only water and a blower to circulate air. When warm, dry (unsaturated) air is pulled through a water-soaked pad, water is evaporated and is absorbed as water vapor into the air. The air is cooled in the process and the humidity is increased. Indirect-contact (closed-circuit) cooling towers contain two separate fluid circuits: (1) an external circuit, in which water is exposed to the atmosphere as it cascades over the tubes of a coil bundle, and (2) an internal circuit, in which the fluid to be cooled circulates inside the tubes of the coil bundle. refrigerant and water, and to improve the chiller efficiency. - the exceptional COP and IPLV values exceed the national and international energy norms like ECBC and ASHRAE 90.1.

One transfers the heat from warmer water to cooler air mainly by an evaporation heat-transfer process and is known as the evaporative or wet cooling. These are also termed as open systems. The other transfers the heat from warmer water to cooler air by a sensible Russell Sigler Inc. | HVAC Distributor a convective, a direct quench cooler or any combination of these coolers. The selection and actual design of a syngas cooling system are influenced by factors such as the type of gasifier used, the characteristics of the coal feed, the overall gasification process application and costs. Various high temperature syngas The Version 2.0 ENERGY STAR specification for Water Coolers has been finalized and will take effect on February 1, 2014. Materials related to this revision process are provided below. Partners and other interested parties with questions or concerns regarding these materials or the revision process can contact Tanja Crk, EPA, at Crk.Tanja@epa VARIOUS PARTS • 1. Fan & Vents- A fan is needed to direct the cool air towards the room.These fans continuously flow cool air in the room. • 2.Water source- Evaporative cooler used water so it is necessary to fill the cooler with water so that the cooling can take place. 6. The main parts in the water-cooling system are: (i) water pump, (ii) fan, (iii) radiator and pressure cap, (iv) fan belt (v) water jacket, (vi) thermostat valve, (vii) temperature gauge and (viii) hose pipes. Water Pump This is a centrifugal type pump. It is centrally mounted at the front of the cylinder block and is usually In the winter, a water-to-air heat exchanger extending from the water heater supplies warm air to the system. Contact: Davis Energy Group. Also appropriate for dry climates, the Coolerado Cooler is an evaporative cooling technology that is 100% indirect. It can offer four to six tons of cooling with an energy consumption of 1,200 watts. Different Types of Evaporative Coolers 1. Direct Evaporative Air Cooler With direct evaporative cooling process, a blower forces air through a permeable and water soaked pad, wherein the air is filtered and cooled, as well as humidified. This type of swamp cooler is very effective in managing temperature. Different Types of Evaporative Coolers 1.
