Units. evaporative condensers. A condenser coil is one of many types of heat exchangers. The primary purpose of a heat exchanger is to efficiently transfer heat between two mediums. Condenser coils are found in space heaters, air conditioners, and car radiators. Although there are slight differences in the function of these devices, the primary purpose is the same. In so doing, the latent heat is given up by the substance and transferred to the surrounding environment. The major types of condensers used are (1) water-cooled, (2) air-cooled, and (3) evaporative. Evaporative condenser is used in those cases in which the heat of the refrigerant, coming from a refrigeration system, can not be used. An evaporative condenser is a device which facilitates the condensation, or return to a liquid state, of a hot gas or vapor in a tube system using the evaporation of water flowing over the tubes. When the air and water come together, a small volume of water evaporates, creating an action of cooling. This excess heat is eliminated by evaporating the water. Water is pumped from the sump of the evaporative condenser to a spray header and sprayed over the condenser coil. Input Restrictions. Evaporative Condensers : In systems involving heat transfer, evaporative condenser is a device or unit used to condense a substance from its gaseous to its liquid state, by cooling it. Heat transfer in evaporative condensers is similar to that of air-cooled condensers, except for the complexity of mass transfer due to evaporation on the exterior surface of the tube. Input … The principle underlying evaporative cooling is the fact that water must have heat applied to it to change from a liquid to a vapor. Commonly, the cooling waterflows through the tube side and the steam enters the shell side where the condensation occurs on the outside of the heat transfer tubes. There is a thin water film aroundcondenser tubes from which cooling takes place. A high relative humidity will: a. increase evaporative condenser capacity because there is more moisture in the air b. increase the infiltration load on a refrigeration system The water is exposed to air as it flows throughout the cooling tower. In simple terms, an evaporative condenser uses a system of tubes exposed to a constant flow of water to cool and condense a hot gas. The function of the condenser in a refrigeration system is to transfer heat from the refrigerant to another medium, such as air and/or water. Of, pertaining to, producing, or produced by evaporation. c. an indication of the sensible heat content of the air 3-3: Term.

The purpose of an evaporative condenser is to condense high-pressure refrigerant vapor from the compressor to high-pressure liquid. Water flows through fill as a fan draws air across it, facilitating the transfer of heat from the warm water to the cooler air. Evaporative Condensers. What does evaporative mean? The colder water gets pumped back to the process/equipment that absorbs heat or the condenser. ‘evaporative water loss’. Evaporative Condensers. Evaporative condensers:- In an evaporative condenser, both air and water are employed as a condensing medium. Definition. As soon as you see old grease come out, stop or you could break the seal.” The evaporative condenser, as its name implies, 1 to change or cause to change from a liquid or solid state to a vapour Compare → boil 1 → 1 2 to lose or cause to lose liquid by vaporization leaving a more concentrated residue 3 to disappear or cause to disappear; fade away or cause to fade away The condenser is a heat exchanger which allows heat to migrate from the refrigerant gas to either water or air. Conditioning Process Definition. adjective. COP (Air cooled Condenser) COP (Evaporative Condenser) 1 1.25 1.59 2 1.48 1.56 3 1.61 1.735 COP improvement of air conditioning system using evaporative condenser When water scale is deposited on the heat transfer surfaces of an evaporative condenser, the cooling water from the spray heads cannot efficiently condense the refrigerant gas in the coils. This usually takes the form of grass clippings, fallen leaves, twigs, and pet hair that make it harder for the condenser to release heat. 38. By rejecting heat, the gaseous refrigerant condenses to liquid inside the condenser. The evaporative condenser integrates the cooling tower, condenser, circulating water tank, circulating water pump and water pipe, which reduces equipment such as cooling towers, circulating water pumps and water pipes, and reduces the handling and installation of individual components in the cooling tower/condenser system. By definition, stainless steel is a group of iron-based alloys which contain a minimum of 10.5% chromium.1 The stainless steel sheet material utilized by EVAPCO is Type 304 and Type 316 with a No. The air is being pulled by an motor-driven electric “cooling tower fan”.
