But you don't want it to deadlocked, nor do you want to pay for the pumping energy. The amount of water required in a desuperheater depends on the amount of superheat or degrees of temperature that need to be lowered and depends on the pressure of the steam header. Som et resultat vil den tilgjengelige virkningsgraden multipliseres med den faktiske virkningsgraden og dette vil senke effektivitetsverdien. Denne prosessen utfres ved bruk av tempereringsvann som er hentet fra kondensatvannet. The hot water spray is maintained at a temperature close to the steam saturation temperature at the exit of the equipment. The rules differ as per the States, but the underlying fact remains that the utility company couldn't do it (intentionally). This cooled the hotter water at the top of the tank (and warmed the cooler water at the bottom of the tank) and made it seem like the desuperheater was stealing hot water from the tank, even though it wasn't. Videre er damptemperaturen ved utlpet av desuperheateren lavere enn fr. It is a result of cold water hitting the surface of hot bodies or metals or surfaces. The result is typically a 3% to 5% reduction in refrigeration operating costs, enhanced condenser performance and prolonged compressor life. 2. The heads should pop up and spit out water. A desuperheater is used for removing the heat that is present in the superheat thereby reducing the temperature of the superheat close to saturation temperature or below. Det kan beregnes ved bruke en entalpibalanse der summeringen av entalpien til damp og vann er lik varmen som er tilstede i utlpsstrmmen. For installing a desuperheater, it is essential to have a heat pump which is included in the total cost that is mentioned. The penetration of the spray droplets should be in the range of 15 to 85 percent of the tube diameter. Usually they turn the DSH pump off when source EWT is below 50F in cooling mode, or when the DSH EWT is less than 25F above the refrigerant temperature. One thing we noticed is when the geothermal system (and desuperheater) runs for short periods of time, it mixed the colder water at the bottom of the water heater with the hotter water at the top of the tank.
