	Desuperheaters
	Doucette Industries manufactures a broad range of energy-saving desuperheaters that utilize refrigeration waste heat to warm potable water. Refrigerant desuperheater waste heat recovery systems can recycle rejected heat from your air conditioning or refrigeration system and use it to heat water or other fluids. At the same time, desuperheating lowers refrigerant temperature and pressure, reducing energy input to the compressor. You save be reducing or eliminating the energy required for water heating while increasing the efficiency of the air conditioning/ refrigeration system. In the refrigeration cycle, refrigerant is pumped from the compressor at high (150° to 200°+F) temperatures so that it can reject heat and condense to a liquid form. About 25% of this heat is called “superheat” and is easily recycled into lower temperature water. Water is pumped from a storage tank through the desuperheater and back to the tank (closed loop) adding heat to the water with each pass through the heat exchanger. This heat exchange results in increased efficiency for the refrigeration system while, at the same time, producing “free hot water”. Several factors will determine your actual savings. Hot water use, heating system efficiency and fuel cost, as well as cooling system size and run time, must be known in order to make accurate energy savings forecasts. As with any investment, a careful analysis should be made. However, with today’s energy costs, virtually any application with moderate to heavy cooling and water heating loads will yield attractive savings. Simple pay backs under two years are very common, yielding investment returns of 50% and more. Desuperheaters can be applied to any refrigeration system with reciprocating, rotary, scroll or screw-type compressors. Facilities such as motels, hotels, schools, hospitals, restaurants, health clubs and food processing are typical applications. Heating potable water for domestic use is most common. Applications for hot deck reheat, space heating, subsoil heating (freezer and ice rinks) and process fluid heating are very cost effective.
