HEAT TRANSFORMER (HEAT PUMP – TYPE II) )

Heat transformer also known as Type-II heat pump, in which medium grade heat is pumped to high grade heat. With a heat transformer, waste heat can be upgraded, virtually without the use of high temperature driving energy. The input heat source i.e., Waste heat of a medium temperature is supplied to the evaporator and generator and useful heat of higher temperature is given off in the absorber. These heat transformers can achieve a delivery temperature up to 160ºC, typically with a lift of 50ºC.
Heat Pumps, Heating Applications, Heat transformer, Thermax heat pumps utilise steam, hot water, exhaust, fuel, geothermal energy
Thermax has commissioned a Heat transformer at M/s. Asia Silicon in Western part of China. The plant manufactures poly film for photovoltaic cells and the process requires water at 100ºC. During the process this water temperature increases to 108ºC and for reutilization, the 108ºC water leaving the process was cooled to 100ºC in a dry cooler where the heat was simply rejected to the atmosphere. Using the Heat Transformer, 45% of the available heat is converted to steam at 4bar.g, which finds use in the manufacturing process.
