<\/i>It is the smallest difference between the temperatures of the cold and hot streams. For example, if you heat a cold fluid from 80°C up to 100°C using a hot fluid at 105°C, the approach temperature of the heat exchanger is 105-100 = 5°C. The lower approach, the higher heating area. <\/b>Thus, it is the difference in temperature between the cooling medium inlet temperature and the process fluid discharge temperature. <\/p>\n

    Air compressor’s approach temperature is how effectively the coolers will cool the compressed air before discharging to the main plant piping. The approach temperature<\/em> is a reference point on how close the compressed air discharge temperature is to the ambient temperature. Most air-cooled compressors have an approach to ambient temperature listed as 10°F (-12°C), 15°F (-9.4°C), or higher; it all depends on the size of the compressor and the rated design conditions. The stated approach temperature is most likely at the cooler design conditions, not the actual conditions. <\/p>\n","protected":false},"excerpt":{"rendered":"
