Abstract
Embodiments relate to heat exchanger contamination monitoring in an air conditioning system. An aspect includes receiving, by a contamination monitoring logic from a primary heat exchanger outlet temperature sensor, a first temperature comprising an air temperature at an outlet of a primary heat exchanger. Another aspect includes receiving, from a secondary heat exchanger outlet temperature sensor, a second temperature comprising an air temperature at an outlet of a secondary heat exchanger. Another aspect includes receiving, from a compressor outlet temperature sensor, a third temperature comprising an air temperature at an outlet of a compressor. Another aspect includes determining, based on the first, second, and third temperature, a heat exchanger contamination value. Another aspect includes comparing the heat exchanger contamination value to a predetermined contamination threshold. Another aspect includes based on the heat exchanger contamination value being greater than the predetermined contamination threshold, sending a maintenance warning.
