HEAT EXCHANGER CONTAMINATION MONITORING
First Claim
1. A method for heat exchanger contamination monitoring in an air conditioning system, the method comprising:
- 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 of the air conditioning system;
receiving, by the contamination monitoring logic from a secondary heat exchanger outlet temperature sensor, a second temperature comprising an air temperature at an outlet of a secondary heat exchanger of the air conditioning system;
receiving, by the contamination monitoring logic from a compressor outlet temperature sensor, a third temperature comprising an air temperature at an outlet of a compressor of the air conditioning system, wherein the compressor receives airflow from the outlet of the primary heat exchanger, and wherein the secondary heat exchanger receives airflow from the outlet of the compressor;
determining, by the contamination monitoring logic, based on the first temperature, the second temperature, and the third temperature, a heat exchanger contamination value;
comparing the heat exchanger contamination value to a predetermined contamination threshold;
based on the heat exchanger contamination value being greater than the predetermined contamination threshold, sending a maintenance warning to an operator of the air conditioning system.
