Abstract
A thermistor is employed for sensing refrigerant temperature in a refrigeration system and an electronic controller continuously measures changes in resistance of the thermistor as an indication of refrigerant temperature for generating a control signal for controlling compressor clutch and condenser for the thermistor is calibrated at installation by flowing constant temperature air over the thermistor, measuring the resistance of the thermistor, comparing the measured value with a standard value and storing the comparison in the microcomputer non-volatile memory or externally such as non-volatile memory, diodes, program PINS, etc. as correction factor for operational use in controlling the system with refrigerant flowing over the thermistor.
