Refrigeration system analyzer
First Claim
1. Apparatus for automatically analyzing a refrigeration system of the type which includes a compressor, condenser and evaporator means having inputs and outputs interconnected by conduit means in a refrigerant loop, said apparatus comprising:
- means for reading temperature at a plurality of preselected points around said loop,means for comparing said temperature readings to each other and to predetermined standards, and for diagnosing a pluarlity of fault conditions as a function of such comparisons,means for displaying diagnosed fault condition,a temperature probe constructed for manual placement at each of said preselected points in turn, andan electronics and display package including said reading means, means for selectively storing each of said temperature readings in turn, said comparing means and said displaying means.

Abstract
Apparatus for analyzing air conditioning systems comprising a temperature probe adapted for manual placement at each of a plurality of preselected points in turn around the refrigerant loop to provide signals indicative of temperature at each point. Apparatus electronics are coupled by a cable to the temperature probe and includes facility for reading and storing each of the probe temperature measurements in turn. Information indicative of standards and ranges of temperature data for properly operating refrigeration systems of a number of models and manufacturers is prestored in apparatus memory. The system temperature readings are compared to each other and to the prestored data to diagnose a plurality of fault conditions and to display diagnosed fault conditions to an operator.
