Compressor diagnostic and recording system
First Claim
1. A sealed compressor comprising:
- a housing enclosing a compressor pump unit and a motor for driving said compressor pump unit;
a microprocessor control for determining fault conditions, said control being provided with data with regard to several operational features of said compressor, and said control storing said data in a memory, said control and said memory being mounted on an inner surface of said housing, and being accessible to a worker to retrieve said data at a later point in time.

Abstract
A compressor diagnostic system incorporates a control which receives a plurality of data streams about various operational features of the compressor. As an example, both temperature and pressure of the suction and discharge refrigerant are taken and sent to the control. Moreover, information with regard to the power being supplied to the motor is taken and stored. All of this information is utilized at a control which compares the information to expected values and determines a fault based upon the evaluation. Moreover, in another feature of this invention, much of this data is stored, and maintained at the compressor. In the event of a compressor failure, this stored information will provide a maintenance worker with a good indication of why the compressor failed.
