Permanent low cost radio frequency compressor identification

Abstract

A sealed compressor assembly has a compressor and a housing enclosing the compressor. The housing for the compressor has a receiver and a memory unit. The receiver receives a first signal, which is stored on a memory unit on the housing.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to an apparatus for remotely storing and retrieving data from a compressor. [0002] Refrigeration systems frequently use a compressor to compress refrigerant as part of a refrigeration cycle. Modern compressors are typically enclosed in a sealed housing, which also houses a motor that drives the pump unit. The motor may be driven by a single phase or three phase power supply. [0003] Compressors operate under many extreme conditions. Consequently, some compressors have relatively complex operational parts. In one popular modern type compressor, the pump unit includes two spiral scroll wraps which orbit relative to each other to compress entrapped refrigerant. These scroll-type compressors are gaining in popularity. [0004] Compressors, such as scroll compressors, are generally mass produced. While each compressor may conform to the same specifications, they may vary within tolerances of the specifications. Consequently, compress...

Benefits of technology

[0010] In addition, the inventive compressor assembly may have a transmitter, which is also controlled by the microprocessor. The transmitter serves to communicate information stored on the memory unit to allow remote access of this information. This feature permits information to be stored at the compressor while still being written and read from a distance from the compressor.

[0012] The information may be communicated to the receiver and transmitted by the transmitter by an electric signal, such as a radio frequency signal. Accordingly, a device having another receiver and another transmitter may communicate with the memory unit on the compressor. In this way, information may be downloaded and retrieved from the memory unit of the compressor by a remote unit, such as a handheld device. This feature permits the quick reading and writing of information to the memory unit of the compressor.

Problems solved by technology

Consequently, some compressors have relatively complex operational parts.

Moreover, each compressor may be shipped to different locations and be used in different operating environments, thereby causing each compressor to be subject to differing amounts and types of wear.

This additional step may be time consuming.

Such a system for storing and retrieving information may be inconvenient when dealing with large numbers of compressors as each jack of each compressor must be accessed to obtain this information.
