Problems solved by technology

For example, in a refrigeration or air-conditioning system equipped with multiple scroll compressors, abnormal vibration of a scroll compressor can cause the refrigeration tube of a single scroll compressor to rupture
A rupture of this tube will result in total loss of refrigerant in the system, impairing its performance, expensive repairs and in some cases dangerous

Embodiment Construction

[0029] Referring to the drawings, wherein like reference numerals indicate like or corresponding parts, in figure 1 and 2 Of these, a scroll compressor having the compressor protection and control subsystem of the present invention is generally indicated by reference numeral 10 . While the hermetic scroll compressor is used as an example to illustrate the compressor protection and control subsystem, it is within the scope of the invention to apply the compressor protection and control subsystem to other rotary compressors. Compressor 10 generally includes a cylindrical hermetic casing 12 having a cover 14 welded at its upper end and a bottom 16 at its lower end with a plurality of mounting feet (not shown) fitted thereto. The cover 14 has a refrigerant discharge connection 18 in which a conventional discharge valve (not shown) may be located. Other primary components attached to the shell include transversely extending bulkheads 22 . It is welded on the periphery of the she...

Abstract

A compressor protection and control subsystem for a rotary compressor provides temperature, pressure, mis-wiring and vibrational protection for the scroll machine. The vibrational protection comprises a vibration sensor which is integrated on the circuit board of the protection and control subsystem. The vibration sensor, in conjunction with at least one timer, monitors the vibrations of the scroll machine and will shut down the machine when excess vibrations are sensed over a prespecified period of time. The temperature system monitors operating temperature conditions the pressure system monitors operating pressures and the mis-wiring system monitors the power supplied to the compressor. Once an undesirable characteristic is identified, the operation of the scroll machine is stopped. These protection systems are integrated into a single subsystem which identifies the reason of shutting off the scroll machine in order to simplify repairs needed. The subsystem incorporates a gateway and / or a serial peripheral interface in order to communicate with a central operating and control system.

Description

technical field [0001] This application is a divisional application of the invention patent application No.01104886.7 filed on February 28, 2001, entitled "Compressor with Control and Protection System". [0002] The invention relates to the control and protection of compressors. In particular, the present invention relates to a compressor control and protection system that integrates compressor temperature control, phase protection, vibration protection, oil level control and protection, pressure sensing and pulse width modulation control. Background technique [0003] Scroll compressors are becoming more and more popular for use in refrigeration and air conditioning machines due to their very efficient operating capabilities. Typically, such machines have a pair of interlocking helical casings, one of which orbits relative to the other to form one or more moving chambers that step in size as they travel from the outer suction port towards the central discharge port. decr...
