YORK’s early Turbopaks could be furnished with an acoustic enclosure if a customer wanted an enclosure. If you use a 680 Ohm resistor in the control (thermostat) circuit, the motor speed will just be a little less than 3,000 rpm. Opening the failed compressor page 3 3. In hermetic and most semi-hermetic compressors, the compressor and motor driving the compressor are integrated, and operate within the pressurized gas envelope of the system. However, the change of load condition causes the moving parts of compressor and the refrigerant to operate unsteadily, which leads to large deviation when the traditional speed measurement method is used. hermetic motor-compressor has been developed, and is widely used in small horsepower unitary equipment. Based on the above mechanism, the DEZ first eliminates the trend component of pressure pulsation, then extracts the feature component, and finally calculates the exact rotational frequency by spectrum zooming.
