Patent number: 10180272Abstract: A system includes a compressor driven by a motor. A condenser receives working fluid from the compressor. An evaporator is in fluid communication with the condenser and the compressor. A first sensor produces a first signal, and a second sensor produces a second signal. A processing circuitry processes the first signal and the second signal to determine a new baseline freeze time. The processing circuitry determines the new baseline freeze time for a predetermined time following an installation event, a service event, or a power outage of the compressor.Type: GrantFiled: April 23, 2018Date of Patent: January 15, 2019Assignee: Emerson Climate Technologies, Inc.Inventors: Vijay Bahel, Kurt James Knapke

Patent number: 5689963Abstract: Compressor discharge temperature, ambient outdoor air temperature and thermal load are used as control parameters for controlling the expansion valve setting and indoor fan speed. Diagnostics monitor a feedback signal from the fan motor to detect fan over-speed and increased speed due to decreased air flow caused by a dirty indoor air filter. Discharge pressure of the compressor is monitored to detect a blocked outdoor fan. The difference between actual and optimum compressor discharge temperatures and suction pressure of the compressor are monitored to detect a stuck-closed expansion valve or low refrigerant charge. Compressor "short-cycling" is limited to prevent reduced reliability of the compressor. The difference between compressor discharge temperature and outdoor coil temperature is measured before and after startup to detect compressor failure.Type: GrantFiled: September 12, 1996Date of Patent: November 25, 1997Assignee: Copeland CorporationInventors: Vijay Bahel, Hank Millet, Mickey Hickey, Hung Pham, Gregory P.

Patent number: 5628201Abstract: Compressor discharge temperature, ambient outdoor air temperature and thermal load are used as control parameters for controlling the expansion valve setting and the indoor fan speed. In a variable capacity system the thermal load parameter also controls the compressor capacity. Thermal load is measured by an integrating procedure that increments or decrements an accumulated demand counter value used as an indication of thermal load on the system. The counter value is incremented and decremented based on the room temperature and thermostat setpoint. These same parameters are also used in the overcharge/undercharge diagnostic system.Type: GrantFiled: April 3, 1995Date of Patent: May 13, 1997Assignee: Copeland CorporationInventors: Vijay Bahel, Hank Millet, Mickey Hickey, Hung Pham, Gregory P.
