Method For Sensing The Liquid Level In A Compressor

View page
US Patent:
7874724, Jan 25, 2011
Filed:
Apr 11, 2007
Appl. No.:
11/786344
Inventors:
Ronald W. Okoren - Holmen WI, US
Jerry E. Brown - La Crosse WI, US
Joel C. VanderZee - La Crosse WI, US
Charles E. Nelson - Coon Valley WI, US
Steven K. Klingemann - West Salem WI, US
Jeffrey J. DeGroot - Onalaska WI, US
Assignee:
Trane International Inc. - Piscataway NJ
International Classification:
G01K 13/02
G01K 17/06
G01K 1/20
G01N 25/00
G01F 1/00
US Classification:
374 54, 374141, 374 29, 374135, 374152, 374 16, 374 1, 374173, 732045, 73 173, 73 116, 73292
Abstract:
Two vertically offset thermistors for sensing a fluid such as oil and refrigerant in a compressor shell are monitored by a method that takes into account rapidly changing conditions within the shell. The system can determine the fluid's sump temperature, high/low liquid levels, and can determine whether the thermistors are sensing the fluid as a liquid, gas, or a mixture of the two, such as a foam or mist of liquid and gas. For greater accuracy, thermistor readings can be dithered and filtered to provide temperature or voltage values having more significant digits than the readings originally processed through a limited-bit A/D converter. For faster response, limited microprocessor time is conserved by sampling thermistor readings at strategic periods that enable the microprocessor to identify certain conditions and temperatures via simple delta-temperature ratios and undemanding equations rather than resorting to exponential functions or lookup tables to determine time constants.

Variable Evaporator Water Flow Compensation For Leaving Water Temperature Control

View page
US Patent:
8132420, Mar 13, 2012
Filed:
Nov 7, 2008
Appl. No.:
12/291244
Inventors:
Ronald W. Okoren - Holmen WI, US
Joel C. VanderZee - La Crosse WI, US
Assignee:
Trane International Inc. - Piscataway NJ
International Classification:
F25D 17/00
US Classification:
62180, 622383, 62476
Abstract:
A method of controlling a refrigerant chiller system is particularly suited for chillers where the water being chilled (or some other liquid) flows through the chiller's evaporator at a flow rate that is variable and is not directly known. To effectively control the chiller and maintain the temperature of the water leaving the evaporator at a desired target temperature, the cooling capacity of the chiller's evaporator is estimated based the degree of valve opening of an expansion valve, a pressure differential across the expansion valve, and a change in enthalpy per unit mass of the refrigerant flowing through the evaporator. In some embodiments, the chiller system includes multiple refrigerant circuits that are hermetically isolated from each other.

International Classification:
G01F 1300
US Classification:
7386141
Abstract:
A sensor system. The system comprises a binary sensor issuing a signal representative of a first or second condition; sampling circuitry, operatively connected to the binary sensor, for monitoring the number of transitions between the first and second conditions during a sampling period; integration circuitry for accumulating the sampled number of transitions over time; and signal generation circuitry for issuing an analog signal representative of the accumulated transitions.

US Patent:
59504439, Sep 14, 1999
Filed:
Aug 8, 1997
Appl. No.:
8/910957
Inventors:
Jonathan M. Meyer - Onalaska WI
Ronald W. Okoren - Holmen WI
Lee L. Sibik - Onalaska WI
Daniel C. Leaver - La Crosse WI
Sean A. Smith - La Crosse WI
Assignee:
American Standard Inc. - Piscataway NJ
International Classification:
F25B 100
US Classification:
622285
Abstract:
A method of controlling compressor minimum capacity. The method comprises the steps of: measuring a first condition; comparing the first condition to a first setpoint to determine a first conditioned error; modulating compressor capacity relative to the first condition error; measuring a second condition; comparing the second condition to a second setpoint to determine a second condition error; and modulating compressor capacity relative to the second condition error if the magnitude of the second conditioned error is greater than the magnitude of the first conditioned error.
