Definitions

  • This invention relates to an ice bank control system, and in particular to such a system for a beverage dispenser having a mechanical refrigeration system.
  • the present invention encompasses more than just controlling the thickness of the ice bank; it also includes protection for the compressor.
  • the present invention uses a solid state sensor that has proven to be very reliable to measure the temperature of the super cooled ice. This system can maintain a very consistent ice bank within the capacity of the compressor system.
  • the ice bank control system of this invention is for use in a mechanical refrigeration system of a beverage dispenser, and comprises a sensor (or probe) located in the ice water bath tank adjacent to the evaporator coil, a control circuit including a microprocessor located above the ice water bath tank, and a low cost relay for turning the compressor on and off.
  • the sensor is an inexpensive solid state sensor, preferably a thermistor.
  • the microprocessor is preferably a single chip microcomputer.
  • the microprocessor is programmed to not only control the ice bank, but also to: (1) maintain the compressor off for a period of time, each time it is turned off, to allow high and low pressure equalization to reduce the risk of compressor motor burnup; (2) shut off the compressor to prevent an overfreeze whenever either a short circuit or an open circuit occurs in the solid state sensor; (3) control the agitator motor including keeping it off whenever the water temperature is above a certain temperature, such as 40 degrees F (4.4°C), to reduce the risk of burnup of the compressor motor; (4) prevent overbuild of the ice bank during the initial icebank buildup, which can prevent freeze up of the syrup and water lines; (5) reduce the number of calls required to repair a failure; and (6) provide a "watchdog" circuit that turns the compressor off in the event of an unusual spike or wave form.
  • Fig. 1 shows a beverage dispenser 10 having a mechanical refrigeration system 12 including an ice water bath tank 14, evaporator coils 16 positioning in the tank 14 to build an ice bank 17, syrup cooling coils 18, water cooling coils 19, an agitator 20, an agitator motor 22, a compressor system including a compressor motor 24 and a control box 26 housing an ice bank control system 28.
  • the ice bank control system 28 of the present invention can be used with any standard well-known refrigeration system. It is therefore, not necessary to describe in detail such known refrigeration system.
  • the ice bank control system 28 of this invention comprises a sensor 30 connected by an insulated and shielded electrical line 32 to the ice bank control system mounted above the water on a refrigeration deck 36.
  • the sensor 30 is mounted in the ice water bath at the desired predetermined distance (usually one to two inches (25-50mm)) from the evaporator coil 16, by a support bracket 38 connected to a turn of the coil. The distance depends upon the type and size of the particular dispenser, the amount of weight of ice the coils 16 are designed to carry, and the desired thickness of the ice bank.
  • the bracket 38 can provide for adjusting the distance of the sensor 30 from the coil.
  • the sensor 30 is preferably an inexpensive solid state sensor such as a highly repeatable thermistor sensing element 40 encased in a quantity of epoxy material 42 inside a watertight plastic (preferably Lexan) shell 44.
  • the sensor 30 is preferably placed at the desired location for the boundary between the ice and the water.
  • the ice bank would vary in size from about one inch (25mm) beyond the sensor to one inch (25mm) short of the sensor.
  • the present invention keeps the ice bank at essentially the same size all the time.
  • the temperature at the sensor will continually drop, and while the compressor is off, the temperature at the sensor will continually increase.
  • Various selected temperatures can be selected for the sensor to turn the compressor off and on, that is, at a first temperature and a second higher temperature, respec­tively.
  • a preferred first temperature is 29.5°F (-1.4°C) for all but the first pulldown cycle (which is 27°F (-2.8°C)), and is preferably 31.5°F (-0.3°C) for the second temperature.
  • Fig. 4 shows in block diagram the ice bank control circuit 34 connected to the sensor 30.
  • the ice bank control circuit 34 is connected to both the agitator motor 22 and to the compressor motor 24.
  • Fig. 5 is a more detailed electrical schematic diagram of the ice bank control circuit 34, which diagram has been divided up by dotted lines into seven separate sections A-G for ease of description.
  • the power supply converts 24 VAC into 24 VDC to supply the relays and into regulated 5 VDC to supply the analog and digital logic circuits.
  • MV1 is a varistor which protects the circuitry in the event that more than 47 volts is applied.
  • Capacitors CE7 and CE8 provide a voltage drop for the AC voltage to the bridge rectifier BR1.
  • the output of the bridge is preregulated by resistor R2 and Zenerdiode DZ1 and filtered by capacitor CE5.
  • This voltage is the input to regulator RG1 which provides +5 VDC to all the analog and logic circuitry.
  • Diode D1 rectifies the AC input voltage to provide 24 VDC.
  • Resistor R12 limits the current to the relays.
  • integrated circuit I1 is a complete 8 bit single chip microcomputer 48 with 512 program steps and 32 bytes of RAM. It has an 8 bit counter and 12 input/output pins. Inductor L1 and capacitors C3, C4 provide a 4 MHz resonator to the oscillator inputs of the microcomputer. J1, J2, J3, J4, J5, J6, and J7 are wire jumpers which are connected between I/O pins on the microcomputer and ground. Some of the wires will be cut during calibration to one of 128 different patterns.
  • this is a watchdog timer circuit that provides power-on reset for the microcomputer and monitors the operation, forcing the microcomputer to reset if it detects the output pin not changing "states" for as long as eight seconds.
  • Capacitors C15, diode D5, and resistor R15 differ­entiate the watchdog strobe output of the microcomputer 48, which is implemented with software and an output pin. This signal is buffered with one of the gates of integrated circuit 14 and is the input trigger for an 8 second retriggerable timer made up by diode D6, resistor R14, and capacitor CE6.
  • the timer times out, and the output of the timer is the input gate signal to a gated oscillator made up of capacitor CE2, resistor R3, and one of the gates of 14.
  • a gated oscillator made up of capacitor CE2, resistor R3, and one of the gates of 14.
  • this compressor control circuit takes the logic level output of the microcomputer 48 and drives a normally open dry contact relay output.
  • the microcomputer outputs a logic "1" to open the contacts and a logic “0" to close the contacts.
  • Transistor Q3 and resistors R16 and R8 invert the logic output.
  • Capacitor CE3 filters the output of the inverter to keep the relay off during transients.
  • Darlington transistor Q1 drives the coil of RL1.
  • Diode D2 protects the circuitry from the inductive switching transients.
  • Resistor R17 and capacitor C16 provide damping for the contacts of the relay during switching.
  • this agitator control circuit takes the logic level output of the microcomputer 48 and drives a normally closed dry contact relay output.
  • the microcomputer outputs a logic "1" to open the contacts and a logic “0" to close the contacts.
  • Darlington transistor Q4 and resistor R18 drive the coil of relay RL2.
  • Diode D7 protects the circuitry from the inductive switching transients.
  • this precision oscillator changes the output wave form with changes in the resistance of the sensor input.
  • the output wave form is analyzed by the microcomputer 48 to obtain temperature and component drift information.
  • the circuit generates a wave form of which one part is proportional to the temperature, and one part is proportional to a reference.
  • Resistors R7, R10, and R11 form a precision voltage divider with outputs of 1.67 VDC and 3.33 VDC.
  • Capacitors C2 and C6 filter the outputs of the divider which are input to two precision analog voltage comparators contained in integrated circuit 12. The comparators are connected in a circuit where if the voltage of the other inputs to the comparators is between 1.67 and 3.33 VDC the outputs of the comparator are logic "1".
  • Resistors R1 and R4 are pullups for the comparators. If the voltage of the other inputs becomes greater than 3.33 or less than 1.67, the output of one of the comparators will be "0".
  • the comparator outputs are the set and reset inputs for a "nand latch” made up of two gates of 14. When the voltage exceeds the boundaries set up by the voltage divider, the nand latch will change states.
  • One output of the nand latch is input to the microcomputer 48.
  • the other output drives switching transistor Q2 through resistor R9.
  • the other input to the comparators is the voltage on capacitor CE4, which will be charging or discharging through resistor R6 depending on the state of Q2.
  • T1 is a negative temperature coefficient thermistor whose resistance changes with temperature in a repeatable manner.
  • the system of the present invention includes a low cost highly repeatable thermistor sensing element 40 coupled with a single chip microcomputer 48 to control temperature within .05 degrees F (0.03°C) over a very narrow temperature span extending from about 29.5 to about 31.845 degrees F(-1.4 to 0.086°C).
  • the thermistor 40 was selected because it maintained a Beta curve of plus or minus 1.2% at a temperature range near 32 degrees F (0°C), which variation is almost negligible over the narrow span at the near freezing temperature range within which we are operating.
  • thermistors are used measuring voltage across a resistive divider and converging to digital values using a discrete or monolithic analog-to-digital converter.
  • the thermistor as one component of a two resistor, one capacitor oscillator.
  • the time of the low state of the oscillator is dependent only on the values of a fixed resistor R6 and the capacitor CE4.
  • the time of the high state of the oscillator is dependent on the values of the thermistor 40 resistance, the fixed resistor R6 and the capacitor CE4.
  • Time Low K x RF x C
  • Time High K x (RF + RT) x C
  • RF Value of Fixed Resistor
  • K Constant
  • the value of the capacitor is not used in the calculation of the RT, the value of the capacitor and any temperature drift is not too critical.
  • the temperature drift of the fixed resistor is specified to be negligible.
  • the microcomputer 48 measures the periods and computes the temperature.
  • the thermistor 40 is much like other temperature sensors in that they typically, in a single thermistor version, do not have a linear output that coincides with a linear temperature line.
  • the resistance output is a curve which has to be compensated for in order to have accurate measurements.
  • microprocessor 48 Since the microprocessor 48 has control of the relay (switch RL1 in Fig. 5D) that controls the compressor motor 24 and since it has the capability of sensing other temperatures and timing functions, we included in the software the following features to further enhance the capability of the icebank control system 28 of this invention:
  • the single chip microcomputer 48 is a General Instrument PIC 1654. Some notable characteristics of the microcomputer are:
  • the program consists of 1 main program routine, 6 subroutines, and 7 floating point math subroutines.
  • NORM normalizes a floating point number in B so that its most significant bit in the mantissa is a 1.
  • FSWAP exchanges the contents of floating point registers A and B.
  • FIXA repairs the mantissa of floating point register A with regard to the counting scheme used by period, period counts within a 16 bit pseudoregister but the upper B bits has the value of 128 not 256 as with a normal 16 bit number. FIXA divides the upper 8 bits by 2, then adds 128 to the bottom 8 bits if the top 8 was not evenly divisible by 2.
  • movbw moves a floating point number in floating register B to the floating point register whose number is in W at the onset of the CALL.
  • movwb moves a floating point number whose file number is in W at the onset of the CALL to floating point register B.
  • wdt prevents the constant re-initialization of the microprocessor by the watchdog hardware, during normal operation. It does this by toggling the wdog line whenever called. The resulting pulses keep capacitor CE6 discharged, thus preventing the connected section of IC2 from oscillating and resetting the 1654 microcomputer 48.
  • This section does simple initialization then delays for 2.2 seconds or 4.5 minutes (test or normal modes).
  • This section takes 128 samples, calculates the resistance of each individually and keeps a running sum.
  • A, B, and C are the constants 86.979, .0226819, and 17.9 E-9 which were derived from a 2nd degree polynomial fitting the resistance curve between -5 and +5 degrees Celsius.
  • hitest first checks to see whether the temperature is below 40 degrees F (4.4°C). If it is, it turns on the stirrer motor. The high setpoint is then loaded.
  • hiO checks the current temperature against the high setpoint. If it is less than the setpoint program flow continues at lotest. Otherwise the current temperature is compared to 150 degrees Fahrenheit (66°C). If the temperature is greater than 150, we restart by sitting in a loop and not allowing the watch dog timer to be pulsed. The program continues by going to MAIN.
  • loO compares the low setpoint against the current temperature. If the current temperature is above the low setpoint then the program continues with2. If the current temperature is less than the low [test] setpoint then the relay is turned or left on. The program continues by going to MAIN if in test mode.
  • the program waits for 4.5 minutes to prevent the compressor from immediately turning back on, then continues at MAIN.
  • pbody acts in two ways. When first called it synchronizes the program with the temperature period. When called again it returns the actual values of the high and low times.
  • Lines 1 through 278 perform the floating point mathematical operations of addition, subtraction, multiplication, and division.
  • the mantissa is a 16 bit long 2's complement representation of a number between -1/32,768 and 1/32,768.
  • the exponent is an 8 bit two's complement representation of a number between -128 and 128. This provides a working range of numbers from positive or negative 2.9x10 ⁇ -39 to positive or negative 3.4x10 ⁇ 38 with an accuracy exceeding 4 significant decimal digits.
