Description

Background Technology

[0001] This disclosure relates to the control of systems used for heating and / or ventilation and / or air conditioning (HVAC). More specifically, this disclosure relates to the current supplied to actuators and / or motors of such systems.

[0002] Installations for heating and / or ventilation and / or air conditioning typically consist of multiple circuits. Each circuit includes one or more terminal units to provide heating and / or cooling to various parts of the building. Terminal units can be heating and / or cooling devices. In residential heating systems, terminal units can be heat exchangers, such as radiators.

[0003] HVAC installations, such as those for air conditioning, can also include one or more refrigerant circuits. These refrigerant circuits consist of a compressor, evaporator, expansion valve, and condenser. The compressor, evaporator, expansion valve (such as an electronic expansion valve), and condenser are connected in series to form the refrigerant circuit. Additional sensors, such as temperature sensors, pressure sensors, and power meters, can be provided to monitor and control the circuit's operation.

[0004] Stepper motors are frequently used to control flow through such loops. More specifically, a stepper motor positions a valve within the loop, thereby controlling the flow through the valve and ultimately through the loop. A driver circuit connected to a controller can be used to supply current to this stepper motor.

[0005] A large amount of refrigerant, such as -ammonia, -1,1,1,2-Tetrafluoroethane (R-134a) - Difluoromethane (R-32) It can circulate in the refrigerant loop of systems used for heating and / or ventilation and / or air conditioning. These refrigerants differ in their global warming potential. While ammonia is known to have zero or limited global warming potential, the global warming potential of 1,1,1,2-tetrafluoroethane is enormous. The global warming potential of 1,1,1,2-tetrafluoroethane compared to carbon dioxide is estimated to be 1430 or more. That is, one kilogram of 1,1,1,2-tetrafluoroethane has a global warming potential exceeding that of 1.4 tons of carbon dioxide. In other words, a leak of one kilogram of 1,1,1,2-tetrafluoroethane (R-134a) has roughly the same environmental impact as a passenger vehicle traveling 5,500 kilometers.

[0006] Compared to 1,1,1,2-tetrafluoroethane, difluoromethane (R-32) has limited global warming potential. However, the use of difluoromethane (R-32) in refrigerant circuits requires greater mechanical force when switching valves in these circuits. Therefore, more powerful stepper motors are employed to accommodate the increased mechanical force and / or torque.

[0007] More powerful stepper motors result in a greater current being supplied to them. When this current is supplied by driver circuitry, driver circuitry with higher ratings will be required. However, driver circuitry is difficult to upgrade or replace. Driver circuitry can be permanently integrated into systems used for heating and / or ventilation and / or air conditioning. Furthermore, upgrading or replacing such circuitry may involve design changes to the entire system used to control heating and / or ventilation and / or air conditioning.

[0008] Patent US3787727A was published on January 22, 1974. Application 05 / 319,100 for patent US3787727A was filed on December 27, 1972. US3787727A relates to stepper motor control.

[0009] Table 1 of US3787727A shows that more than one winding of the stator can be energized at a time. For this purpose, the circuit can energize two output conductors N, E, S, and W simultaneously. In the first step, only conductor N is energized. In the second step, the additional output conductor E is energized. That is, in the second step, both output conductors N and E are energized. In this way, the amount of torque applied by the stepper motor is controlled. More specifically, the amount of torque applied during start-up and stop is controlled. Therefore, problems caused by overshoot or hunting are mitigated.

[0010] This disclosure relates to a system for heating and / or ventilation and / or air conditioning, which controls two or more (stepper) motors. The (stepper) motors are controlled such that only a limited number of stator windings of these motors are energized at a time. By limiting the number of energized stator windings, the peak current supplied by the driver circuit is also limited. Summary of the Invention

[0017] Each of the first and second stepper motors may have four windings. Ideally, each of the first and second stepper motors may have four windings. Half-step excitation is also advantageously applied to the fourth winding of the first and second stepper motors.

[0018] When the motor is connected in a star configuration, a half-step excitation can be applied. Ideally, a half-step excitation can be applied when the stepper motor is connected in a star configuration.

[0019] When the motor is delta-connected or equivalently connected, a half-step excitation can be applied. Ideally, a half-step excitation can be applied when the stepper motor is delta-connected or equivalently connected. Attached Figure Description

The DAC provides the conversion of digital signals originating from controller 3a into analog signals. As a non-limiting example, the analog signal can be amplified to control one or more (stepper) motors.

[0048] The digital-to-analog converter (DAC) can be a component of the driver circuit 4a. That is, the DAC and the driver circuit 4a are arranged on the same system-on-a-chip. More specifically, the microcontrollers of the DAC and the driver circuit 4a are arranged on the same system-on-a-chip. It is also envisioned that the microprocessors of the DAC and the driver circuit 4a are arranged on the same system-on-a-chip.

[0049] The driver circuit 4a may also include a balancer. The balancer is operable to manage the load and / or phase shift of any motor connected to the driver circuit 4a, such as a (stepping) motor. More specifically, the balancer is operable to set the phase of signals sent to the windings of the first and second motors. The balancer can change the phase of the signal sent to the windings of the second motor. This first phase shift occurs relative to those phases of the signal sent to the windings of the first motor. The balancer can also change the phase of the signal sent to the windings of the first motor. This second phase shift occurs relative to those phases of the signal sent to the windings of the second motor.

[0050] Preferably, the balancer is included by either the controller 3a or the driver circuit 4a. Therefore, there exists a single balancer arranged in a component selected from the controller 3a and the driver circuit 4a.

[0051] The driver circuit 4a may be a component of the controller 3a. That is, the driver circuit 4a and the controller 3a are arranged on the same system-on-a-chip.

[0074] Figure 5 A conventional excitation is illustrated. The conventional cycle of the electrical signals applied to the first motors 5a-5d and the second motors 6a-6d is shown. The electrical signals applied to the first motors 5a-5d and the second motors 6a-6d can be current or voltage.

[0075] The first regular cycle 7a corresponds to the first motor 5a-5d. That is, the electrical signal according to the first regular cycle 7a is sent to the first motor 5a-5d. The second regular cycle 7b corresponds to the second motor 6a-6d. That is, the electrical signal according to the second regular cycle 7b is sent to the second motor 6a-6d.

[0076] Assume the first motor 5a-5d has four windings N, E, S, and W. Therefore, the signal sequence for the first regular cycle 7a of the windings of the first motor 5a-5d is labeled 50n, 50e, 50s, and 50w. Also assume the second motor 6a-6d has four windings N, E, S, and W. Therefore, the signal sequence for the second regular cycle 8a of the windings of the second motor 6a-6d is labeled 60n, 60e, 60s, and 60w.

[0077] At the beginning, an electric high signal is applied to the N winding of the first motor 5a-5d. The electric high signal is applied for two regular time intervals. As a non-limiting example, the electric high signal can be a voltage, such as 3.3 volts, 5 volts, or 12 volts. As another non-limiting example, the electric high signal can be a current, such as 100 mA, 200 mA, or 500 mA.
