摘要： A climate-control system may include a variable-capacity compressor unit and a control module controlling the compressor unit. The compressor unit may be operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode. The control module may be configured to switch the compressor unit among a shutdown state, the first capacity mode and the second capacity mode based on a demand signal and outdoor-air-temperature data.

摘要： A climate-control system includes a variable-capacity compressor unit and a control module. The variable-capacity compressor unit is operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode. The control module may be configured to switch the variable-capacity compressor unit between the first capacity mode and the second capacity mode based on a demand signal, a current outdoor air temperature, an outdoor-air-temperature slope, and a previous runtime of the variable-capacity compressor unit in the second capacity mode.

摘要： A working-fluid circuit may include an indoor heat exchanger, a variable-capacity compressor and a control module. The variable-capacity compressor pumps working fluid through the indoor heat exchanger. The control module may control the compressor and operate the compressor in one of a first capacity mode and a second capacity mode based on a demand signal, outdoor-air-temperature data and a compressor runtime.

摘要： A system includes a variable-capacity compressor operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode. A control module is configured to switch the variable-capacity compressor between the first capacity mode and the second capacity mode based on a demand signal from the thermostat. The control module determines a number of previous consecutive operating cycles of the variable-capacity compressor in the first capacity mode within a predetermined period of time. The control module operates the variable-capacity compressor in the second capacity mode in response to the number of previous consecutive operating cycles of the variable-capacity in the first capacity mode within the predetermined period of time exceeding a predetermined threshold.

摘要： A climate-control system includes a variable-capacity compressor unit operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode and a control module configured to (i) switch the variable-capacity compressor unit between the first capacity mode and the second capacity mode based on a demand signal, a current outdoor air temperature, and an outdoor-air-temperature slope, (ii) select a region based on a first comparison of at least one outdoor-air-temperature value with a predetermined outdoor-air-temperature range and a second comparison of at least one outdoor-relative-humidity value with a predetermined outdoor-relative-humidity range, and (iii) set at least one system operating parameter based on the selected region, the at least one system operating parameter including at least one of a high-capacity runtime of the variable-capacity compressor unit, a low-capacity runtime of the variable-capacity compressor unit, and a fan speed.

摘要： A system includes a variable-capacity compressor operable at a first capacity and at a second capacity that is higher than the first capacity and an outdoor-air-temperature sensor. A control module receives a demand signal from a thermostat and operates the variable-capacity compressor in a first mode when communication with the outdoor-air-temperature sensor has not been interrupted and in a fault mode when communication with the outdoor-air-temperature sensor has been interrupted. In the first mode, the control module switches the variable-capacity compressor between the first capacity and the second capacity based on the demand signal and the outdoor-air-temperature data. In the fault mode, the control module operates the variable-capacity compressor by operating the variable-capacity compressor at at least one of the first capacity and the second capacity based on the demand signal.

摘要： Systems and methods are provided and include a variable-capacity compressor operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode. A control module is configured to switch the variable-capacity compressor between the first capacity mode and the second capacity mode based on a demand signal from a thermostat and an indoor relative humidity sensed by an indoor relative humidity sensor. The control module determines whether the indoor relative humidity is greater than a predetermined humidity and operates the variable-capacity compressor in the second capacity mode in response to receiving the demand signal from the thermostat and the indoor relative humidity exceeding the predetermined humidity.

摘要： A system includes a converter and a controller to control a compressor and operates without receiving power supply from a thermostat. The converter receives a demand signal from the thermostat that is used to power the controller and charge a capacitor. When the thermostat de-asserts the demand signal, the charged capacitor powers the controller, which saves system parameters in a nonvolatile memory and enters a power save mode. The life of the nonvolatile memory is extended by alternately storing the system parameters in different memory locations. The system normalizes outdoor ambient temperature (OAT) during a demand cycle. The system determines OAT slope, which is used to select durations to operate the compressor at different capacities, by performing time based calculations during a demand cycle, demand cycle based calculations at the start of a demand cycle, or time and demand cycle based calculations during a demand cycle.
