    Abstract: 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.

    Abstract: A compressor may include first and second scrolls and a seal. The first scroll includes a first end plate and a first spiral wrap extending from the first end plate. The first end plate may define a discharge passage and an annular recess surrounding the discharge passage. The second scroll includes a second end plate and a second spiral wrap extending from the second end plate. The first and second spiral wraps cooperate to define a plurality of fluid pockets. The seal may be at least partially received in the annular recess and may cooperate with the first scroll to define a biasing chamber receiving fluid at an intermediate pressure. The seal may include inner and outer diametrical surfaces. The inner diametrical surface may include a plurality of first annular grooves. The outer diametrical surface may include a plurality of second annular grooves.

    Abstract: 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.

    Abstract: A compressor may include first and second scrolls, a hub plate and a valve. The first scroll may include an end plate defining first and second sides, a primary discharge passage extending therethrough, and a secondary discharge passage extending therethrough and located radially outward from the primary discharge passage. The hub plate may be mounted to the first scroll and may include first and second opposite sides and a hub discharge passage in fluid communication with the primary discharge passage. The first side of the hub plate may face the second side of the end plate and may include a valve guide extending axially toward the end plate adjacent the hub discharge passage. The valve member may be secured on the valve guide for axial movement between open and closed positions to respectively allow and restrict fluid communication between the secondary discharge passage and the hub discharge passage.

    Abstract: A compressor may include first and second scrolls, a seal assembly and a valve ring. The first scroll may include a first end plate having a discharge passage, a modulation port, and a biasing passage. The modulation port may be in communication with a first pocket formed between spiral wraps of the first and second scrolls. The biasing passage may be in communication with a second pocket formed between spiral wraps of the first and second scrolls. The modulation valve ring is axially displaceable relative to the seal assembly and the first scroll between first and second positions. The valve ring may abut an end plate of the first scroll and close the modulation port when in the first position. The valve ring may abut an axially-facing surface of the seal assembly and is spaced apart from the end plate to open the modulation port when in the second position.
