Abstract
A method and apparatus for effecting capacity control of a compressor are described. A compressor having multiple capacity steps is utilized. A control valve being connected to both the compressor discharge pressure and the compressor suction pressure as well as heating and cooling pressure sensors is utilized. The control valve acts to connect appropriate pressure to the pressure sensors such that a variation in pressure level beyond a predetermined range effects a pressure sensor change indicating a need to change the capacity level of the compressor. Upon the capacity level of the compressor being changed the control valve is cycled to apply an opposite pressure level to the pressure sensor to reset the pressure sensor such that the pressure sensor may again detect a change in the pressure level to indicate a further need for a capacity change in the compressor.
