Abstract:
1. A climate control system having a high pressure side and a low pressure side, wherein a fluid flowing through the climate control system changes state between a vapor state and a liquid state to provide climate control, the climate control system comprising: a compressor being operable to compress a fluid at a low pressure to a high pressure, the compressor comprising an inlet portion to receive fluid at a low pressure from a low pressure side of the system, a compression chamber for compression of fluid, and an outlet portion to provide fluid at a high pressure to a high pressure side of the system; and a pressure equalization system operatively connected to the compressor, the pressure equalization system being configured to equalize pressure between the inlet portion and the outlet portion of the compressor in response to the compressor not being in operation, the pressure equalization system comprising: wherein the piston being positioned in the first position in the chamber in response to the compressor being in operation, and the piston being positioned in the second position in the chamber in response to the compressor not being in operation, the piston being movable between the first position and the second position by a fluid force differential between the first inlet connection and the second inlet connection, thereby permitting fluid at a high pressure to flow through the first inlet connection to the first outlet connection to equalize pressure in the compressor when the compressor is not operating.
