Claim 5:
6. The heat-pump system of claim 5, further comprising:
a first bypass flow path in selective fluid communication with the first and second reversing valves;
a first bypass valve fluidly connected to the first bypass flow path and movable between a first position in which fluid flow through the first bypass flow path is restricted and fluid flow to a suction inlet of the compressor is allowed and a second position in which fluid flow through the first bypass flow path is allowed and fluid flow to the suction inlet of the compressor is restricted;
a second bypass flow path in selective fluid communication with the first and second reversing valves; and
a second bypass valve fluidly connected to the second bypass flow path and movable between a first position in which fluid flow through the second bypass flow path is restricted and fluid flow through the expansion device is allowed and a second position in which fluid flow through the second bypass flow path is allowed and fluid flow through the expansion device is restricted.
