(57) Abstract :
A first motor-actuated expansion valve and a second motor-actuated expansion valve which are connected in parallel with each other
in back-to-back connection are provided between an outdoor heat exchanger and an indoor heat exchanger. In the first motor-actuated
expansion valve, at the. time of non-operation and full closure, when the refrigerant pressure on the indoor heat exchanger side is
higher than the refrigerant pressure on the outdoor heat exchanger side by a predetermined value or more, the full closure is released
by receiving the refrigerant-pressure on the indoor heat exchanger side. In the second motor-actuated expansion valve, at the time of
non-operation and full closure, when the refrigerant pressure on the outdoor heat exchanger side is higher than the refrigerant pressure
on the indoor heat exchanger side by a predetermined value or more, the full closure is released by receiving the refrigerant pressure
on the outdoor heat exchanger side.
