Abstract

PURPOSE: To preclude performance coefficient from dropping at the time of respectively driving even if calefactory efficiency may be more widely displayed than cooling efficiency by taking effect of dual intake system in a full eclosed type motor- driven compressor in an air conditioner equipped with cooling and calefactory functions.
CONSTITUTION: A full enclosed type motor-driven compressor 1 is constituted that drive of a motor-driven part 13 rotates a crankshaft 15, which recidprocates a piston 16, discharges gas drawn in through an intake valve 20 through a discharge valve 21, this discharged gas is circulated through for example a four-way valve 2, a heat exchanger 4 on the chamber internal side, capillary tubes 5, 6, a heat exchanger 3 on the chamber external side into the compressor 1 in order to make calefaction in the chamber. In this case, bypass circuits 8, 9, 26 conduct between the heat exchanger 4 on the chamber internal side and the capillary tube 5 for cooling and a cylinder chamber 7, a piping 26 is made in such a way that the opening can be provided at the joggled part 29 at the head part of the piston 16 in the position of the bottom dead point of the piping 26.
