摘要： PROBLEM TO BE SOLVED: To prevent the wearing of a desiccant both for the cooling and heating operations by providing a drier with a desiccant sealed therein between an outdoor expansion device and a receiver to reduce the amount of moisture in a refrigerating cycle. SOLUTION: In the cooling operation, a gas refrigerant delivered from an inverter variable capacitance compressor 1 or a constant speed compressor 2 is condensed by an outdoor heat exchanger 6 and the refrigerant as condensed liquid is turned to a liquid refrigerant with the dryness thereof being almost zero by a supercooling heat exchanger 9 to be dewatered passing through a drier 10 without being choked with an aid of an outdoor expanding device 8. In the cooling operation, as the temperature of the outside air is higher than that during the heating operation, the temperature on the perimeter of a container of a receiver 12 is also high to reduce the condensation of the gas refrigerant in the receiver container. This allows passing of a refrigerant almost in a single phase of liquid that lets little bubbles be infiltrated thereinto even when the drier 10 is located on the inlet side of the receiver during the cooling operation thereby completely preventing the wearing of a desiccant.

摘要： PROBLEM TO BE SOLVED: To prevent sound from being generated and further prevent a reaching distance of blown air from being shortened by a method wherein there is provided a plate for closing either a hole or a slit arranged at an air directing plate installed at an air outlet of an indoor device so as to cause the supply air to be flowed at a side opposite to such a side as one where the supply air is directly struck against it. SOLUTION: A shielding plate 10 arranged at an air directing plate 8 is moved to close a slit 9, thereby supply air is prevented from being passed through the slit 9, resulting in that sound of air when the air passes through the slit 9 is prevented from being generated and further a problem that an amount of air of the supply air of which air direction is controlled by the air directing plate is reduced and an air speed is also reduced to cause a reaching distance of the air to be shortened is avoided. The shielding plate 10 is constructed such that it enables either the hole or the slit arranged in the air directing plate 8 for use in flowing the supply air to a side opposite to that where the supply air directly strikes to be opened or closed irrespective of automatic or manual operation of it. It may also be applicable that the slit 9 is closed under a rotational motion of the shielding plate 10 around the longitudinal direction of the short distance direction or the normal line direction of the air directing plate 8.
