    摘要： A heat pump type air conditioning system (A) for an automotive vehicle. The heat type air conditioning system (A) comprises a first unit (10) including a heater core (11) through which an engine coolant of an engine flows, and a first heat exchanger (12) which forms part of a refrigeration cycle including a compressor (1) and a first condenser (3), in which a refrigerant circulates in the refrigeration cycle. A second unit (20) is provided including a second condenser (21) and a second heat exchanger (22) which are fluidly connected in parallel with the first heat exchanger (12). A valve (V2) is fluidly connected in series with the second condenser (21) and disposed such that a part of the refrigerant is introduced through the valve into the second condenser (21) and the second heat exchanger (22). A sub-heat exchanger (30) is disposed outside the first and second units and fluidly connected in series with the second heat exchanger (22), in which the refrigerant flowing from the second heat exchanger (22) is introduced into the sub-heat exchanger to be heated by a part of the engine coolant, the refrigerant discharged from the sub-heat exchanger being returned to the compressor. An electromagnetic clutch (40) is provided such that the compressor (1) is drivably connectable with the engine therethrough. The electromagnetic clutch is engaged to establish a driving connection between the compressor so as to operate the compressor and disengaged to cut the driving connection so as to make the compressor inoperative. A control device (C) is operatively connected to the electromagnetic clutch (40) for controlling the electromagnetic clutch to be disengageable in accordance with a temperature within the air conditioning system (A).

    摘要： A heat pump type air conditioning system (A) for air-conditioning a passenger compartment of an automotive vehicle. The air conditioning system comprises first and second units (10, 20). The first unit includes a heater core (12) and a first evaporator (13) while the second unit includes a second condenser (22) and a second evaporator (23). A compressor (2) and a first condenser (3) are disposed outside the first and second units which constitute a refrigeration cycle including the first evaporator (13). A circuit change-over valve (4) is provided to cause flow of the refrigerant discharged from the compressor (2) to be changed over between a refrigeration operation refrigerant circuit including the first condenser and a heating operation refrigerant circuit including a bypass passage for allowing the refrigerant to flow bypassing the first condenser. A third evaporator (30) is disposed outside the first and second units (10, 20). A flow control valve (31) is provided to control a flow amount of the engine coolant circulating through the third evaporator (30) in accordance with a thermal load condition of the vehicle under control of an opening degree of the flow control valve, during the heating operation of the air conditioning system. The flow control valve (31) is set to take its fully closed state to prevent the engine coolant from circulating through the third evaporator (30) when a discharge pressure of the compressor (2) rises to a level not lower a first set value which is lower than a standard value to stop an operation of the compressor, and to take its fully opened state to allow the engine coolant to circulate through the third evaporator (30) when the discharge pressure of the compressor (2) lowers to a level not higher than a second set value which is lower than the first set value.

    摘要： Described is an apparatus for air conditioning a passenger compartment of an automotive vehicle which achieves a quick warming-up of the passenger compartment. In the air conditioning apparatus, in addition to a coolant of a vehicular engine which is utilized as a heat source of a heater core, a highly compressed refrigerant discharged from a compressor can be utilized as a heat source of a sub condenser which is disposed in an air passage of the air conditioning apparatus, during the inside air warming up in the passenger compartment. During the warming up operation, the refrigerant discharged from the compressor is circulated through a bypass line bypassing a condenser disposed at a front part of an engine compartment and through the sub condenser and an evaporator.

    摘要： A centrifugal multiblade fan comprises a plurality of curved blades which are circularly arranged about a common rotation axis at evenly spaced intervals defining a curved air flow passage between every neighboring blades. Each curved blade has concave front and convex rear surfaces which extend longitudinally in parallel with the rotation axis. A lower annular end plate is provided for putting thereon lower ends of the circularly arranged blades. A radially outside part of each curved blade has a radius of curvature which is greater than that of a radially inside part of the blade. A slit extends longitudinally parallel with the rotation axis at a radially inside portion of each blade.
