摘要： PROBLEM TO BE SOLVED: To provide an air-conditioning circuit for a vehicle, having less temperature change of air to be fed to a vehicle room and assuring comfortableness of occupants. SOLUTION: The air-conditioning circuit comprises an externally controlled variable flow compressor 12 and an evaporator 20 through which an air flow F to be fed to the vehicle room H can pass. A comparison means 30 compares a target temperature at the rear stage of the evaporator with a limited target temperature at the rear stage of the evaporator, possibly causing the unbalance and unstability of a temperature in the evaporator, if higher. The control means 30 is responsive to the comparison to control the compressor 12 only or control heating means 21, 24 for heating at least a part of the air flow F fed from the evaporator 20.

摘要： The invention concerns an expansion member (40) for a motor vehicle air-conditioning unit (1) comprising a hollow tube (42) mobile in translation inside a ring (41), a peripheral orifice (45) arranged in said ring (41) and provided with a fluid inlet (45a) and outlet (45b), a member for closing (46) the peripheral orifice (45) adapted to shift from a first position wherein it closes the peripheral orifice (45) to a second position wherein it allows the cooling fluid through the peripheral orifice (45), and a compression spring (44) pressed against the ring (41) and a radial stop (43) fixed around the hollow tube (42), said spring (44) having an elastic return force (R) for maintaining the closure member (46) in its first closed position. In said expansion member (40), the closure member (46) is arranged on the side of the cooling fluid outlet (45b) and shifts from the first position to the second position when the pressure of the cooling fluid exerted directly thereon is greater than the elastic return force (R) of the spring (44).
