Theme : A cooling cycle for a twin air conditioning system which provide with a structure that eliminates the disadvantage arising from providing expansion devices with different control systems on each evaporator, thereby holding down manufacturing costs and eliminating or simplifying the work of tuning the system. Means of Resolution : A structure having compressor 2 which raises the pressure of the coolant to beyond the supercritical pressure, radiator 3 which cools the coolant which has been pressurized by compressor 2, expansion device 4 which reduces the pressure of the coolant flowing from the radiator so that the pressure on the outlet side of the radiator is held to a prescribed pressure determined by the temperature of the coolant on the outlet side of the radiator, first and second evaporators 5, 6 which evaporate coolant whose pressure has been reduced in expansion device 4, and a flow regulator means (flow regulator valve 7) which regulates the quantity of coolant supplied to evaporators 5, 6 respectively. |
