Embodiment Construction

[0028] figure 1 A schematic diagram of an air-conditioning circuit of a mobile air-conditioning system 2 , in particular an air-conditioning system of a vehicle, is shown. Air conditioning systems consist of closed-circuit plumbing between system components in which coolant circulates. The coolant is compressed by the compressor 17 and flows to the condenser 18 in which the coolant is liquefied. After leaving the condenser, the coolant is in liquid state and exhibits a temperature of 30°C to 50°C (degrees Celsius) at a pressure of 7 bar to 15 bar (atmospheric pressure). The liquefied coolant is now supplied to the first flow channel 5 of the internal heat exchanger 1 according to the invention, in which the coolant leaving the condenser 18 gives up heat to the evaporator 20 via the second Gaseous coolant in flow channel 6. The liquid coolant then flows into the expansion valve 19 where the coolant pressure is reduced. The coolant absorbs heat in the evaporator 20, where th...
