ABSTRACT:
An air-conditioning installation for motor vehicles, especially for passenger motor vehicles, in which the cooling medium circulation is adapted to be switched from cooling to heating by a flow direction reversal. For purposes of heating, a by-pass line which by-passes the expansion valve effective during cooling and which contains a pressure-holding valve, terminates in a multi-channel partial area of the cooling-condenser effective as heating-evaporator so that a high heat output is produced from the compression heat and from the additional heat pump effect.
