The air conditioning installation which, in addition to the actual air conditioning operation, also makes possible an (additional) heating operation by means of acting upon the evaporator with compressed, hot coolant gas, is suitable for the implementation of a further energy-saving heating operation, if the evaporator is a coolant/cooling water heat exchanger and the treatment of the air flowing into the vehicle interior takes place in a conventional air/cooling water heat exchanger. During air conditioning and (additional) heating operation, the latter is connected to the coolant/cooling water heat exchanger in a separate cooling water circuit which is insulated from the actual cooling water circuit, and, when the temperature of the cooling water in the actual cooling water circuit is sufficient, is connected to this circuit. At the same time, the coolant/cooling water heat exchanger is then disconnected. |
