摘要：the invention relates to a device and a method for heating and cooling anutzraumes of an brennkraftmaschine (1) driven vehicle.the device has a

k\ältemittelkreislauf with a compressor (2), a umgebungsw\ärmetauscher (10),at least one expansionseinrichtung (8), a innenraumw\ärmetauscher (6) and theexhaust of the brennkraftmaschine (1) heated abgasw\ärmetauscher (13).this is arefrigerant in heating operation by the compressor (2) and under heat by the compressor(2) downstream innenraumw\ärmetauscher (6).the compressor (2), theinnenraumw\ärmetauscher (6), the expansionseinrichtung (8), the

umgebungsw\ärmetauscher (10) and the abgasw\ärmetauscher are seriallyarranged so that the refrigerant in the expansionseinrichtung (8) at a temperature belowa ansaugtemperatur of k\ältemitt els in the compressor (2) is expanding.in theumgebungsw\ärmetauscher (10) with warmer air is in the angasw\ärmetauscher(13) with the exhaust from the brennkraftmaschine warms up and the compressor (2) iscompressed.in cooling operation, the compressor (2), the

umgebungsw\ärmetauscher (10), the expansionseinrichtung (8) and the

innenraumw\ärmetauscher (6) arranged in series, and the refrigerant in the

umgebungsw\ärmetauscher (10) with colder air to and in the expansionseinrichtung(8) a uf a temperature below a nutzraumlufttemperatur expands.and the nutzraumluft inthe innenraumw\ärmetauscher (6) with the colder refrigerant is charged.
