The invention provides a cooling and heating integrated cabinet, a temperature controlling method and an unmanned vehicle. The cooling and heating integrated cabinet comprises a heating chamber and aPTC heating element, and the PTC heating element is connected with the heating chamber in a thermal conductivity mode. The cooling and heating integrated cabinet further comprises a compression heating system, and the compression heating system comprises a compressor, a condenser, a throttling device and an evaporator. The compressor, the condenser, the throttling device and the evaporator are connected in series successively, and the condenser is connected with the heating chamber in a thermal conductivity mode. First, the compression heating system is turned on to heat the heating chamber, the temperature of the heating chamber is raised at a lower power, and then the PTC heating element is switched to heat the heating chamber to reduce energy consumption. The unmanned vehicle adopting the cooling and heating integrated cabinet can heat or cool goods, the energy consumption for heating is low and the time of endurance is long.
