The invention relates to a convenient-to-replace air conditioning system for a new energy vehicle. The air conditioning system comprises a housing, a blower, an evaporator, an outlet pipe, an insertion mechanism, a sealing plate and a replacement chamber. The housing is provided with an inlet and an outlet. The replacement chamber is provided with a pushing-out mechanism. The shell is internally provided with a PLC, a magnet, a mesh plate, two filter elements and two placing mechanisms. The insertion mechanism comprises a baffle, a sliding plate, two sliding rails, two hinge units, a pluralityof insertion rods and a plurality of insertion rings. The pushing-out mechanism comprises a lifting assembly, a lifting plate, a vertical plate, a telescopic assembly and a push plate. According to the convenient-to-replace air conditioning system for the new energy vehicle, the filter elements that absorb too much can be conveniently pushed out of the housing by the pushing-out mechanism, the unused filter elements can be put into use by the placing mechanisms to ensure the respiratory health of passengers, moreover, the filter element can be conveniently inserted into the housing by the insertion mechanism for standby, thereby facilitating continuous air purification and improving the practicability of the equipment.
