[0004] The statements in this section are provided only as background information in relation to this disclosure and do not constitute prior art.

[0005] Air conditioners are typically installed on the roof of a bus.

[0006] An air conditioner is a device that condenses high-temperature, high-pressure refrigerant gas from a compressor into a liquid by exchanging heat with the outside air, and the outside of the air conditioner is covered by a casing.

[0007] Figure 1 This illustrates an air conditioning housing for a passenger car in the prior art.

[0008] In the prior art, the air conditioner housing is formed as a single piece. A shroud 2, which is embedded in the exhaust port of the air conditioner, is attached to the central part of the housing. A pair of covers 3 and 4 are attached to the housing 1 and are provided on the left and right sides of the upper side of the housing 1, and a shroud cover 5 is attached to the upper part of the shroud 2.

[0009] As mentioned above, in the prior art, the housing 1 and the cover 2 of the air conditioner casing are manufactured as a single piece. We have found that this integral manufacturing leads to an increase in product weight and manufacturing costs.

[0010] Furthermore, since the housing 1 or the shield 2 is manufactured as a single piece, even if only part of the housing 1 or the shield 2 is damaged, the entire housing 1 and shield 2 need to be replaced, thus reducing maintainability. Summary of the Invention

[0011] This disclosure provides an air conditioning housing for a bus, wherein the housing for an air conditioner installed on the bus is modularized into individual components, thereby reducing the weight of the vehicle and lowering manufacturing costs, and the modular components can be shared, thereby improving maintainability.

[0012] One form of the present disclosure provides a modular housing of a bus rooftop air conditioner, the housing including: a pair of first and second bases installed to be spaced apart from each other and opposite to each other; and one or more shrouds coupled into a space between the first and second bases spaced apart from each other, wherein the number of shrouds to be connected and installed in the housing can vary according to a capacity of the air conditioner.

[0013] The modular housing of a bus rooftop air conditioner according to the present disclosure as described above has an advantage in that the housing for the air conditioner installed on a bus can be modularized into separate components, thereby reducing the weight of the vehicle.

[0014] An obtained advantageous effect is that manufacturing costs can be reduced by using the modular components, and commonality of the respective modular components can improve maintainability.
