A modular cooling system for a vehicle including a base module having a refrigerant compressor, a high-pressure section having a direct or indirect condenser or gas cooler, and a low-pressure section having an evaporator and a chiller having chiller expansion elements connected upstream. The low-pressure section is connected via a heat pump expansion element to the high-pressure section. A first supplementary module has a heating branch having a heat pump heat exchanger, which is connectable via a first reheating branch having a valve element to the direct or indirect condenser or gas cooler, and a heat pump recirculation branch having a blockable valve element for connecting the direct or indirect condenser or gas cooler to the low-pressure section.

The invention relates to an air conditioning module, a modular air conditioning system, a transport vehicle and a method. The air conditioning module the air conditioning module (51) comprises an evaporator (65), a condenser (66) and a compressor (67) which are mounted to, onto or in the frame (60). The frame (60) further defines or bounds a first volume V1 that is arranged in air communication with the evaporator (65) and a second volume V2 that is arranged in air communication with the condenser (66). The second volume V2 is separated from the first volume VI, at least in the lateral direction T. The frame (60) is provided with one or more walls (71), (72), (73), (74) to at least partially define or bound the first volume V1 and the second volume V2. The first volumes V1 are aligned in the stacking direction S to form the continuous first air channel C1.

The mounting structure also includes a plurality of mounts disposed at the first surface, the plurality of mounts including a mount attached to the mounting plate via fasteners extending through the first plurality of apertures. The mounting structure also includes a mounting panel of a compressor unit of the auxiliary air conditioning system. The mounting panel includes a main portion having mounting apertures overlapping the plurality of mounts. Fasteners are disposed at the mounting apertures to attach the mounting panel to the mounting plate via the plurality of mounts.

An air-conditioner, adapted to be fitted to a roof/wall of a vehicle, comprises: an external unit containing a compressor and at least one heat exchanger element and having air channels respectively for supplying conditioned air and for receiving return air through an opening in a roof or wall of the vehicle, the opening being either of two types of different sizes; a frame to be installed in the opening and between the external unit and the roof/wall and having locating elements, on each of two opposite sides of the frame, configured to locate the frame in the opening and to locate the frame in the external unit, wherein the frame is to be installed with the first side facing the roof or wall for the first type of opening and is to be installed with the first side facing the external unit for the second type of opening.

A modular, roof-mounted air-conditioning system for a vehicle includes at least two similar air-conditioning modules for air-conditioning areas within the vehicle, wherein the air-conditioning modules are combined to form a functional assembly, and wherein the assembly can be installed on a roof of the vehicle.

An air treatment apparatus for an operator environment of an agricultural vehicle in which air to be filtered is drawn into an air filtration system, filtered and directed to an agricultural vehicle HVAC system. The air filtration system includes first and second filtration devices having respectively coarser and finer levels of filtration. Each filtration device is provided with a respective bypass permanently connected with an inlet end downstream of a valve mechanism that selects between the filtration devices, and an outlet end upstream of the valve mechanism and adjacent the respective filtration device. In use a portion of air flow downstream of the valve mechanism may be recirculated to purge the respective filtration device, and each bypass includes a respective non-return valve opposing transit of air from the outlet to the inlet ends.

A vehicle air-conditioning unit includes a seal compressing portion presses a sealing component against a partition wall that separates an interior and an exterior of a vehicle compartment. The seal compressing portion is positioned in the interior of the vehicle compartment and includes a tubing routing space through which inner tubing extends, and a drain space positioned below the tubing routing space to receive water drained from the tubing routing space. The drain space communicates with the exterior of the vehicle compartment via a through hole of the partition wall to discharge water from the drain space to the exterior of the vehicle compartment.
