Some embodiments of the present disclosure provide an air conditioning system. The air conditioning system includes: a housing, having an indoor air supply port; a first heat exchanger, disposed in the housing, an air outlet of the first heat exchanger being communicated with the indoor air supply port; a first air supply mechanism, disposed in the housing, an air outlet of the first air supply mechanism being provided correspondingly to an air inlet of the first heat exchanger; and a plurality of replaceable assemblies, wherein each of the plurality of replaceable assemblies can be assembled in the housing, and the housing is selectively cooperated with one or more of the plurality of replaceable assemblies.

The invention relates to an exchanger element (1) for use on board a vehicle, in particular for a passenger compartment and/or the engine bay of a vehicle. The exchanger element has an exhaust air flow path (2) and a feed air flow path (3), wherein the exhaust air flow path and the feed air flow path are separated from one another by partition sections that have heat-transmitting wall regions. The exhaust air flow path (2) forms a fluid connection from the interior of the vehicle to the outer surroundings of the vehicle. The feed air flow path (3) forms a fluid connection from the outer surroundings of the vehicle to a location on board the vehicle. According to the invention, the exchanger element (1) is embedded in a package (4), the outer surface area shape of which matches the inner dimensions of an installation space on board the vehicle for the installation of the exchanger element (1).

A heating, ventilation, and/or air conditioning (HVAC) unit includes a heater housing having a first side wall, a second side wall opposing the first side wall, and a ceiling extending between the first side wall and second side wall. The HVAC unit also includes a first mounting rail disposed across the first side wall at a first distance from the ceiling, and a second mounting rail disposed across the second side wall at a second distance from the ceiling. The first distance is greater than the second distance. The HVAC unit also includes a heating element assembly coupled to the first and second mounting rails and having a planar heating interface extending from the first mounting rail to the second mounting rail.

A refrigerated air conditioning unit partitioned into an inside plenum and an outside plenum and having a single refrigeration loop, a single evaporator, and a recirculated air stream, the unit also having a dynamic intelligent air management system (DIAMS) internal to the unit that is cooperatively configured and operable to continuously introduce preconditioned fresh air directly into the recirculated air stream whenever the unit is operating and to exercise control over a mixed air flow discharged from the unit into an identified space to achieve a desired air temperature and humidity within the identified space.
