The present embodiments relate to an HVAC system which is externally mounted on a vertical surface of an RV, truck or bus. The desire is to eliminate, or at least substantially reduce, a potential leakage path wherein water may sit on an upper surface of a vehicle and due to seal degradation over long periods of time, may find a pathway in through the roof of the vehicle and to an interior thereof. By positioning the HVAC on a vertical surface, gravity works to move water downward and away from the HVAC system rather than allowing it to stagnate in an area around potential apertures through the outer skin or outer surface of the vehicle.

An electrical adapter for electrically connecting a control unit of a heating device to an electric energy source and to an electrical signal source. The adapter may include a support, an electrical signal line, a first electrical supply line, a second electrical supply line, and a filter device. The signal line and the supply lines may be embedded in a plastic material of the support. Ends of the signal line may merge into a signal input connection and into a signal output connection. Ends of the supply lines may merge into a first and second electrical supply input connection and into a first and second electrical supply output connection. The filter device may be configured to filter an electric supply current conducted via the supply lines. The filter device may include a first and second electrical filter connection via which the filter device is electrically connected to the supply lines.

The present invention relates to a refrigerant manifold including a housing, a plurality of component mounting parts disposed on one surface of the housing and having component insertion holes formed in the same direction, the component insertion holes being configured such that components are inserted into component insertion holes, and a connection flow path configured to connect the component insertion holes of the plurality of component mounting parts, in which the component insertion holes connected by the connection flow path are disposed with a height difference H1, thereby reducing a size of a package.
