Auxiliary power unit for on board conditioning systems of power boats

摘要

A power unit for air conditioning systems installed on boats, including at least one compressor, of the mass produced type used in the automobile industry, connected to the circuit of the conditioning system, at least one mechanical pump for circulation of a heat exchange fluid along a circuit and one or more rotating electrical machines. Operation of the power unit is ensured during navigation by an internal combustion engine for marine propulsion, for example a four stroke engine of the type normally used for outboard marine propulsion, mass produced at low costs, while when the boat is in port it is ensured by an electric motor. The fan coils are also of the mass produced type used in the automobile industry.

主权项

1. A power boat equipped with an on board air conditioning system that includes an on board conditioning unit, comprising an auxiliary power unit for powering the on board conditioning unit without also powering marine propulsion drive of the power boat, the auxiliary power unit comprising at least one drive motor and means for driving the following components in rotation: at least one compressor connected to a circuit of the on board conditioning unit; at least one mechanical pump for circulating a heat exchange fluid along an open circuit; one or more rotating electrical machines, wherein said at least one drive motor is an internal combustion engine with a four stroke cycle; and a common fuel tank, and means for both fueling a main internal combustion engine of a main power unit that powers a drive for marine propulsion of the power boat and for fueling the internal combustion engine of the auxiliary power unit with fuel from the common fuel tank.
