There is described a ventilation system for a boat. The windshield body comprises an air scoop in a bottom portion of the windshield body, facing a forward direction of the boat for air entry, the air scoop having an entry which is substantially horizontal and the air scoop extending upwardly within the windshield body to form a conduit having an upward component. The conduit end opens toward an inside of the boat, at a location higher than the entry of the air scoop. A hingeable vent can be installed on the opening inside the boat to be open or closed. The vent may also be sued with a direct opening with the outside. In this case, flaps can be installed in the opening. The flaps can be hingeable about their own respective hinge axis, and move together using a solid link. The flaps may be used without the vent.

A marine air conditioning unit, according to various embodiments, can include a base plate having one or more mounting holes. A main unit is supported on the base plate comprising an evaporator, a compressor, a compressor driver, a condenser, an electronic expansion valve, a blower, an electrical pressure sensor and a condensation pan operatively coupled together. The compressor can be a variable speed inverter brushless direct current (BLDC) compressor. The electronic expansion valve can be located in a refrigerant line connecting the condenser to the evaporator. A controller can constantly receive and, using an algorithm, analyze sensor information from multiple sensors positioned within the main unit. Based on the sensor information, the controller can transmit a control signal to various components and further adjust the electronic expansion valve to control the precise amount of refrigerant to pass to the evaporator.

A swivel gyro-mount system for a self-contained air conditioning system, disclosing a unit having a main body with an evaporator having an evaporator cover with an aperture bordered on a side opposite of the evaporator by a plurality of frustum-spherical wall sections, thereby creating a boundary. A frustum-spherical gyro-swivel ring is positioned within the boundary of the frustum-spherical wall sections. A fitment ring is removably affixed to a protruding lip of the frustum-spherical gyro-swivel ring. The frustum-spherical wall sections movably contain the frustum-spherical gyro-swivel ring in a tight periphery, thereby allowing the frustum-spherical gyro-swivel ring to adjust in orientation, whereby the adjustment in orientation influences a direction of airflow in a conical range of orientations to a blower, whereby said blower may expel air in a plurality of selectable directions in a range of angulation resembling a dual conical shape.

An air vent for a vehicle interior, the air vent including a master lamella and plural slave lamellas that are respectively pivotable about an axis, wherein the plural slave lamellas follow an opening movement of the master lamella and are arrangeable at different angles relative to the master lamella in order to generate a diffuse air flow; an open portion which is defined by a plurality of lamellas including the master lamella and the plural slave lamellas with a respective flow out gap arranged between each of the lamellas so that air moves through the respective flow out gap into the vehicle interior; and at least one actuation element that is configured to control an orientation of the lamellas, wherein any one of the lamellas is selectable as the master lamella wherein an opening movement of the plural slave lamellas follows an opening movement of the master lamella.

A vessel having an air circulation system allowing better exploitation of the spaces inside the vessel is provided. The flanks of the hull of the vessel are used for accommodating at least part of the components of the air circulation system to free up useful space on decks, in order to use it for other purposes. Porthole frames are used for making air ports for the ventilation and air conditioning system to simplify the design of the system and not to deteriorate the outer appearance of the hull.
