Disclosed is a control method of a damper of a variable-air-volume air distributor and a control system thereof, mainly comprising a volume adjusting valve for the variable-air-volume air distributor, a valve actuator, a BP neural network-based main controller, a data collector and a user operation panel. The control method thereof is to use, mainly based on the collected room temperature and static pressure at the inlet of the air distributor, the BP neural network predictive model to establish a nonlinear model of temperature & static pressure and valve opening, perform training and optimization, and optimize the output valve opening to obtain and label an optimal value as the set value of the controller to control the action of the valve actuator, thereby realizing an automatic variable air volume.

A house is provided. The house includes a base and a roof. The roof is attached to the base. The base has sufficient buoyancy to enable the house to float on water.

A do-it-yourself-friendly self-contained marine air conditioning unit, marine air conditioning system, and method for installation is disclosed. The unit includes a seawater cooling circuit, a refrigerant circuit, and a blower assembly. The refrigerant circuit includes a reverse valve connecting a compressor, an evaporator, and a refrigerant tube thermally engaged with a titanium condenser coil. The seawater cooling circuit includes the titanium condenser coil. The titanium condenser coil has a titanium condenser coil outflow and a titanium condenser coil inflow. The blower assembly is mounted in communication with the evaporator, wherein the blower assembly may pull air through the evaporator. This blower is capable of achieving up to 270-degrees of rotation about a single axis. The system also includes a universal controller to allow for optimal integration with existing systems.

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 dehumidification system for a marine vessel includes a dehumidifier having a supply and return. The dehumidifier is supported in an interior space of the marine vessel, separated from the outside ambient environment. The supply provides dehumidifier to air through dedicated ducting to one or more locations throughout the vessel. The return includes dedicated ducting that draws air from a return grate located away from any doors on the vessel that are open directly to the outside ambient air. For example, the return grill is positioned in a space below deck. The dehumidification system includes a controller that is positioned near the return grate.

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.
