An HVAC system is provided. Embodiments of the present disclosure generally relate to heat exchangers having tubing with a reduced diameter compared to traditional systems. In one embodiment, a ducted HVAC system comprises an outdoor heat exchanger with tubing that has an outer diameter of eight millimeters (8 mm) or less and an indoor heat exchanger with tubing that has an outer diameter of nine millimeters (9 mm) or less. Additional systems, devices, and methods are also disclosed.

The invention relates to air cleaning and enrichment systems, namely, to systems for providing a user with a healthy air, and it may be used in living, training, medical and working rooms, interiors and cabins of vehicles in order to provide household, medical and other people needs in the air that is cleaned from harmful impurities and chemically healthy.

The system In.AirBox for providing a user with a healthy air is capable of creating the airflow and comprises a room with at least one means for arranging the user, an air delivery duct, a control device, at least one container comprising the air that is collected in a forest area or in mountains, or over a sea or a seaside, or cleaned from harmful impurities, or comprising added healthy impurities, an air output duct that is coupled to the at least one container comprising the air and that is capable of supplying the air from the at least one container into the room. The air delivery duct is configured with a filter and is capable of supplying the air from the environment into the room that is capable of being closed and equipped with at least one measurement device that is capable of measuring the air pressure and/or temperature, and/or moisture, and/or a number of impurities therein, and coupled to the control device, while the control device is capable of regulating the airflow rate supplied from the air output and delivery ducts depending on parameters of the at least one measurement device.

A technical effect lies in increase of the efficiency, providing safety for the user's health, flexibility, simplicity of use, simplification of the structure, cost-cutting of the air cleaning and enrichment process.

A blow-dry enclosure has an inflatable bag made of rugged material, with on the front an opening to receive air from an air mover, and a vent or a vent carrier that can receive a vent. The inflatable bag may be in the shape of a block. The material may be coated with an impermeable layer, and it may be lightweight and machine-washable. The blow-dry enclosure may have two or more inflatable towers on the top, and an opening on the back to receive air. The vent may be removable, replaceable, and adjustable. The blow-dry enclosure may have a hose on the front opening to connect it to the air mover. It may further have connector flaps to connect it to other blow-dry enclosures, straps to allow it to curve forward or backward, or shorten it, and/or anchor tabs to tie it to the ground.

Systems and methods for controlling operation of one or more fans of an air handling system having one or more filters or filter banks. A current air volume at an inlet side of the fan(s) is determined. In some embodiments, the inlet side air volume is determined via sensed pressure at the inlet side (e.g., pressure transducer open to a flow station at the inlet side). A controller operates to control or regulate a speed of the fan in a manner that maintains a constant air volume through the air handling system, for example based upon a comparison of the current air volume at the fan with a target air volume.

An air cleaner includes a blower, a circulator disposed over the blower, and a mover coupled to the circulator and configured to change an arrangement of the circulator. The circulator includes a lower cover, an upper cover disposed over the lower cover, a blower fan rotatably disposed between the lower cover and the upper cover, a motor disposed on an upper side of the lower cover and rotating the blower fan, an inner cover disposed over the lower cover and receiving a lower portion of the blower fan, and a bell mouth protruding upwardly from an inner circumferential end of an inner plate of the inner cover and spaced apart outwardly from a circumferential surface of a suction guider of the blower fan, so as to guide air, drawn in through an inlet of the lower cover, toward an inlet of the blower fan.
