A movable air conditioner includes an air conditioner main body, an air conditioning unit installed in the air conditioner main body and configured to generate a cold air or a warm air, a moving unit configured to move the air conditioner main body, a control unit configured to control the air conditioning unit and the moving unit, and a human body recognition unit configured to recognize a person existing in a specific space. The control unit is configured to control the moving unit so that the air conditioner main body is moved toward the person recognized by the human body recognition unit so as to supply the cold air or the warm air from the air conditioning unit to the person recognized by the human body recognition unit.

A cooling system (20) includes a media exchanger (50), a cooling section (22), and a cooling circuit (120) for circulating a cooling fluid (130) between the media exchanger (50) and the cooling section (22). The media exchanger (50) receives outside air (38) and the cooling section (22) receives return air (32) from and interior space (34). When the cooling fluid (130) circulates into the cooling section (22) via the cooling circuit (120), the temperature of the return air (32) is reduced through indirect heat transfer between the cooling fluid (130) and the return air (32) to produce conditioned air (84). The conditioned air (84) is provided as supply air (46) into the interior space (34). When the cooling fluid circulates into the media exchanger via the cooling circuit, the temperature of the cooling fluid is reduced through direct heat transfer between the cooling fluid and the outside air.

An HVAC system utilizes one or more modular heat pump units installed within an outer wall or corner of a building, and one or more active registers. A central hub, which can be integrated into a modular HVAC unit, receives input from thermostats and sensors in the building and adjusts operation of the modular HVAC units and active registers to distribute conditioned air throughout the building. The system provides convenience and comfort of a traditional split HVAC system with significantly reduced installation and maintenance costs. The modular HVAC unit includes an interchangeable cartridge that contains the active components of a heat pump. Cartridges of different capacities can be installed as required, and are easily swapped out for maintenance, servicing, and replacement. A user can control the system using traditional-style thermostats and with a smart phone, tablet or computer. A cloud server provides backup services and remote access to the system.

Personalized air cleaning device (1) having a housing (2) which has at least one air intake region (3) for sucking air into the housing (2) and at least one air blow-out region (4) for blowing the air out of the housing (2), a cleaned blow-out air stream (32) being directed towards the body, and in particular against the face of a user, the housing (2) of the air cleaning device (1) being of approximately disc-shaped round or oval or polygonal design, and in that the air intake region (3) and the air outlet region (4) are arranged in the same plane (39) on the circumference of the housing (2).

The present invention relates to a disc-type air ecosystem box. The disc-type air ecosystem box includes a housing, and the housing is provided to accommodate a power module, a health processing module, a summer load module, a winter comfort module, a safety module, and an air supply module. The health processing module, the summer load module, the winter comfort module, and the safety module are located on the periphery of the power module, and the air supply module is located behind the power module. The present invention further discloses an air-conditioning method for said disc-type air ecosystem box.

A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. The PTAC includes an auxiliary fan configured for urging a flow of make-up air from the outdoor portion into the indoor portion through a vent aperture defined by a bulkhead. A vent door is positioned proximate the vent aperture and is operatively coupled with a reed switch assembly. A controller is configured for stopping the operation of the auxiliary fan when the reed switch assembly detects that the vent door is in the closed position.

The invention relates to the air environmental control technology field and discloses an environmental control unit including a shell, cooling device, a water pipe, a heating device, a control device, a sensor, a safety protection device, an air purification device and a humidifying device set in the shell. The invention combines the efficient circulation heating supply system with the air purification device. During the rapid heating of air, the cold-hot air convection is used to accelerate the air circulation purification and humidification treatment process. The sensor detects the real-time indoor air quality and adjusts the temperature, humidity and air quality by further control of the system according to the environmental parameters. The invention uses the air convection circulation to effectively improve the air purification and humidification efficiency with very high practical value. And it is of important positive significance for the development of water heating industry.

A low-microbe/low particulate commercial portable air conditioner includes a housing, the housing having an ambient air entry grill, a cold air discharge grate, a condenser air inlet gill and a warm air discharge grill disposed therein. The low-microbe/low particulate commercial portable air conditioner also includes a plurality of wheels, the plurality of wheels affixed to the housing and an evaporator positioned within the housing. In addition, the low-microbe/low particulate commercial portable air conditioner has an evaporator chamber positioned within the housing and abutting the evaporator, the evaporator chamber in fluid communication with the ambient air entry grill and the cold air discharge grate, the evaporator chamber coated with smooth surface insulation, a condenser positioned within the housing, wherein the condenser and condenser air stream are isolated from the evaporator chamber and evaporator air stream.

An air-conditioning apparatus, for treating air in enclosed environments, endowed with a constructive arrangement capable of absorbing vibrations of its inner components. The air-conditioning apparatus includes at least a cabinet, arranged to accommodate internal components of the apparatus, endowed with at least an outer face. The apparatus includes at least an absorber capable of absorbing vibrations from internal components of the apparatus. The absorber is disposed tangentially to at least an outer face of the cabinet.

A portable air conditioning and ambient fresh air supply system that provides ambient fresh or conditioned air to a user wearing a respirator. The apparatus comprises a cabinet having an upper chamber and a lower chamber. The lower chamber holds a refrigerant air conditioning system and the upper chamber holds a blower that supplies cooled air to the surroundings. The user is able to control the temperature of the conditioned air by means of a control panel and the air flow rate by a blower control switch.
