This application relates to a humidifying device, including a shell, an air duct and an air blowing apparatus disposed in the shell, wherein a mist outlet channel, an atomizing cavity and a heating cavity communicated with the mist outlet channel are disposed in the shell; the air duct includes a first air duct communicated with the atomizing cavity and a second air duct communicated with the heating cavity; the air blowing apparatus is provided with an air outlet member, and the air outlet member is aligned with the first air duct and the second air duct, and is configured to supply a first air flow to the first air duct and supply a second air flow to the second air duct. When the humidifying device operates, the first air flow forms an atomized air flow and the second air flow forms a heated air flow then are mixed.

A temperature control (“TC”) unit and associated method for providing simultaneous independent temperature control of conditioned air to first and second rooms. The TC unit includes a cabinet. The cabinet may be divided into first and second compartments, the first compartment being adapted to receive and exhaust air from and to, respectively, the first room, and the second compartment being adapted to receive and exhaust air from and to, respectively, the second room. Sound dampening insulation may be positioned between the first and second compartments. First and second evaporators may be positioned within the cabinet so that: air from the first room passes through the first evaporator before exhausting back to the first room; and air from the second room passes through the second evaporator before exhausting back to the second room. The TC unit may be or include a vertical terminal air conditioning (“VTAC”) unit.

This patent application covers design and modular manufacturing techniques for an economical air handler and exhaust fan product line that delivers better energy performance, acoustical performance, space utilization, and operational efficiency than is available in today's marketplace. An axial fan is positioned within airflow guides designed to minimize turbulence to reduce acoustics and energy consumption. The specific arrangement of air filters, heating and cooling coils, airflow guides, sound attenuating surfaces, fan modules, control panels, backdraft dampers and isolation dampers enables the stacking of modular units to meet air handler capacity requirements with inherent redundancy. In some configurations, the air handler described provides complete redundancy for a no-shutdown system that will reduce HVAC energy requirements to a lower level and provide a greater operating range than is available in today's market.

A preconditioned air unit for supplying preconditioned air to an aircraft parked on the ground, the preconditioned air unit comprising a housing accommodating a flow duct with an air inlet for ambient air and an air outlet for connection to the parked aircraft, a blower connected with the flow duct for generation of an air flow from the air inlet toward the air outlet, at least one refrigeration system, each of which includes at least one compressor, at least one condenser, at least one expansion valve, and at least one evaporator connected in a flow circuit containing a refrigerant, and wherein the at least one evaporator interacts with the air flow in the flow duct, and at least one variable frequency driver for power supply of at least one of the at least one compressor of the at least one refrigeration system.

A system includes a high side heat exchanger, a flash tank, a compressor, and eight metal beams. Each of the metal beams extend in a linearly vertical direction. The eight metal beams define ten planar boundaries. The first, second, third, and fourth planar boundaries define a first space. The first, fifth, sixth, and seventh planar boundaries define a second space. The fifth, eighth, ninth, and tenth planar boundaries define a third space. The high side heat exchanger is contained entirely within the third space. The flash tank is contained entirely within the first space. The compressor is contained entirely within the second space.

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.

The intelligent splicing air purifier is consist of several single units. Each unit is equipped with at least one side with the first air outlet, external power interface and switch; at least one other side with internal power interface along with a control panel inside the unit. Two separated air purifiers can be connected via a conductive connector that connect the internal power interface of both units. The control box is able to connect via the wireless transmission module with the control panel of the units. It can control the operation status of the air purifier unit in a wireless way. The intelligent splicing air purifier is convenience to use because through the connection between cell phone terminal and the control box of units, customer is able to control one or more air purifier unit simultaneously.

The present invention relates to a modular bulkhead system that provides structural support for a fan array system. Although this system is very useful for retrofit installation of new fan array and bulkhead systems within already existing air handling units, it also provides several advantages for new air handling units when installed during their original equipment manufacturer. The modular bulkhead system allows for a modular bulkhead wall to be customized and installed within a cabinet of an air handling unit. The modular bulkhead wall cleverly provides one or more intermediate bulkhead stiffening elements that enable the modular bulkhead wall to adequate support the fan array system and resist the differential pressures that result on opposing sides of the bulkhead wall during operation of the air handling unit.

An air handling unit (AHU) for a heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a housing and a combustion heater disposed within the housing. The housing includes a combustion section with a first channel and a second channel. The combustion heater includes heat exchanger tubes and a tube support that supports heat exchanger tubes within the combustion section. The tube support slidably disposed in the first channel and the second channel. The combustion heater configured to be slidably removable from the AHU. An AHU for an HVACR system includes a housing with a fan section and a fan assembly disposed within the housing. The fan assembly including a pair of grooves slidably disposed on a pair of rails of the housing. The fan assembly configured to be both slidably removable from the AHU and liftably removable from the AHU.

An air cleaner may include a housing including a first housing having a discharge outlet through which air is discharged outside of the air cleaner, and a second housing including a suction inlet through which air is suctioned from outside of the air cleaner, and a filter assembly accommodated inside of the housing and that filters air.
