A refrigerated air conditioning unit partitioned into an inside plenum and an outside plenum and having a single refrigeration loop, a single evaporator, and a recirculated air stream, the unit also having a dynamic intelligent air management system (DIAMS) internal to the unit that is cooperatively configured and operable to continuously introduce preconditioned fresh air directly into the recirculated air stream whenever the unit is operating and to exercise control over a mixed air flow discharged from the unit into an identified space to achieve a desired air temperature and humidity within the identified space.

The window air conditioning and heating unit controls the environmental conditions within a room of a building. The window air conditioning and heating unit mounts in a window of the room. The window air conditioning and heating unit measures and monitors the temperature of and the humidity in the air in the room. The window air conditioning and heating unit comprises an environmental control structure, a control circuit, and a housing. The environmental control structure provides the heat and mass transfer capabilities required to control the temperature and humidity within the room. The control circuit controls and powers the operation of the environmental control structure. The environmental control structure and the control circuit are contained in the housing.

A method for manufacturing a heat transfer module for a dehumidifier may include forming a U shaped heat pipe having one straight portion acting as a heat-dissipation pipe, the other straight portion acting as a heat-absorbing pipe, and a connection pipe having a curved shape and connecting the two straight portions; inserting a heat-emitting fin and a heat-absorbing fin into the heat-dissipation pipe and the heat-absorbing pipe, respectively; expanding the heat-dissipation pipe and the heat-absorbing pipe such that the heat-emitting fin and the heat-absorbing fin are fixed to the heat-dissipation pipe and the heat-absorbing pipe, respectively; sealing one end of the heat pipe; injecting working fluid into the heat pipe through the other end of the heat pipe; and sealing the other end of the heat pipe containing therein the working fluid.

A humidification and air cleaning apparatus is provided, in which a first sweep angle and a second sweep angle are formed at diffuser blades, and an included angle is formed between the first sweep angle and the second sweep angle, such that a phase difference is formed in air passing through the diffuser blades, and thus, air flow noise may be reduced.

A humidification and air cleaning apparatus is provided, in which a wave having a predetermined cycle is formed on a plurality of blades of a blower fan, such that operating noise caused by a flow of discharged air may be minimized, and a wave is formed at a trailing edge, such that a phase difference may be formed for air to be separated, and air flow noise of the discharged air may be reduced.

A heating and cooling apparatus is disclosed that combines a PTC heating element with a fan, and a combination of a cooling device aided by a thermoelectric cooling device to provide heating, passive air conditioning, and air circulation. The heating and cooling apparatus can include a condensation trap, a collection container, and an ozone generator for collecting and purifying the condensate. In addition, this apparatus provides the additional function of serving as an air purification system operating either in combination with the heating/cooling functions or as an independent air purifier.
