The present disclosure relates to an air port component and an air conditioner, wherein the air port component includes a first plate body and a second plate body, wherein two longitudinal ends of the first plate body and the second plate body are elastically connected respectively. When the working environment temperature difference is relatively large, even if the difference between the linear expansion coefficients of materials used by the two plate bodies is relatively large, extension or shrinkage generated between the plate bodies due to temperature changes is be compensated by the elastic connection so as to reduce the degree of plastic deformation of the plate bodies due to temperature changes after being used for a period of time, thereby improving the reliability of the operation of the air port component, preventing blockage during the operation, as well as ensuring that the airflow of the air outlet meets the design requirements to prevent condensation due to local overcooling.

A thermally broken panel assembly includes a first panel member, a second panel member, a first insulating member, and a second insulating member. The first panel member includes a first base member, and a first wall extending outwardly from an outer edge of the first base member. The second panel member includes a second base member, a second wall extending outwardly from an outer edge of the second base member, and a second flange extending from an upper end of the second wall. The first insulating member is disposed between the first wall and the second flange. The second insulating member is disposed between the first base member and the second base member. A gap is disposed between an edge of the first wall of the first panel member and an edge of the second wall of the second panel member.

A display assembly includes a display box including a base plate having a display portion and a key via hole, an electric control board provided in the display box, and a flexible isolation pad provided in the display box. The flexible isolation pad is located between the base plate and the electric control board, and is configured to isolate the base plate from the electric control board. The display assembly further includes a control key movably provided in the key via hole. The control key is configured to abut against the flexible isolation pad, and to interact with the electric control board through the flexible isolation pad.

A smart air conditioner for reduction in fine dust and harmful gas includes: an eternal chamber including a first side coupled to communicate with an interior and a second side communicating with an exterior; an internal chamber disposed to pass through an inside of the external chamber and including a first side coupled to communicate with an interior and a second side communicating with an exterior; an external chamber damper installed in the external chamber and controlling air flow; and an internal chamber damper installed in the internal chamber and controlling air flow.

A wine cellar includes a storage room for storing food, a cooling device for supplying cooled air to the storage room, a heating device for supplying heated air to the storage room and a fan for circulating outside air of the wine cellar and inside air of the storage room. A temperature sensor senses the temperature in the storage room. A processor determines an operation mode of the wine cellar on the basis of the sensed temperature of the storage room and a set temperature for the storage room, and selectively controls the cooling device or the heating device on the basis of the determined operation mode. When the determined operation mode is a heating mode, the processor controls the fan to allow the outside air to flow into the storage room, and controls the heating device to start supplying the heated air during the operation of the fan.

A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.

The presently disclosed subject matter is directed to a vent register for use with an HVAC system. The register is defined by a housing comprising top and bottom plates that are permanently joined to create an interior compartment. The interior compartment imparts an insulative quality to the register by providing resistance to an increase or decrease in temperature, such as when cooled air is flowing through the system. The interior compartment can be hollow and filled with air, foam, or any insulative material. In use, the register prevents or reduces the incidence of condensation forming on the face of the register during use.

A control system includes a cleaner dispensing system and a computing device. The cleaner dispensing system includes a cleaner dispensing apparatus having a dispenser device configured to operate to dispense a cleaning composition. The cleaner dispensing system includes a cartridge configured to detachably couple with the cleaner dispensing apparatus to provide a cleaning composition held in a cartridge reservoir to the dispenser device. The cartridge includes a cartridge indicator configured to indicate a particular cartridge identifier code associated with the cartridge. The computing device is configured to detect the particular cartridge identifier code based on obtaining cartridge information from the cartridge indicator and to transmit an apparatus enable command signal to the cleaner dispensing apparatus, to cause the cleaner dispensing apparatus to selectively enable operation of at least the dispenser device, in response to a determination that the particular cartridge identifier code matches an authentic cartridge identifier code.

An HVAC system includes an evaporator. The evaporator includes a sensor configured to measure a property value (i.e., a saturated suction temperature or a saturated suction pressure) associated with saturated refrigerant flowing through the evaporator. The system includes a variable-speed compressor configured to receive the refrigerant and compress the received refrigerant. The system includes a controller communicatively coupled to the sensor and the variable-speed compressor. The controller monitors the property value measured by the sensor and detects a system fault, based on the monitored property value. In response to detecting the system fault, the controller operates the compressor in a freeze-prevention mode, which is configured to maintain the property value above a setpoint value by adjusting a speed of the variable-speed compressor.

A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.
