This utility model relates to the field of garment processing technology, specifically providing a garment processing device aimed at solving the problem of short service life of the electric heating module in existing garment processing equipment. To this end, the garment processing device of this utility model includes a drum and a drying device. The drying device includes a circulating air duct and an electric heating module. The electric heating module includes multiple strip-shaped heating elements spaced apart along a first direction, extending along a second direction perpendicular to the first direction, and the multiple strip-shaped heating elements are arranged in parallel. By setting multiple parallel strip-shaped heating elements, when one strip-shaped heating element fails, the remaining strip-shaped heating elements can continue to work, extending the service life of the electric heating module. Using multiple parallel strip-shaped heating elements increases the overall heating power of the electric heating module, which is beneficial for improving drying efficiency and achieving uniform heating, avoiding problems such as localized overheating or uneven heating.

This invention relates to the field of data center air supply technology and discloses a data center zoned air supply device based on differential pressure feedback. The device includes a precision air conditioner installed in the data center. The cold air outlet of the precision air conditioner is connected to an air duct. Several air supply mechanisms are installed below the air duct. Each air supply mechanism supplies air to the server racks in its designated area for cooling. Each air supply area is equipped with a set of pressure sensors, located at the cold aisle inlet and hot aisle outlet of the server rack, to monitor the air pressure in the cold and hot aisles. Louvered air vents are installed at the ends of each air supply mechanism, corresponding to each air supply area. The airflow from the louvered air vents is adjusted based on the air pressure difference monitored by each set of pressure sensors within the cold and hot aisles of the server rack. This dynamic adjustment of airflow according to the actual heat load of the server rack avoids uneven cooling caused by uniform air supply, improves cooling efficiency, and reduces energy consumption.

The application provides an air conditioner and a control method thereof. The air conditioner comprises a heat exchange part, a circulating part, a processor and a memory, and the circulating part comprises at least a first air supply mode. When the circulating part executes the first air supply mode, the running speed of the heat exchange part is obtained. The indoor air outlet speed of the circulating part is adjusted according to the running speed of the heat exchange part, so that the indoor air outlet speed of the circulating part and the running speed of the heat exchange part are matched, the indoor air entering the heat exchange part through the circulating part can be fully heat exchanged, and the heat exchange efficiency is improved. During the working process, the indoor air entering the circulating part reduces the air density around the circulating part, the lower cold air flows to the upper part of the room, the vertical temperature difference is reduced, the air uniformity of the whole room is greatly improved, the phenomenon of "hot upper part and cold lower part" is avoided, and the user experience is improved.

The application discloses a kind of control method, device and thermostatic shower of water heater system, and relates to water heater technical field, the method includes: when detecting that user opens water, if the water temperature of hot water inlet is lower than preset temperature threshold, then control mixed water valve is adjusted to not less than 80% first opening degree;Based on the water flow of hot water inlet in real time acquisition calculation first pipeline in cold water has been discharged volume, and according to the remaining cold water volume in first pipeline calculation;When judging the discharge length of remaining cold water volume is equal to the switching time length of mixed water valve from first opening degree to second opening degree, control mixed water valve switches to second opening degree, so that the water temperature of water outlet is in the allowable fluctuation range corresponding to shower setting temperature. By draining with larger opening degree when water temperature is too low, the discharge speed of pipeline cold water can be improved, and by timely opening degree adjustment, the water temperature can be just in the allowable fluctuation range corresponding to shower setting temperature, to improve user experience.
