The utility model provides high -efficient stainless steel condensing boiler, including base, the base top is provided with boiler body, one side of boiler body is equipped with the air blower, forms the combustion chamber of airtightness in boiler body, the top of air blower is equipped with the burner, and the output end of burner is equipped with the combustion head, and the combustion head is located the above of combustion chamber, and the heat exchange device is provided with the communicating pipe in combustion chamber below one side top, and the communicating pipe is linked together with the combustion chamber, the heat exchange device is equipped with the return flue pipe in the side away from communicating pipe, and the return flue pipe output end connects the rear smoke case, and the rear smoke case is fixed on the side wall of boiler body, and the rear smoke case top is equipped with the smoke outlet, the flue gas is divided into three return, and the first return combustion head carries out heating, and the second return flue gas passes through the communicating pipe and enters the front smoke case, reaches the effect that the full heat exchange, and the flue gas releases the condensing heat in the middle lower part of heat exchange sheet, and the third return flue gas enters the rear smoke case through the return flue pipe, and forms the even airflow field in the combustion chamber, ensures the even distribution of heat.

The utility model provides a building environment regulation and control system, a multi-radiation tail end unit comprises a top plate radiation tail end module, a wall surface radiation tail end module and a floor radiation tail end module, a heat pump unit comprises a buffer water tank and a heat pump host, and a primary side water return pipeline between the buffer water tank and the heat pump host is provided with a three-way switching valve; on one hand, a multi-dimensional and large-area radiation heat exchange network structure is formed by integrating the top plate, the wall and the ground, an extremely uniform, stable and dead-corner-free indoor temperature field can be built, the problems that a traditional convection air conditioner is not uniform in cold and heat and air blowing feelings exist are solved, and the problem that application of a single radiation surface is limited is solved; and on the other hand, the sky radiation refrigeration unit is integrated, so that the sky radiation refrigeration unit can be switched with the radiation heat exchange network structure, free cold sources in nature are utilized, a heat pump can be greatly replaced or assisted for refrigeration under proper meteorological conditions, and the energy consumption of building regulation and control in the refrigeration season is reduced.

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.

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.
