Abstract: A heat-pump air conditioner having a dehumidification function comprises a heat-pump host (1), a cooling/heating circulation system (2), an indoor heat exchanger (3) and an indoor dehumidifier with adjustable temperature (4), wherein the heat-pump host (1) comprises a compressor (11), a first heat exchanger (12), a fan (13), a second heat exchanger, a four-way valve (14) and an expansion valve (15), and the cooling/heating circulation system (2) comprises a supply cooling/heating pipeline (21), a return cooling/heating pipeline (22), a third heat exchanger, a water distribution and collection device (23) and a circulating water pump (24). A cooling function of the dehumidifier with adjustable temperature (4) and the heat-pump host (1) works in conjunction with temperature adjustment and dehumidification, which achieves a synergetic effect.

Abstract: Disclosed is a temperature control system coupled with a heat pump water heater. The temperature control system comprises a heat exchange unit, a heat exchanger, a supply water pipeline, a return water pipeline, a room temperature control apparatus, a heat pump water heater, a buffer water tank and a water pump. The heat pump water heater comprises a temperature-rise water tank, a heat pump evaporator and a compressor. The heat pump evaporator is coupled to the return or supply water pipeline. In a coupled form, an outdoor unit of the heat pump water heater is replaced by the heat exchange unit via a circulating water body, so that a room temperature adjustment system shares the heat exchange unit with a hot water supply system. Moreover, multiple households can share one heat exchange unit, which is of great significance for apartments and rental houses.

Abstract: The invention discloses a method for preparing a ruthenium rotary sputtering target, including the following steps: S100: manually press molding: putting ruthenium powder into a mold, and manually pressurizing the ruthenium powder to form the ruthenium powder into a relative density is a first preformed target with a first preset density; S200: vacuum hot pressing, placing the first stage target together with the mold into a vacuum hot press for processing to obtain a second preformed target with a relative density of the second preset density The preformed target material, and the second preset density is bigger than the first preset density; S300: hot isostatic pressing, the second preformed target material is put into the hot isostatic pressing for processing, and the relative density of the third preformed target is obtained. Assuming the density of the forming target, the third preset density is bigger than the second preset density, and the third preset density is exceeded 99.5%.
