The present invention relates to a vacuum circulating tube for solar water-heater, and is characterized by that it uses an internal tubbe, an external tube and a connection portion of both internal and external tubes to form a closed concentric axle sleeve mechanism. The sandwich formed from internal tube, external tube and their connection portion of …
There are basically two types of collectors, stationary and tracking [3] (Fig. 1).Different collector configurations can help to obtain a large range of temperature for example, 20–80 °C is the operating temperature range of a flat plate collector (FPC) [4] and 50–200 °C is for an evacuated tube solar collector (ETSC) [5], [6].The most productive …
To promote the transition to clean heating methods in rural areas and improve solar energy utilization efficiency, two new types of solar water collectors with …
According to EIU (2020), a report by The Economist Intelligence Unit, China''s "dual circulation" strategy "aims to foster resilience by emphasizing the "internal" circulation of the domestic economy over the "external" circulation of the global economy". CGTN (2020a), an influential English language newspaper from China, states,
As an important part of the processing of industrial and agricultural products, drying is extensively applied in all areas of economic production [1, 2].The search for efficient and energy saving drying technology meets the needs of economic development [3, 4].Vapor compression heat pumps, as one of the most efficient heating technologies, …

Deng Xiaoping once described the great advantage of the socialist system as "concentrating power to do big things.". From its expansive overseas investments into inland and sea infrastructure to its domestic drive for technological self-sufficiency, the Chinese Communist Party (CCP) under the rule of Xi Jinping has shown an impressive …
Fig. 1 shows a schematic for the layout of a vacuum-pump-assisted TSS integrated with a solar collector. The main components of the system include a vacuum pump, a three-effect TSS module, and three water tanks. When operated under vacuum, the distillation process occurs in the three still chambers (denoted as #1, #2, and #3 in …
This study included application of two techniques of solar-energy to heat the slurry within the LCTD. The first one was to heat the digester 1 consisted of a solar-greenhouse integrated with a north wall, SWH system, capillary heat exchanger (HE), a layer of sand as a good medium for heat storage and a layer of cotton glass wool …
