Abstract

The present invention provides a rotary absorber for solving the fault existing in heat exchanging and energy lost of existing solar solid absorber. The rotary absorber includes a rotary wheel, a cooling device and a rotary device. The rotary absorber is characterized in that the rotary wheel includes a rotary wheel housing connected to the rotary device, a wheel body and front, rear block plates fixed on the two end surfaces of the wheel body. The wheel body includes a rotary shaft and a wheel hub which is disposed with radiate wedge-shaped absorb beds on the circumferential direction. A wedge-shaped mass transfer passage is disposed between each two adjacent wedge-shaped absorb beds, the radiate end circle of the wedge-shaped absorb bed is fixed on the inner wall of the rotary wheel housing; the two end surfaces of the wheel body and the rotary wheel housing form a round concave, the inner side of the front and rear cover plates are respectively disposed with round platforms having the same diameter with the round concave. The round platforms are disposed with V shape clapboard and bearing seat, and are embedded into the round concave of the rotary wheel housing to divide the two end surface of the wheel body into upper and lower two regions.

Description

technical field [0001] The invention relates to an adsorber of a refrigeration device, in particular to an adsorber of a solid adsorption refrigeration device powered by solar energy. Background technique [0002] Solid adsorption refrigeration is realized by the adsorption-desorption cycle that the microporous solid adsorbent adsorbs the refrigerant at a lower temperature and desorbs the refrigerant at a higher temperature. Compared with absorption refrigeration, which is also driven by thermal energy, under the condition of relatively low heat source temperature or relatively high condensation temperature, adsorption refrigeration has higher efficiency when using a suitable refrigerant pair. Therefore, adsorption refrigeration is extremely superior in the utilization of low-grade heat sources, such as solar energy. [0003] Generally, the adsorption refrigeration system includes two or more adsorbers, which are heated and cooled repeatedly by switching work, thus causing ...
