Vacuum solar steam heat collection tube, steam heat collection plate, solar water-heating air conditioner device

Abstract

The invention discloses a vacuum solar vapor heat-collecting tube, a vapor heat-collection plate formed by the vacuum solar vapor heat-collecting tube, and a vapor hot water air conditioner, which is characterized in that a sealing end cover is positioned at the open end of a common vacuum solar heat-collecting tube; a plurality of vapor exhaust ports, a plurality of liquid inlet tubes and a standby pipe are positioned on the sealing end cover; a homocentric core tube is positioned in the intracavity of the inner pipe; a liquid membrane gap is formed between the core tube and the inner pipe; the outlet of the liquid inlet tube is introduced into the liquid membrane gap; an adjusting valve, controlled by liquid level in the pipe or the temperature of inner pipe wall, is connected in series with the liquid inlet tube; a plurality of heat-collecting tubes are positioned in parallel in a frame; the back face of the frame is lined with a reflector; a light transmission plate is positioned on the front face of the frame; the vapor exhaust ports converge in a vapor exhaust header; the liquid inlet tube converges in a liquid return header; the vapor exhaust header and the liquid return header are positioned in the frame and simultaneously the heat is preserved; the interfaces of the headers expose to the outside, forming a vapor heat-collection plate; the vapor exhaust header and the liquid return header of the vapor heat-collection plate are connected with a through hole vapor absorber and a water outlet at the bottom part of a water tank by a vapor transportation pipe and a liquid return pipe, forming a water heater; an absorption-type air conditioner is connected in series with the vapor transportation pipe; a steam boiler is connected in parallel between the vapor transportation pipe and the liquid return pipe, forming the hot water air conditioner.

Description

technical field

[0001] The invention belongs to the technical field of solar photothermal application, and relates to a solar heat collecting element, in particular to a solar heat collecting element which is vacuum-insulated and capable of rapidly generating steam. The present invention also relates to a flat-plate solar heat-collecting component composed of the heat-collecting element, and a water heater and an air-conditioning device composed of the same. Background technique

[0002] At present, the heat collecting elements widely used in solar water heating systems are mostly originated from Chinese patent 95215311.4, that is, "a new type of all-glass vacuum solar heat collecting tube", which consists of a transparent outer tube closed at one end and an inner tube closed at the same end. On the outside, the other open end is fused and sealed to form a vacuum insulation interlayer between the two tubes. The outer surface of the inner tube is coated with a solar selective...
