Abstract

The invention discloses an evacuated solar energy steam heat collecting pipe, a steam heat collecting board and a steam hot water air conditioner which are composed of the evacuated solar energy steam heat collecting pipe. An open end of the evacuated solar energy steam heat collecting pipe provided with a double-layer jacket is provided with a sealing end cover, and on the sealing end cover a steam discharging port and an liquid intake pipe are provided; an inner cavity of an inner tube is provided with a core tube; a stenochasmus medium liquid membrane layer is formed between the core tube and the inner tube; the liquid intake pipe is serially connected to an adjuster for regulating the status of liquid feed. A plurality of the steam heat collecting pipes are arranged side by side on a framework provided with a reflecting board lined at the back and a transmitting board arranged in the front; the steam discharging ports are gathered to an exhaust manifold while the liquid intake pipes to a return liquid manifold; the exhaust manifold and the return liquid manifold are positioned for heat preservation in the framework with interfaces thereof exposed to form a heat collecting board generating steam. The exhaust manifold and the return liquid manifold of the steam heat collecting board are respectively connected with a water tank to form a steam-heating water heater / or connected with a condensation heat exchanger in a heat receiver to form the water heater or the heater of superconductive heat transmission through a steam transport pipe and a return liquid pipe. An absorption air conditioner is serially connected between the steam transport pipe and the return liquid pipe to form a steam-source solar energy 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 medium steam. The invention also relates to a flat-plate solar heat collecting component composed of the heat collecting element, and a heating device, a heating device 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 in China are mostly based on 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 wi...

Problems solved by technology

Obviously, there are many limitations and deficiencies in this vacuum heat collecting tube: First, there is a large amount of water in the tube, large heat capacity, slow temperature rise, low water temperature, and is limited to producing hot water below 100 degrees, and generally works in the range of 40 degrees to 80 degrees It is easy to scale inside and inside the pipe, and cannot instantly and quickly generate high-temperature, high-energy steam of various media, so it is difficult to adapt to many target fields, such as water boilers, steam furnaces, steam source absorption refrigeration air conditioners, heating radiators, industrial drying equipment etc., the scope of application is narrow; second, cold and hot water rely on natural circulation with small power, large resistance, and short transportation distance, which leads to the need for the water tank to be placed on the top, which is not conducive to the integration with the building, and the forced circulation will lead to additional power consumption , therefore, the application method is single, the effect is limited, and it is difficult to realize the high-efficiency solar energy device of the split structure of the building integration
