Description

Pressure-bearing is forced two circulating solar energy hot water rooms

Technology neck city

A kind of pressure-bearing that the present invention relates in the solar thermal utilization is forced two circulating solar energy hot water rooms.

Background technology

Common large-scale solar water conservancy project journey, mostly be nature single cycle type, this mode has that the thermal efficiency is low, the shortcoming of easy fouling, though also the someone uses the single cycle mode of forcing, but the automatic control system that is adopted is all comparatively complicated, the low and easier fouling of system reliability.The commodity solar hot water system who sells on the market all is an external-heat now, that is: light → photic zone → vacuum (or air) layer → black solid heat-absorbing material → solid material (as fin) → heat transfer medium (or water).The thermal efficiency of this tempexature external heating water heater is low and manufacturing cost is higher, and the life-span of solid heat-sink shell is also shorter, and this just makes present commodity water heater price height, and the life-span is short, and efficient is low.

Summary of the invention

Purpose of the present invention, provide a kind of in heat, efficient, low, the lightweight pressure-bearing of price force two circulating solar energy hot water rooms.

The present invention solves the technical scheme that its technical problem takes: with plate with grid open cavities in the transparent plastic as light-passing board and heat-collecting core board, with porous wall water tank double as heat exchanger, the heat collector collector pipe is connected with hole on the water tank wall by pipeline, to wherein be full of black liquor, directly as the power supply of circulating pump, or the power supply of controlling circulating pump indirectly gets final product with solar panel.

The invention has the beneficial effects as follows: a plurality of holes are arranged on the water tank wall, can improve water tank intensity greatly like this under the situation of economical with materials, also make water tank itself become a heat exchanger, this way is at one stroke several getting.

Because the present invention adopts the bicirculating working method of pressure-bearing, water tank can be installed in from the user and use the nearest place of hot water, is exactly hot water as long as the user opens water pipe, and is very easy to use.

Because light-passing board of the present invention and heat-collecting core board adopt macromolecular material to make, thus can heat collector be done enough greatly according to the building needs, enough light, and good hail suppression performance is arranged.

Because the black liquor that is full of in the transparent polymer heat-collecting core board of the present invention is an extinction heat production material, is again heat transfer medium, so be zero distance to heat transfer medium after the light heat production; This internal heat type heat collector can improve photo-thermal conversion efficiency greatly, and can reduce thermal loss greatly.

Heat collector of the present invention both can be used to produce massive life hot water, again can flashing, wind proofing, in the winter time, after the thermal-arrest core is by solar energy heating, most of energy is used to produce hot water, the fraction energy enters the temperature rising that makes within doors within doors by the heat-insulation layer of thermal-arrest core back, thereby the house that it covered is again a large-sized solar greenhouse.

Thermal-arrest core of the present invention and solar panel synchronous working, thereby saved complicated automatic control system, both saved fund, improved the reliability of system again.

The present invention adopts bidirectional triode thyristor as the contactless gauge tap of the power supply of circulating pump, as the intelligent trigger signal source, has simple in structure, reliable operation, cost is low, automaticity is high characteristics with the fritter solar panel.

Pressure-bearing of the present invention, freeze proof, efficient, low-cost, resistive connection is dirty, be suitable for the torrid zone, temperate zone, frigid zone and extremely frigid zones and use.
