Heating-ventilating dual-purpose solar air collector

Abstract

The invention discloses a heating-ventilating dual-purpose solar air collector which comprises a cover plate, a metal outer frame, an inner frame, an absorber plate, an outer sealing plate, a temperature control switch, a draught fan, an upper air inlet and a lower air inlet. An air layer is arranged between the cover plate and the absorber plate of the collector; the outer sealing plate is movably connected to the top of the metal outer frame; the inner frame is fixed in the metal outer frame; a lateral insulation layer is arranged between the metal outer frame and the inner frame; the draught fan and the temperature control switch are separately arranged on the inner side of the upper air inlet in a pluggable manner; the draught fan and the temperature control switch are arranged in series to be electrically connected; the upper air inlet and the lower air inlet are separately connected with an upper indoor air inlet shield and a lower indoor air inlet shield; and a heat-isolating plate is further arranged on the inner side of the draught fan in a pluggable manner. Through serial connection between the built-in draught fan and the temperature control switch, start or stop of the draught fan is controlled through temperature, so that the heating-ventilating dual-purpose solar air collector is reliable in operation and safe and energy-saving. If the heating-ventilating dual-purpose solar air collector is used for heating in winter, only the upper and lower indoor air inlet shields require to be opened. If the heating-ventilating dual-purpose solar air collector is used for ventilating in summer, only the outer sealing plate and the lower indoor air inlet shield require to be opened.

Description

technical field [0001] The invention relates to the technical field of solar heat collectors, in particular to a heating-ventilation dual-purpose solar air heat collector. Background technique [0002] Solar collector is an important equipment in solar heating system. It can collect solar energy and convert it into heat energy. Currently, flat-plate solar collectors use air as the heat-collecting medium, which has the advantages of light weight, small pressure, no need for corrosion protection, and no need for heating. Increase the advantages of intermediate heat exchangers. [0003] At present, there is no dual-purpose solar air collector that can be used for heating and ventilation in the market, and there are often low heat collection efficiency, high production costs, complicated installation, inconvenient use, etc., which are not conducive to solar air collectors. promotional application. Contents of the invention [0004] The purpose of the present invention is to ...
