Cavity air duct solar air heat collection and air supply system

Abstract

The invention relates to a cavity type air flue solar air heat-collection and air supply system, belonging to the field of solar heating and air-supply devices and particularly relates to an air supply system for supplying warm air indoors by heating the air by utilizing the solar energy. The cavity type air flue solar air heat-collection and air supply system comprises a solar air heat collector and an indoor hanging machine (8) of a fan heater, wherein an air outlet (4) of a heat collector of the solar air heat collector is connected with an air inlet (25) of the fan heater. The cavity type air flue solar air heat-collection and air supply system is characterized in that a wind source conversion device is additionally arranged between the air outlet (4) of the heat collector and the air inlet (25) of the fan heater. According to the cavity type air flue solar air heat-collection and air supply system, the heat is collected by utilizing the cavity type multi-air-flue air heat collector, the air heat-collection efficiency is firstly improved, the supplying effect of the outdoor warm wind is guaranteed, and the free conversion of different wind sources can be easily realized by utilizing the wind source conversion device.

Description

technical field [0001] The utility model relates to a cavity-type air duct solar energy air heat collection and air supply system, which belongs to the field of solar energy heating and air heating equipment, and specifically relates to an air supply system for supplying indoor warm air by heating air with solar energy. Background technique [0002] The solar hot air heating device is a device that uses solar energy to heat the air, and then uses the heated air to heat the room. However, since the use of solar energy has a great relationship with natural factors such as weather and temperature, when the outdoor wind is not suitable for the supply of warm air, it will inevitably affect the supply of solar warm air, which requires other air supply channels. Therefore, the air supply system of the solar hot air heating device needs to be able to use both outdoor wind for heating and indoor wind or other wind sources for warm air supply. However, the current indoor warm air supp...

However, since the use of solar energy has a great relationship with natural factors such as weather and temperature, when the outdoor wind is not suitable for the supply of warm air, it will inevitably affect the supply of solar warm air, which requires other air supply channels. Therefore, the air supply system of the solar hot air heating device needs to be able to use both outdoor wind for heating and indoor wind or other wind sources for warm air supply. However, the current indoor warm air supply system cannot be flexible due to the unreasonable system structure design. The free conversion between various wind sources is realized, and the selection of indoor wind and outdoor wind is not flexible and convenient; in addition, the heat collection effect of the existing solar collectors is not ideal, which makes the existing air supply system The warm air supply effect can not better meet the warm air supply demand in various weather
