Question

What are the two main types of solar collectors and how do they work?

The two main types of solar collectors are flat plate collectors and vacuum tube collectors.
Flat plate collectors are designed for low temperature applications and use direct and diffuse solar radiation. They do not require continuous movement to track the sun and require little maintenance.
Vacuum tube collectors are based on evacuated tubes, which are made up of two concentric tubes with a vacuum in between. They are divided into three types: simple evacuated tubes, direct flow tubes, and heat pipe tubes.
Simple evacuated tubes are used only in thermosyphon collectors, which contain water. Direct flow tubes are used for both stand-alone and compact heaters with an integrated tank. Heat pipe tubes have a mechanism consisting of a closed tube into which a fluid with specific properties is introduced.

Ed · Answer

Os dois principais tipos de coletores solares são os coletores de placa plana e os coletores de tubo a vácuo.

Os coletores de placa plana são projetados para aplicações de baixa temperatura e utilizam radiação solar direta e difusa. Eles não requerem movimento contínuo para acompanhar o sol e exigem pouca manutenção.

Os coletores de tubo a vácuo são compostos por tubos evacuados, que consistem em dois tubos concêntricos com um vácuo entre eles. Eles são divididos em três tipos: tubos evacuados simples, tubos de fluxo direto e tubos de tubo de calor.

Os tubos evacuados simples são usados apenas em coletores termossifão, que contêm água. Os tubos de fluxo direto são usados tanto em aquecedores autônomos quanto em aquecedores compactos com um tanque integrado. Os tubos de tubo de calor possuem um mecanismo composto por um tubo fechado no qual um fluido com propriedades específicas é introduzido.
