Abstract

The invention provides a solar heating system without without liquid medium. The solar heating system comprises a heat collection cavity, ventilation equipment and a heat exchange device, wherein the heat collection cavity comprises a top plate and a bottom plate; the top plate is a structural member made of transparent materials, and the bottom plate is a dark plate or a plate with a dark coating; and a gas medium in the heat collection cavity is heated through collection of solar energy by the heat collection cavity, and the heat collection cavity is further provided with an exhaust pipe and an air inlet pipe. The solar heating system has the beneficial effects that the installation cost of the heating system is reduced, and the problem of icing in winter is avoided.

Description

technical field [0001] The invention belongs to the technical field of solar heating, in particular to a solar heating system without liquid medium. Background technique [0002] The current solar heating systems mostly use water as the heat transfer medium, and water as the heat transfer medium has the following disadvantages: First, the installation and material selection of the pipelines in the system need to take into account the problems of sealing and water pressure, and it is necessary to use The pipe fittings lead to high installation cost of the system and it is difficult to obtain large-scale application; secondly, when the system is applied in an environment with a low outdoor environment, the water may freeze and affect the normal operation of the system. In order to ensure the system’s For normal operation, it is necessary to add antifreeze settings to pipelines and equipment, which undoubtedly increases the operating cost of the system, which is contrary to the...
