Abstract

The invention relates to a double-loop solar heating and heat exchanging combined device. A plurality of double-flow-channel heat transferring units are arranged in parallel. Each double-flow-channel heat transferring unit is internally provided with two flow channels. Every two flow channels are partitioned through thin metal walls. The upper end and the lower end of one flow channel are connected with an upper collecting pipe and a lower collecting pipe of an auxiliary heat source loop, and the upper end and the lower end of the other flow channel are connected with an upper collecting pipe and a lower collecting pipe of a solar loop. Two working modes are adopted for the device, one mode is a heating mode, and the other mode is a heat exchanging mode. The heating mode is further divided into three operating modes, the operating modes can be selected according to the weather situation, heat dissipation cladding is adopted for the heating season, and the heat provided by the solar energy or an auxiliary heat source is released into a room through the heat dissipation cladding. According to the heat exchanging mode, in the non-heating season, the heat dissipation clapping is changed to be heat preservation cladding, and in the double-flow-channel heat transferring units, the heat in the solar loop is transferred to the auxiliary heat source loop. The double-loop solar heating and heat exchanging combined device can be combined with a conventional concentrated heating system, solar energy is fully utilized, the system is simplified, energy efficiency is improved, and integration of the solar energy and a building is achieved.

Description

technical field [0001] The invention relates to a solar heating device, in particular to a dual-loop solar heating and heat exchange compound device. Background technique [0002] Solar energy is a kind of renewable clean energy and an important energy source for the sustainable development of human beings. The use of solar energy and building integration for building heating can achieve good economic benefits and protect the environment. A radiator is an essential component in a heating system. In the traditional central heating system, the heat in the circulating hot water is generally provided by the boiler, which consumes a large amount of fossil energy and causes serious environmental pollution, which is one of the sources of smog. The use of solar energy as a heat source can greatly reduce the conventional energy consumption and improve the economy and energy saving of the heating system. The existing solar heating system generally stores the heat collected by the so...
