Split solar water heating system

Abstract

The invention discloses a split solar water heating system. The split solar water heating system comprises a heat collector, a bearing coil pipe water tank, a circulating water inlet pipe and a circulating water return pipe, wherein the circulating water inlet pipe is connected with a circulating water inlet of a water tank, and the circulating water return pipe is connected with a circulating water outlet of the water tank; the heat collector is an indirect heat exchange type vacuum pipe heat collector, a heat exchange pipe is arranged inside the heat collector, and a heat exchange pipe connector communicates with the circulating water inlet pipe and the circulating water return pipe to form a loop ; water is supplemented for a heat collector header through an automatic water supplementing tank, the two ends of the header are each provided with a connector, and the connectors are connected with the water inlet pipe and the water return pipe correspondingly; the water inlet pipe and the water return pipe are connected with a coil pipe of the bearing coil pipe water tank so that a second loop can be formed; and starting and stopping of a circulating pump are controlled through a controller and a temperature sensing probe. The split solar water heating system is high in heat collection efficiency and long in service life, can effectively prevent the heat collector from being too hot, and can reduce the heat loss.

Description

technical field [0001] The invention relates to a split solar water heating system, which belongs to the field of solar heat utilization. Background technique [0002] With the development of society and economy, the problems of energy shortage and environmental pollution are becoming more and more prominent. It has become a social consensus to develop and utilize a large number of renewable energy sources to achieve a low-carbon economy. Photothermal utilization of solar energy is increasingly used in building domestic hot water and industrial heating projects. Most of the existing household solar water heating systems, especially split hot water systems, adopt two forms: one is to use U-shaped copper tube heat collectors for heat collection and pressure-bearing coil water tanks for heat storage, and the controller adopts The temperature difference circulation mode controls the opening and closing of the circulation pump, and the inside of the heat collector and the coil ...
