Pipeline hot water circulation type solar water heating system

Abstract

The invention discloses a pipeline hot water circulation type solar water heating system. The system comprises a heat collector, a water tank, a temperature difference compensator, a permanent magnet motor circulating pump, an electromagnetic valve and two pipelines, the temperature difference compensator, the permanent magnet motor circulating pump, the electromagnetic valve and the two pipelines are arranged between the water tank of the solar water heating system and a water-used device, one pipeline is connected with the water-used device, and the other pipeline is connected with the temperature difference compensator through the permanent magnet motor circulating pump. According to the pipeline hot water circulation type solar water heating system, the use effect of a solar water heater is improved, the water and electricity are saved, and the common problem of pipeline frozen blocking in winter in terms of the solar water heater is avoided.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a pipeline hot water circulation solar water heating system. Background technique [0002] At present, household solar water heaters on the market are composed of a heat collector, a water tank, a pipeline and water equipment. The pipeline is the water flow channel for water supply / outlet to the water tank: when water needs to be supplied to the water tank, the pipeline becomes a water tank When using water equipment, the pipeline becomes a hot water outlet channel; if the water in the water tank does not reach the operating temperature, it is necessary to use an electric heater installed in the water tank to heat the water in the water tank; [0003] Since there is only one pipeline as the water supply / outflow channel, there is usually low temperature water in the pipeline that does not enter the water tank; when users use hot water, they must drain the cold water in the pipeline before u...
