Abstract

The invention mainly provides a heating power switching system for solar thermal collector heat collection pipes. The heating power switching system mainly comprises a first solar thermal collector, a second solar thermal collector, a first valve, a second valve, a third valve, a fourth valve, a heat-carrying working medium inlet and a heat-carrying working medium outlet. The heat-carrying working medium inlet is connected with the first valve and the second valve through a heat pump working medium circulating pipe. The first valve is connected with one end of the fourth valve and one end of the first solar thermal collector. The other end of the first solar thermal collector is connected with one end of the second solar thermal collector. The other end of the second solar thermal collector is connected with the second valve and one end of the third valve. The other end of the fourth valve is connected with the other end of the third valve. The other end of the third valve is connected with the heat-carrying working medium outlet through a heat pump working medium circulating pipe. The heating power switching system is simple in structure principle, the purpose of heating power state switching can be achieved by changing the flow direction of heat-carrying working media in a heat production circulating loop, the service life of the heat collection pipes is prolonged, and operational reliability of a heat production circulating loop system is improved.

Description

technical field [0001] The invention relates to the field of solar thermal collectors, in particular to a thermal switching system of a solar thermal collector heat collecting tube. Background technique [0002] A solar collector is a device that converts the radiant energy of the sun into thermal energy. Since the solar energy is relatively scattered, we must try to concentrate it, so the collector is a key part of various solar energy installations. Due to different uses, collectors and their matching system types are divided into many types with different names, such as solar cookers for cooking, solar water heaters for producing hot water, solar dryers for drying items, Solar furnaces for smelting metals, as well as solar houses, solar thermal power plants, solar desalinators, and more. A solar collector is a device that absorbs solar radiation and transfers the generated thermal energy to a heat transfer medium. This short definition contains rich meanings: first: a ...
