A solar coupled air source heat pump complementary heating system and control method

Abstract

The invention discloses a solar energy coupled air source heat pump complementary heating system and a control method. The heating system is composed of a solar heat collection system, an air source heat pump system, a hot water storage tank and terminal equipment. The hot water storage tank is connected between the two systems of the system. The solar heat collection system includes that the solar heat collector is connected to the hot water storage tank through pipelines, and the temperature probe T1 is set on the pipeline, and the temperature probe T2 and temperature probe T3 are respectively arranged on the upper and lower parts of the hot water storage tank, and the water outlet of the hot water storage tank The circulating water pump on the solar side is connected through the lower circulating pipe section, and the temperature probe T6 is installed at the water inlet of the circulating water pump. Install an electric two-way valve. The invention solves the problem of overheating and overcooling on the side of the solar heat collection cycle caused by the existing heating technology utilizing solar energy and air energy.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a solar energy coupled air source heat pump complementary heating system and a control method. Background technique [0002] In the western Sichuan region of my country, the altitude is mostly between 1000 and 4500m, and the climate is mainly severe cold and cold. It is a typical alpine region, and heating is an urgent problem to be solved locally. This type of area is also rich in solar energy resources, and the sunshine time is relatively long. If solar energy is used directly to heat buildings, it will be difficult to guarantee the stability of the heating system due to the intermittent nature of solar energy itself. Therefore, in actual projects using solar heating, a set of auxiliary heat sources is often designed for the system, of which the complementary heating system of air source heat pumps assisting solar heating is the main one. The system has the characteristics of ...
