Solar heat storage heating system and heating control method thereof

Abstract

The invention discloses a solar heat storage heating system. The solar heat storage heating system comprises a solar heat collection device, a heat storage water tank and a heating room. A heating device is arranged in the heating room. A heat exchange coil is arranged in the heat storage water tank. The solar heat collection device is connected with the heat exchange coil. A heat collection return water pipe is provided with a heat collection circulating pump. The water storage water tank is connected with the heating device in the heating room. A heat supply circulating pump is arranged on aheat supply water inlet pipe. The solar heat storage heating system stores excessive heat generated by the solar heat collection device during daylight in the heat storage water tank and conducts heating supply through stored solar energy at night, so that solar energy is utilized more effectively and fully. The invention further discloses a heating control method of the solar heat storage heating system. The heating control method comprises a heat storage method and a heat using method. The heating control method conducts distinguished control according to the thermal inertia of the heatingdevice. Accurate adjustment on the heating water temperature is realized easily and conveniently through an electric three-way ball valve and bypass pipelines on the basis of slow water temperature change of the heat storage water tank.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a solar heating control system. Background technique [0002] Northwest my country has a vast territory, drought and little rain, and rich solar energy resources. As a clean and renewable energy source, solar energy has the advantages of being inexhaustible and inexhaustible. In the northwestern part of my country, passive solar houses are mostly used in architectural design, and the room temperature is directly heated by making full use of solar radiation heat during the day. The traditional small solar heating system lacks effective water supply temperature control methods, resulting in high heating temperature during the daytime when the solar radiation intensity is high, superimposed with the room temperature, causing the room temperature to overheat during the day, and the window has to be opened, resulting in The waste of solar energy is less economical. ...
