Solar combined type phase-changing heat-storing warming system

Abstract

The invention discloses a solar combined type phase-changing heat-storing warming system which mainly comprises a solar heat collector (1), an auxiliary heat source (2), a solar circulating pump (4), a phase-changing heat-storing tank (5), a plate heat exchanger (6) and a warming circulating pump (9) which are communicated with each other through water pipes and are adjusted by mounting valves; the solar heat collector is in serial connection or parallel connection with the auxiliary heat source; a phase-changing material within 0-100 DEG C is adopted for the phase-changing heat-storing tank according to the requirement; when the outlet water temperature of the solar heat collector reaches a warming temperature, the hot water of the solar heat collector is directly subjected to heat exchange with warming return water through the plate heat exchanger; when surplus heat exists, the heat is stored in the phase-changing heat-storing tank in advance; and when the solar radiation is insufficient, the surplus heat is subjected to the heat exchange with the warming return water. The solar combined type phase-changing heat-storing warming system utilizes the combined mode of various pipelines and valves of the solar heat collector and the heat-storing characteristics of high heat-storing quantity and stable temperature of the phase-changing heat-storing material to overcome the defect of unstable solar radiation, so that the time for starting the auxiliary heat source is shortened. The system is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to solar heating technology, in particular to a solar composite phase change thermal storage heating system. Background technique [0002] As a renewable and clean energy, solar energy has been widely concerned by people. With the continuous deterioration of the environment, a low-carbon and green living environment has become a long-term goal of global sustainable development. According to the needs of the living environment, building heating is a high-energy-consuming industry that must be faced in many cold regions. A large amount of energy consumption has led to an increase in energy use year by year. From the initial coal heating to the gas and heat pump heating in recent years, all of them are completed under the premise of consuming a large amount of basic energy. Therefore, seeking a new heating method centered on energy conservation and environmental protection, and replacing traditional energy with clean renewable energ...
