Oil-water based staged solar heating method and device

Abstract

The invention discloses an oil-water based staged solar heating method and device. The device comprises a solar heat collection system, a temperature control system, an oil-water heat exchange systemand a user heating system. The solar heat collection system comprises solar heat collection pipes and groove type single-axis reflection heat collection plates, and heat conduction oil serves as a heat transfer medium. The temperature control system comprises an electric auxiliary heater and a temperature adjuster. The oil-water heat exchange system is located between the heat conduction oil and heating water. The heating water serves as a heat transfer medium of the user heating system. According to the oil-water based staged solar heating method and device, the dual loop system with heat collection and heating separated is adopted, the heat conduction oil cyclically absorbs solar energy in a solar heat collection field, the heat conduction oil and the heating water achieve heat energy exchange in the oil-water heat exchange system, and the heating task in the user heating system is completed; and the advantages of low heat losses and high stability are achieved.

Description

technical field [0001] The invention belongs to the technical field of solar heating, and in particular relates to a solar heating method and device based on oil-water classification. Background technique [0002] Solar heating is a technology that uses solar collectors to collect solar radiation and convert it into thermal energy for heating. The liquid medium is used as the heat transfer medium, and the heat is radiated to the room for heating through the cooling components in the user's room. [0003] Existing solar heating systems generally consist of solar collectors, hot water storage tanks, connecting pipelines, auxiliary heat sources, cooling components and control systems. The solar heating system uses water as heat collecting medium and heating medium, and has the advantages of simple operation and low price. Its disadvantages are: 1) The traditional solar heat collection system with water as the heat collection medium has a low utilization rate of solar energy; ...
