Active solar system optimization method suitable for building in cold plateau area

Abstract

The invention discloses an active solar system optimization method suitable for a building in a cold plateau area. The active solar system comprises a solar photothermal unit and a solar photovoltaic unit, wherein the solar photothermal unit provides a heat source for winter heating of the building through solar heat collection and an auxiliary heat source of an air source heat pump; the solar photovoltaic unit provides a power supply to a building electric appliance, the air source heat pump and a conveying water pump through photovoltaic power generation; and the solar photothermal unit and the solar photovoltaic unit are both arranged on a roof of the building. Aiming at the resource, weather and building characteristics of the cold plateau area, the invention proposes a proper building active solar utilization system, and uses the system coupling relation and the energy flow balance restraint condition for building a system optimization solution model based on the economy and the energy saving property to provide support for comprehensive application of multiple solar technologies to the building in the cold plateau area, so that the application of a solar compound system is promoted.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an active solar energy system optimization method suitable for buildings in plateau cold regions. Background technique [0002] With the rapid growth of building scale on the Qinghai-Tibet Plateau, the shortage of energy supply for traditional buildings and the fragile ecological environment have become prominent factors restricting the development of the plateau area. The solar energy resources in the Qinghai-Tibet Plateau are extremely rich, and have the resource potential of large-scale development and utilization of solar energy. Therefore, how to efficiently and high-quality utilize the abundant solar energy resources in this area and build low-energy buildings will become an important development direction of plateau town construction. [0003] In recent years, solar technology has developed rapidly, and at the same time, the price of solar energy utilizat...
