Abstract

Abstract Energy issues play an increasingly important role in national security and economic development. The country has put forward the policy of building energy-saving and land-saving buildings. The application of the comprehensive utilization of renewable energy in the construction field has gradually become a need for technical progress and industry development. With the official promulgation and implementation of the Renewable Energy Law in 2006, the application of solar energy, geothermal energy, and other related renewable energy in the construction industry has attracted more and more attention. However, the scope of practical application is currently limited to solar energy alone to supply domestic hot water, power generation, or ground source heat pump system heating and cooling. The actual engineering cases of the combined operation of the two are relatively few, and the unreasonable joint operation mode leads to low system efficiency. In this paper, the combined application system of solar heat utilization and ground source heat pump is elaborated and analyzed in detail, from the technical feasibility, system efficiency, and other aspects of the analysis. It emphasizes the necessity and development prospect of the comprehensive utilization of renewable energy.
