Coupling heat supply system used for highway service area and heat supply method of coupling heat supply system

Abstract

The invention relates to a coupling heat supply system for a highway service area. The coupling heat supply system is composed of three parts including an air energy heat collecting device, a soil buried heat exchange device and a heat collecting device, wherein the air energy heat collecting device and the soil buried heat exchange device achieve heat exchange with the heat collecting device through the heat exchange devices. By means of the coupling heat supply system, a series mode is adopted for achieving running of a ground source heat pump and an air energy combined heat supply system, on one hand, the wind abandoning problem in the wind energy utilization process can be avoided, on the other hand, heat loads obtained in soil can be effectively reduced, balance of a soil layer temperature field is maintained, and the system can be used for well servicing the highway service area.

Description

technical field [0001] The invention belongs to the field of new energy, and in particular relates to a coupled heating system and a heating method for a high-speed service area. Background technique [0002] Energy and environmental issues are major social issues facing all countries in the world today. As the material basis for the development of modern society, energy is closely related to the development of the national economy. Therefore, the research, development and utilization of green new energy have become the common strategic goal of energy construction in all countries in the world. Rational use of energy, improvement of energy utilization and development of new green energy are of great significance to alleviating the energy shortage. [0003] Due to the particularity of their services, high-speed traffic buildings determine that they are within the scope of no municipal supporting facilities, which makes it necessary to build facilities such as heating boilers...

AI Technical Summary

Problems solved by technology

[0004] Wind energy is a renewable and clean energy, but this resource is significantly affected by regional and seasonal changes, and there are problems such as intermittency, instability and fluctuation. Wind energy has the defects of instability and intermittency, and soil heat sources can make up for the instability of wind energy alone. Sexual Disadvantages

[0005] In addition, the heat load of buildings in cold northern regions is relatively large, which can easily cause an imbalance of underground soil temperature. This imbalance of soil temperature has a great impact on the efficiency of the entire ground source heat pump system, and it will also destroy the underground ecological balance.
