Geothermal Heat Pump System

Introduction to Ground-Source Heat Pump Systems

A ground-source heat pump is a device that utilizes shallow geothermal energy and, by inputting a small amount of high-quality energy (such as electricity), facilitates the transfer of low-grade thermal energy to high-grade thermal energy. Typically, for every 1 kWh of energy consumed, a ground-source heat pump can deliver more than 4 kWh of heating or cooling to the user.
A ground-source heat pump is a central heating and air-conditioning system that uses the earth’s subsurface, soil strata, groundwater, or surface water as a low-temperature heat source. It consists of a water-to-ground-source heat pump unit, a geothermal energy exchange system, and an indoor building system. Depending on the configuration of the geothermal energy exchange system, ground-source heat pump systems are classified into buried-pipe ground-source heat pump systems, groundwater ground-source heat pump systems, and surface-water ground-source heat pump systems.

　　Project Overview

　　This project is located in the Baoji Economic and Technological Development Zone and involves a ground-source heat pump central air-conditioning system for the duty and comprehensive building and the experimental monitoring building of the pilot-scale workshop at the Baoji Baoding Environmental Technology R&D Base.

　　The total cooling load for this project is 1,155 kW, the total heating load is 930 kW, and the total chilled/heated area is approximately 13,000 m². A ground-source heat pump system is employed to provide cooling in summer and heating in winter.

　　Process Principle

　　A ground-source heat pump system extracts geothermal energy from the environment—such as soil, groundwater, and surface water—and transfers heat from the building to the environment, thereby providing cooling for the building.
