Overview

Ground source heat pump comprehensive application and metering platform. Ground source heat pump with buried pipes utilizes the relatively stable characteristics of underground soil at room temperature, and on the basis of investing a small amount of high-temperature energy, exchanges heat and cold with the ground through buried heat exchangers to achieve the purpose of cooling and heating. In winter, ground source heat pumps extract low-level thermal energy from the earth to provide heating to buildings, while storing cold energy in the soil for summer use; In summer, heat from buildings is transferred underground to provide cooling, while heat is stored in the soil for winter use. Therefore, ground source heat pump technology is an efficient, energy-saving, environmentally friendly, and sustainable air conditioning cold and heat source technology.
