The following repeatedly lists some terms and definitions in GB/T 19409, GB 50366, NB/T 10097.
3.1
Shallow geothermal energy
Within a depth of.200m from the surface to the ground, the temperature stored in the water body, soil body, and rock is lower than 25 ℃, which can be improved by using heat pump technology.
Take geothermal energy for heating or cooling of buildings.
[NB/T 10097-2018, definition 2.1.6]
3.2
Water-source heat pump unit water-sourceheatpumps
A kind of water or well water, lake water, river water, sea water or domestic sewage and industrial waste water or common pipeline that flows in buried pipes in circulation
Water is the source of cold (heat), equipment for making cold (hot) wind or cold (hot) water.
Note. The "water" of the water source heat pump also includes "saline" or fluids of similar functions (such as "ethylene glycol aqueous solution"), depending on the heat source fluid used by the unit.
[GB/T 19409-2013, definition 3.1]
3.3
Ground source heat pump system ground-sourceheatpumpsystem
Using rock and soil, groundwater or surface water as the low-temperature heat source, it is composed of water source heat pump unit, geothermal energy exchange system, and system in the building.
