The energy flow density of soil is small, 20–40W/m 2, generally 25W/m 2. This determines that when the soil is only used as the low-level heat source of the heat pump, its load should not be too large. Generally, it is only used when the load is no more than 1 MW. In addition, ground source heat pump has certain area requirements.
