A mixed PCM storage air conditioning system comprises a PCM storage tank, an ice ‐ cold storage tank, a refrigera- tion unit, and a cooling supply unit (Figure 4).
In a TES system, a storage media is cooled during periods of low cooling demand and the stored cooling is used later to meet air-conditioning load or process cooling loads. Operating refrigeration chillers at night and displacing energy use from peak (day time) to off-peak periods when the energy is at a lower cost is the primary objective of TES system.

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.
