We also found that a gap is generated between the cold heat supply by the
geothermal heat pump and the heat demand of the store C. After we analyzed
the cooling load of the store C. we found that when the average outside temperature exceeded 30 °C, the cooling load of the store C exceeded the capacity of
the geothermal heat pump, and unable to supply enough cold heat during the store
operating time zone in summer (Fig. 37.12).
