Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to an ice storage control system with the next day energy consumption simulation function. Background technique [0002] Ice storage system: Ice storage air-conditioning uses the low-load power at night to make ice and store it in the ice storage device. The ice is melted during the day to release the stored cold energy, reducing the power load of air-conditioning and the installed capacity of the air-conditioning system during peak hours of the power grid. The commonly used working modes to meet the requirements of the cooling load are as follows: (1) ice-making mode of the dual-working condition refrigeration main engine; (2) cooling supply mode of the dual-working refrigeration main engine; (3) dual-working condition refrigeration main engine and ice storage (4) Ice storage tank cooling mode.
