Against the backdrop of the “Dual Carbon” goals, ice storage cooling technology leverages the difference between peak and off-peak electricity rates to shift air conditioning electricity loads. An increasing number of commercial complexes, industrial parks, hospitals, and data centers are adopting ice storage cooling systems, making ice storage cooling equipment a key component in reducing energy costs. Today, we’ll discuss the advantages of using ice storage cooling equipment.
Key Advantages of Ice Storage Cooling Systems:
1. By taking advantage of peak-and-off-peak electricity rates, electricity costs for air conditioning operation can be significantly reduced. Ice is produced and stored during off-peak hours at night, and then melted to provide cooling during daytime peak hours, thereby reducing the power consumption of the main units during peak periods. Projects with high air conditioning loads—such as commercial complexes, hospitals, and industrial parks—see the most significant savings on electricity bills.
2. Reduce the installed capacity of the chiller units and power distribution system, thereby lowering the initial investment. Since peak cooling capacity is provided by ice, it is not necessary to select and install all chiller units based on the maximum instantaneous cooling load.
3. By helping the power grid manage peak and off-peak loads, ice storage cooling projects are eligible for policy subsidies and capacity rate discounts. As demand-side response equipment, many regions offer the following incentives for ice storage cooling projects: – reductions in capacity rates; – peak-shaving subsidies and energy-saving incentives, while also alleviating pressure on the regional power grid.
4. Emergency cooling capability. In the event of a power outage or chiller failure, the cooling capacity stored in the ice storage tank can provide cooling for a short period, maintaining the temperature in critical areas (server rooms, operating rooms, data centers) and enhancing system reliability.
5. The air conditioning system operates more stably, improving cooling efficiency. Defrosting ensures a stable supply of low-temperature chilled water, supports cooling across large temperature differentials, reduces the flow rate of the chilled water pump, and lowers the pump’s energy consumption; since ambient temperatures are lower at night, the chiller unit is more efficient at producing ice during nighttime operation.
6. Environmentally friendly and carbon-reducing, meeting green building certification requirements. By shifting electricity generation to nighttime off-peak hours, this approach reduces carbon emissions from peak-hour thermal power generation and can be used to apply for green building, energy efficiency, and carbon neutrality certifications.
