Water cold storage and ice cold storage are both a kind of cold storage technology, which is used to cool and store the cold energy by the refrigeration mechanism during the power valley when the power is low in the case of large power peak-to-valley difference, and release the stored cold energy during the peak power generation to meet the cooling demand.
The advantages of water storage include:
1. Large cold storage capacity, which can meet the large cooling demand.
2. As a cold storage medium, water has a large specific heat capacity and small temperature change, which can effectively reduce energy consumption.
3. The water system is simple, easy to maintain, and the operating cost is low.
4. Water is environmentally friendly, non-toxic and harmless, and does not pollute the environment.
The disadvantages of water cold storage are:
1. The water temperature is high, it is difficult to achieve large-capacity storage, and the cooling effect on large buildings is limited.
2. The water temperature is higher, the refrigeration efficiency is lower, and a larger refrigeration unit is required.
3. The water temperature is high, and the requirements for pipes and equipment are high, so it is necessary to use equipment and materials that can withstand high temperatures.
The advantages of ice storage include:
1. Large cold storage capacity, which can meet the large cooling demand.
2. As a cold storage medium, ice has a large specific heat capacity and small temperature change, which can effectively reduce energy consumption.
3. The ice storage system can achieve long-term refrigeration to meet the long-term cooling demand.
4. Ice storage system can reduce indoor temperature fluctuations and improve indoor comfort.
The disadvantages of ice storage are:
1. As a cold storage medium, ice needs to use special ice-making equipment and refrigeration units, and the investment cost is high.
2. The ice temperature is low, which is prone to icing problems, and requires regular maintenance and management.
3. The ice temperature is low, the requirements for pipes and equipment are high, and the equipment and materials that are resistant to low temperature need to be used.
