There are many liquid supply forms of coolant system. According to the requirements of the system, primary pump liquid supply system and secondary pump liquid supply system can be set.At present, the secondary pump liquid supply system is widely used. The most important part of the secondary pump liquid supply system is the intermediate circulating water tank. The size of the water tank has a great impact on the stability of the system and the energy consumption of the system operation.Here is some analysis on the function of the intermediate water tank:
The circulation mode of the intermediate water tank: the primary water tank circulates with the refrigeration host, and the secondary water tank circulates with the end cooling equipment. Generally, the primary side is a constant flow system and the secondary side is a variable flow system.
The requirements of the primary side for the water tank mainly involve the start and stop of the host. The host generally has a short loading time and cannot be started again after shutdown. The interval is generally not less than 15 minutes. Therefore, it is necessary to ensure the load at the corresponding time after the host is shut down.
According to the requirements of the secondary side for the water tank, the end load of the secondary side is not a stable value. It is necessary to ensure that the cooling load of the water tank can provide the end load during the use process or during the reaction time when the main engine is shut down and loaded.In this case, the system can operate stably, and there will be no temperature oscillation in both the host and the end.
In addition, how to save energy in the intermediate water tank also needs to be considered.Assuming that the water tank is an infinite carrier, it can be understood as a cold source with constant temperature. The host transmits the cooling capacity during off peak power, and the end obtains the cold source from the water tank at any time according to the production needs.The operation energy consumption of this refrigeration system is about to reach the lowest, and the selection of equipment can also choose an efficient refrigeration host, which is the most ideal energy-saving practice. However, the actual capacity of the water tank needs to consider its economy and the investment and return in a reasonable range. At least its static payback period is within 5 years.
To sum up, the selection of intermediate water tank needs to fully consider the attributes of the system and select a reasonable intermediate water tank to ensure the operation of the whole system. Glacial coolant focuses on the systematic application of coolant.
