What role does the buffer water tank play in the system? How to choose the appropriate buffer water tank capacity?
If the system is equipped with a buffer water tank, during the defrosting process, due to a certain temperature inside the water tank, defrosting can be completed in a short time with low heat consumption, avoiding fluctuations in indoor temperature caused by host defrosting, and ensuring stable operation of the system.
There are two installation methods for buffer water tanks in the water system. There is a name called coupling tank in the system, which mainly solves the problem of hydraulic balance in the system. Different circulation pipelines are separated in the system to make all circulation pipelines interconnected. The selection of the capacity of the buffer water tank ensures that the efficiency of the system reaches a stable water flow rate, and the selection of the buffer water tank system needs to ensure a small water flow rate of the system, It is generally recommended that the capacity of the main system’s buffer water tank be slightly smaller than that of the auxiliary system’s buffer water tank.
The cooling capacity of the main unit can be selected based on empirical values (range: 3-5 L/KW). The buffer slot is the same as the connection slot. The buffer water tank can be understood as a large coupling tank. It can achieve the separation of primary and secondary systems, as well as store domestic hot water. When installing a buffer water tank, the gas in the system will continuously accumulate in the upper part of the buffer water tank, and then automatically exhaust through the exhaust valve on the upper part of the buffer water tank. The exhaust effect is obvious, ensuring the normal operation of the system.
