The function of the buffer tank
1. If the buffer water tank is not used, the water chiller will frequently start and stop. Due to the limited amount of circulating water in the loop, it will cause the water chiller to reach the design temperature in a short period of time, and the water chiller will stop working, and then within a short period of time, the water temperature will reach the start condition of the host, and the host will start again. Startup, so frequent startup will greatly reduce the life of the host and waste power. Not only the buffer tank is needed, but the capacity of the tank is preferably larger.
2. Efficient defrost, short defrost time.
When it is used in severe winter, especially between -3 ℃ ～ 5 ℃, frosting of the host is obvious, and the effect of defrosting on indoor temperature is a headache. Because the unit needs to consume the heat in the pipeline during reverse cooling, if the water system has less water, the defrosting time will increase, and the water temperature in the pipeline will be lower, and the defrosting effect will not be good. If a buffer water tank is installed, during the defrosting process, because the water tank has a certain temperature, the defrosting can be completed in a short time, and the heat consumption is small, which avoids the indoor temperature caused by the defrosting of the host. Fluctuation changes have a great effect on the end effect of the stable system.
