Buffer capacity (definition)

Buffer capacity is a device designed to accumulate and store excess thermal energy in heating, cooling and hot water supply systems. The main function of the buffer tank is to smooth out fluctuations in temperature and pressure of the coolant, which increases the efficiency and stability of the system.

Main components and operating principle of the buffer tank:

1. Frame - a sealed container made of material resistant to high temperatures and pressure. The inner surface can be coated with an anti-corrosion layer.
2. thermal insulation - a layer of insulating material surrounding the housing, which minimizes heat loss and keeps the coolant in the buffer tank hot for a long time.
3. Connection pipes - inlet and outlet connections through which the coolant enters and exits the tank, integrating with the main heating or cooling system.
4. Sensors and valves — temperature and pressure control devices that help control the charging and discharging process of the container, ensuring safe operation of the system.

Buffer capacity functions:

• Thermal energy storage — the buffer tank accumulates excess heat produced by a heat source (for example, a boiler or heat pump) and releases it into the system as needed, which reduces equipment on and off cycles.
• Smoothing out temperature fluctuations — helps maintain a stable temperature in the system, preventing sudden changes that could negatively affect the operation of the equipment and the comfort of users.
• Increasing system efficiency — allows you to use thermal energy more rationally, reducing fuel consumption and increasing the efficiency of the heating or cooling system.

Application of buffer tanks:

Buffer tanks are widely used in heating systems with solid fuel and gas boilers, heat pumps, solar collectors and other heat sources. They are also used in hot water and cooling systems, ensuring stable and efficient operation of utility systems in residential, commercial and industrial buildings.

Due to the dynamic setting of the work pellet boiler in a system with a four-way valve, use of a buffer tank for accumulation thermal energy not required.
