Principle of Buffer Tank Working With R290 Monoblock Inverter Heat Pumps

The integration of a buffer tank with a R290 monoblock inverter heat pump represents a modern and highly efficient approach to heating and cooling systems. This combination not only enhances the performance of the heat pump but also enables significant energy conservation and improves comfort levels within residential or commercial spaces.

Despite the numerous benefits of the buffer tank, it is not widely known, as most people are more familiar with traditional water tanks used in water heaters. So what exactly does a buffer tank do when paired with an inverter heat pump? Let's delve into more details about this.

What is Buffer Tank?

Buffer Tanks are commonly employed in HVAC systems to provide additional fluid volume, thereby preventing frequent cycling of heating or cooling equipment.

Function Of Buffer Tank:

The use of buffer tank can be broken down into three main parts:

Firstly, the buffer tank increases the amount of water in the heating system. In doing so, it balances the system, allowing for efficient operation by avoiding short cycles for the heat pump.

Secondly, the buffer tank enables both circuits of the heat pump system to work simultaneously and independently. These two circuits require different flow rates and temperatures for optimal functioning, so the buffer tank plays a crucial role in improving overall efficiency.

Lastly, during defrost cycles, the buffer tank contributes by utilizing its stored heat to promote defrost without needing to absorb heat from home radiators. This helps maintain efficiency during defrosting processes.

Advantages Of Buffer Tank Working With R290 Monoblock Inverter Heat Pumps

Increased Heat Pump Water Capacity

The most significant advantage is the improvement in water storage capacity. For multi-family households, relying solely on the heat pump for heating/cooling water may not be sufficient to meet the needs of the entire family within a short period of time. Therefore, incorporating a buffer tank with your heat pump is a wise solution to address the issue of prolonged waiting times for hot/cold water.

Shortened Operation Cycle

In the absence of a buffer tank, an inverter heat pump operates by turning on and off to provide heating/cooling. However, when equipped with a buffer tank, it effectively mitigates rapid and intermittent changes in water temperature settings by storing hot or cold water. This ensures a more consistent and comfortable output of water temperature.

Prevention of Rapid Temperature Changes

Due to limited water in the circulation pipeline, circulating water can quickly reach the set temperature and cause the unit to stop working immediately. After shutting down, circulating water rapidly cools down, resulting in quick fluctuations in water temperature over a short period of time. The inclusion of a buffer tank allows for storage of generated hot/cold water, thereby preventing rapid temperature changes.

Extension of Inverter Heat Pump Service Life

Without a buffer tank, constant adjustments through opening and closing occur within the heat pump system. During fluctuating spring and autumn seasons, this can lead to increased wear and tear on the heat pump which is detrimental to its long-term use.

Protect Inverter Heat Pump

In the heat pump's return water system, the water circulates, entering from the tank's upper section and exiting through the lower. Over time, the cumulative usage can lead to gas accumulation in the tank's upper space. However, with the utilization of a buffer tank, such concerns are mitigated. The buffer tank prevents gas from being compressed within the tank, safeguarding the pump's impeller and ensuring the seamless operation of the air source heat pump.

In summary, the principle of a buffer tank working with a R290 monoblock inverter heat pump relies on the complementary nature of these two components. The heat pump provides variable heating and cooling output, while the buffer tank stabilizes water temperature and reduces energy consumption. This combination offers a highly efficient and cost-effective solution for modern heating and cooling systems, ensuring both comfort and sustainability.
