OSB 38kw-40kw Air to Water Heat Pump
Efficient defrosting - with a buffer tank, the defrosting time is reduced. When the air source heat pump works in cold weather, the heat pump will frost. Defrosting is a problem to the indoor temperature. Because the unit needs to consume heat in the pipeline during reverse cooling, and in the absence of a buffer tank, the water in the water system is less, resulting in a longer defrosting time, which will cause the water temperature in the pipeline to be too low. Thus, the defrosting effect is not ideal.
If a buffer tank is installed, the defrosting process can be completed in a short time because there is a certain amount of heat energy in the tank, thus avoiding the fluctuation of indoor temperature caused by the defrosting of the unit, which is of great significance for stabilizing the terminal effect of the system.
A buffer tank can ensure the smooth flow of water in the heat pump system so that it can complete automatic exhaust, and avoid error alarm. We all know that in the return water system, circulating water enters from the upper part of the tank and discharges from the lower part, so that the gas in the water accumulates at the upper space of the tank. The pressure in the closed system will automatically force the gas to be discharged from the upper exhaust valve, so there will be no gas in the inlet of the water tank which is connected to the outlet of the buffer tank. Thus, the gas will not be brought into the heat pump system, which protects the impeller of the water pump and ensures the normal operation of the air source heat pump. If there is no buffer tank, it is very easy to cause switch failure and high-voltage alarm because of the presence of gas.
All in all, buffer tank is an important part of the air source heat pump system. Choosing a buffer tank with appropriate capacity according to the actual situation has many advantages. Therefore, some people regards it as an " energy storage tank" based on its functions.
