Buffer tanks are mechanical elements used to store Energy.
HVAC Buffer tanks are properly insulated steel tanks, and are used as energy containers within the piping network towhere energy is stored when availiable, and used later for feeding the heating or cooling terminal devices (fan coils, exchangers e.t.c.) of the hvac network.
Adding a buffer tank is as simple as adding water volume in the hvac network. The reasons to do that, varies depending on the application: -
In air-conditioning installations, buffer tanks are used to add water volume in order to prevent frequent starts and stops of the main energy source (chiller / heat pump). Chillers and heat pumps have built-in safety processes to follow before re-starting of the compressor, and there is a minimum idle time before next restart, and if the water temperature falls too quickly, there will be a time interval when there wil be energy needs (water temperature needs heating / cooling), but the heat pump will be waiting for next time interval. So we install a buffer tank in order to store energy to use if a minimum start / stop interval occurs.
Buffer tanks are a must in case of wood and biomass heating source (wood boilers, hydraulic fireplaces e.t.c.) . By adding a buffer tank in a biomass source heating installation , we split the two hydraulic circuits (boiler to buffer and buffer to house). Buffer tank addition also separates producer and consumer energy balance. During spring and fall months when heat is still needed, the biomass boiler will produce more energy than the house's needs. If the boiler is directly connected to the house, the produced energy will overheat the room temperature, and comfort is completely lost.
So we use a buffer tank to store the excess energy from the biomass boiler and use this energy after the biomass boiler will stop heating.
Buffer tanks are also used to store energy from the sun. They are combined to solar collectors and store the solar energy produced by the collectors, through a means of a pump circulating water from the collectors to the buffer. This installation also needs a defferential controller,
Buffer tanks gives us the ability to store solar power and use it for room heating or domestic hot water applications.
The room gets the amount of energy needed either by means of switching on a pump which sends the heating water from the buffer tank to the circuits, or more automated installations including electro-valves to control multiple domestic hot water circuits with multiple recirculation hydraulic sub networks.
Installation of a buffer tank in heat pump applications, should be only used to achieve the minimum necessary water volume and not more than that, because adding water volume to heat pump HVAC installations will make your system more "lazy" and heavier, and i believe some real cost raise will occur.
