Solar expansion vessel calculator.

Vapour in the expansion vessel itself is not wanted because the high temperature of the vapour damages the membrane. Expansion volume of the solar uid litres. The expansion vessel in a solar installation is placed on the pressure side of the circulation pump see figure 2. The expansion volume is calculated as follows.

Calculate the expansion vessel volume using the formula. Output of flexcon 800 liter expansion vessel 0 5 flexcon 1 000 liter expansion vessel 0 4. Nominal volume of the expansion vessel litres ve. On this point consider that a water column of 10 meters exerts a 1 bar pressure.

This is the pressure created by the static height hst of the system between the connection point of the flexcon expansion vessel and the highest point in metres of water column 1 metre water column 0 1 bar. Vn ve vv vd x pmax 1 pmax pprec vn. The temperature in the flexcon expansion vessel must remain above 10 ºc. Amount of solar uid stored in the expansion vessel.

Vapour pressure p d. The calculation is valid in the hypothesis that the initial pressure hydrostatic pressure on the expansion vessel is not higher than the pre charge pressure. Static pressure p st. Certifications and approvals expansion vessel.

This is the total capacity of the flexcon expansion vessel. Select the nearest bigger size from the expansion vessel line. It s possible to calculate the required volume of the expansion vessel. The formula to size the expansion vessels for solar systems is the following.

This prevents vapour from entering the expansion vessel as much as possible. Expansion vessels for pump applications. Ve n x va vv. During this period modern solar collectors may reach temperatures up to 200 c and consequently the fluid within the system can either evaporate or reach levels that can damage all the components within the solar energy system over time.

Prior to installation of the expansion vessel or prior to filling the heating circuit at the latest adjust the pressure in the expansion vessel from the pre charge value to ph min. Output of flexcon m 0 72.
