In order to compensate for the excess volume of liquid in the heating system, an expanded tank must be installed. If the boiler is working properly, the liquid temperature should increase gradually as the boiler heats up. This increases the volume of liquid by 0.3% for every 10 °C. Therefore, if the temperature rises by 70 ° C, the initial volume in the media will increase by about 3%. Unfortunately, the liquid does not compress, and therefore, in the absence of additional devices that remove the volume, sooner or later the system will become unusable. In order to prevent destruction, it is necessary to use expansion tanks.Expansion tanks are divided into:- open type;- closed type.An expansion pressure tank is used for a closed liquid circulation system in order to compensate for thermal expansion due to changes in liquid temperatures (cooling, heating).The tanks are separated by a membrane into water and gas chambers. When the water begins to heat up and expand, it begins to enter the first water chamber, and when cooled, it enters the system back. Both chambers have a constant pressure of the same, so the tightness does not change. When expansion pressure tanks first appeared, the need for installation of closed systems disappeared.The advantages of such systems include:- no corrosion (this occurs due to the circulation of water without oxygen and other gases).- long service life of the equipment and pipeline - the ability to use the system at high pressure - no need to recharge the system (there is no leakage of water in a closed system, unlike open ones)- no need to protect against freezing (the system operates all year round, as they must be placed in the boiler room)If a closed system is filled to the limit with a thermal carrier, even with a small increase in volume during thermal expansion, an emergency pressure increase occurs. This happens due to the actuation of the safety valve, which is located in the system, while the excess part will pour out. The container must be selected so that the expansion of heat does not lead to an increase in pressure in the systems above the actuation pressure of the safety valve.You need to calculate the required volume using a special formula. After calculating the volume, you need to select an expansion tank for heating. Try new casino games with 1xbet promo code today for 100% bonus up to $100 on selected new releases.
