Generally speaking, if the pipeline from the water tank to the collector of a domestic flat panel solar water heater is relatively short, for example only three to five meters long, the fluid will not flow. will generally not flow if the pipeline. is relatively long, it can add an expansion tank to the pipe. When adding this expansion tank, try not to let the fluid escape. After installation, simply add enough water to the pipe. A small expansion tank can be used for domestic solar water heaters.
Classification of expansion tanks
No, these are two products with different operating principles
The water heater Pressurized solar is A vacuum tube is used to absorb solar energy, and then the solar energy is converted into thermal energy. Heat is transferred to the water tank via the heat conduction tube inside the v tubeide to increase the water temperature in the water tank. then the pressure water tank is used to apply sufficient pressure to the water. This way, when we use hot water, we will feel as energetic as cold water.
The pressure tank is used in a closed water circulation system to balance the water volume and pressure to avoid frequent opening of the safety valve and frequent replenishment of the automatic water replenishment valve. In addition to the function of accommodating expansion water, the expansion tank can also function as a water replenishment tank. The expansion tank is filled with air to obtain a greater volume to accommodate the expansion water. Both high and low pressure expansion tanks can use them. own pressure to be connected in parallel to the Hydrate pressure stabilization system.
The vExpansion bases are divided into two types: airbag type and membrane type. When using the former, the water does not come into contact with the inner wall of the tank at all, therefore. it eliminates rust and secondary pollution of water quality. Most of the common products on the market from 2010 to now, whether domestic or foreign, are airbag type; the diaphragm type expansion tank is the first generation product in the industry; first days. Half of the inner wall of the tank is in direct contact with water during operation, making it easy to rust and cause serious damage. Affecting its lifespan, membrane expansion tanks have disappeared from the market.
