Separate Pressurized Solar Water Heater Made In China

Sunwe Solar water heating (SWH) or solar hot water (SHW) systems comprise several innovations and many mature renewable energy technologies that have been well established for many years. Solar water heater has been widely used in Greece, Turkey, Israel, Australia, Japan, Austria and China.

In a "compact" Solar water heating system the storage tank is horizontally mounted immediately above the solar collectors on the roof. No pumping is required as the hot water naturally rises into the tank through thermosiphon flow. In a "pump-circulated" system the storage tank is ground or floor mounted and is below the level of the collectors; A circulating pump moves water or heat transfer fluid between the tank and the collectors.

Solar water heater systems are designed to deliver hot water for most of the year. However, in winter there sometimes may not be sufficient solar heat gain to deliver sufficient hot water. In this case a gas or electric booster is normally used to heat the water.

Working Principle of Sunwe Solar Water Heater

1) Vacuum tube is composed of inner and outer glass pipe, inspiratory layer, vacuum space, inspriatory membrane. The surface of inner and outer glass tube is plated with selective absorption layer. The layer absorb the solar energy and turn it into heat energy, aluminum fins pass the heat energy to the heat pipe, the liquid medium in the heat pipe is heated by the heat energy, then turns into the gas medium, the gas medium flows up to the top of the heat pipe (condenser) and transfer the energy to the copper manifold header heat pipe. At the same time the gas medium turns into the liquid when cooled, then flows down. Keep recycling.

2) An electronic controoler measures the temperature of the solar collector and the water in the bottom of the storage tank. If the collector is hotter, meaning there is heat available. The controller supplies power to a circulation pump which pushes liquid which in circulation system circulating. The heat will transferred to storage tank via the liquid.
