separated pressure solar heater system

Features: This system is including solar collector.storage tank. working station . The solar collector is consisted of copper pipe vacuum tube and header, so its of great efficiency ofheat collecting. 1.The solar collector and thewater tank are separated , the whole system runs under the forced pressure. 2.The solar collector could bemounted on the balcony veranda, the southern wall .sloping roof or awning andthe water tank can be installed anywhere. 3.The heat pipe vacuum tubecollector is a two circuit system, free of freezing and could be used all the year. 4.The metal super_______conducting vacuum heat collector is used , no water in the tube ,no burstingand could be used as usual under minus 50 5.This system is convenient to transport. The principle of the system: 1. The collector applies the fourthgeneration of solar collector______ heat pipe vacuum collector to transfer thesolar power to heat energy. 2. When the temperature of TC ( thetemperature of the collector) is higher than that of TR( the temperature of thewater tank),the controlling device will start the circulation pump. 3 . During the working of circulation pump,when the temperature difference is less than a set point, the circulation pumpwill stop. 4. When TR (the temperature of the watertank) reaches the highest of set point. the controlling device will close thecirculation pump. 5. The electrical heating device will makethe temperature of the water tank stay at a set point automatically.
