Description

U-Pipe Vacuum Tube Solar Collector Working principle: Single-flow connection: Time for water or conducting oil staying in the U collector tube is long, so the temperature rises highly. When the temperature of water or conducting oil raises to the upper limit of the setting temperature, the temperature circulating pump will start the internal circulation in U collector tube. Water or conducting oil will pass though each U-pipe to enter into the water tank. When the temperature sensor at the end of U-pipe collector drops to the setting lower limit, the circulating pump will stop work. The water or conducting oil in the U-pipe in front end and in the middle fall at the same time, so the heat loss is low and the efficiency is high. Specification: 1.
