Normal-pressure overall-wall-mounted solar water heater

Abstract

The invention discloses a normal-pressure overall-wall-mounted solar water heater. The normal-pressure overall-wall-mounted solar water heater comprises a box body, vacuum pipes, a water inlet and outlet pipe, a circulation pressurization pipe, a self-priming pressurization pump, a three-way valve, a hot water pipe, a control cabinet and a water feed electromagnetic valve. The box body comprises a water tank and a heat collector, wherein the water tank and the heat collector are of an integrated structure, the vacuum pipes are arranged in the heat collector, and the opening ends of the vacuum pipes communicate with the water tank. A water inlet and outlet is formed in the side face of the water tank. The water inlet and outlet pipe is arranged in the control cabinet. One end of the water inlet and outlet pipe is connected with a water inlet port of the three-way valve, and the other end of the water inlet and outlet pipe is connected to the water tank. The water feed electromagnetic valve is installed on the water inlet and outlet pipe. Two water outlet ports of the three-way valve are connected with the circulation pressurization pipe and the hot water pipe correspondingly, the other end of the circulation pressurization pipe is connected to the water inlet and outlet pipe, the self-priming pressurization pump is installed on the circulation pressurization pipe, and a tap water pipe is connected to the water inlet and outlet pipe. The water tank and the heat collector of the normal-pressure overall-wall-mounted solar water heater both operate under the normal pressure, and therefore the normal-pressure overall-wall-mounted solar water heater is long in service life and high in hot water yield. (The system can be transversely / vertically installed and used).

Description

technical field [0001] The invention relates to a water heater, in particular to a normal-pressure integral wall-mounted solar water heater. Background technique [0002] A solar water heater is a device that converts sunlight energy into heat energy, and heats water from a low temperature to a high temperature to meet the needs of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. Vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Existing solar water heaters generally operate under pressure outdoors, which easily cause system damage during operation, have the defects of short service life, low hot water output rate, and high cost. Contents of the invention [0003] The object of the present invention is to provide an atmospheric integral wall-mounted solar water heater to solve the problems raised ...
