Abstract

The invention relates to a flat plate solar water heater with circulation of a frequency conversion working substance. The flat plate solar water heater comprises a microcomputer controller, a frequency conversion module, a small solar panel, a hot water tank, a flat plate solar heat collector, a working substance circulating pump and a connecting pipeline, and is characterized in that an output interface of the computer controller of the flat plate solar water heater is connected with an input interface of the frequency conservation module, an analog quantity input interface of the computer controller is connected with a voltage output interface of the small solar panel, and the output interface of the frequency conversion module is connected with a motor of the working substance circulating pump. Compared with the conventional flat plate solar water heater driving the circulating pump by fixed-frequency alternating current, the flat plate solar water heater can improve the yield of hot water of the flat plate solar heat collector and reduce the operation energy consumption of the working substance circulating pump.

Description

technical field [0001] The invention relates to a flat solar water heater with variable frequency working medium circulation, in particular to a flat solar water heater which uses a small solar panel to control the frequency conversion frequency of a working medium circulation pump. Background technique [0002] A flat-panel solar water heater consisting of a solar collector plate, a hot water tank with a working medium heat exchanger, a working medium circulation pump, a circulation pipeline, and a computer controller. Usually, the computer controller controls the working medium circulation pump according to the set temperature difference. Runs at a fixed frequency of 50Hz. The start and stop of the working fluid circulation pump is only determined by the temperature difference between the solar collector plate and the water tank, and has no direct connection with the strength of the solar energy, so the circulating flow of the working medium is not synchronized with the st...
