Abstract

The present invention discloses a double-pipe type solar water-heater. Its waterway is divided into upper and lower two water pipes, on the upper water pipe a water-supplying electromagnetic valve and a temperature-measuring probe are mounted, the electroheater in the water tank is controlled by temperature control regulation instrument, on the lower water pipe are successively mounted a pipe electroheater, booster pump and hot water valve, between upper water pipe and lower water pipe a circulation pipeline is connected so as to form a loop, the circulation electromagnetic valve is mounted on the circulation pipeline. Its electric circuit portion includes temperature-measuring probe, temperature sensor, temperature control regulation instrument, level sensor, electromagnetic valve, booster pump and automatic control instrument, etc. Besides, said invention also provides its working principle and its concrete operation method.

Description

1. Technical field: [0001] The invention relates to a water heater, in particular to a double-tube instant-on solar water heater. 2. Background technology: [0002] Solar water heaters have been widely used in many fields at present. Solar water heaters in the prior art generally include water tanks, vacuum heat collecting pipes, water pipes and valves shared by upper and lower water. The indoor water point is connected, and the valve is installed in the corresponding position of the water pipe. Some high-end solar water heaters are also equipped with electric heaters in the water tank in order to be used in winter or rainy days. However, these solar water heaters have the following problems due to the influence of heat collecting area, illumination, shared single pipe for upper and lower water, installation location and climatic conditions: [0003] 1. The temperature of the produced water is uneven in summer and winter, the temperature of the produced water in summer is t...
