Solar hot water heat exchanger unit

Abstract

The invention discloses a solar hot water heat exchanger unit. The solar hot water heat exchanger unit mainly consists of a solar heat collector, a heat exchange hot water storage tank, a solar circulating pump, a variable-frequency hot water pump, a silver ion generator, a flow adjusting valve, an auxiliary heating hot water boiler and a control cabinet, wherein outlet water of the heat exchange hot water storage tank is connected with a heat supply water outlet pipe; the other end of the heat supply water outlet pipe is connected with the auxiliary heating hot water boiler; the variable-frequency hot water pump is mounted on the heat supply water outlet pipe; the silver ion generator is arranged on the heat supply water outlet pipe behind the variable-frequency hot water pump; a heat exchanger is arranged in the auxiliary heating hot water boiler; the heat supply water outlet pipe is connected with an inlet of the heat exchanger; an outlet of the heat exchanger is connected with the hot water supply pipe; a bypass pipe is arranged between the heat supply water outlet pipe and the hot water supply pipe bypassing the auxiliary heating hot water boiler; and the flow adjusting valve is mounted on the bypass pipe. The solar hot water heat exchanger unit has such advantages as energy conservation, safety, economy and intelligent control, and has the beneficial effects of complete protection functions, strong adaptability, long service life and convenience for use.

Description

technical field [0001] The invention relates to the technical field of solar heating, in particular to a solar hot water heat exchange unit. Background technique [0002] Solar energy has been widely used in many fields due to its advantages of abundant resources, in-situ utilization, cleanness and regeneration. Solar hot water is an application field of solar energy achievements. It has quickly won the favor of consumers due to its advantages of environmental protection, safety, energy saving, and sanitation. Solar water heating mainly takes solar water heaters as a major industry, but solar water heaters are based on the family as a unit, use scattered, installation trouble and not conducive to layout, especially for residents of dense residential buildings, it is difficult to install and use. Large-scale and large-scale solar centralized hot water supply systems can better solve the situation of high-flow hot water use by residents of dense residential buildings, hotels,...

AI Technical Summary

Problems solved by technology

Since the boiler opening of the hot water atmospheric boiler is connected to the atmosphere, the water in the boiler directly participates in the hot water circulation and heating, which is likely to cause boiler water loss, oxidation corrosion, backflow failure, etc., and will also cause pressure loss in the hot water circulation, so it cannot be used Hot water circulation pressure increases power consumption
