Cold water supplementing control system for solar water heater

Abstract

The invention discloses a cold water supplementing control system for a solar water heater. The cold water supplementing control system comprises a first cold water supplementing mode and a second cold water supplementing mode. The first cold water supplementing mode and the second cold water supplementing mode are controlled by a timing module, a heat collecting pipe heat collecting module, a water level detecting module and a water temperature detecting module. The first cold water supplementing mode and the second cold water supplementing mode are applied to carrying out cold water supplementing operation on the solar water heater on the conditions with abundant lighting or weak lighting. The first cold water supplementing mode and the second cold water supplementing mode control a cold water supplementing electromagnetic valve module to supplement cold water into a heat-preserving water tank. The cold water supplementing control system for the solar water heater is simple in structure, by means of the cold water supplementing module of the two modes, automatic switching can be achieved according to the specific environment conditions, moreover, the cold water in a pipeline can flow back into the solar water heater, and the system has the beneficial effects of fully utilizing solar energy, increasing heating speed and saving precious water energy.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a cooling water supplement control system for solar water heaters. Background technique [0002] With the improvement of people's environmental protection awareness and consumption level, solar water heaters have entered thousands of households as a convenient, environmentally friendly and safe product, and have been welcomed by the people. However, solar water heaters often encounter such problems when they are used. When using it, first turn on the faucet, let off the cold water left in the water pipe, until the hot water flows out, at this time a lot of water will be wasted, especially for the residents living on the ground floor, and the solar water heater does not distinguish between time periods. Cold water supplement control, whether the light is sufficient or the light is weak, the solar water heater adopts the same cold water supplement mode, so that due to e...

[0002] With the improvement of people's environmental protection awareness and consumption level, solar water heaters have entered thousands of households as a convenient, environmentally friendly and safe product, and have been welcomed by the people. However, solar water heaters often encounter such problems when they are used. When using it, first turn on the faucet, let off the cold water left in the water pipe, until the hot water flows out, at this time a lot of water will be wasted, especially for the residents living on the ground floor, and the solar water heater does not distinguish between time periods. Cold water supplement control, whether the light is sufficient or the light is weak, the solar water heater adopts the same cold water supplement mode, so that due to environmental changes, the light in summer is stronger than winter, and the light in daytime is stronger than night, which makes it necessary to use electric energy for heating The longer the time, the more power consumption, and the slower the heating speed, the inability to make full use of the sun's light will reduce the use efficiency.
