Temperature-adjustable solar hot water supply system

Abstract

The invention discloses a temperature-adjustable solar hot water supply system which comprises a solar water heater, a water storage tank, a controller and a heat preservation case device. The solar water heater is composed of a water tank and solar heat collecting pipes mounted on the water tank. An inlet of the water tank is connected with a cold water pipe, and an outlet of the water tank is communicated with an inlet of the heat preservation case device through a hot water pipe A. An outlet of the heat preservation case device is communicated with the water storage tank through a hot water pipe B, and the cold water pipe is provided with an electromagnetic valve which is connected with the controller through a wire. A water outlet in the water storage tank is communicated with the cold water pipe through a cold-hot water communicating pipe, a cold water control valve is arranged on the cold-hot water communicating pipe, a hot water control valve is arranged on the hot water pipe B, and a thermometer is further arranged on the top of the water storage tank. According to the temperature-adjustable solar hot water supply system, the water temperature can be adjusted conveniently and rapidly and can be adjusted according to needs, water resource waste caused by overhigh or ultralow water temperature is avoided, electric energy consumed by hot water boiling can be saved, and the purpose of saving energy is achieved.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a temperature-adjustable solar hot water supply system. Background technique [0002] Solar water heaters are popular among thousands of households because of their energy saving, environmental protection, stable performance and low maintenance workload. However, due to the heat dissipation of the outlet pipe of the solar water heater, a small amount of water is always flowing out of cold water. Cold water, which not only delays time but also causes a lot of waste of water resources, especially in winter and the problem of low-rise users is even more serious. Another defect of the currently used solar water heaters is that when it rains on cloudy days or when the water consumption for bathing is large, the hot water cannot meet the supply, especially in winter when the light time is short, resulting in a serious shortage of hot water in the solar water h...

Problems solved by technology

However, when the system is in use, the temperature of the mixed hot and cold water in the incubator can only be sensed by the human body, and the temperature of the mixed water in the incubator cannot be seen intuitively, which makes it difficult to adjust the water temperature
