Description

A solar intelligent temperature control valve

technical field

The utility model relates to an intelligent temperature control valve, in particular to a solar energy intelligent temperature control valve.

Background technique

A solar water heater is a renewable energy device that uses the radiant energy of sunlight to heat water for use. In today's shortage of resources, the utilization rate of solar water heaters is increasing at a steady rate every year. According to the survey, by 2009, solar water heaters have occupied 57.2% of the entire water heater market. However, ordinary solar water supply systems cannot efficiently utilize the cold water in the pipeline between the water device and the solar water storage device, resulting in a serious waste of water resources. It is necessary to remove the cold water in the solar water supply pipe for normal use; some solar energy is also equipped with a manual Water supply and discharge system; the temperature of discharge water cannot be controlled.

The inability to automatically control the water discharge temperature is one of the disadvantages of solar water heaters. For users, the cold water in the solar water supply pipe needs to be drained before using hot water, and the temperature of hot water needs to be adjusted manually, which not only causes waste of water resources but also Embodies the shortcoming that the solar water heater cannot be intelligentized. For some solar water heaters that require manual water supply and discharge, this shortcoming is more obvious.

Although the gas water heaters on the market have solved this problem, the gas water heaters will emit toxic gases and pollute the environment due to insufficient combustion during use, causing greater waste of resources and easily causing safety accidents; the starting water pressure is high, and some Users who live on high floors cannot start without a booster pump. It is inconvenient to install, and it is necessary to drill holes in the wall and arrange gas fans, etc.; the shape of the burner, the size of the nozzle, and the cross-sectional area of the gas channel are different for different gases. In summary, gas water heaters have the disadvantages of polluting the environment, producing toxic gases, causing safety accidents, wasting resources, and high starting water pressure.

The electric water heater solves the problem of wasting water resources, but causes a large loss of electric energy, and is bulky, takes up a lot of indoor space, is prone to scale formation, and is difficult to clean scale, which affects the life of the heater.
