Embodiment 1

[0064] The system is placed in the "working state", the water temperature sensor of the collector, the water temperature sensor of the water storage tank, the water temperature sensor of the drinking water tank, the liquid level sensor of the water storage tank, and the water temperature of the water storage tank Detect, detect the water level of the corresponding water storage tank and drinking water tank, and start timing the working time of the system to check whether the system is working.

[0065] A. When the water temperature at the water outlet 27 of the heat collector reaches the upper water outlet temperature of 65°C, the water supply solenoid valve D1 is opened, and the cold water is pushed into the heat collector through the water supply pipe 32 and the water inlet at the lower part of the heat collector 26, and the hot water The water storage tank 17 is pushed into the water storage tank 17 from the water outlet 27 on the upper part of the heat collector. When the w...

Embodiment 2

[0072] The upper limit temperature of the outlet water is 70°C, and the lower limit temperature of the outlet water is 55°C.

[0073] In D, when the liquid level Y2 of the drinking water tank 12 is lower than the minimum water level 9' of the drinking water tank and / or the water temperature of the drinking water tank 12 is lower than the minimum water temperature of the drinking water tank 45°C, the electric heater 10 is turned on; when the water temperature T3 of the drinking water tank is low When the minimum water temperature of the drinking water tank is 45°C, the solenoid valve D7 of the drinking water tank is opened, and when T3 reaches the maximum water temperature of the drinking water tank of 48°C, the solenoid valve D7 of the drinking water tank is closed, and the solenoid valve D6 of the mixing water is opened, and cold water is added to the drinking water tank; when T3 When the water temperature of the drinking water tank is lower than the minimum water temperature ...

Embodiment 3

[0076] The upper limit temperature of the outlet water is 75°C, the lower limit temperature of the outlet water is 60°C, and the rest are the same as in Example 1.

Abstract

The invention provides a solar potable water preparation system and a method for preparing potable water by using the solar potable water preparation system, which aims to overcome the defects that when hot water is prepared by a solar water heater in the prior art, water scales and deposits are easily formed, nitrite is produced, and the potable water standard cannot be achieved. The solar potable water preparation system comprises a heat gathering system, a water storage system, a water system and an electric control system, wherein the water outlet temperature of the heat gathering system, the water level of the water storage system, and the water temperature and water level of the water system are controlled by the electric control system. By using the solar potable water preparation system and the method for preparing the potable water, the production of the nitrite can be prevented or effectively reduced, thereby obtaining the potable water which achieves the potable water standard.

Description

technical field [0001] The invention relates to a solar water heating system and a method for preparing edible hot water using the system. Background technique [0002] Solar energy has been widely used in bathing, heating and so on. However, due to the long-term and continuous heating of the water in the collector, the water will deposit and produce a large amount of nitrate, so the water directly heated by solar energy cannot meet the drinking water standard and cannot be drunk. At present, in order to overcome the above-mentioned shortcomings, those skilled in the art adopt the method of heat exchange and use solar energy to prepare drinking water. The preparation of drinking water by heat exchange has the following disadvantages: the system is complicated, the cost is high, and the efficiency is lower than that of direct heating. For example, the patent name is "solar drinking water system", the patent number is 200920102892.0, and the authorized announcement number is ...
