School solar water hot water use water and solar water heating project safety measures
For the school of solar hot water use and solar water heating project safety measures, kindergartens, nursery, generally use 24h water, hot water pressurized, constant temperature water supply, that is, that is hot.
The school dormitory generally use regular water, hot water pressurized, constant temperature water supply.
School of solar energy project hot water is divided into the following points.
Solar hot water system daily storage of hot water is limited, not a steady stream of hot water; due to the neglect of the school management, many schools after the students forget to close the shower bath situation, resulting in a great waste of hot water, hot water is not enough ; To ensure that students bath, reduce the waste of hot water, schools need to meet the solar energy system to increase water-saving measures, constant temperature water supply mode of several water-saving way:
1. Low-pressure water supply Water-saving way: branch pipe to increase the pressure reducing valve, so that hot water shower pressure to maintain 0.05WPa ~ 0.07WPa, slow down the flow rate, effectively save the flow, to achieve the purpose of saving hot water.
2. Water card water intake way: to the general shower to increase the credit card water intake equipment, set the credit card water for each 10L, students bath once, credit card 3 to 4 times, to achieve the purpose of saving hot water.
3. Touch-type shower water-saving way: to the general shower to increase the touch switch, finger touch the shower open, and then touch the shower closed, such as touch the opening after the shower nozzle forget to close, shower nozzle delay 60s closed (adjustable ), Effectively save traffic, to achieve the purpose of saving hot water.
4. Infrared shower water-saving way: the installation location from the ground 1m, infrared sensor area is 1m Iraq 0.5m, people standing in the sensor area 3s (adjustable), shower open, people leave the sensor area after 5s (adjustable) , The shower automatically shut down; effectively save the flow, to achieve the purpose of saving hot water.
5. Pedal shower water-saving way: one foot pedal switch, shower open, foot off the foot switch, shower automatically shut down; effectively save traffic, to achieve the purpose of saving hot water.
For the school solar hot water project winter and summer vacation idle maintenance
First, for the school during the winter vacation idle maintenance measures
Collectors and water tanks during the winter vacation all the power outage, pay attention to the pump water to be empty clean. 3 days before the end of winter vacation start, rinse, test run.
Second, for the school solar hot water during the summer vacation maintenance measures
Due to the high amount of solar radiation in summer, in order to prevent the heat collector caused by heat damage, should take the collector cover measures; the rest of the measures above.
The above points, is the school solar hot water engineering design must take into account the place. Only in the design of these issues are taken into account in order to ensure that the solar hot water project to achieve all the hot water supply school.
