Commercial water heaters are widely used in hotels, railway stations, airports, hospitals and other public places, using electric energy or chemical energy to convert into heat energy. They have the advantages of safety, rapidity, low noise and no environmental pollution, and their supply is unlimited at any time. The capacity ranges from 2 liters to 200 liters, and the power ranges from 600 watts to 22 kilowatts.
2. Classification of commercial water boilers:
Traditional floating ball valve type: the water heater with the longest market, the oldest technology and the highest market share is gradually being eliminated.
Instant opening: it emphasizes instant burning and instant drinking, which has a good power saving effect, but it is not suitable for places with large continuous water consumption.
Boiling type: avoid the boiling water heater generated by yin and yang water, and do not knock or collide when cleaning scale.
Step-by-step: an energy-saving hot water device, which heats the water gradually from the bottom until the water boils.
3, commercial water boiler terminology:
3. 1, the principle, advantages and disadvantages of traditional floating ball valve water heater
This product has a history of several decades, and its structure is simple and its price is cheap. Using floating ball control and water storage heating, there is generally only one hot and cold water mixing tank, and the temperature indication is often a vague traffic light concept, which brings some people doubts about whether the water is boiled, and the heat preservation performance is average, and the power consumption is not energy-saving. Because water is often heated repeatedly, it has certain health risks and is gradually fading out of the market.
3.2. The principle, advantages and disadvantages of boiling water boiler
This kind of product often has three water tanks: cold water tank, open water tank and water storage tank. The cold water tank and the water storage tank for supplying boiled water do not communicate with each other, which eliminates the yin and yang water, and the raw and cooked water are completely separated and boiled only once, making it healthier to drink. Generally, high-power and low-power double heating pipes are used, with high-power heating (in the open water tank) and low-power heat preservation (in the water storage tank, the heat preservation temperature is about 90 degrees). The two pipes will not work at the same time, which can not only ensure the heating speed, but also save electricity during heat preservation.
Boiling water boiler is the most mainstream model for supplying pure 100 degree boiling water on the market, and it is used by most universities and hospitals in China. However, due to the high water temperature and high maintenance requirements in large-scale areas, attention should be paid to avoiding collision during maintenance.
3.3. Principle, characteristics and advantages of step-by-step water heater
Using microcomputer automatic control, cold water is replenished layer by layer from the bottom and heated layer by layer, and water intake, water replenishment and heating are carried out at the same time, which completely eliminates the phenomenon that raw water and boiled water are mixed together in ordinary water boilers. The walking-step water heater relies on electrodes to measure temperature, and the temperature control is accurate, and the outlet temperature is constant at 96-99 degrees; Electronic leakage protection alarm function, electronic temperature control, water-free dry burning prevention, overflow prevention and water leakage prevention function.
3.4, electromagnetic water boiler principle characteristics
Using high-frequency inverter electromagnetic induction heating technology, electric energy is converted into magnetic energy, and then into heat energy to heat water. This heating method overcomes the shortcomings of low efficiency of traditional electric heaters, but this kind of products are expensive, the daily maintenance cost is high, and the application is not very extensive.
