Advantages of air source water heater

Water heaters are also one of the necessary household appliances in winter; at the same time, energy saving has now become a major reference indicator for consumers when purchasing home appliances. As an energy-saving upstart in the field of water heaters, “air energy water heaters” must have been heard by everyone. In the propaganda of many manufacturers, “air energy water heaters” claim that one degree of electricity can be used for four degrees, and the energy saving efficiency is as high as 75%.

Principle

The air energy water heater uses a small amount of electricity to drive the compressor to work, transfer the heat in the air to the water, make the water hot, and reach the water temperature that can be bathed.

The air-conditioning water heater is a multi-functional air-energy water heater that can provide constant temperature hot water for the whole family and provide air-conditioning for the kitchen for free.

When the machine is working, under the suction of the fan, the ordinary outdoor air enters the top inner cavity from the air inlet and flows through the heat exchanger.

At this time, the energy in the air is absorbed by the heat exchanger and transferred to the heat preservation water tank to heat the water; The temperature of the air that loses energy is lowered and becomes cold air blown out from the fan, which can be used for kitchen cooling in summer.

The hot water in the thermal water tank can be used for multiple purposes such as bathing and laundry for the whole family.

What kind of energy does the air energy water heater rely on to heat water? Is it really “burning air”? In fact, an air-energy water heater does not “burn air”, but it does use air to heat, and it uses the heat energy in the air.

In fact, you can regard an air-energy water heater as an air conditioner, because its principle is indeed similar to that of an air conditioner. It uses fluorine media and compressors to transfer heat, but the air conditioner transports heat away from the air. To achieve cooling, the air-energy water heater collects the heat in the air and uses it for hot water.

Work program

Four major parts of refrigeration: evaporator, compressor, condenser, and throttling device.
Stable three parts: liquid storage tank (compressor), expansion valve (capillary), dry filter (filter water and impurities)
A big piece of defrosting: four-way valve

When the heat pump is working, the working fluid can absorb the energy Q2 stored in the environmental medium in the evaporator; while starting the system needs to consume energy, that is, the compressor consumes electricity Q1; at the same time, the working fluid releases heat Q3 to the high-temperature medium in the condenser; compression After the machine input work to start the system, the mechanical kinetic energy becomes heat energy.

Therefore, the energy delivered by the heat pump is the sum of the work Q2 done by the compressor and the heat Q1 absorbed by the heat pump from the environment; input a Q2, get Q1+Q2, and break through the bottleneck of the traditional single different energy conversion that cannot achieve 100% efficiency; adopt Heat pump technology is more energy efficient. Break through the traditional energy conversion theory to achieve high energy efficiency.

Therefore, ordinary air-energy water heaters have outdoor units like air conditioners. Of course, there are also integrated air-energy water heaters without outdoor units.

Advantage

The biggest advantage is no doubt that it saves electricity. How can an air-energy water heater use one degree of electricity as four degrees?

The main reason is that the electric energy consumed by the air-energy water heater is not directly used for heating, but is used to carry free heat energy in the air. Generally speaking, 1 kilowatt of electric energy can carry 3-4 kilowatts of heat, while ordinary electric water heaters, Even if calculated on the basis of 100% energy conversion rate, 1 kilowatt of electric energy can only produce 1 kilowatt of heat energy, so air energy water heaters can achieve several times lower energy consumption than traditional water heaters.

Secondly, convenience is also a highlight of air-energy water heaters. Because the amount of air is not affected by indoor and outdoor and sunny days, compared with solar water heaters, air-energy water heaters are very convenient. Whether installed indoors or outdoors and regardless of cloudy or sunny days, the temperature is above zero degrees Celsius. can use.

In addition, after a tank of water is used up, the air-energy water heater can make another tank of hot water in no more than one hour, which can be used by the family all day.

Safety is also an advantage of air-energy water heaters

Electric water heaters have potential safety hazards of electric leakage, and gas water heaters have the risk of gas poisoning. Compared with these two water heaters, air-energy water heaters exchange heat through media, avoiding direct contact between electric heating elements and water, thus solving the problem of electric water heaters. Existing leakage hazards.

Secondly, because the raw material is air, the possibility of gas explosion or gas poisoning of gas water heaters is also ruled out, making people more comfortable and worry-free to use. The electric energy of the air-energy water heater is mainly used to transfer heat and does not directly act on the water so that electricity and water are separated very well, and there is no need to worry about the risk of leakage.

Finally, it is worry-free. A suitable air-source water heater can be used for as long as 15 to 20 years. The high life can not only reduce the cost and trouble of people replacing the water heater.
