Air energy water heater, also called "air source heat pump water heater". The "air-energy water heater" absorbs the low-temperature heat in the air, is vaporized by the fluorine medium, then pressurized by the compressor to increase the temperature, and then converted to the water for heating by the heat exchanger, and the compressed high-temperature heat is used to heat the water temperature.

The air energy water heater has the characteristics of high efficiency and energy saving. It produces the same amount of hot water, which is 4-6 times that of ordinary electric water heaters. Its annual average heat efficiency ratio is 4 times that of electric heating, and its energy efficiency is high.

The new product overcomes the shortcomings of solar water heaters relying on sunlight for heat and inconvenient installation. Since the air-energy water heater works by exchanging heat through the medium, it does not require the electric heating element to directly contact the water, avoiding the risk of electric water heater leakage, and preventing the possible explosion and poisoning of the gas water heater, and more effectively controlling the gas. Air pollution caused by exhaust gas from water heaters.

The air-energy water heater does not require sunlight, so it can be placed at home or outdoors. After the water stored in the solar water heater is used up, it is difficult to produce hot water immediately. If electric heating takes a long time, and the air can heat water above minus 20 degrees Celsius, it can run under pressure 24 hours a day. In this way, even after using a tank of water, the air-energy water heater will generate another tank of hot water in about an hour or even less.

At the same time, it can also fundamentally eliminate safety hazards such as electric water heater leakage, dry burning, and harmful gas generated when gas water heaters are used. Air source heat pump water heaters, as the name suggests, transfer heat from the air to water through refrigerants. Traditional electric water heaters and gas water heaters Heat energy is obtained by consuming gas and electric energy, while air energy water heaters achieve the purpose of heating water by absorbing heat in the air. Under the same electric energy consumption, it can absorb heat energy equivalent to about three times the electric energy to heat water.

Work program

Four major parts of refrigeration: evaporator, compressor, condenser and throttling device.

Three stable parts: liquid storage tank (compressor), expansion valve (capillary tube), filter drier (filtering moisture and impurities)

One big piece of defrosting: four-way valve

Break through the traditional energy conversion theory and achieve high energy efficiency:

When the heat pump is working, the working fluid can absorb the energy QA stored in the environment medium in the evaporator;

The start-up system needs to consume energy, that is, the compressor consumes QB;

At the same time, the heat QC released by the working fluid to the high-temperature medium in the condenser;

After the compressor input work starts the system, it changes from mechanical kinetic energy to thermal energy. Therefore, the energy delivered by the heat pump is the sum of the work QB done by the compressor and the heat QA absorbed by the heat pump from the environment; input a QB to get QB+QA, breaking through the traditional bottleneck that the conversion between single different energy cannot achieve 100% efficiency; Heat pump technology has a higher energy efficiency ratio.

working principle

The air-energy water heater works according to the principle of "reverse Carnot". Specifically, the "outdoor unit" acts as a heat exchanger to absorb heat from outdoor air, heats and evaporates the low-boiling point working medium (refrigerant), and the refrigerant vapor is compressed The machine compresses and heats up and enters the water tank, releases the heat into the water and condenses and liquefies, and then throttles, reduces pressure and cools back to the outdoor heat exchanger to enter the next cycle. To put it simply, it absorbs the heat in the air to heat the water, and the heat-absorbed air can also be used in the kitchen to solve the problem of sultry heat.

Heat is produced by the working principle of heat pump, which is the opposite of air-conditioning refrigeration-the national refrigeration standard is 1000 watts and electric refrigeration is 2800 watts. According to the principle of heat balance, at least 2800 watts of heat are generated at the same time, plus the input of 1000 watts of electricity, the actual heat generated is 3000-4000 watts, and the heat is transferred to the heat preservation water tank, and its power consumption is only a quarter of the electric water heater. One (Even if the thermal efficiency of an electric water heater is 100%, it only has 1000 watts of heat when the input is 1000 electricity).

Air-energy water heaters do not require sunlight, so they can be placed at home or outdoors. After the water stored in the solar water heater is used up, it is difficult to produce hot water immediately. If electric heating takes a long time, the air-energy water heater can operate under pressure 24 hours a day, as long as there is air and the temperature is above zero degrees Celsius.

In this way, even after using one tank of water, the air-energy water heater will produce another tank of hot water in about an hour. At the same time, it can also fundamentally eliminate the safety hazards such as electric water heater leakage, dry burning, and harmful gas generated when gas water heaters are used, and overcome the shortcomings of solar water heaters that cannot be used in rainy days and inconvenient installation. It has high safety, high energy saving, and long life. , No emission of poisonous gas and many other advantages. The life of air energy water heaters can generally reach 15 to 20 years.
