The air-energy water heater is indirect heating. Just like an air conditioner, turn it around. The cold air from the original air conditioner is evacuated outside and exchanges with the warm outside air. converted into water through the heat exchanger, thereby achieving The energy saving effect is that the thermal efficiency of ordinary domestic heat exchange heat pumps is already very high when it reaches 1:3. This is called air. energy water heater. It is either high tech as some say or ordinary air conditioning technology when the outside air temperature is high there is no heat exchange problem if the outside temperature is low and humidity is low. it will be difficult to exchange heat. Therefore, it is difficult to talk about energy saving during the coldest winters. In winter, only the amount of hot water is used, it is difficult to guarantee the stabilityity of the structure; the maintenance rate is high; market retention is low and it is difficult to guarantee maintenance of parts and other things in the future. In addition, the temperature generated by heat exchange is difficult to exceed 55 degrees, because the maximum protection temperature of the air conditioning compressor radiator is about 120 degrees. According to the principle of heat exchanger, the heat exchange temperature cannot be higher than. 55 degrees. If it is higher than this temperature, it will result in wasted work, which means there will be no energy saving. The compressor works for a long time under high load and its service life is also quite limited. The higher the temperature, the lower the heat exchange efficiency. Usually the most effective temperature for heat exchange is 25 to 28 degrees. Both the outside temperature and the water temperature are at thistemperature to achieve the best effect. For a long time. In terms of constant pool temperature and constant indoor hydration temperature, no one uses it for domestic water heating. That's about it, hope this can help you understand. Our company owns all types of water heaters and is a professional water heater engineer and service provider of all types. Guangzhou Yinli Mechanical and Electrical Equipment Engineering Co., Ltd.

Any energy saving equipment will only occur under certain conditions, so what method is used to address this in other cases? It only involves heating by the most traditional method, electric heating tubes.

Explanation of the principle of the air source heat pump

The principle of the air source water heater is as follows:

The air water heater uses Rankine circulationreverse, a device that transfers heat from low-temperature objects to high-temperature water through a medium. The heat pump device can cause the fluid (refrigerant) to change phase and become lower than the low temperature heat source, thereby spontaneously absorbing heat from the low temperature heat source.

The fluid after returning to the compressor is compressed into gas at high temperature (higher than water at high temperature) and high pressure, thus spontaneously generating heat to the high temperature heat source , carrying out the “transfer”; "heat from the low temperature heat source to the high temperature heat source.

Product features:

The heat pump of the Air-to-energy water heater works in exactly the same way as the air conditioner. It avoids the shortcomings of traditional solar products which cannot work pa.r rainy weather and night. When the outside temperature is 5 to 25°C, its coefficient of performance (the ratio between heating capacity and absorbed power) reaches 3 to 5.

The main devices of a heat pump are composed of an evaporator, a condenser, a compressor and an expansion valve. The working process is to continuously complete the evaporation of the working fluid (absorbing energy from the environment) → compressionThe process of the thermodynamic cycle → condensation (release of energy) → throttling → re-evaporation transfers heat from the environment to the heating object.

So that the temperature of the heated object reaches the use range. Since electricity is not directly involved in heating, it does not require a lot of electricity. The heat utilization rate of electric energy can reach 300%.

The principle of the air heat pump is explainedas follows:

The heat pump uses a refrigerant as the fluid, and the refrigerant has a low vaporization temperature. It can be sprayed at 40℃. There is therefore a temperature difference between it and the outside temperature and it vaporizes. gas at high temperature and high pressure. After exchanging heat with water through the heat exchanger, the expansion valve releases pressure and returns to the liquefied state at low temperature and low pressure through the continuous circulation of refrigerant and gas. heat exchange with water, the water in the water tank is heated.

Does a heat pump require electricity?

Electricity must be used. The main use of electricity is in the compressor to compress the refrigerant and in the fan to absorb heat from the air. It does not generate heat by direct heating, therefore. it uses much less'electricity.

What are the characteristics of a heat pump?

1. It is not affected by the environment and can be used all year round.

2. The energy saving effect is outstanding and the payback period is short.

3. Environmentally friendly products without any pollution.

4. Long life and low operating costs.

5. Safe operation and no operation.

Are heat pumps solar powered?

In terms of working principle, it does not belong to traditional solar energy. Heat pumps are very different from conventional solar energy. Conventional solar energy uses water as the fluid and must rely on direct sunlight or radiation to achieve the heating effect. Heat pumps use a refrigerant to absorb heat energy and energysolar radiation in the air and compress it. Thanks to a compressor. After heating, it exchanges heat with water to achieve the heating effect. Therefore, the principle of heat pump and air conditioner is the same.
