How should air energy water heaters survive the winter ?

1. Pipeline insulation.

Air energy water heater users know that when the ambient temperature is low, the water temperature of the air energy water heater drops very quickly, which is mainly because the water heater pipes and return pipes are not well insulated. In the insulation measures of pipelines, the small diameter of the pipe is generally insulated with thermal insulation cotton, and the large pipe is insulated with polyurethane foam.

2. Keep the power on.

In winter, the water temperature of the air energy water heater drops a bit quickly, and if the power is still off, it may cause frost. Because in winter, it is important to keep the air energy water heater energized, so that the air energy water heater not only does not cause frost due to low temperatures, but also ensures that hot water is available 24 hours a day.

3. Precautions for shutdown.

In the north, during the Spring Festival, the weather may still be very cold, but it can't stop people from wanting to go out to travel, but at this time, the air energy water heater at home needs to be shut down for a long time, and users should put all the water in the pipeline to prevent the pipeline from freezing due to the drop in temperature, and when it runs again, there is a comprehensive inspection of the system.

Fourth, icing treatment.

When you find that the air energy water heater pipe is frozen but has not yet cracked, do not directly knock on the pipe and splash hot water, but wait for the ice to melt naturally.

1. For users in the north, the air energy water heater is recommended to be installed indoors, and the drainage facilities or floor drain must be done during installation to prevent the condensate of the air energy water heater from being discharged, resulting in indoor floor water.

2. In cold areas, if the user does not use the air energy water heater for a long time, he needs to turn off the power and empty the water in the pipe to prevent the pipe from freezing. During operation, please do a full check of the system before turning it on.

3. Users can choose the start-up running time according to the local temperature change to reduce power consumption. Generally speaking, in winter, the temperature is higher between 13 and 15 noon, when the air energy water heater is started to heat, which can shorten the heating time and reduce electricity consumption.

4. Usually the water temperature for bathing in winter is 42, at this time it is recommended to set the target water temperature of the air-conditioned water heater to 55, which can not only ensure the comfort of hot water, but also meet the demand for hot water. When the water consumption in the home increases, it is necessary to set the target temperature of hot water higher, so as to fully meet the needs of the water heater.

The air energy water heater can be used normally in the northern winter, the working temperature range of the air energy water heater is -5 °C-45 °C, and the compressor is easy to break below -5 °C, which is not conducive to the production of hot water.

There is heating in the northern region, and the indoor temperature is generally not lower than 18 °C, and the machine installed indoors can be operated, so consumers in the northern region do not have to worry about not being able to use air energy water heaters in winter.

The air source heat pump water heater transports the heat in the air to the water through the refrigerant, the traditional electric water heater and gas water heater obtain heat energy by consuming gas and electric energy, and the air energy water heater achieves the purpose of heating water by absorbing the heat in the air, and can absorb about three times the heat energy to heat the water in the case of consuming the same electric energy.

Summary. As long as you can ensure that the water in the tank and water lines does not freeze, you don't need to empty it.

If the air energy water heater uses a pressure water tank, if it is not used for a period of time and the power is off, it is more conducive to the corrosion prevention of the metal liner of the water tank if the water in the tank is not discharged.

If the water in the tank is emptied frequently, it will cause the oxidation and corrosion of the metal liner of the tank to be aggravated.

Air energy water heater does not need to release water in winter?

As long as you can ensure that the water in the tank and water lines does not freeze, you don't need to empty it.

If the air energy water heater uses a pressure water tank, it is more conducive to the anti-corrosion of the metal liner of the water tank if the water in the tank is discharged without making the air standby and the power is cut off for a period of time.

If the water in the tank is emptied frequently, it will cause the oxidation and corrosion of the metal liner of the tank to be aggravated.

Air energy water heaters can be used for heating in winter, as long as the fan coil unit device is added, it can be realized.

Air energy water heaters.

Air energy heat pump has three functions hot water, refrigeration and heating, the so-called air energy water heater may be a general word for some people, because air energy heat pump is mainly used in the south for water heater equipment, but now the national policy guidance is air energy heat pump heating, so air energy heat pump can be heated, Shanxi Benoy Solar Energy Technology Co., Ltd. is a high-tech company with solar energy products as the leader and solar energy development as the main body.

No. To put it bluntly, an air water heater is an air conditioner, an outdoor unit, and a water tank. The heat in the air is exchanged with water by passing it through a refrigerant (note that it is not the usual freon but CO2).

The single use of air energy for heating is not very suitable, and the energy consumption cost is high, so it is feasible to combine solar energy with low-temperature air energy for heating from the perspective of energy saving.

Air energy water heaters, also known as "air source heat pump water heaters". The "air energy water heater" absorbs the low-temperature heat in the air, vaporizes the fluorine medium, and then heats up and pressurizes through the compressor compression, and then converts the water into water for heating through the heat exchanger, and the compressed high-temperature heat energy is used to heat the water temperature. Air energy water heater has the characteristics of high efficiency and energy saving, making the same amount of hot water, which is 4-6 times that of electric water heater, and its average annual thermal efficiency ratio is 4 times that of electric heating, and the utilization energy efficiency is high.

It is definitely less economical than gas and electric water heaters, as for how much it is saved. Can you add what degrees of temperature are the coldest times of winter in your area? I'll give you an estimate.

Look at the outside temperature.

The higher the temperature, the more energy is saved-thermal efficiency.

The higher the bai.

The lower the temperature, the more electricity is consumed – the lower the thermal efficiency.

The thermal efficiency of air DAO energy depends first on the design of air energy itself, such as the structure, material and quality of sheet metal, heat exchange and other components.

For the same part of air energy, the external condition of the deheating efficiency is the temperature.

At 25 --15, the thermal efficiency of air energy is the same as that of electric heating, and will not exceed 1

At 15---10, the thermal efficiency is in between.

10--0, the thermal efficiency is between.

At 0-10 degrees Celsius, the thermal efficiency is about between.

If the temperature reaches 25 degrees Celsius, then the thermal efficiency can definitely reach more than 3.

In other words, one kilowatt-hour of electricity produces 3 kilowatt-hours of heat.

I also want to know that this is also what the developer who bought the house.

Air energy heat pump water heaters first began to rise in the south. Because there is a large demand for hot water in the southern region, whether it is a commercial or domestic water heater, many users or manufacturers have a greater interest in this new generation of hot water equipment, and the good experience of many projects also proves that the air energy water heater is indeed a good product.

However, many people think that air energy heat pump is indeed a very good product in the south, but it is just an ornament in the north, if this sentence was put ten years ago it made sense. Because the air energy equipment ten years ago was not so mature in technology, it was easy to attenuate the heating efficiency when dealing with low temperature environments. However, in recent years, as more and more companies have begun to focus on the research and development of air energy products, the air energy industry has also ushered in changes.

Take it"Coal-to-electricity"16 years is"Coal-to-electricity"The Great Year. According to the statistics of relevant departments, Beijing"Coal-to-electricity"The share of air energy rose from 10% in 15 years to 70-80% in 16 years. In rural areas of Beijing alone, 16 years of heat pump heating equipment has completed the installation of 10,000 units.

The division of north and south is generally bounded by the Huai River, and Beijing obviously belongs to the northern region north of the Huai River, and the good experience of air energy heat pumps used in Beijing makes it"Air energy heat pumps are not available in the north"The rumors are self-defeating.

It is true that air energy can be used in the north now, but whether it is good or not is also a key point that we need to pay attention to. At present, the two most commonly used technologies of air energy heat pumps are frequency conversion technology and jet enthalpy increase technology, which is also the basis for air energy heat pumps to have a good use experience in the north. Air energy inverter technology is to add an inverter to the air energy water heater, and use the inverter function of the inverter to change the working frequency of the air energy equipment compressor and improve the heating capacity of the air energy heat pump, so that the air energy heat pump can also run freely in a low temperature environment.

Another jet enthalpy enhancement technology is to install a jet enthalpy booster compressor inside the air energy heat pump, and the steam generated by the evaporator is passed into the compressor, so that the heating process is divided into two stages, and the single-stage compression becomes"Quasi-secondary compression"Increase the discharge pressure of the compressor, increase the amount of refrigerant going to the heat exchanger, and improve the heating efficiency. The rational use of these two technologies has made air energy heat pumps begin to occupy a place in the north.

Of course, the air energy water heater can be used in the winter in the north, and the air energy water heater is based on the heat pump for heating and water supply, as long as you choose a product suitable for the ambient temperature, you can ensure the normal use of the winter. In addition, the effluent temperature is particularly stable and very energy-efficient.

The general air can be used in all seasons in the south, because the temperature in the south is relatively high in winter, and the technical requirements for air energy are not high. However, the general air energy can not be used in the winter in the north, because the temperature in the north is particularly low in winter, so the air energy cannot work at all, and it must be supplemented by electric heating to survive the winter. And there is no auxiliary electric heating, so the air in the northern winter can be used by a few brands.

No problem, the latest technology has allowed the air source heat pump to function properly in a -35 environment.

The working temperature range of ultra-low temperature air energy water heater is -25 °C-45 °C, and the compressor is easy to break below -25 °C, which is not conducive to making hot water.

Yes, it can be used in all regions of our country, and ultra-low temperature air energy water heaters are generally used in the north, which can be used at minus 35 degrees.

But the lower the ambient temperature, the lower the energy efficiency of the air energy water heater, if you use it in the north, it is best to find a big brand with many models in the northern region, such as Guangzhou Fenni, machine quality, energy efficiency, pre-sales and after-sales service will be much better.

I don't know how long the manufacturer warranty of the air energy water heater you bought? There is no need to deliberately maintain, just normal use is no problem, the above answer is not only maintenance, but also there is a warranty problem, I personally think that the above is the air energy company or the first business to consider the problem, and the customer only needs to consider how to use the convenience and comfort.

If the air energy water heater is not used in winter, it is recommended to take the following maintenance measures:

1. Empty the water inside the water tank and the main engine: the steps to empty the water in the water tank are as follows: There is an overpressure protection device or water discharge valve under the water heater;

The water can be released by closing the water inlet valve, opening the protection valve (water discharge valve), and opening the water outlet (hot water faucet, sprinkler head, etc.) at the same time.

Precautions: When emptying the water in the water tank, remember to close the protection valve and the water outlet in time to prevent water leakage when the water is loaded next time.

2. After the water is emptied, turn off the power supply and socket of the main engine of the air energy water heater.
