Why do you have to choose inverter for air energy heat pumps?

Variable frequency air energy is relatively energy-saving.

Especially for household air energy, the indoor load will change, so the compressor is required to be in variable load operation all the time, if it is a fixed-frequency compressor, it will start frequently, which will not only shorten the life of the compressor, but also consume electricity.

It will also have an impact on the power grid.

Inverter air energy is generated.

Why do air conditioners like to choose inverters?

Air can be inverted for the same reason as air conditioning.

<> Gemei Yue air energy heat pump inverter unit.

First of all, it depends on whether it is in the south or the north, the frequency conversion and fixed frequency in the south can be used, and the frequency conversion effect in the north is better.

(1) Variable frequency air energy is more energy-efficient than fixed frequency

The working frequency of the fixed-frequency air heat pump will not change, no matter whether the outdoor ambient temperature is high or low, it will operate at the same frequency, shut down when the set temperature is reached, and restart when it reaches the set temperature. Not only does this stop and start machine not save energy, but it consumes more electricity. The working frequency of inverter air energy will be adjusted according to the relevant parameters, and it will not stop after reaching the set temperature, but will maintain operation with the lowest consumption, so the energy saving effect is better.

(2) The service life of variable frequency air is longer than that of fixed frequency units

Fixed-frequency air energy will turn the machine on and off frequently, so the power consumption is greater. The frequent start-up and shutdown of the fixed-frequency unit will also shorten the service life of the air energy compressor, so the service life of the variable frequency air energy is longer than that of the fixed-frequency unit.

(3) Frequency conversion air can be more suitable for low temperature working conditions

Air energy heating is generally used in winter, due to the relatively low winter temperature in the north, the requirements for air energy heat pumps are higher, and the fixed frequency air can be used in ultra-low temperature environments, and there will be poor heating efficiency, or even no heating. The inverter air can work in real time to change the working frequency, and will run at full power when the heat required in extremely cold weather is not reached, accelerate the rise of temperature, and reduce the operating power when the set temperature is about to be reached, so as to achieve energy saving.

More energy efficient. Aoclair inverter air energy has achieved high capacity and high efficiency, increased energy efficiency by more than 30% compared with ordinary products, COP energy efficiency has reached the seasonal energy efficiency A+ standard, and has the advantages of rapid temperature rise, significant energy-saving effect, economical operation, and do not use more electric energy.

Wide voltage range. When the Auclair inverter air is started, the current is low, it will not impact the power grid, and it can reduce the interference to other electrical appliances in use in the room. The wide voltage of 120V-270V is applicable and completely solves the problem of affecting the work due to voltage instability.

The difference between air energy frequency conversion and fixed frequency: different choices, different principles. Advantages of air energy inverter: high efficiency and energy saving, long life, good stability, and strong low-temperature heating.

First, the choice is different:

The inverter air energy heat pump has more advantages in places lower than -5, and has good energy saving; Fixed-frequency air energy heat pump is economical and cost-effective to operate at a temperature above -5, which is better, or according to your own situation.

Second, the principle is different:

When the indoor temperature reaches the desired value, the air conditioner host runs at a constant speed that can accurately maintain this temperature, so as to achieve "non-stop operation", so as to ensure the stability of the ambient temperature.

A fixed-frequency air conditioner is a unit used to provide a space area with a treatment for changes in air temperature. The voltage of the national household power grid is 220 volts, 50 Hz, and the air conditioner that works under this condition is called a fixed-frequency air conditioner.

How it works. The refrigerant working fluid in the evaporator begins to evaporate at about minus 39 degrees Celsius, and at the same time absorbs heat and becomes a low-temperature and low-pressure gas; the low-temperature and low-pressure gas becomes a high-temperature and high-pressure gas after compression by the compressor; the high-temperature and high-pressure gas enters the heat exchanger to exchange heat with cold water; the working fluid after exothermy becomes a low-temperature and low-pressure liquid and enters the evaporator for the next cycle.

In this way, the process of producing hot water is realized in a continuous cycle. The heat pump can obtain more than 4 times the energy of electricity from the outside world by putting one kilowatt-hour of electricity when it is working, while the energy of one kilowatt-hour of electricity put into an ordinary electric water heater can only theoretically obtain the heat of one kilowatt-hour of electricity.

The difference between air energy frequency conversion and fixed frequencyAir energy frequency conversion can adjust the power of the unit according to the voltage frequency, and the fixed frequency can not be adjusted, no matter how large the voltage frequency is to work at the same frequency.

Advantages of air energy inverter

1. High efficiency and energy saving

Frequency conversion air can determine the operating frequency of the compressor and fan according to the amount of heat (cold) needed, so as to achieve reasonable use of energy, because the compressor will not be turned on frequently, the compressor will maintain a stable working state, so it will not consume more electrical energy. It can save more than 30% of the overall energy efficiency of COP compared with fixed-frequency air energy.

Second, long life and good stability

During the operation of the fixed-frequency air source heat pump, no matter how large the load of the main engine, the unit can only run at one frequency, and the voltage range can only be 220V, and it will stop when the temperature reaches the set temperature, and it will be restarted when the temperature drops to the range. In addition to consuming electricity, such frequent shutdowns and restarts also have an impact on the life of the compressor.

The voltage adaptation range of the variable frequency air source heat pump is 120V-270V, which solves the problem of affecting the work due to the instability of the voltage. And it can automatically adjust the number of revolutions of the compressor according to the change of ambient temperature, and the operation is more stable. Even when the temperature is reached, there is no downtime, but the operation is maintained with low energy consumption.

Therefore, in terms of service life and stability, the inverter air source heat pump is superior.

3. Strong heating at low temperature

At room temperature, the heating energy efficiency of fixed-frequency air source heat pump and inverter air energy is not much different, but the lower the temperature, the more obvious the difference.

Taking inverter air energy floor heating air conditioning as an example, at 15 -20 hours, the difference between inverter air energy and fixed-frequency air energy heating capacity is less than 10%, at minus 15, inverter air energy is about 60% higher than fixed-frequency air energy heating capacity, and when it reaches minus 25 degrees, this gap is increased to 80%.

Definition of frequency conversion and fixed frequency.

First of all, from a literal point of view, frequency conversion is a way that can change the operating frequency, and it is called frequency conversion that can realize AC control by changing the AC frequency. The fixed frequency is not able to change the operating frequency, it is a fixed operating frequency. The inverter press using frequency conversion control technology can automatically select the heating, cooling and dehumidification operation modes according to the ambient temperature, so that the room can quickly reach the required temperature in a short time, and in the state of low speed and low energy consumption with a small temperature difference fluctuation, to achieve fast, energy-saving and comfortable temperature control effect.

There are two core contents in the frequency conversion:

First, it is highly adaptable to various working conditions.

For example, when designing an elevator, there is a standard working condition, within a certain standard range, the elevator operates normally, and if it exceeds the standard range, the elevator will also run and usually burn the motor. A great feature of the heating field is the violent fluctuation of working conditions, such as from minus 25 degrees to more than 10 degrees Celsius to be able to heat, if the system does not have the ability to adjust, it is prone to problems. The fixed frequency machine is connected to the power, how to operate the machine is not artificially controlled, so the fixed frequency machine will appear overheating protection, burning the compressor phenomenon, especially in the defrosting time, there is no way to achieve a smooth switching, in some large machines, the defrost switch high and low pressure to hear a bang, and the core part of the frequency converter can be controlled, and the stability of the product is improved.

The second point is that the inverter is more energy-efficient.

Its energy saving is not in the coldest days, because in the coldest days, the equipment works at full frequency, which is the same as the fixed frequency machine. Energy saving is in those days when it is not cold, taking Beijing as an example, the weather below minus 10 degrees is very little, about 15%, this time is equivalent to the fixed frequency machine, but in the other 80%-85% of the time, when the frequency converter works at about 0 degrees, at 7 degrees, at the ambient temperature of minus 5 degrees, the compressor flow rate is equivalent to half, and the heat exchanger works at full frequency, which is equivalent to machine amplification from this point of view, so its efficiency is high.

What is Fixed Frequency Air Energy?

China's power grid voltage is divided into 220 volts, 50 Hz, 380 volts, and 50 Hz. The air energy operating under this voltage condition is collectively referred to as fixed-frequency air energy. Fixed-frequency air can rely on it continuously"On, stop"To adjust the indoor temperature, it is easy to cause the room temperature to be hot and cold between opening and stopping, and consume more electricity.

What is Variable Frequency Air Energy?

Variable frequency air energy can change the fixed frequency of 50 Hz to 20 Hz-120 Hz through the frequency conversion controller. It can adjust the power supply frequency of the compressor and fan at any time according to the environment and water temperature, adjust the speed of the compressor and fan, and realize stepless speed adjustment, so as to achieve reasonable use of energy.

When the system is started, the inverter air energy has a low current, which will not have an impact on the power grid and the watt-hour meter, and can reduce the interference to other electrical appliances in use in the room. The voltage adaptation range reaches 120V-270V, which solves the problem of affecting the work due to the instability of the voltage. The wider the frequency variation range, the more it can ensure non-stop operation in most working conditions, and the more obvious the energy-saving advantages.

The difference and advantages of air source heat pump frequency conversion and fixed frequency.

If the fixed frequency is always the rated power work, the frequency conversion will put in the appropriate power according to the load size, so the frequency conversion energy saving, power saving.

The difference between air energy frequency conversion and fixed frequency, the advantage of frequency conversion is different in the choice and principle. Advantages of air mold cracking gas energy inverter: high efficiency, long life, good stability and closure, and strong low-temperature heating.

The inverter air conditioner has a low starting current, which reduces the impact of pulse interference on other household appliances and is more energy-saving.

Luck is the original volume, just look for me. I don't know if I'm going to shoot this inverter, it's better for the air conditioner, and the thing is really there.

1) Heat pump: a device that transfers the work of a low-level heat source (obtained from air, water or soil in nature) to a high-level heat source (which can be used by people) through electricity, and can realize the heating of a landshed or a hot water system. (2) Air conditioning:

It is a device that makes the indoor air circulate continuously, absorbs heat or releases heat by using the state of the internal refrigeration heating medium to understand the changes of the land, and adjusts the indoor temperature. Air conditioning (3) Air energy: Air energy refers to the low-grade thermal energy contained in the air.

Heat pump is mainly used to use low-grade heat source device, air conditioning is mainly used to regulate indoor temperature device, air energy is a clean energy source.

Hello dear! We're happy to answer for you! Disadvantages of inverter air energy water heaters:

1. The complex design of the circuit control board leads to the probability of the occurrence of the control circuit board is greater than that of simple frequency conversion compression. In addition, the loss of the inverter (about 10% to 20% of the compressor power) in the summer will overheat the main control board. This is also the reason for the high incidence of control circuit failures.

2. Complex piping design increases the failure of system pipelines. 3. The variable speed leads to large wear and tear of the compressor and frequent failures, while the running speed of the fixed-speed compressor is constant, and the failure is less. 4. The lack of design of the inverter compressor leads to the indefinite inability to resist liquid shock, anti-fouling and anti-overload as good as the fixed frequency 5. The shortcomings of the inverter compressor in oil return lead to the difficulty of oil return, which increases the frequency of inverter system failures.

6.The application of inverter technology makes inverter air energy more than 5000 more expensive than fixed-frequency air energy.
