Advantages and disadvantages of inverter and fixed frequency air conditioning

1, inverter air conditioning advantages:

Can be better control of the temperature in the room, so that the temperature fluctuations in the room is smaller; in some specific conditions, inverter air conditioning efficiency is higher; to obtain the same air conditioning effect under the premise of smaller power consumption; inverter air conditioning compressor start and stop less frequently, under certain conditions to reduce the power consumption.

2, inverter air conditioning shortcomings:

Electrical control design is complex, high cost, the failure rate is also very high; electrical control components failure maintenance cost is high; inverter air conditioning in the low load operation will have a significant low-frequency noise; inverter air conditioning in the room with the actual size of the cold load does not match the air conditioning capacity of the small time long time high-frequency operation, the air conditioning life becomes shorter.

3, the advantages of fixed-frequency air conditioning:

Fixed-frequency air conditioning energy-saving indicators also depend on the product's energy-efficiency ratio, the higher the energy-efficiency ratio is the more energy-efficient, on the contrary, the more power-consuming. Most of the high-energy air conditioners on the market today are mainly fixed-frequency air conditioners, and the overall decline in market prices has led to fixed-frequency products are very popular.

4, fixed-frequency air conditioning shortcomings:

Contrast with the inverter air conditioning, fixed-frequency air conditioning is not so smart. In many large public **** occasion is not very good operation, temperature control is not as convenient as inverter air conditioning, the overall power consumption than inverter air conditioning.

Expanded information:

Fixed-frequency air conditioning works:

The compressor compresses the gaseous refrigerant into a high-temperature, high-pressure liquid refrigerant, and then sends it to the condenser to dissipate the heat into a room-temperature, high-pressure liquid refrigerant, so that the outdoor unit is blowing a hot air.

Then to the capillary tube, into the evaporator, because the refrigerant from the capillary tube to reach the evaporator after the sudden increase in space, the pressure decreases, the liquid refrigerant will be vaporized into a gaseous low-temperature refrigerant, which absorbs a large amount of heat, the evaporator will become cold.

The fan of the indoor unit blows the indoor air through the evaporator, so the indoor unit blows out cold air; the water vapor in the air will condense into water droplets when it encounters the cold evaporator, and flow out along the water pipe, which is the reason why the air conditioner will come out water.

There is a component called the four-way valve when heating, so that the refrigerant in the condenser and evaporator flow in the opposite direction of refrigeration, so when heating outdoor blowing cold air, indoor machine blowing hot air.
