Definition of Frequency Conversion Air Conditioner and Fixed Frequency Air Conditioner

Inverter air conditioner

Inverter air conditioner is based on the ordinary air-conditioning selection of the inverter dedicated compressor, an increase of the frequency control system. Its basic structure and cooling principle and ordinary air conditioning exactly the same. The inverter air conditioner mainframe is automatically variable speed, it can automatically provide the required room according to the cold (heat) the amount; when the indoor temperature reaches its desired value, the air conditioning host is able to accurately maintain the temperature of the constant speed of operation, To achieve "non-stop operation", so as to ensure the stability of the ambient temperature.

Fixed air conditioning

State home power grid voltage of 220 volts, 50 Hz, in this condition work air conditioning called fixed frequency air conditioning. As the power supply frequency can not be changed, the traditional fixed-frequency air compressor compressor speed is basically the same, relying on constantly "open, stop" compressor to adjust the indoor temperature, the opening and closing between the likely room temperature caused by hot and cold, and consumption More power.

Advantages: comfort

Fixed-frequency air-conditioning use the opening and closing to adjust the room temperature, temperature range of ± 2 ℃, room temperature fluctuation range, people will feel uncomfortable, easy to get "air conditioning disease", and inverter air conditioner at the beginning of high-speed operation Room temperature to set the temperature to low frequency work, temperature control accuracy, temperature range of ± 0.5 ℃, so that the indoor temperature to maintain a constant, better comfort, especially for the elderly and children sleep when used.

Advantage 2: energy saving

Inverter air conditioner does not start as often as the fixed frequency, will not produce a momentary instantaneous high current; inverter air conditioner after the start of the maximum frequency of operation, when the room temperature to set the temperature, to low frequency operation, because at low frequencies High efficiency, compared with the fixed speed machine, can achieve substantial energy saving. According to statistics, all-DC inverter air conditioner than the fixed-frequency air-conditioning efficiency increased by about 40%, ordinary DC inverter air conditioner than the efficiency of air conditioning increased by about 30%.

As the inverter air conditioner through the built-in inverter, at any time to adjust the air conditioner heart - the compressor speed, so as to make rational use of energy; because of its compressor will not be frequent open, will make the compressor to maintain a stable working condition, which can So that the overall air conditioning to achieve more than 30% energy saving effect. At the same time, this reduction in noise and extend the life of air conditioning, there is a very significant role.

Advantages three: low voltage requirements

Inverter air conditioner on the strong adaptability of the voltage, and some inverter air conditioner can even start in the 150 - 240V voltage. Inverter air conditioner and fixed frequency air conditioning difference: low ambient temperature requirements

Frequency conversion of air conditioning on the ambient temperature quasi-quasi-strong, even in a 15t ambient temperature start. Inverter air conditioner and fixed frequency air conditioning difference: high precision temperature control

It can change the compressor speed to control the air conditioning (heat) volume. Its cooling (heat) the amount of a change in the range, such as 36GW frequency of cooling capacity changes to 360-400W, heating changes to 300-6800W, so the indoor temperature control can be accurate to ± 1 ℃, so that the body is very comfortable.

Advantage four: low noise

Inverter air conditioner running balance, vibration reduction, noise also will be reduced.

Advantages of five: refrigeration, heating capacity

The higher the frequency of the inverter air conditioner compressor, the higher the operating speed of the compressor, the stronger the cooling and heating capacity, the faster the temperature change in the room. Inverter air conditioner after the start of the maximum frequency operation, the frequency up to 130Hz or more, the cooling and heating capacity is fixed speed machine (50Hz) 2 to 3 times, so that the room cooling or heating rate faster than the fixed speed air conditioner 1 to 2 times The So that people quickly get a comfortable temperature environment.

Advantage 6: speed up the speed

When the room temperature and set the temperature difference is large, the inverter air conditioner a boot, that is, the maximum power to work, so that the rapid rise or fall to the room temperature to set the temperature, cooling (heat) effect is obvious. It intelligently discerns the size of the room and distributes the amount of cold (heat) to keep the same room in the same size. Inverter air conditioner with a variable frequency compressor, inverter air conditioner according to the room cold (heat) load changes automatically adjust the compressor operating frequency. To set the temperature after the inverter air conditioner to operate at a lower frequency, to avoid the sudden changes in room temperature caused by discomfort. When the load is low, the operating frequency is low, and the compressor consumes little power at the same time, while avoiding frequent opening and closing, and thus more power. Frequency conversion air conditioner and fixed frequency air conditioning difference: refrigeration, heating capacity

The above is the difference between inverter air conditioner and fixed frequency air conditioner, relative to the fixed frequency air conditioner, inverter air conditioner can be more comfortable to achieve the unity of energy conservation.
