Here’s our guide to the essential appliances for a cozy summer home.

In the era of technology surging forward, the field of home appliances is undergoing a quiet but profound change, refrigerators also quietly put on a new energy-saving outfit. When the concept of environmental protection like spring breeze blowing into every corner of life, when the energy crisis like a cloud over the world, we are increasingly concerned about the energy consumption of home appliances. As a pioneer of energy saving, frequency conversion refrigerator, with the wisdom of science and technology and the gentleness of the Earth, has entered thousands of households.

(1)、Frequency conversion compressor technology

1. core energy conservation mechanisms

The core component of frequency conversion compression technology is the frequency conversion compressor, which can be flexibly adjusted according to the actual temperature demand in the refrigerator. When the temperature change is small, the compressor runs at a lower speed to maintain the temperature stability in the refrigerator. When the temperature fluctuates greatly and it needs to be cooled quickly, it will gradually increase the speed and increase the refrigeration intensity.

2. improving energy efficiency

By adjusting the speed in real time, the frequency conversion compression technology can accurately match the cooling demand and avoid the energy loss of frequent start and stop. The power is greatly reduced at low frequency operation, and the energy consumption is reduced by rapid cooling at high frequency. The comprehensive energy efficiency ratio is increased by more than 30% at fixed frequency, and significant energy saving effect is achieved.

(2)、Intelligent Temperature Control System

The energy saving advantage of frequency conversion refrigerator is inseparable from the precise regulation of its intelligent temperature control system.

1. multi-sensor collaboration

Inside the refrigerator, a temperature sensor, a humidity sensor and a door switch sensor are closely matched. Temperature sensors are located in every corner of the refrigerator, accurately sensing subtle temperature changes, avoiding frequent start and stop of the compressor due to excessive temperature fluctuations, and reducing unnecessary energy consumption. The humidity sensor monitors the humidity in real time to prevent excessive refrigeration caused by abnormal humidity and reduce energy waste. Once the door is opened, the system quickly adjusts the operation mode to slow down the loss of cold air and reduce the subsequent high-load operation time of the compressor. The data of the three are analyzed by intelligent algorithms, and the refrigeration strategy is dynamically optimized to make the compressor run under the best working conditions, maintain a stable environment in the refrigerator with the lowest energy consumption, and achieve the perfect balance between energy saving and preservation.

2. district temperature control

The partition temperature control design of frequency conversion refrigerator provides a strong support for energy saving. Refrigerator is divided into a number of independent temperature zone, each temperature zone has its own temperature sensor and refrigeration control module. After the user sets the temperature of each temperature zone on demand, the system will be accurately controlled. When a certain temperature zone reaches the set temperature, the corresponding refrigeration device will stop working or run at low power to avoid energy waste caused by global refrigeration.

(3)、Efficient system design

In addition to the compressor and temperature control system, the frequency conversion refrigerator’s high efficiency system design also has made the great contribution for the energy conservation.

1. pipeline layout

In terms of piping layout, engineers have carefully designed and optimized the refrigerant flow path, so that the refrigerant can circulate more smoothly inside the refrigerator, improving refrigeration efficiency and reducing energy consumption.

2. vacuum insulation

The application of vacuum insulation layer is also a bright spot. This special insulation material, can effectively prevent the external heat transfer into the refrigerator interior. Compared with traditional insulation materials, the vacuum insulation layer improves the thermal insulation performance by several times, which greatly reduces the energy consumption of refrigerators to maintain low temperatures.

(4)、Low power standby mode

In the pursuit of green energy saving and efficient preservation of the moment, the low energy standby mode of variable frequency refrigerator stands out.

1. intelligent dormancy

The frequency conversion refrigerator monitors the temperature, humidity and door opening frequency in real time through the built-in sensor, and predicts the use demand with the intelligent algorithm. When there is no operation for a long time and the temperature is stable, it can automatically reduce the speed of the compressor and the fan to the lowest gear, maintain the basic refrigeration, and turn off the unnecessary lighting and display screen. The standby power consumption can be reduced by more than 40% , realize silent operation with low energy consumption.

2. recover quickly

When an open door pick-up is detected or the temperature fluctuation exceeds the threshold, the frequency conversion system immediately activates the emergency response: the compressor jumps from low speed to high speed operation in 1.2 seconds, and the fan is synchronously raised to the highest gear, form a strong circulation of cold air. Through multi-dimensional cold precision delivery, the temperature of the cold storage room can be restored within 3 minutes, taking into account energy saving and food preservation.

Conclusion

With its advanced frequency conversion compressor technology, intelligent temperature control system, high efficiency system design and low energy consumption standby mode, the frequency conversion refrigerator shows excellent performance in energy saving. It not only brings convenience to our life, but also saves energy and reduces the cost of living. In the pursuit of green, environmental protection, energy-saving today, frequency refrigerator is undoubtedly our ideal choice. Let’s embrace technology and enjoy the new life of energy saving brought by frequency conversion refrigerator.
