Description

technical field [0001] The invention relates to an air-conditioning and refrigeration system, in particular to an air-conditioning and refrigeration system using liquid metal to cool down a condenser so as to transfer its heat to the surrounding air. Background technique [0002] Air-conditioning is known as one of the greatest inventions of mankind in the twentieth century. Its appearance has freed mankind from passive dependence on the environment. When the air conditioner is in cooling operation, the low-temperature and low-pressure refrigerant gas is sucked by the compressor and pressurized to become a high-temperature and high-pressure refrigerant gas. After condensing and releasing heat in the outdoor heat exchanger (condenser), it becomes a medium-temperature and high-pressure liquid. The high-pressure liquid becomes a low-temperature and low-pressure liquid after being throttled and decompressed by the throttling part. The low-temperature and low-pressure liquid refr...

AI Technical Summary

Problems solved by technology

In order to ensure the normal operation of the air conditioning system, increasing the system power becomes a direct choice; however, after the power is increased to a certain level, the fan speed will be greatly increased, and the power consumption and noise will be significantly increased, especially in summer when the air conditioner is most used. , the power consumption of air-conditioning has been getting higher and higher, exceeding 40% of the total power consumption in many cities at peak times, such a high power consumption of air-conditioning has increased the power load of the country and put a huge pressure on resources

In addition, the outdoor air temperature is high in summer, and the heat transfer temperature difference of the air conditioner is small. The condenser is mainly cooled by air, and the thermal conductivity of the air is small. Although there are fans to accelerate the air flow, the heat transfer performance is still limited.

Therefore, many researchers have carried out in-depth research and improvement on this, and proposed various methods such as water cooling and phase change cooling, but there are still many problems such as inconvenient use, low efficiency, troublesome maintenance, etc.
