California's high temperature power rationing, new refrigeration equipment may ease the power shortage

In 1995, in order to remind people of the status of the ozone layer, the United Nations established the International Ozone Layer Protection Day on September 16 every year. This year's Conservation Day is also coming, and this week's environmental protection topic will be one of the hot spots.

Among them, the debate on air conditioning should be very fierce. As we all know, Freon, the refrigerant used in air conditioners, is the direct cause of the ozone hole. Therefore, the reform of the refrigeration system has been very fierce in the past years. Especially, the recent report shows that people begin to have more requirements for the future when the ozone layer is healing.



 

This is also of great significance to the current high temperature power consumption limit in California. The latest refrigeration technology, solar refrigeration, may fundamentally relieve the power pressure under temperature and reduce environmental pollution.



 

The high temperature and mountain fire in California keep on

Since September, the Mediterranean climate of California in the United States should have ushered in a cool autumn. Unfortunately, this year's abnormal high temperature has continued since summer, and forest fires still occur.

According to the news released by the California Forestry and Fire Department on September 11, the latest mountain fire has spread rapidly in the mountains of central California. In just a few days, the area of fire has exceeded 160 square kilometers and extended to northern California. At present, only 10% of the fire is under control, and the cause of the fire is still under investigation.

For the safety of the people, the government suggested that residents in the fire area evacuate urgently. California residents may be accustomed to this situation. In fact, many fires have occurred in California since July this year, where a large area of wildfires occurred. Because the extreme high temperature continues, the fire cannot be effectively controlled.





In addition, it is worth mentioning that the fire is not only out of control, but also California's fragile power grid. Affected by the surge in power demand for refrigeration equipment, California Electric Power entered an emergency state a few days ago. Large area blackouts occurred in some areas.




Implore the public to restrict the use of electricity

The extreme high temperature has pushed up the demand for electricity for residents, which has overwhelmed California's power system. Many people in California received a similar “Flex Alert” last week.

The day before the California government sent the mobile phone warning, several cities in California had been forced to cut off power for several hours under the temperature of 40 ° C. Last Tuesday night, the peak load of California's power grid had reached 52000 MW, exceeding the previous record of 50000 MW set in 2006. 520000 residents will be affected by power failure.
 

In addition to the warning information, residents are also required to set the air conditioning temperature above 26 degrees and turn off all unnecessary electrical appliances and lighting between 3 p.m. and 10 p.m. Residents with smart thermometers in their homes will also receive product reminders to minimize the use time of the central air conditioner or increase the temperature of the air conditioner during peak power consumption.



Although the emergency state of California power grid has been cancelled on September 8, the continuous high temperature still risks the collapse of the power grid. Therefore, as a direct cause, the use of air conditioners has increased dramatically. If the refrigeration technology with independent power supply can be popularized, the pressure on the power grid may be relieved. Coincidentally, this technology is available at present, and it is also very environmentally friendly. This technology is photovoltaic refrigeration。
