On June 28th, the World Meteorological Organization said that from 2015 to 2019, it is very likely that it will become a zui fever for 5 years since the temperature record, and the actual situation immediately gave a positive response. It is reported that Europe, which has always had a pleasant climate, was hit by heat waves for six consecutive days last week. On June 28, Garalle Montier in southern France measured a high temperature of 45.9 degrees Celsius, and parts of Spain exceeded 40 degrees Celsius.

Under high temperature, seeking a cool place is the primary choice for survival. Air conditioning has also become the first choice, and it is also the embodiment of technology to provide people with better living conditions. However, the use of air conditioners will also cause an increase in the ambient temperature. There seems to be a contradiction between the use of air conditioners to ensure health and normal survival and environmental protection, and this contradiction is also focused on China's current use of air-conditioning in the world. According to data from the International Energy Agency (IEA) in 2016, of the world's 1.6 billion air conditioners, Europe alone accounts for only 6%, Japan accounts for 9.2%, the United States accounts for 23%, and China accounts for 35.1%. As a global air-conditioning manufacturing and consuming country, China's refrigeration power consumption accounts for more than 15% of the total electricity consumption in the whole society, with an average annual growth rate of nearly 20%.

The use of air conditioning may affect the atmospheric temperature. The first is that the operation of air conditioners requires electricity to be maintained, and electricity production emits a large amount of carbon dioxide and other greenhouse gases. Second, the refrigerant used in air conditioning will also release greenhouse gases into the atmosphere. Moreover, the causal relationship between the use of air conditioners and the increase of greenhouse gases is also relatively clear, and the fuel required for power generation is mainly fossil fuels. Therefore, the use of greenhouse gases emitted by air conditioners will affect the climate more or less.

However, in the face of the environment and climate, human survival is the main thing. Only by satisfying this premise can we take environmental protection into consideration and have better environmental protection. Without healthy people, even human life is difficult to protect in the face of heat waves, environmental protection will lose its meaning, and there will be no environmental protection. In this regard, Europe is also changing its mindset.

For air-conditioning, Europeans have always been excluded. Whether it is Germany or Belgium, or France, the average family does not have air-conditioning, and even Switzerland has laws that prohibit air-conditioning. The Swiss believe that air-conditioning consumes electricity to increase greenhouse gas emissions, and also emits a large amount of chemical substances that pollute the air, which is detrimental to human health. Natural ventilation is good, the temperature is too hot, just use an electric fan. However, it is reported that the high temperature in Europe in the previous week has made Germany, France and other countries not only in short supply of electric fans, but also become a hot commodity. According to EU statistics, the number of households installing air conditioners in Europe is about 5% today, but the latest market assessment of the International Energy Agency predicts that demand for air-conditioning equipment in Europe will at least double in the next 20 years, as climate change causes record high temperatures to ravage Europe. The frequency is increasing, and the time is constantly increasing.

The use of air conditioners is for a better life, and the use of air conditioners may not be incompatible with environmental protection. It is possible to achieve a certain degree of consideration in a certain way. On June 14, the National Development and Reform Commission and the Ministry of Industry and Information Technology jointly issued the “Green Efficient Refrigeration Action Plan”, which clearly stated the short-term and medium-term goals for the development of the refrigeration industry, and significantly improved the energy efficiency standards and upgrades of refrigeration products. Green high-efficiency refrigeration products supply, promote green and efficient refrigeration consumption, and promote energy-saving renovation in the refrigeration sector, comprehensively improve the overall energy efficiency of the refrigeration industry, and promote the green and high-quality development of the refrigeration industry. While cultivating new kinetic energy for green development in China, it will help globally “cool down”.

In addition, as a user, the use of air-conditioning is energy-saving, using yi-class energy-efficient environmentally-friendly air conditioners. According to national energy efficiency standards, the same level of air-conditioning energy-efficiency conversion with cooling capacity is about 20% more energy-efficient than three-level energy-efficiency frequency conversion. It is about 60% energy saving than the three-level energy efficiency fixed frequency. Therefore, the frequency conversion yi level is not only more energy efficient, but also more comfortable. In addition, if the temperature is adjusted to above 26 degrees Celsius, in summer, the lower the room temperature is adjusted, the more electricity is consumed, and the room temperature can be increased by more than 10% per room temperature when cooling. At present, the standard for air conditioning in public places in summer is ≥26 °C. If the air conditioner temperature is set at 26-28 °C, it is not only easier to blow sickness, but also more energy-saving and environmentally friendly. In addition, the adjustment to the automatic mode, sleep at night, air conditioning timing, open for about 3 hours, because the body is not sensitive to heat after falling asleep, and the weather is cool in the latter half of the night. The air conditioner automatically increases the indoor temperature, and the sleep function can achieve a 20% power saving effect.

In the public domain, the government should encourage and require air-conditioned public facilities to be open to the public, such as libraries, cinemas, restaurants, supermarkets, subways and bus stops, coffee shops, etc., to attract the public and reduce home air conditioning. use. In addition, we must also create conditions to provide natural summer cooling venues, such as parks, rivers and lakes, forests and fountains, water sprays and street cooling.
