Portable Air Conditioner with R290 Environmental Friendly Refrigerant, A Magic Weapon to Save the Earth from Cooling

During this time, one of the most discussed topics is: what is the maximum temperature today? Today’s temperature has reached a new high, and so on.

Since June 13, China has witnessed the first regional high-temperature weather process this year, which has a wide range, long duration, strong extremes and great impact. It covers an area of 5.021 million square kilometers and affects more than 900 million people.

In addition to China, rare high-temperature weather has occurred all over the world. India and Pakistan have been suffering from extreme heat for several weeks, and the capital of India is close to 50 degrees.

The same is true in Europe. In recent days, Spain, Portugal, France, Italy, Britain and other European countries have been hit by a heat wave, with temperatures exceeding 40 degrees. Temperatures in some areas have soared to new highs in decades, and drought, wildfires and other serious problems in some areas.

Why is there such extreme high temperature this year?

The main reason is global warming. Since 1800, human activities have been the main cause of climate change. The greenhouse gas emissions that lead to climate change include carbon dioxide and methane.

The increase in the number of cars, the emission of waste gas and water from factories, the burning of garbage, the burning of fossil fuels such as coal, oil and natural gas, and the cleaning of land and forests will all produce a large number of nitrogen oxides, methane, carbon dioxide, coal ash and dust, which can absorb the energy of thermal radiation in the environment. They produce the well-known “greenhouse effect“, just like a blanket wrapped around the earth, causing the temperature of the earth to rise.

At the same time, the earth’s absorption of heat from the sun has increased significantly, resulting in the earth’s energy imbalance. Scientists believe that the earth’s energy imbalance is caused by human factors and changes within the earth system. The doubling of the earth’s heat absorption is partly due to the increase in greenhouse gas emissions and the reduction in clouds and ice.

With the increase of greenhouse gas emissions, the earth’s atmosphere retains more heat, so that the thermal radiation that would have entered space can not be taken away. Because clouds and ice can rebound solar thermal radiation, the reduction of clouds and ice will further exacerbate global warming.

The sharp increase in population is also one of the main factors leading to global warming. At the same time, it also seriously threatens the balance between the natural ecological environment. Now the total population of the world is close to 8 billion, and only the amount of carbon dioxide emitted by human beings is an amazing number every year. The result will directly lead to the continuous increase of carbon dioxide content in the atmosphere, aggravate the degree of greenhouse effect, and lead to the emergence of extreme high temperature weather around the world.

In addition, excessive tree cutting and insufficient green vegetation to regulate the balance of nature are also one of the reasons for the rise of global temperature.

As a result, the concentration of greenhouse gases reached the highest level in 2million years, and emissions continued to rise. According to statistics, the earth is now about 1.1 ° C higher than that in 1800. The past decade (2011-2020) has been the hottest on record.

Many people believe that climate change will only lead to higher temperatures. But rising temperatures are just the beginning of the story. Because the earth is an interconnected system, changes in one region will affect changes in all other regions.

The consequences of climate change include severe droughts, serious fires, sea-level rise, floods, melting polar ice, catastrophic storms and declining biodiversity. These will make irreversible and disastrous changes to the earth on which we live, making it more difficult for organisms on the earth, including our human beings, to survive on the earth. Finally, the earth may no longer be suitable for biological reproduction.

Everyone is responsible for protecting the earth. As a reliable portable air conditioner manufacturer of environmental household appliances company which trusted by customers, we have always been committed to “the comfort and environmental protection of the home and the earth environment“. In order to achieve this goal, UnitedStar has been committed to the research, development and production of high-quality mobile air conditioners that can not only meet the cooling needs of customers, but also developed the production line of the new environmentally friendly refrigerant R290, which was still used by relatively few people in China at that time, fulfilling the mission of environmental protection.

R290 is a new environmentally friendly refrigerant, colorless and slightly soluble in water. Its chemical composition is propane (CH3CH2CH3), and its toxicity is very small.

R290 uses hydrocarbon as a new environmentally friendly refrigerant, replacing R22 refrigerant that will destroy the ozone layer and R410A that produces greenhouse gases. It can be easily extracted from oil and natural gas, it is a natural cracking refrigerant.

Compared with Freon, a synthetic cracking refrigerant, the molecule of natural substance I R290 does not contain chlorine atoms, so the ODP value is zero and does not damage the ozone layer. In addition, compared with HFC substances that also have no destructive effect on the ozone layer, the GWP value of R290 is close to 0 and has no impact on the greenhouse effect.

ODP (ozone depression potential) is the ozone depletion potential. The smaller the ODP value, the better the environmental characteristics of the refrigerant. According to the current level, it is considered that the refrigerant with ODP value less than or equal to 0.05 is acceptable.

GWP (global warming potential) is the global warming potential. It evaluates the destructive capacity of greenhouse gases in a certain period of time in the future, usually measured in 20 years, 100 years and 500 years. Generally, due to the natural decomposition and destruction mechanism, the concentration of existing greenhouse gases in the atmosphere decreases year by year, and the greenhouse effect ability is also weakened. However, for some CFC family gases, the atmospheric retention time is quite long, and the GWP value in 100 years may be higher than that in 20 years.

According to the Convention, the GWP value of carbon dioxide is 1, and the ratio of other gases to carbon dioxide is taken as the GWP value of the gas. The GWP value of other greenhouse gases is generally much higher than that of carbon dioxide, but due to their low content in the air, we still believe that carbon dioxide is the culprit of the greenhouse effect, which accounts for 60% of the greenhouse effect.

In addition, R290 has good thermal performance, large latent heat of gasification and less liquid filling capacity of the system. Under the same working conditions, the exhaust temperature can be 20 ℃ lower than R22, which is widely used in China, which is conducive to extending the service life of the compressor.

Portable air conditioner company UnitedStar’s mobile air conditioner has reached the Class A energy efficiency standard (European standard, the highest energy efficiency standard). It uses high-efficiency compressors and heat exchangers. Through energy-saving technology, it can improve energy efficiency, reduce power consumption, and achieve the effect of energy conservation and power saving. It can also save the power rate when we enjoy the coolness in the hot summer.

Besides the above advantages, our portable ac has below advantages:

1.We owned BSCI Certification

2.5 function in 1: refrigeration, heating, air supply, dehumidification and purification, which is able to satisfy your different demands all year round.

3.24-hour timer setting. You can easily set up to automatically turn off the device to help save energy. 

4. Easy to move and assemble. Our portable ac has Universal wheels so you can move it anywhere you like to keep cool in any space.

5.WIFI function and LED display. You can control the machine with Tuya WIFI.

6.No water out when cooling.

7.Dehumidification is separated from the refrigeration drain to prevent drainage from entering the water wheel during dehumidification, so as to circulate and humidify the air and reduce the dehumidification efficiency.

8.Our new model SKY-7A even has several air freshen functions: anion, activated carbon and HEPA, quickly kill germs and virus to keep fresh air in your space.

In this almost unprecedented summer, if you want to buy an air conditioner to cool down, remember to use the environmentally friendly refrigerant R290 portable air conditioner first!
