Pipe systems, which can be one-piece or air-to-air systems, are ventilated outwards via air ducts. The one-piece type collects water in a bucket or tray and stops when it is full. The air-to-air type evaporates the water again and drains it through the duct pipe and can operate continuously. These portable units attract indoor air and drain it to the outside through a single channel. [Citation needed] The Kigali Amendment to the Montreal Protocol is an international agreement to progressively reduce the consumption and production of hydrofluorocarbons (HFCs). It is a legally binding agreement that aims to establish rights and obligations under international law.  The 2016 Kigali Agreement adds HFCs to the list of substances to be phased out under the Montreal Protocol. Those who ratify the agreement commit to reducing the production and consumption of HFCs by more than 80% over the next 30 years. Passive techniques remained widely used until the 20th century, when they went out of fashion and were replaced by a motorized air conditioner. Using information from technical studies of traditional buildings, passive techniques for 21st century architectural designs are revived and modified.   Members threatened not to renew their membership. if the AAPG does not change its position on global climate change. And members who have already resigned in recent years because of our current position on global climate change have told me.
The current policy statement is not supported by a significant number of our members and potential members.  Free cooling can sometimes be chosen when the outside air is cooler than the indoor air and therefore the compressor does not need to be used, resulting in high cooling efficiencies for these periods. This can also be combined with seasonal storage of thermal energy. In 1758, Benjamin Franklin and John Hadley, professor of chemistry at the University of Cambridge, conducted an experiment to explore the principle of evaporation as a means of rapid cooling of an object. Franklin and Hadley confirmed that evaporation of highly volatile liquids (such as alcohol and ether) could be used to lower the temperature of an object beyond the freezing point of water. They conducted their experiment using the bulb of a mercury thermometer in the glass as an object and with a bellows used to accelerate evaporation. They lowered the thermometer lamp temperature to -14°C (7°F), while the ambient temperature was 18°C (64°F). Franklin noted that shortly after passing the water`s freezing point of 0°C (32°F), a thin film of ice formed on the surface of the thermometer`s bulb and the ice mass was about 6 mm (1⁄4 in.) thick when they stopped the experiment from reaching -14°C (7°F). Franklin concluded, “From this experiment, one can see the possibility of freezing a man to death on a hot summer day.”  Since 2001, 34 national academies of sciences, three regional academies and the International InterAcademy Council and the International Council of Academies of Engineering and Technological Sciences have issued official statements affirming human-caused global warming and calling on nations to reduce greenhouse gas emissions. Among the 34 declarations of the National Academy of Sciences are 33, which signed joint declarations of the Academy of Sciences and an individual declaration of the Polish Academy of Sciences in 2007. The 1989 Montreal Protocol is not a climate agreement. Instead, it aims to protect the Earth from ozone-depleting chemicals such as chlorofluorocarbons or CFCs, which were used in the air conditioning and refrigerant industries. The widespread use of CFCs had caused a hole in the ozone layer of the atmosphere, allowing some harmful radiation to reach The Earth.
This radiation was considered a potential health hazard. The Montreal Protocol has led to the replacement of CFCs by HFCs that do not destroy the ozone layer. Later, however, it turned out that they are extremely effective in causing global warming. HfCs have therefore solved one problem, but contributed significantly to it in another. But these could not be phased out under the original provisions of the Montreal Protocol, which was intended solely to phase out ozone-depleting chemicals. The Kigali Amendment allowed the Montreal Protocol to also require the phase-out of HFCs. Air conditioners reduce the absolute humidity of the air treated by the system when the surface of the evaporator coil is significantly colder than the dew point of the ambient air. An air conditioner designed for an occupied room usually achieves a relative humidity of 30% to 60% in the occupied room.  This scientific opinion is expressed in synthesis reports, by nationally or internationally renowned scientific bodies and by opinion polls among climatologists.
Scientists, universities and laboratories contribute to global scientific opinion through their peer-reviewed publications, and the areas of collective bargaining and relative safety are summarized in these prestigious reports and surveys.  The IPCC`s Fifth Assessment Report (AR5) was finalized in 2014.  Its findings are summarized below: This agreement mandated countries to reduce the production of hydrofluorocarbons (HFCs) by about 80-85% by 2045. The reference levels of different countries were different. As a result of this leak, the global average temperature would rise by only 0.5 degrees by 2100. Thus, the Kigali Agreement is an amendment to the Montreal Protocol. Five years after struggling to negotiate favourable terms for itself, India decided on Wednesday to ratify an important amendment to the Montreal Protocol that made the 1989 Ozone Reduction Agreement an extremely effective weapon in the fight against climate change. It was at the 28th Meeting of the Parties to the Montreal Protocol that negotiators from 197 countries signed the Agreement Amending the Montreal Protocol. This happened in Kigali, which is how the name Kigali Agreement was born. As a long-time pioneer in the implementation of the Montreal Protocol, India`s ratification is a major step towards the success of the Kigali Amendment.
China ratified the agreement earlier this year, along with 121 other countries that have ratified it so far. There is now a broad consensus that the Earth is warming due to greenhouse gas emissions caused by human activities. It is also clear that current trends in energy consumption, development and population growth will lead to persistent – and more severe – climate change. While the hole in the ozone layer has since recovered, the treaty was amended in 2016 (for the ninth time) to include hydrofluorocarbons (HFCs), which contribute significantly to global warming. .
