Speedy deletion nomination of Draft:Okmarts.com

If this is the first article that you have created, you may want to read the guide to writing your first article.
You may want to consider using the Article Wizard to help you create articles.

A tag has been placed on Draft:Okmarts.com, requesting that it be speedily deleted from Wikipedia. This has been done under section G11 of the criteria for speedy deletion, because the page seems to be unambiguous advertising which only promotes a company, group, product, service, person, or point of view and would need to be fundamentally rewritten in order to become encyclopedic. Please read the guidelines on spam and Wikipedia:FAQ/Organizations for more information.

If you think this page should not be deleted for this reason, you may contest the nomination by visiting the page and clicking the button labelled "Contest this speedy deletion". This will give you the opportunity to explain why you believe the page should not be deleted. However, be aware that once a page is tagged for speedy deletion, it may be deleted without delay. Please do not remove the speedy deletion tag from the page yourself, but do not hesitate to add information in line with Wikipedia's policies and guidelines. If the page is deleted, and you wish to retrieve the deleted material for future reference or improvement, then please contact the deleting administrator.

May 2020

There have been two problems with this account: the account has been used for advertising or promotion, which is contrary to the purpose of Wikipedia, and your username indicates that the account represents a business or other organisation or group or a web site, which is also against policy, as an account must be for just one person. Because of those problems, the account has been blocked indefinitely from editing. Additionally, if you receive, or expect to receive, compensation for your contributions to Wikipedia, you must disclose who is paying you to edit.

If you intend to make useful contributions other than promoting your business or organisation, you may request an unblock. To do so, post the text {{unblock-spamun|Your proposed new username|Your reason here}} at the bottom of your talk page. Replace the text "Your proposed new username" with a new username you are willing to use. See Special:CentralAuth to search for available usernames. Your new username will need to meet our username policy. Replace the text "Your reason here" with your reason to be unblocked. In that reason, you must:

Convince us that you understand the reason for your block and that you will not repeat the kind of edits for which you were blocked.
Describe in general terms the contributions that you intend to make if you are unblocked.

If you believe this block was made in error, you may appeal this block. To do so, please read the guide to appealing blocks, then add the text {{unblock|Your reason here}} at the bottom of your talk page, replace the text "Your reason here" with your reason for thinking that the block was an error, and publish the page.

How Air Conditioners Work

How Air Conditioners Work Air conditioners use refrigeration to chill indoor air, taking advantage of a remarkable physical law: When a liquid converts to a gas (in a process called phase conversion), it absorbs heat. Air conditioners exploit this feature of phase conversion by forcing special chemical compounds to evaporate and condense over and over again in a closed system of coils. The compounds involved are refrigerants that have properties enabling them to change at relatively low temperatures. Air conditioners also contain fans that move warm interior air over these cold, refrigerant-filled coils. In fact, central air conditioners have a whole system of ducts designed to funnel air to and from these serpentine, air-chilling coils.

When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again. To do that, a compressor puts the gas under high pressure, a process that creates unwanted heat. All the extra heat created by compressing the gas is then evacuated to the outdoors with the help of a second set of coils called condenser coils, and a second fan. As the gas cools, it changes back to a liquid, and the process starts all over again. Think of it as an endless, elegant cycle: liquid refrigerant, phase conversion to a gas/ heat absorption, compression and phase transition back to a liquid again. It's easy to see that there are two distinct things going on in an air conditioner. Refrigerant is chilling the indoor air, and the resulting gas is being continually compressed and cooled for conversion back to a liquid again. On the next page, we'll look at how the different parts of an air conditioner work to make all that possible.
