 التدهور هو عملية التحلل التدريجي لشيء مادي أو معنوي، تؤدي إلى تدهور حالته أو جودته بمرور الوقت.

Deterioration is the gradual process of breaking down or worsening of a material or condition, leading to a decline in its state or quality over time.

 Refrigerants هي المواد التي تستخدم في أنظمة التبريد والتكييف لنقل الحرارة وتحويلها من مكان إلى آخر.

Refrigerants are substances used in refrigeration and air conditioning systems to transfer heat from one place to another.

"Hydrochlorofluorocarbons" are chemical compounds used in industries such as refrigeration, air conditioning, and pharmaceutical aerosols. The word combines the roots "hydro" for hydrogen, "chloro" for chlorine, "fluoro" for fluorine, and "carbon" for carbon. They were previously used as alternatives to chlorofluorocarbons, which were banned due to their harmful effects on the ozone layer.

Air conditioner: مكيف الهواء

Air conditioning: تكييف الهواء ، تبريد الهواء

The word "condenser" refers to a device used to convert gas into liquid by cooling it. Typically, condensers are used in refrigeration and air conditioning systems to convert vapor into liquid at a low temperature. It's an essential component in the refrigeration cycle, helping to lower the gas temperature and convert it into the desired liquid form.

Critical: حاسم 

Extremely important or necessary for the success, continuation, or development of something.

مهم للغاية أو ضروري لنجاح أو استمرار أو تطور شيء ما
