Q1. How does AC work what it's principle
Ans. 
AC works by transferring heat from inside a building to outside, using a refrigeration cycle.
• AC units contain a refrigerant that absorbs heat from indoor air and releases it outside.

• The refrigerant evaporates at low pressure and temperature, absorbing heat in the process.

• The refrigerant is then compressed, raising its temperature and pressure, before releasing the heat outside.

• The cycle continues to maintain a comforta...read more

Q2. What kind of gases are in AC
Ans. 
The gases in an AC unit typically include refrigerant gases such as R-410A or R-22.
• Refrigerant gases are used in AC units to absorb and release heat in order to cool the air.

• Common refrigerant gases used in AC units include R-410A (Puron) and R-22 (Freon).

• These gases circulate through the AC system in a continuous cycle to facilitate the cooling process.

Q4. Why the copper pipe between indoor unit and outdoor unit is covered by foam and white roll
Ans. 
The copper pipe between indoor and outdoor units is covered by foam and white roll for insulation and protection against external elements.
• The foam provides insulation to prevent heat loss or gain during the refrigerant transfer process

• The white roll acts as a protective layer to shield the copper pipe from external damage such as UV rays, moisture, and physical impact

• The insulation and protection help maintain the eff

Q5. Why we loosing the flare nut in union is kept by two adjustable spanner
Ans. 
Using two adjustable spanners to tighten a flare nut in a union can lead to it loosening due to uneven pressure distribution.
• Using two adjustable spanners can result in uneven pressure being applied to the flare nut

• This can cause the flare nut to become loose over time

• It is recommended to use a proper flare nut wrench for tightening flare nuts in unions
