Shri Refrigeration Services Interview Questions, Process, and Tips

I recommend a split system air conditioning system for its efficiency and flexibility.

• Split system ACs are energy efficient and provide better temperature control.

• They are versatile and can be installed in different rooms or zones.

• Split systems are quieter compared to window units.

• Examples: Mitsubishi Electric split system, Daikin split system.

There are various types of refrigerators available for different needs and preferences.

• Top freezer refrigerator

• Bottom freezer refrigerator

• Side-by-side refrigerator

• French door refrigerator

• Compact refrigerator

• Built-in refrigerator

• Counter-depth refrigerator

Types of compressors include reciprocating, rotary, scroll, and centrifugal.

• Reciprocating compressors use pistons to compress refrigerant gas.

• Rotary compressors use rotating vanes or blades to compress gas.

• Scroll compressors use spiral-shaped scrolls to compress gas.

• Centrifugal compressors use high-speed rotating impellers to compress gas.

• Examples: Copeland Scroll Compressor, Danfoss Reciprocating Compressor, Hitachi R

There are several types of refrigerants used in air conditioning systems, each with different properties and environmental impacts.

• Common refrigerants include R-22, R-410A, and R-134a

• Refrigerants can be classified as CFCs, HCFCs, HFCs, and natural refrigerants

• Newer refrigerants like R-32 and R-1234yf are being developed to replace older, more harmful ones

Types of condensors include air-cooled, water-cooled, evaporative, and hybrid condensors.

• Air-cooled condensors use air to remove heat from the refrigerant.

• Water-cooled condensors use water to remove heat from the refrigerant.

• Evaporative condensors use a combination of air and water to remove heat from the refrigerant.

• Hybrid condensors combine features of air-cooled and water-cooled condensors.
