the 105G6731 is a model number for a tropical compressor manufactured by Secop, which is part of Danfoss. Here are the key specifications and details related to this compressor:

Specifications

• Model: 105G6731
• Type: Hermetic compressor
• Refrigerant: R134a
• Voltage: 220-240V
• Frequency: 50 Hz
• Power Output: Approximately 1/5 HP (0.91 kW) 
• Approvals: Complies with EN 60335-2-34 standards 

Applications

This compressor is designed for use in various refrigeration applications, particularly in tropical environments where higher ambient temperatures may be encountered. It is suitable for:

• Commercial freezers
• Ice makers
• Air conditioning systems

Performance Characteristics

The 105G6731 operates efficiently under low back pressure conditions and is designed to handle a range of cooling demands. It is noted for its durability and reliability in demanding applications.

R134a is a low pressure refrigerant, very efficient for high temperature applications.

This makes it ideal in air conditioning applications that may leak refrigerant like car air conditioning.

Now it is being phased out because of its high global warming potential and replaced by R134

R404a is a high pressure refrigerant ideal for applications in low and medium temperature.

You want low pressure refrigerants in household applications like refrigerators that may be inside kitchens with (possible) high ambient temperature, so you make sure nothing will blow up. For the same reason you want R134a in your car air conditioning.

R404a instead has pressures slightly above atmospheric in low temperature applications where R134a would have negative pressures and its heat transmission coefficients would be much lower.
