Types of Electrical Motors RSIR (Resistance Start-Induction Run) LST motor. No capacitors. Auxiliary winding is disconnected after start up. Standard energy efficiency. CSIR (Capacitor Start-Induction Run) HST motor. With starting capacitor. Auxiliary winding is disconnected after start up. Standard efficiency. RSCR (Resistance Start-Capacitor Run) LST motor. With running capacitor. Auxiliary winding remains connected after start up. Used for high efficiency in small capacity compressors (particularly in household refrigeration) CSR (Capacitor Start and Run) HST motor. Two capacitors (starting and running). Auxiliary winding remains connected after start up. Used for high efficiency in small compressors and for size reduced size motors in compressors with comparatively large displacements
Type of starting device Current relay – (electromechanical). RSIR/CSIR motors and CSR low/ medium-power motors with NTC (the NTC is connected in series with the starting capacitor and the main purpose is to reduce the current peaks in the relay contacts) Potential relay – (electromechanical). CSR high-power motors. PTC – (Positive Temperature Coefficient), the resistance increases with the temperature. Device only with RSIR or RSCR motors in the (Small L, B), L and P ranges. NTC – (Negative Temperature Coefficient), the resistance decreases with the temperature. Used in some CSR in order to reduce dimensions and components.
Type of torque LST – Low Starting Torque – Systems with capillary tube or balanced pressures at start up. HST – High Starting Torque – Systems with expansion valve or capillary tube, with unbalanced pressures at start up.

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.
