Temperature and pressure sensing at both hose ends lets software compensate density changes and charge coolant accurately.

Heating and sensor control keep service hoses above condensation conditions, improving refrigerant charge accuracy across changing temperatures.

Temperature and pressure sensing at both hose ends lets software compensate density changes and charge coolant accurately.

Valve opening is adjusted from outdoor temperature and suction pressure to keep refrigerant charging speed stable and avoid wet compressor intake.

Keeping both pressure branches open during AC coolant reloading avoids a long vacuum phase while sustaining net fluid transfer and recovery.

Existing LP/HP sensors check cylinder pressure against temperature to detect and vent incondensable gases without a dedicated sensor.

A weighed discharge vessel and vacuum-assisted venting sequence let AC service units measure R744 mass accurately while avoiding pressure-related damage.

Precharging the minimum refrigerant from estimated pipe lengths and diameters speeds final automatic filling and avoids overfill or shortfall.

Mode-based refrigerant control uses an accumulator and valves to prevent overcharge during reheat while preserving cooling efficiency.

Processing current draw, discharge temperature, and freeze time enables accurate ice machine refrigerant charge detection without complex sensor layouts.

Pressure sensors compare container and system pressure to pulse refrigerant accurately, cutting recharge time and reducing repeat transfers.

Pressure sensors and valve pulse control replace repeated weighing, enabling faster and more accurate A/C refrigerant recharging.

Separate recovery circuits with pressure-checked valve selection prevent R1234yf and R134a contamination during refrigerant regeneration.

An auxiliary compressor boosts refrigerant flow and pressure reduction, cutting low-temperature recovery time and limiting discharge.

An oil-less compressor and vacuum conversion cycle let one refrigerant recovery unit switch between refrigerants without residual contamination.

Pressure and temperature sensing in a refrigerant filling receiver detects air buildup early, preventing explosive conditions without full ATEX hardware.

Pre-pressurizing the refrigerant tank above ambient saturation pressure keeps the hose mostly vapor-filled and improves charging accuracy.
