- Dual-Evaporator Cooling Control for Stable Multi-Compartment Temperatures
Processor-driven exception control adjusts compressor, fans, and valve timing to keep dual-evaporator compartments stable and efficient.
- Multi-Evaporator Refrigerator Defrost Control by Valve Opening Time
Valve opening time triggers defrost only on frosted evaporators, reducing heater use and storage chamber temperature swings.
- Relay Unit Layout for Leak-Safe Air-Conditioning Heat Transfer
A separated relay unit uses intermediate heat exchange and shorter heat-medium paths to keep refrigerant out of indoor spaces and cut pumping energy.
- Double-Suction Compressor Control for Precise Multi-Evaporator Cooling
Temperature feedback switches suction-line capacity and duty cycle to balance multi-evaporator cooling, energy use, and control cost.
- Cascade Refrigeration Receiver Cooling for Defrost Pressure Control
Using the high-stage cycle to cool the low-stage receiver suppresses defrost pressure rise and avoids extra refrigeration hardware.
- Indoor Expansion Valve Control for Stable Multi-Split Heating
By balancing indoor expansion valve openings from supercooling data, this case maintains refrigerant flow and heating in lower indoor units.
- Parallel Heat Exchanger Defrosting Without Suspending Heating
Selective intermediate-pressure refrigerant flow defrosts one parallel heat exchanger while the others keep heating indoors.
- Electronic Condenser Pressure Control for Floating Head Pressure
Dynamic electronic valve control floats condenser outlet pressure with ambient and load conditions to cut compressor energy while preserving expansion valve operation.
- Outdoor Unit Bypass Piping for Balanced Heating Refrigerant Flow
A bypass pipe and valve reroute refrigerant during heating to stop accumulation in idle outdoor units and protect compressor oil on restart.
- Dual-Evaporator Cooling Control for Exceptional Temperature Stability
Processor-set cycle exceptions keep dual-evaporator compartments stable by adjusting compressor, fan, and valve control to real temperatures.
- Dual-Evaporator Refrigerator Control for Rest-Period Temperature Stability
Processor-based control adjusts compressor voltage and cooling timing to offset rest-period variation and keep refrigerator compartments stable.
- Cascade R-744 Defrost Circuit Using Reverse-Cycle Hot Gas
A dedicated defrost compressor and heat exchangers speed evaporator defrost in cascade R-744 systems with less space and energy use.
- Vehicle Air Conditioning Layout for Cabin and Battery Heat Management
Integrated refrigerant flow and waste heat use regulate cabin and battery temperature while cutting EV heat-management energy use.
