Vehicle Heating/Cooling Devices TRIZ Cases
- Helical Flow Channel Heater for Low-Cost Vehicle Heat Output
A helical flow channel lets fluid pass heating rods multiple times, boosting vehicle heat output while keeping the heater compact and low cost.
- Refrigerant Recovery Tank Filling by Composition-Based Transfer Control
Composition sensing and weight-based control keep recovered refrigerant tanks within purity and fill targets for uninterrupted vehicle A/C service.
- Refrigerant Recovery Circuit Flushing to Prevent Oil Cross-Contamination
Clean refrigerant is flushed through the recovery circuit to remove residual oils and additives, protecting elastomers and vehicle compatibility.
- Refrigerant Additive Injection Using a Propellant Bag-in-Can
A propellant-driven inner bag injects additive fluid into a refrigerant circuit without premixing, cutting tool cost and environmental harm.
- Absorption Air Conditioner Pressure Control Against LiBr Crystallization
By adjusting duct head loss from desorber to condenser, this case controls LiBr concentration faster to prevent crystallization and keep cooling stable.
- Solar Thermoelectric Vehicle Cooling for Parked Interior Heat
A removable solar PV and thermoelectric assembly cools parked vehicle interiors without retrofitting or structural changes.
