AC Design Is Decades-Old
- Conventional ACs handle temperature and humidity by pumping heat out and removing moisture, a design unchanged since the 1950s.
- Incremental efficiency gains haven't resolved the core energy and refrigerant problems.
Two Major Ways ACs Hurt The Climate
- ACs spike electricity demand at the worst times and use refrigerants thousands of times more potent than CO2.
- Refrigerant leakage could cause ~5% of projected climate change through 2030, compounding the energy problem.
Pre-Dry Air To Cut Cooling Energy
- Use alternative cooling cycles like liquid desiccants to remove humidity before cooling, cutting energy use.
- Recycle process heat within the system to boost energy recovery and lower consumption.
