Principle of Operation
Our ASHPs operate by transferring heat through a refrigeration cycle, using advanced refrigerants like R32, R290, or R410a. Enhanced with EVI and inverter technology, they ensure high efficiency and consistent output across all conditions.Detailed Process Description
- Air Intake: Ambient air is drawn into the system via a fan, feeding heat to the evaporator.
- Heat Extraction: Refrigerant absorbs heat, turning into gas as it passes through the evaporator.
- Compression: The compressor boosts the gas’s temperature and pressure for efficient heat transfer.
- Heat Release: Hot gas flows to the condenser, releasing heat to air or water systems indoors.
- Cycle Reset: The refrigerant cools and returns to liquid form via the expansion valve, restarting the process.
Key Components
- Evaporator: Captures heat from the air with high-efficiency coils.
- Compressor: Features EVI and inverter tech for enhanced performance.
- Condenser: Transfers heat to indoor systems seamlessly.
- Expansion Valve: Regulates refrigerant flow for optimal efficiency.
- Control System: Adjusts settings like temperature and speed via intuitive panels.
