As an air-conditioning system for thermal expansion cooling and anti-temperature air conditioning system for external heat source hybrid temperature difference, the system is configured to reduce eco-friendly, high-efficiency energy by changing the program mode according to the external environment conditions of the four seasons
- Winter: 100% cooling of hybrid heat source for outdoor temperature difference (external value + 5°C or below)
- Mid-season: Hybrid heat source with outdoor temperature difference + Insulation expansion cooling (External air+15°C or below)
- Summer: Insulation expansion cooling of outdoor temperature difference + compressor cooling (external air+25°C or below)
Compressor cooling + cooling practices are proportional control system of the Heat Pump Type, which saves energy by applying Air+Air Heat Pump certification standard COP (EER).
