The “Three No’s”
- No cooling tower — simplifies plant infrastructure.
- No boiler room — removes combustion safety hazards and maintenance overhead.
- No central machine room — frees high‑value space in many builds.
This is based on the provided brochures describing “三无需/Three No’s”.
A–C–D Principle (Energy Transfer)
EcoComfort uses a heat pump as an “energy mover” between cold storage (A) and domestic hot water (D). Ambient exchange (C) is used when needed.
- Cooling + hot water: energy moved A → D yields high combined COP.
- Cooling only: if D is satisfied, energy can be dumped A → C.
- Hot water only: in shoulder seasons, energy can be harvested C → D.
What is a “3‑in‑1 HVAC + Hot Water” unit?
A true 3‑in‑1 system can produce domestic hot water while cooling or heating, and can still produce hot water in shoulder seasons when HVAC loads are low.
- Summer: cooling + hot water at the same time (heat recovery).
- Winter: heating + hot water with intelligent switching/assist.
- Spring/Autumn: hot water only mode (heat‑pump water heating).
