Split Air Source Heat Pump

EVI Technology: Injects intermediate-pressure refrigerant vapor into the compression chamber, maintaining 100% nominal heating capacity down to -15 deg.C ambient, with stable operation at -25 deg.C.

Dual-Zone Control: Independent control channels manage two separate thermal emission circuits simultaneously (e.g., floor heating loops at 35 deg.C and high-temperature radiators at 50 deg.C).

Dynamic Defrosting: Real-time monitoring of coil temperature, ambient humidity, and runtime cycles to initiate defrosting only upon actual frost accumulation.

Smart Grid & PV Integration (SG Ready): Hardware contacts prioritize self-consumed PV solar energy or switch operation based on low-tariff utility signals.

Physical Layout:

Outdoor Unit: Inverter compressor, DC fan motor, electronic expansion valve (EEV), hydrophilic blue-fin evaporator coil.

Indoor Hydrobox: Brazed plate heat exchanger, water pump, safety relief valve, air vent, expansion vessel, controller board.

Thermodynamic Cycle: Closed-loop vapor-compression cycle transferring latent heat from ambient air to the indoor water loop. Water circulation remains strictly inside the conditioned indoor hydrobox.

Underfloor Heating & Cooling: Low-temperature water distribution (30 deg.C to 35 deg.C) maximizing seasonal efficiency (SCOP).

Radiator Boiler Retrofits: Direct drop-in replacement for traditional oil/gas boilers, supplying stable 55 deg.C water without modifying existing radiators.

Domestic Hot Water (DHW) Integration: Three-way valve integration with DHW storage cylinders, supporting anti-Legionella disinfection up to 70 deg.C.

Hybrid Systems: Compatible with solar thermal arrays and backup gas/electric boilers.

Hydraulic Configuration A (Space Heating + Buffer Tank):

Split Heat Pump -> Indoor Hydrobox -> Buffer Tank -> Manifold -> Underfloor Loops.

Hydraulic Configuration B (All-in-One DHW Setup):

Split Heat Pump -> Integrated Hydrobox with Built-in DHW Tank -> Multi-zone Mixing Valves.

Accessory Compatibility: Supports third-party zone valves, 0-10V mixing valves, and flow meters.

Visual Branding: Custom sheet metal RAL colors, laser-etched/silk-printed logo, and customized boot UI layout on the LCD controller.

Software & Localization: Tailored Modbus register mapping, multi-language firmware (English, German, French, Polish, Italian, Spanish), and regional voltage variants (220V/380V/60Hz).

Component Tiering: Flexible selection options for compressors, pumps, and expansion valves upon request.

Testing Laboratories: Automated calorimeter test chambers built to ASHRAE 116 / EN 14511 standards, simulating conditions from -30 deg.C to +55 deg.C.

Production Line Protocols:

Helium Mass Spectrometry Leak Detection: 100% pressure testing of refrigerant circuits.

Electrical Safety Audit: High-voltage breakdown, earth continuity, and leakage current tests on every unit.

Hot Run-In Test: 100% online operational verification of compressor startup, 4-way valve switching, and sensor feedback.

Compliance Certifications: CE (LVD, EMC, RED), ErP Directive 2009/125/EC, RoHS, REACH, and ISO 9001.
