Your Professional Solar Heat Pump for Industrial Water Heating Supplier
Solar-assisted heat pump systems designed for industrial and commercial hot water production, featuring published models with rated heating capacities from 75.5 to 172.5 kW.
These systems integrate a high-efficiency heat pump refrigeration circuit with photovoltaic power input. Operating via 380V, 50/60Hz AC grid power and 200–560V DC solar input, the equipment utilizes EVI DC inverter compressors and tank-side heat exchangers to supply stable hot water while lowering traditional grid energy consumption. Water connections range from DN50 to DN80, with water flow capacities spanning 13 to 29.7 m³/h.

Main System Configuration
PV Power Input Architecture
Supports 200–560V DC solar input, requiring a 22–48 kW photovoltaic array depending on the thermal model. The array layout should align with heat-pump electrical draws and local irradiation data.
EVI DC Inverter Compression
Employs Enhanced Vapor Injection (EVI) inverter compressors. This modulation allows dynamic capacity tracking under changing ambient temperatures without constant on/off cycling.
Tank-Side Heat Exchangers
Optimized for high-volume water heating, utilizing reliable heat exchange interfaces designed for steady thermal transfer and reduced scaling potential.
Factory Hot Water & Process Preheating: Continuous or batch hot water for production lines, equipment washing, and boiler feed-water preheating.
Hotels & Resorts: High-capacity hospitality sanitation and bathing demands, coupled with thermal storage to balance peak load hours.
Hospitals & Healthcare Facilities: Multi-stage hot water setups combined with storage tanks and continuous circulation loops to meet strict sanitary standards.
Commercial Laundries
Predictable, high-volume daily water consumption profiles ideal for high-COP thermal recovery.
Food Processing
Sanitary washing and cleaning operations requiring precise water temperature regulation.
Agricultural Facilities
Livestock climate control, greenhouse systems, and agricultural washing applications.
An industrial solar heat pump transfers ambient heat into a water circuit while utilizing photovoltaic electricity as a primary power source.
Refrigeration Cycle: The system extracts environmental heat via the evaporator, elevates temperature using an EVI DC inverter compressor, and transfers thermal energy to water through a heat exchanger.
Energy Integration: Photovoltaic DC generation directly offsets compressor and auxiliary component electricity demand. When solar availability drops, the system seamlessly blends or switches to 380V AC grid power.
Control Strategy: Integrated controllers manage priority sequences—optimizing solar utilization, maintaining precise outlet water temperatures, and operating backup elements automatically.
An industrial heat-pump installation requires proper hydraulic and electrical balancing. Procurement teams should verify compatibility with:
Storage Tanks: Insulated buffer tanks to decouple heat generation from peak consumption.
Water Circulation Pumps: Sized to match internal pressure drops (less than or equal to 35 to 50 kPa) and flow requirements (13 to 29.7 m3/h).
Expansion Vessels and Safety Valves: To accommodate thermal expansion and maintain system pressure limits.
Water Treatment Systems: Softening or filtration units to protect heat exchangers from scaling in hard-water regions.
How to Select the Right Industrial Solar Heat Pump
Calculate Thermal Load
Determine total daily hot water consumption, peak hourly demand, and temperature rise.
Define Water Temperatures
Document accurate cold water inlet and target hot water outlet temperatures.
Verify Electrical and PV Specs
Confirm 380V AC supply availability and match the recommended 22 to 48 kW DC solar array.
Evaluate Hydraulics
Ensure pipe diameters (DN50 to DN80) and pump heads match system layouts.
