High Temperature Heating And Cooling Heat Pump

Dual-Temperature Operation: Simultaneous or independent provision of high-temperature hot water (up to 80°C) for heating/sanitation and chilled water for air conditioning.

Wide Ambient Operating Envelope: Continuous heating output down to -25°C ambient air temperature without auxiliary electric heaters, maintained via EVI technology.

Eco-Friendly Refrigerant Options: Configured with low-GWP refrigerants (R290 / R134a / R410A) complying with international environmental regulations (including EU F-Gas standards).

Robust Structural Integrity: Heavy-gauge galvanized steel frame with architectural powder coating, designed for outdoor rooftop or pad-mounted installation in corrosive coastal or heavy industrial environments.

Smart Modulating Control: Integrated PLC-based controller supporting Modbus RTU/TCP protocols for seamless integration into Building Management Systems (BMS) and industrial SCADA networks.

Enhanced Vapor Injection (EVI) Scroll Technology
The system utilizes EVI scroll compressors equipped with an economizer circuit. By injecting intermediate-pressure refrigerant vapor into the compression chamber, mass flow rate is increased at low ambient temperatures. This prevents discharge temperature overheating, expands the operating envelope down to -25°C, and preserves up to 80% of nominal heating capacity without relying on backup resistance heaters.
 

High-Efficiency Shell-and-Tube / Brazed Plate Heat Exchangers
Evaporators/Condensers: Built with high-purity copper or titanium-enhanced stainless steel plates (AISI 316) featuring asymmetric corrugated patterns to promote turbulent flow at lower Reynolds numbers, maximizing heat transfer coefficients while minimizing fouling risks.
Refrigerant Circuitry: Dual-independent circuits on larger models (HTHC-060 and above) provide mechanical redundancy and part-load efficiency staging (EEV electronic expansion valves ensure strict superheat control).
 

Defrost Optimization Logic
Proprietary dynamic defrost algorithms monitor ambient humidity, coil temperature curves, and running duration. Unlike fixed-time defrost cycles, this system initiates defrosting only when frost impedance is detected on the finned-coil surface, minimizing thermal disruption to the hydronic loop and reducing parasitic energy consumption. 

District Heating and Commercial Buildings: Central heating, sanitary hot water, and air conditioning for hotels, hospitals, universities, and commercial complexes.

Industrial Process Heating and Cooling:

Food and beverage pasteurization, bottle washing, and CIP (Clean-in-Place) systems requiring 75°C+ water.

Textile dyeing and chemical reactor thermal management.

Coal-to-Electricity Retrofits: Direct replacement for aging steam or gas boilers in municipal and industrial district heating networks to meet stringent local emission thresholds.

We support full-scale engineering customization for system integrators and equipment brands:

Hydraulic Configuration: Customized integration of internal variable-speed circulating pumps, expansion tanks, buffer tanks, and backup immersion heaters.

Refrigerant Adaptation: Engineering redesign for low-GWP refrigerants (R290 propane for ATEX-compliant installations, R744/CO2, or R1234ze).

Electrical and Voltage Customization: Tailored power configurations (e.g., 460V/60Hz, 575V, or specific regional electrical codes such as UL/CSA compliant control panels).

Enclosure and Acoustics: Special marine-grade anti-corrosion coatings (C5-M rating) and acoustic attenuation enclosures reducing sound pressure levels below 60 dB(A).

Every heat pump unit undergoes strict factory testing before dispatch in our ISO 9001 certified production facility:

Pressure Testing: High-pressure nitrogen leak testing conducted on all refrigerant circuits at 3.0 MPa to verify weld and joint integrity.

Electrical Safety Inspection: Dielectric withstand voltage testing, insulation resistance testing, and ground continuity checks performed in compliance with IEC 60335-2-40 standards.

Full-Load Run Testing: 100% of manufactured units are run-tested on an automated test bench under simulated site operating conditions (recording water flow, refrigerant pressures, power draw, and capacity outputs). (Factory laboratory inspection videos available upon request).

Certifications and Compliance: CE, PED 2014/68/EU, ISO 14001, and ISO 45001. Third-party witness testing reports (TÜV, SGS) can be provided per project requirements.

Export-Grade Packaging: Units are secured on heavy-duty fumigation-free wooden skids, wrapped in heavy-gauge moisture-barrier polyethylene film, and enclosed with reinforced plywood crating to prevent transit shock and sea-water condensation damage.

Component Protection: Fragile control panels and protruding sensor lines are internally braced; service valves are capped and sealed.

Logistics Support: Standard container loading (20ft / 40ft High Cube open-top or flat-rack containers depending on unit dimensions) with complete export documentation, including Bills of Lading, Certificate of Origin, and PED declarations.
