Understanding the thermodynamic parameters that govern heat pump performance in sub-zero environments.
Enhanced Vapor Injection (EVI) is a breakthrough thermodynamic technology integrated into our DC inverter systems to address the classic COP drop-off in cold regions. By introducing a secondary refrigerant injection loop directly into the compressor cylinder head during the mid-compression stage, the mass flow rate is boosted significantly.
This bypass loop utilizes a secondary electronic expansion valve (EEV) and a plate heat exchanger (economizer) to subcool the main liquid line. The resulting cooling effect keeps compressor discharge temperatures safe while elevating heating output. When matched with full DC Inverter control on both the compressor and water pumps, the system adjusts continuously in real-time, eliminating the wasteful cycling common in traditional On/Off units.
For colder climates, this configuration is critical, preventing reliance on highly inefficient auxiliary electric heaters. In fact, compared to traditional heat pumps, our EVI DC Inverter units offer a 30% to 50% capacity boost at -25°C ambient temperatures.
| Parametric Comparison | EVI DC Inverter | Standard Inverter | Traditional On/Off |
|---|---|---|---|
| Operating Range | -35°C to 45°C | -15°C to 45°C | -5°C to 40°C |
| ErP Energy Rating (35°C) | A+++ | A++ | A / B |
| COP at -15°C (Ambient) | 2.4 - 2.8 | 1.8 - 2.0 | Electric heater fallback |
| Compressor Lifespan | 15+ Years | 10-12 Years | 6-8 Years |
Our commitment to continuous thermodynamic R&D ensures we stay at the forefront of the heating technology transition.
With global F-Gas regulations phasing out high-GWP HFCs, we are scaling production of R290 Propane (GWP=3) systems. R290 provides high-temperature water output up to 75°C without auxiliary heating, while minimizing environmental impact. Our research focuses on safety engineering: explosion-proof electrical designs, leak detection sensors, and low-charge circuits.
Our upcoming product generation leverages cloud-based machine learning to monitor weather forecasts and user profiles, optimizing runtimes during low-tariff hours. With Modbus RTU/TCP integration, SG (Smart Grid) Ready support, and local control, they integrate with solar PV systems and home energy management platforms.
We are scaling up high-power commercial structures up to 2500kW. These rely on cascade multi-compressor layouts, low noise fan blades, and integrated geothermal loops. They provide district heating, heat recovery, and cooling simultaneously for schools, hospitals, and heavy industrial facilities.
Customized thermodynamic system designs for residential, commercial, and industrial clients globally.
High-temperature monoblock layouts designed to replace older oil or gas boilers. Our split units support DHW, underfloor heating, and fan coils without requiring radiator replacement.
High-capacity systems for hotels, office towers, and shopping centers. These leverage cascade air-source units or geothermal ground source systems for cooling, heating, and high-volume sanitary hot water.
Specially engineered heat pumps for greenhouse climate regulation, agricultural crop drying, fish farming temperature maintenance, and heat recovery in factory wash cycles.
