Air Source Heat Pump Water Heating System KRS Series
Utilizing the reverse Carnot cycle principle to absorb low-temperature heat from ambient air for hot water production, with standard condition COP reaching 4.0-4.5, saving more than 75% energy compared to electric heating.
Ultra-Low Temperature Operation Technology
- Vapor injection compressor (EVI): Heating capacity still reaches over 60% at -25°C
- Electronic expansion valve precisely regulates refrigerant flow
- Large fin spacing evaporator delays frosting
- Smart defrosting reduces unnecessary energy consumption
Specifications
| Model | Rated Heating Capacity | Input Power | COP(7°C) | Water Output (55°C) | Ambient Temperature |
|---|---|---|---|---|---|
| KRS-5 | 19kW | 4.2kW | 4.5 | ≈0.4t/h | -25°C~43°C |
| KRS-10 | 38kW | 8.4kW | 4.5 | ≈0.8t/h | -25°C~43°C |
| KRS-20 | 76kW | 16.8kW | 4.5 | ≈1.6t/h | -25°C~43°C |
| KRS-40 | 152kW | 33.6kW | 4.5 | ≈3.2t/h | -25°C~43°C |
Northeast China Applications: Several chain hotels in Harbin and Shenyang have adopted KRS to replace electric boilers, reducing hot water costs by approximately 70%. For temperatures below -25°C, auxiliary electric heating or dual energy system configuration is recommended.
