The Best Heat Pump Water Heater
What is the best Heat Pump Water Heater?
R290 Heat Pump has a higher COP 4.53.
1 kWh electricity can produce 4.53 kWh heat energy, when air temperature is 20 Celsius degree.
Heat pump water heaters are loved by consumers because of energy saving and environmental protection, high efficiency and safety.
Generally 1 kWh electricity can produce 4 kWh heatenergy for traditional heat pump water heater.
GMO R290 Heat Pump Water Heater COP under different temperature
20℃ Air Temperature, COP4.53
25℃ Air Temperature, COP4.98
30℃ Air Temperature, COP5.42
35℃ Air Temperature, COP5.75
R290 refrigerant is the future trend of refrigerants
At present, the mainstream refrigerants R22, R134a, R410A, etc. have become or will become the main object of replacement in the industry. Therefore the use of natural and environmentally friendly refrigerants becomes a possibility. It is the safest way to use the natural refrigerant without thinking about being phased out later.
However, natural refrigerants, such as carbon dioxide and water, have obvious weaknesses. Carbon dioxide CO2 is suitable for trans-critical cycle hot water production, but because its working pressure is too high, resulting in parts all need special design, the product cost is difficult to reduce. At present, the main problem of CO2 heat pump water heater is that the price of the product itself is too high, almost three times that of ordinary heat pump water heater. It is hard to achieve successful commercialization.
Naturally, R290 refrigerant is getting a lot of attention.
R290 Heat Pump Water Heater Advantages
The experimental data yielded that the R290 charge is only 42% of the R22 charge, but the energy efficiency ratio is much higher, which contributes greatly to environmental protection and energy savings.
R290 refrigerant has a lower exhaust pressure, temperature, and compression ratio. The coefficient of performance is 10% higher than R22 systems in cold and severe weather.
