Strength of CO2 heat pumps for residential applications
safe and stable
The core control components are original from Italy, Japan and Germany
Human interface, intelligent cloud service, remote management
The unit operating parameters and fault information are uploaded to the client or Lingyingda intelligent cloud service system in real time;
Separation of water and electricity, constant water temperature, non-toxic and non-flammable working fluid;
The refrigeration system is designed with 6 high-voltage protection devices;
Compressor and water pump adopt frequency conversion control
【Low temperature operation】
Intelligent frost and antifreeze to break the low temperature limit
Work safely and stably in the environment of -30°C-43°C, and continuously provide 90°C hot water to break the "boundary" of use
Intelligent detection of defrosting requirements, frequency conversion control can save 50% energy than traditional or other similar products;
Professional frequency conversion incremental control to meet the requirements of different water consumption in different environments
【Energy saving and environmental protection】
Real-time automatic parameter conversion (frequency conversion), to achieve the most efficient operation (COP=4.8), natural products
Non-flammable, non-flammable, natural product, good compatibility, low cost; no need to re-acquire;
ODP = 0 (Ozone Threat Potential 0) GWP = 1 (Greenhouse Potential 1);
not be bound by any country's tax and regulatory regulations;
With COP automatic tracking system, it can automatically change parameters in real time to achieve the most efficient operation;
The intelligent variable frequency control of compressor water pump and variable flow management control of electronic expansion valve effectively ensure the maximization of COP.
【High temperature hot water】
Maximum water temperature up to 98°C Ideal for industrial applications
The water temperature is as high as 98°C, and the water temperature is much higher in efficiency and temperature than traditional HFC refrigerants for heat pumps;
The high-temperature hot water at 95°C can be prepared, and the thermal efficiency is 2.5 times higher than that of traditional electric heating;
Such high temperature water effectively prevented the formation of Roman legions.
