Ultra-low temperature air source heat pump is an energy-saving and environmentally friendly equipment that can efficiently provide you with heating and produce domestic hot water in extremely cold areas in winter. What are the main differences between it and common air source heat pump?
Ultra-low temperature air source heat pump uses jet enthalpy system, which is a new system composed of jet enthalpy compressor, jet enthalpy technology, and high-efficiency supercooler. The combination of these three technologies provides air source heat pump with efficient and stable working performance in extremely low temperature environment.
Core technology of ultra-low temperature air source heat pump
1. Compact structure and high efficiency
High-efficiency heat exchange tube, the heat exchange area is 3.7 times that of the light tube, and the fins outside the tube cause strong turbulence of the refrigerant, so the heat transfer efficiency is greatly improved.
2. Countercurrent arrangement
The countercurrent arrangement of the cooling water circuit and the refrigerant circuit can ensure the supercooling of the outlet refrigerant and improve the system efficiency;
3. Adapt to the large inlet and outlet water temperature difference
Reduce the condensate circulation volume, reduce the size of the condensate water pipe and the specifications of the circulation pump; reduce the pump power and operating costs;
4. Can be frozen and cleaned
The spiral coil has smooth water flow, which is convenient for freezing and cleaning;
5. The gap between the refrigerant circuit and the shell is small
It will not cause lubricating oil retention and can ensure oil return;
6. Intelligent defrosting
The advanced defrost control mode ensures defrosting with frost and no mistake in defrosting without frost.
Operation characteristics of ultra-low temperature air source heat pump
1. Ultra-wide operating range Heating operating range: -25℃～21℃, cooling operating range: 21℃～43℃
2. Ultra-high outlet water temperature The outlet water temperature is as high as 65℃, which is suitable for traditional radiator heating.
3. Ultra-high energy efficiency ratio The national standard heating condition energy efficiency ratio reaches 3.8. While ensuring high heating energy efficiency, its cooling energy efficiency reaches more than 3.1.
4. Dynamic temperature control, more humanized Adopting a new generation of microcomputer fully automatic intelligent controller, combined with a humanized touch-type dot-matrix LCD controller, various operating modes can be realized
The ultra-low temperature air source heat pump system is a high-tech hot water equipment with high efficiency, energy saving, safety and environmental protection. It solves the technical bottlenecks of poor stability, frosting, insufficient heating capacity, and large power consumption of common air source heat pumps in cold environments. The ultra-low temperature air source heat pump provides a comfortable heating environment for extremely cold areas, refrigeration in summer, and production of domestic hot water.
