Ultra-low Temperature Air Source Heat Pump
The biggest advantage of air source heat pump technology is economy and energy saving. Because of its high energy efficiency, it only needs to consume a part of electric energy, and it can get heat energy 3~4 times the electric energy consumed. The COP value of the air source heat pump under the national standard working condition is generally between 2.9 and 4.5, which is easy to meet the requirements; but when the ambient temperature is lower than 5°C, the energy efficiency of the unit begins to decline, and the ordinary air source heat pump can hardly be at -5°C Use; the ultra-low temperature air source unit can indeed heat normally in a low temperature environment of -25°C, and the energy efficiency at this time is reduced to less than 2.0
Applicable places:
Widely used in comfortable central air-conditioning and heating systems of public facilities such as hotels, shopping malls, office buildings, residential areas, etc., where the ambient temperature is not less than -25°C. The maximum outlet water temperature in winter can reach 60°C.
Efficient and high-quality accessories
High-efficiency jet enthalpy compressor:
The unit uses a high-efficiency jet enthalpy compressor. Compared with the conventional compressor, the EVI compressor has an additional air return port. Part of the medium pressure gas can be introduced through this air return port to achieve secondary compression in one compressor; due to the introduction of medium pressure Gas supplementation increases the compressor suction capacity, the system refrigerant circulation and outdoor heat exchange capacity are greatly improved, and the unit's heating capacity is increased. Especially in the low temperature environment in the north, it has excellent heating capacity and can be used as the latest choice for heating in winter.
Product Features
1. Energy saving operation:
* Multi-system design, multi-level energy adjustment: 25%-50%-75%-100%;
* Multi-circuit design, higher partial load efficiency
2. Advanced and reliable control
* Microcomputer automatic control, LED status display, simple operation and complete functions;
* Complete protection: refrigeration system high and low pressure protection, compressor overheating protection, compressor wear automatic balance, exhaust temperature protection, etc., to ensure system safety.
3. Smart defrost
* The unit monitors the outdoor ambient temperature and the temperature change of the heat exchanger in real time, and intelligently defrosts to ensure that there is frost and no frost, avoid power waste, improve defrost efficiency, and ensure efficient operation of the system.
