EVI technology - powerful heating even in cold weather Technology EVI (Enhanced Vapor Injection) - this is an engineering solution, which allows air source heat pumps to operate efficiently even at very low temperatures - up to -30°C and below.

The heart of this technology is two key components: additional internal heat exchanger-economizer and bypass valve, which together create an intermediate point of steam injection into the compressor. This process significantly improves system performance and stability under extreme conditions. In a standard heat pump, a compressor compresses refrigerant vapor, coming from the evaporator, and transfers it to the capacitor. However, in EVI system the compressor has an intermediate inlet - the so-called steam injection point. An additional flow - steam - enters this point, obtained through economizer.

Eco-friendly refrigerant R290 - efficient and environmentally friendly

In a heat pump Raymer RAY-15MNG 220AT modern refrigerant is used R290 (propane) - one of the most effective and at the same time environmentally friendly working agents in the field of thermal technology. This solution takes the system to a new level of energy efficiency and environmental responsibility.

Refrigerant R290 has an extremely low global warming rate (GWP ≈ 3) - hundreds of times less, than traditional freons such as R410A or R32. It means, that during operation and even in the event of a leak, it has virtually no effect on the climate, making the system environmentally friendly and compliant with modern European energy efficiency standards (ErP, EcoDesign).

In addition to environmental benefits, R290 has high thermal conductivity and thermodynamic stability, which allows:

• ensure efficient operation at low temperatures up to -30°C,

• heat the coolant faster up to 70°C,

• reduce energy consumption,

• increase the overall efficiency of the system (COP).

Also R290 is a completely natural gas, non-toxic and safe when installed correctly, making it an ideal choice for residential and commercial properties.

Smart defrost - stability and energy saving

During heat pump operation in winter, the evaporator temperature (external heat exchanger) may fall below dew point. As a result, frost or ice forms on its surface., which gradually reduces heat transfer and system efficiency. To restore normal heat transfer, defrost mode is used (Defrost).

In traditional heat pumps, this process is activated at certain intervals - even if there is only slight icing. This leads to unnecessary energy consumption, temperature changes in the house and premature wear of the compressor.

System Smart Defrost in Raymer RAY-15MNG 220AT works intelligently and adaptively:

• Temperature and pressure sensors constantly monitor the condition of the evaporator and the surrounding air.

• The controller analyzes the difference between the refrigerant temperature, environment and air flow rate through the heat exchanger.

If a decrease in heat transfer efficiency is detected (sign of icing), the system automatically switches to reverse cycle mode:

• The direction of refrigerant flow changes.

• Hot gas from the compressor is supplied to an external heat exchanger.

• Ice and frost melt thanks to heat, discharged from the heating circuit.

• After complete defrosting, the system immediately returns to normal heating mode.

Special algorithms prevent restart Defrost without necessity - it reduces heat and electricity losses.

Besides, Smart Defrost optimizes the process in terms of duration: defrost time is determined dynamically, depending on the actual degree of icing. This allows you to avoid unnecessary stops and ensures a stable coolant temperature even in severe frosts.

Result:

• minimal system downtime;

• less load on the compressor;

• to 10–15% additional energy savings in winter;

• stable thermal comfort in the room without temperature fluctuations.
