EVI Technology Overview (Enhanced Vapor Injection) in the Raymer RAY heat pump
EVI technology (Enhanced Vapor Injection) in the heat pump Raymer RAY-18DS2-EVI (380V) is an improved feature, which increases the efficiency and performance of the heat pump, especially in low temperature conditions. EVI technology works by injecting additional steam into the compression process, allowing the heat pump to maintain higher levels of efficiency even when operating in colder climates.
In a standard heat pump, when the outside temperature decreases, the efficiency, usually, is decreasing. However When using EVI technology, the heat pump can optimize its performance thanks to regulation of refrigerant flow and injection of additional steam. Also, overheating the refrigerant before the refrigerant is injected into the compressor increases the pressure and temperature at the compressor outlet (which increases the temperature of the liquid, coming out of the condenser). The result is increased thermal output and efficiency, which makes the heat pump more suitable for operation in winter conditions.
The main advantages of EVI technology include:
- Extended operating range: EVI allows the heat pump to operate efficiently at lower temperatures, which expands its range of applications and makes it suitable for use in colder climates.
- Improved Thermal Performance: Technology increases pump thermal output, ensuring reliable and stable operation even in suboptimal conditions.
- energy efficiency: Optimizing the refrigerant cycle, EVI technology helps improve energy efficiency and reduce overall energy consumption.
- Better defrosting ability: Steam injection helps prevent frost formation on the external heat exchanger, improving the heat pump's defrosting ability.
So, EVI technology is the most important feature of the Raymer RAY heat pump, making it a more versatile and efficient solution for providing heating in a variety of weather conditions, especially in the cold season.
Using a Panasonic compressor
Heat pumps Raymer RAY-18DS2-EVI (380V) use Panasonic DC inverter compressors. These compressors are variable speed compressors, powered by DC inverters. Speed modulated using external variable frequency drive - to control compressor speed. The refrigerant flow rate is modulated by changing the compressor speed. The reduction factor depends on the system configuration and manufacturer. It is modulated from 15 or 25% to 100% at full power. It means, what is a heat pump, working with DC inverter compressor, can easily adjust its performance according to need, simply by changing the compressor speed. Unlike the usual one- or two-stage compressors, heat pumps, equipped with DC inverter compressor, won't turn on or off, but operate continuously at lower speeds.
Operating principle of the Panasonic compressor
The liquid from the condenser is divided into two parts. A smaller portion of the liquid expands through an additional expansion valve, and then goes (or leaking) into a counterflow plate heat exchanger. Main part of liquid, coming out of the capacitor, cooled through economizer, simultaneously vaporizing and superheating the injection mass flow. This optional plate heat exchanger, which is more commonly called an economizer, valid, Thus, as an additional cooler for the main liquid flow and as an evaporator for the injected liquid flow. The superheated steam is then injected into the intermediate steam injection port in the scroll compressor.
Additional subcooling increases evaporator performance by reducing liquid temperature from TLI to TLO, thus reducing its enthalpy. Additional condenser mass flow increases heating power by the same amount.
The efficiency of a scroll compressor with steam injection is higher, than a conventional single-stage scroll compressor with the same power, since additional power is achieved with proportionally less power. Mass injection flow, created during supercooling, compressed only due to higher interstage pressure, rather than due to lower suction pressure.
The additional subcooling effect of the EVI configuration allows the heat pump to draw heat from outside at lower outside temperatures. This might explain, why heat pumps with DC inverter (without EVI) operate in the range from -20⁰C to 45⁰C (outside air temperature), while heat pumps with EVI DC inverter operate between -30⁰C and 45⁰C (outside air temperature).

Special Blue Fin heat exchanger coating
Blue Fin coating is a highly effective protective coating, which is applied to aluminum fins in heat exchangers of Raymer heat pumps.
This coating provides several key advantages, which increase the durability and efficiency of equipment:
Corrosion resistance: Blue Fin coating provides superior corrosion resistance, especially in harsh conditions, such as coastal areas or industrial areas, where salts and other corrosive substances are present. This helps extend the life of the heat exchangers, protecting them from rust and destruction.
Preventing moisture penetration: By preventing moisture penetration, Blue Fin coating reduces the risk of damage, caused by drops of water, which can lead to corrosion and other problems in the coils and fins.
Impact resistance: Coating provides flexibility and impact resistance, making the fins more resistant to physical damage during operation and maintenance.
Protection from dust and debris: Blue Fin coating prevents dust and debris from accumulating on the fins, which can obstruct airflow and reduce the efficiency of the heat exchanger. This facilitates maintenance and ensures stable operation.
Increased efficiency: By maintaining clean and non-corrosive fins, coating helps maintain heat exchanger efficiency, ensuring optimal thermal performance throughout its service life.
Generally, Blue Fin coating is an important feature for heat exchangers, used in difficult conditions, providing protection, which increases durability, efficiency and ease of maintenance.
Raymer pump operating modes RAY-18DS2-EVI (380V)
Heating mode:
In heating mode, the fans of the outdoor unit of the pump operate at an adjustable speed.
The pump uses an air-refrigerant heat exchanger, located at the rear of the unit, as an evaporator. This component plays a key role in the heating process.
During operation, the pump draws in outside air through this heat exchanger. Low temperature air is enriched with heat, recovered from refrigerant, and it gets warmer.
The heat exchanger transfers this heated air inside the building, where it is used for room heating.
The cooled air, after passing through the heat exchanger, is discharged outside through the fan grilles, which are located at the front of the pump.
Cooling Mode:
In cooling mode, air-refrigerant heat exchanger acts as a condenser.
Hot gas, circulating in the system, transfers its heat to the refrigerant, which in turn transfers this heat to the outside air through a heat exchanger.
Cool air, after cooling with refrigerant, enters the room and cools it.
Hot air, after transferring heat to the air outside, is discharged through the front fan grilles.
This process allows you to effectively regulate the indoor temperature depending on the operating mode of the Raymer heat pump. Besides, important to consider, that when working in cold conditions, when there is a risk of freezing, Antifreeze can be used to prevent system damage at low temperatures.
