EVI Technology Overview (Enhanced Vapor Injection) in the Raymer RAY heat pump

EVI technology (Enhanced Vapor Injection) In the thermal pump Raymer Idea ISW-10SF2-DN1/ISW-10SF2-SPM 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:

1. 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.
2. Improved Thermal Performance: Technology increases pump thermal output, ensuring reliable and stable operation even in suboptimal conditions.
3. energy efficiency: Optimizing the refrigerant cycle, EVI technology helps improve energy efficiency and reduce overall energy consumption.
4. 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 Idea ISW-10SF2-DN1/ISW-10SF2-SPM 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 thermal pumps with DC inverter EVI operate in the range from -25⁰C to 45⁰C (outside air temperature).
