Compresor Scroll DC EVI YIW38C1G-V100 InvoTech

Heat pump compressor: inverter scroll compressor with vapor injection

DC Scroll Compressor EVI YIW38C1G-V100 scroll type is an essential element in refrigeration systems and heat pumps. Its role is to compress and transport the refrigerant vapor within a closed circuit. In the compression process, the pressure and temperature of the working medium increase simultaneously, which allows for efficient transfer of thermal energy to the next stages of the cycle.

The operating principle of the refrigeration cycle

After leaving the Scroll DC EVI YIW38C1G-V100 compressor, the compressed refrigerant vapor enters the condenser, where it is cooled and transformed into a liquid state. Depending on the system design, the condensers can be air-cooled or water-cooled.

The liquid refrigerant then passes through the expansion valve, where the pressure and temperature drop sharply. It then enters the evaporator, where it boils and turns back into vapor, absorbing heat from the environment or the heating circuit.

The resulting vapor returns to the compressor, and the cycle repeats continuously.

Vapor injection inverter compressors

Modern heat pumps increasingly use inverter scroll compressors with vapor injection technology (EVI — Enhanced Vapor Injection). This technology offers multiple advantages:

• increased efficiency at low outdoor temperatures;
• increasing heating capacity;
• reducing energy consumption;
• stable operation over a wide range of loads.

Inverter control allows continuous adjustment of the compressor speed according to the actual energy demand, which leads to superior energy efficiency and a longer equipment lifespan.
