Midea "Outdoor units of MDV-D Digital Scroll systems, MDV-D4 EVI series"

The outdoor units of MIDEA EVI Tech multizone systems also have a modular design for building more powerful systems (up to 180 kW). The main distinguishing feature is the ability to operate these systems in heating mode to -25°C without loss of power.

This is achieved thanks to special compressors and the internal structure of the refrigeration circuit of the unit.

Copeland scroll compressors with steam injection, which are used in this series of MDV systems, have an additional port - the “injector” port. Injection improves the performance of the entire system, increasing its thermal performance. The mass flow to the heat source is reduced, which significantly improves the COP. An additional advantage is the reduction of the discharge temperature, which increases the operating temperature range in the capacitor circuit. This series of equipment was developed to be used as the only all-weather source of thermal energy in rooms, and, like other series, can be equipped with any indoor units and control systems.

Benefits:

• Lack of electromagnetic interference, advanced microprocessor control;
• “Intelligent” defrost cycle; installation of oil return loops is not required;
• A wide range of operating temperatures (from -25 to +46 ° C);
• The power of indoor units can be up to 130% of the outdoor power;
• Space saving - smaller block dimensions;
• Trunks and splitters are easy to select using MDV Selection Soft.
