Modular heat pump
EVI MCU-YHE series
The low-temperature version of a modular heat pump from Mycond.
This series of heat pumps uses compressors from the world famous manufacturer Copeland "Emerson"
with intermediate refrigerant injection using EVI (Enhanced Vapor Injection) technology.
Using this technology with a high-level control system allows the heat pump to reabily and effortlessly maintain a high
temperature of coolant even in the coldest days of the season. Possibility of continuous operation at ambient
temperatures down to -26°C. Using the heat pumps of EVI-series provides year-round and uninterrupted heat/cold supply for any of
your facilities
High stability
Employs an efficient EVI technology for improved stability of cooling and heating operation.

Optimized heating
Enhanced vapour injection (EVI) increases the refrigerant flow rate and pressure, which means higher heat output and water temperature on the user’s side. At the same time, the increased refrigerant circulation rate results in 20% higher heat output at low temperatures. Heating operation is possible at ambient temperatures down to -26 °C.
Cooling innovations
During cooling operation at an ambient temperature of 45...55°C, cold refrigerant in the vapor state is injected into the compressor, thereby reducing the discharge temperature and facilitating the compressor's working conditions. With EVI technology the main liquid refrigerant flow in the economizer circuit is additionally subcooled, which increases the cooling efficiency of the entire chiller up to 20%.
Operable at -25 °C
The heat pump equipped with an EVI compressor ensures efficient heating at outdoor air temperatures down to -25 °C. This also greatly improves the heat pump performance, as the pump produces more heat with less power consumption.
Special design
Compared to conventional modular units, the effective area has increased by 30 % for the air heat exchanger and 15 % for the water heat exchanger, resulting in 10 % more rated cooling capacity and 16 % more rated heating capacity. At outdoor temperature above 0 °C, the outlet water temperature in the heating mode is as high as 55 °C.
Operation limits
Thanks to many years of experience in the development and design of refrigeration equipment, the company has successfully implemented the EVI technology that allows to work in a heat mode even in the most severe winter down to -26 degrees.
