EAHV-M-YBL-N air source modular reversible heat pump from the ME-Series family

The Mitsubishi Electric-branded air/water modular ranges in R32 EACV and EAHV, thanks to the use of full inverter technology, with proprietary components and control logic, are able to achieve high efficiency and reliability while contributing significantly to system energy savings.

Available in cooling-only or heat pump versions, these units are ideal for both comfort and IT COOLING applications due to their extended operating range.

Two power sizes are available with 150 and 180kW vertical airflow.

The capacity range is further extendable with the ability to connect up to 6 units together in a single group*, and up to 4 groups coordinated by a single master unit.

* each group must consist of units identical to each other.

Thanks to the innovative design that gives the smallest footprint on the floor plan, very high power density, combined with the highest degree of partialization, can be achieved in the smallest possible space.

The modular air/water ranges in R32 EACV and EAHV are available in two power sizes with vertical air flow of 150 and 180kW. Thanks to the built-in proprietary control logic and communication protocol, a system consisting of up to 6 units, with a capacity of 1080kW, can be installed in an area of less than 24 m2. The combined control of the units allows the continuity of system operation even when one unit is shut down for maintenance operations.

The EACV and EAHV units boast full inverter technology on the core components of the refrigeration circuit.

• The four inverter-controlled compressors are automatically adjusted according to the system load;
• optimal control of fan speed through the use of inverters helps to maximize efficiencies and minimize noise.

Full inverter technology, combined with proprietary operating logics, ensure the highest efficiencies and consequent energy savings of the system.

The modular design is designed to reduce the time and cost of installing these units:

• Small footprint helps save space;
• With the integrated hydraulic manifold, the footprint due to hydraulics can be further reduced.

The wide range of options dedicated to user interface and remote connection make these units ideal for inclusion in a centralized system:

• The main operating variables can be conveniently controlled remotely with the controls available in the catalog;
• Through an AE-200E/A supervisor, VRF units and modular units can be controlled simultaneously resulting in a fully Mitsubishi Electric branded refrigeration system.

Even when placing several modules adjacent to each other, air circulation on the finned pack heat exchangers remains guaranteed on both short and long sides. This peculiar shape of the unit helps to improve efficiency while minimizing installation space.

The EACV and EAHV units both feature aluminum microchannel exchangers. In particular, the heat pump version boasts an exchanger with proprietary technology that can prevent coil icing even under the most critical environmental conditions.

The Mitsubishi Electric brand high-efficiency compressor is inverter-controlled and is optimized for the use of R32 refrigerant. The inverter automatically controls compressor frequencies based on various operating parameters, such as outdoor air temperature and load variations in the system, helping to achieve unparalleled seasonal efficiency. Through the use of the liquid injection system there is constant and precise control of the compressor discharge temperature. The induction crankcase heating mechanism is also taken advantage of, which significantly lowers the unit's standby consumption. Each unit is equipped with 4 compressors on independent refrigerant circuits. Together, these technologies ensure unparalleled efficiency and reliability.

The design of the fans has been specially studied to minimize their noise emissions (to 83dB(A)) while ensuring maximum efficiency. 

A version equipped as standard with an integrated hydraulic manifold (-N version) is available.

With optional accessories, available in the catalog, up to a maximum of six units can be easily connected. This eliminates the need to procure connecting piping between units on site, reducing installation work and the floor space of the system.

The operating parameters of each unit/group of units can be controlled by matching the remote controller PAR-W-31MAA or through a centralized controller AE-200E.

It is also possible to control the units through external signals provided by a third-party supervisory system. The type of control can be selected according to the customer's need. All basic functions can be performed by the remote controller.
