Lower Global Warming Potential Air Conditioning

OPA Econex R32 refrigerant units offer a significant reduction in Global Warming Potential (GWP) per kW of cooling or heating, achieving a 71% - 81% reduction compared to R410A systems (GWP 2088). With a smaller refrigerant charge and a GWP of 675, these units contribute to environmental sustainability.

As higher GWP refrigerants face increasing costs due to emissions tax levies, specifying R32 systems like Econex Pro represents a significant reduction in future costs associated with owning and maintaining these systems.

Superior Comfort Control

Econex Pro units provide superior comfort control by considering indoor and outdoor humidity levels, making autonomous decisions to satisfy setpoint conditions. They offer multiple autonomous comfort modes:

• Cooling - High Latent
• Cooling - High Sensible
• Cooling - Standard
• Cooling - Reheat* (*available with optional reheat coil)
• Heating - Dehumidification
• Heating - Standard
• Comfort Zone - Fan only

Unlike traditional systems that rely solely on temperature setpoints, Econex Pro's 7 modes of comfort are designed around dewpoint levels on a psychrometric chart. This allows for precise comfort needs by managing moisture and temperature within specific limits.

The adaptive software logic ensures the system automatically switches between modes as required. For instance, during hotter, wetter months, 'Cooling - Reheat' mode might operate. As ambient conditions change and sensible heat load increases, the system may transition to 'Cooling - High Latent' or 'Cooling - Standard' modes, continuously optimizing for comfort and minimizing energy consumption.

Quick and Easy Set-Up: Pre-set optimization and pre-programmed advanced control logic ensure effective and efficient operation out-of-the-box.

Seasonal Energy Efficiency

The OPA Econex Pro, equipped with multiple independent refrigeration circuits, inverter compressors, and EC plug fans, is engineered to maximize part-load efficiency. Its Absolute Autonomous Control provides accurate temperature and humidity control under all conditions by precisely managing evaporating and supply air temperatures.

Inverter Compressors: Offer ultra-high efficiency with a 16:1 turn-down ratio, soft starting to reduce power consumption at startup, and reduced start/stop cycles for longer life. This technology matches capacity to load, avoiding temperature fluctuations and minimizing energy input.

Extreme Weather Operation: Designed for harsh conditions, these units operate reliably in ambient temperatures ranging from -10°C to +50°C.

Seasonal Energy Efficiency (SEER): Econex Pro Inverter technology delivers superior seasonal performance. Compared to older models (e.g., ECO OPA 960), the OPA 970 Econex Pro demonstrates considerably higher seasonal energy efficiency factors (TCSPF and SEER) and offers significant energy savings (kWh) in annual cooling consumption.

Energy Saving Technology

Intelligent system control technology provides leading energy efficiency with precision control of the air conditioner's refrigeration system. The high-efficiency EC fan motors are up to 50% more energy efficient than belt-drive or AC motor alternatives, enabling quiet operation with slow ramp-up and no sudden noise changes.

EC Fan Technology Benefits:

• Programmable for exact airflow
• High static pressure
• Enables variable airflow operation
• Longer motor life due to lower running temperatures
• Lower maintenance and commissioning costs
• Slow ramp-up for quiet operation
• Longer bearing life due to soft start

EC fans contribute to overall application efficiency by keeping refrigerant pressure constant, reducing compressor loads and optimizing efficiency within the compressor's operating envelope.

EC Plug Fans: The unit's integrated electronics continuously monitor static pressure and adjust fan speed accordingly for accurate and efficient control. Fan speed can also be controlled via external signals (input or Modbus).

EC Plug Fan Benefits:

• Up to 50% more efficient than AC fan technology
• High static pressure
• Minimized power consumption under optimized floating head pressure control
• Quiet operation mode

Electronic Expansion Valves (EEV)

EEVs optimize refrigeration systems by ensuring the evaporator coil is fully utilized at all times, leading to increased energy savings. They also allow for lower discharge pressures based on ambient conditions by increasing EC condenser fan speed, resulting in even higher savings.

EEV Benefits:

• Enable improved efficiency and reduced operating costs at part-load conditions.
• Facilitate maximized energy savings during shoulder seasons when air conditioning systems often run at part-load.
