– Free-cooling system for ducted indoor unit
Econofresh is the optional kit attached to the ducted indoor units to introduce fresh air into the room. It can work in a free-cooling mode for even more energy efficiency.
– HVAC systems with fresh air introduction
Econofresh is a module attached to the air-inlet side of Ducted indoor units. Via a set of shutters, it makes it possible to mix FRESH and RECYCLED air to create “free-cooling”, improving indoor air quality.
How does it work?
When the outside ambient air temperature is lower than the indoor room air temperature, “free-cooling” can be activated to stop the outdoor unit compressor and reduce energy waste.
Versatile performance can be ensured too because two different operating modes can be selected.
- Standard mode: ideal operation for mild temperatures
- All Fresh mode: ideal for spaces characterized by a high internal thermal load throughout the year

– Easy installation of Econofresh free-cooling module
Installation is easy. First, attach Econofresh directly to the air inlet of the ducted indoor unit. Then, attach both the return-air duct & fresh-air duct side by side to Econofresh. Lastly, you can maximize operations to meet your air conditioning and climatisation needs.
- Operation via enthalpy control: to optimize free cooling regulation and control, the system can be fitted with an enthalpy sensor kit. Fitting the system with an enthalpy sensor kit to manage fresh and re-circulated air in relation to air enthalpy reading and temperature reading, assuring accurate control and guarantee the comfort of people present in the building.
- Operation via CO2 sensor: to guarantee enhanced indoor air quality, the Econofresh system can be also coordinated by installing an optional C02 sensor.
