Integrated Energy Recovery Make-Up Air Units
The PowerFX system is designed to recover the available energy from a hot air vent duct of a building. It uses this energy to preheat the fresh air of an Airex AMX Series air make-up, or any other air make-up unit.
The lack of fresh air can be a problem in an industrial building. Air make-up units, such as the AMX, are installed in these buildings to solve this problem. However, in situations that require a large volume of fresh air, these units can become energy-consuming, especially if they are used to heat the building. With the PowerFX, the exhaust air energy released to the atmosphere can be recovered. This energy is then returned to the air make-up unit.
How it Work
Firstly, an energy recovery coil should be installed in the air evacuation duct of the building, ideally of similar capacity (same air flow). The coil absorbs energy that would otherwise be released to the atmosphere. A refrigerant loop carries the captured energy to a compressor which is installed in the air make-up unit. The compressor operates under the principle of heat pumps. It releases a high temperature fluid from a low temperature source. This high temperature fluid is used to preheat the fresh air before it is fed into the building.
