The Proposed Technologies
Innergytech Company proposes 3 different types of air-to-air energy
recovery technologies to OEM. Here is an overview of the available
technologies. (For more detailed information about the complete line
of products available, please visit our "PRODUCT INFORMATION"
Section).
Composed of many layers of aluminum or polypropylene sheets, this
passive exchanger will transfer heat from one air stream to the other;
this is commonly called a heat exchanger, transferring sensible energy
only.
When the plate exchanger is composed of layers of polymeric membrane
sheets, the plates allow not only heat but also moisture to be transferred
from one air stream to the other. This type of device is commonly
called an energy exchanger, transferring both sensible and latent
energy (moisture).
This heat exchanger is a device composed by a series of independent
tubes divided by a middle partition, thus insuring the separation
of supply and exhaust air flows. The tubes contain refrigerant that
vaporizes on the warmer air flow channel and condenses on the colder
air channel, thus accomplishing the heat transfer.
This device proposes a rotating surface composed by small aluminum
cells, which transfer sensible energy (hot or cold air).
When desiccant is added to the aluminum cells, the heat wheel transfers
both sensible and latent energy (moisture) from one air stream to
the other.
The Benefits of Energy Recovery for OEM’s

Reducing the load of heating and cooling equipment |
|
|
|
|
|
|
|
While incorporating an energy recovery device in their system, OEM’s
will reduce the load of their air conditioning equipment. Design load
savings of up to 4 tons per 1000 cfm* cooling and 80,000 Btu/hour**
per 1000 cfm* heating are easily achievable with the proper energy
recovery device.

|
Meeting the codes and Standards at lower costs |
|
|
|
|
|
|
|
To meet ASHRAE Standard 62, OEM’s must build air-handling units
capable of introducing 15 to 60 cfm* of fresh air per person into
the building. Heating, cooling or dehumidifying this fresh air can
be somewhat expensive. By applying an energy recovery device in their
system design, OEM’s can reduce the cost of conditioning this
volume of mandatory supply air.

Increasing the system efficiency |
|
|
|
|
|
|
|
While recovering the otherwise waste energy from the exhaust air and
transferring it back to the supply air, the efficiency of the cooling
and heating devices in the air handling units is greatly improved.
*cfm : cubic feet per minute. This is the common
airflow measure unit.
**Btu/hour : British thermal units per hour. Measure unit to evaluate
energy cost.
