Energy Saving
Note:
The total heating / cooling load may vary depending on the climate or the other environmental conditions.
Heat Reclaim Ventilator (VAM series) recovers the thermal energy during cooling /
heating operation of air conditioner. Heat Reclaim Ventilator (VAM series) reduces the
cooling / heating load drastically and enhances the heating / cooling efficiency.
Proper use of Heat recovery ventilation and normal ventilation saves energy.
When the cooling operation is required in winter, use of heat recovery ventilation is not
efficient because the outdoor air temperature is normally lower than that of the indoor.
Thus, the proper use of ventilation mode enhances the heating / cooling efficiency.
Automatic Ventilation mode changeover
Refer to the CONTROL for the mode changeover.
The load is reduced at startup of the air conditioner by the following control.
Before the working hour, the room air is clean.
Therefore, the startup of Heat Reclaim Ventilator (VAM series) can be delayed.
