Heat Recovery Ventilator (HRV)

The heat recovery ventilator is a energy-saving ventilation solution, introducing fresh air into rooms to help you breathe easy at anytime.

Energy Saving Analysis

In summer operation, when the cold energy of 27℃ air discharged from indoor pass through the heat exchanger, the 35℃ outdoor hot air is pre-cooled to 29.4℃ fresh air and supplied to indoors, as shown above, the air conditioner only needs to cool the air by 2.4℃ to maintain a comfortable room temperature and fresh air. In this process, the discharge air pre-cools the fresh air by HRV, The temperature recovery efficiency in cooling is 70% max, and enthalpy exchange efficiency is 57% max.

Winter Energy Saving Analysis

In winter operation, when the heat energy of 21℃ air discharged from indoor pass through the heat exchanger, the 5℃ outdoor cold air is pre-heated to 17℃ fresh air and supplied to indoors, as shown above, when outdoor 5℃ air and indoor 21℃ air pass through the HRV, the fresh air supplied to indoors is about 17℃, the air conditioner only needs to heat the air by 4℃ to maintain a comfortable room temperature and fresh air. The temperature recovery efficiency in heating is 75% max, and enthalpy exchange efficiency is 63% max.
