Heat recovery ventilation system It is an upgraded version of the two-way flow fresh air system, that is, the heat recovery device is added to the function of “forced exhaust air, forced air supply”, and it is an efficient, environmentally friendly and energy-saving all-round ventilation system
Introduction to heat recovery ventilation systems
The Heat recovery ventilation system uses the full heat exchange core in the machine to carry out heat exchange with the outdoor air before the outdoor air is introduced into the room, and the hot air outside is pre-cooled/preheated and then sent into the room to prevent the loss of indoor air energy.
Let’s take a look at an example, as shown below:
During indoor cooling in summer, the 26℃ indoor air passes through the heat exchange core, and the cold capacity is recovered by the heat exchange core and then goes out of the room. After the 33℃ outdoor air passes through the heat exchange core for cold capacity exchange, the temperature is about 27℃ when it is sent into the room.
During indoor heating in winter, the indoor air of 20 ° C passes through the heat exchange core, and the heat is recovered by the heat exchange core and then goes outside. After the outdoor air of 0C passes through the heat exchange core for heat exchange, the temperature is about 18° C when it is sent into the room. To achieve ventilation while maintaining indoor temperature, energy saving and environmental protection.
The whole house heat recovery ventilation system is comfortable and energy-saving. While ventilating the room, it can also recover energy from the air discharged from the room, making the indoor temperature suitable. It is a better choice when the budget is sufficient and the temperature difference between indoor and outdoor is large.
