Central fresh air system type

Author:Source:Visits:Date:2013/11/14

Central fresh air is to achieve a ventilation of the whole house of a device, at present, in the domestic market, the central fresh air system type mainly one-way fresh air central system, two-way flow of the central fresh air system and the whole heat exchange center fresh air system. Before we understand these three types of central fresh air system, first look at what is the central fresh air system.

First, what is the fresh air system

Central fresh air system, is the outdoor fresh air filtered to the interior, while the dirty air out of the room to achieve the balance of the air at the same time, so that a closed space to achieve a scientific air convection, also equal to the closed The room added a breathing system. It is to ensure that the enclosed room 24 hours have fresh air, living in the room like a green forest, but also to ensure that the room clean and quiet, isolated from the outside of the dust and noise, but also effectively avoid the condensate Exposed mold caused by moldy phenomenon.

Second, the central fresh air system type Description:

Central fresh air system in accordance with the air organization can be divided into: one-way flow of the central fresh air system, two-way flow of the central fresh air system, the whole heat exchange center fresh air system.

Central fresh air system type 1: one-way fresh air ventilation system

Unidirectional flow of the central fresh air system that is "forced exhaust, natural into the wind" system. Its working principle is to rely on the work of the host suction, the formation of indoor negative pressure, the dirty air through the air duct to the outdoor, in order to balance the indoor negative pressure, the room outside the relatively fresh air from the pre-installed air into the room , In order to achieve the purpose of ventilation.

Central fresh air system type 2: two-way flow of fresh air ventilation system

Two-way flow of the central fresh air system that is "forced exhaust, forced air" system, by a group of forced air supply system and a group of forced exhaust system. And the one-way flow difference is that the form of air from the natural into the wind to force the air supply, into the air into the wind more active, the new air from the air supply system into the indoor pipeline, dirty air through the exhaust system piping concentrated to the outside, for Gas effect is more obvious.

Central fresh air system type 3: all hot exchange fresh air ventilation system

The central air system of the whole heat exchange overcomes the shortcomings of the above system. The whole heat recovery system is added to the main body. The air entering and exiting through the heat exchangers arranged in the main body is preheated and pre-cooled energy exchange. 70% of the energy of the air, even if the temperature difference will not affect the indoor temperature. The air is blown in different parts of the same room, fresh air is sent to the room through the pipe, and the dirty air is pumped out of the air outlet of each room, so that in each relatively independent space New convection, effectively guarantee the quality of the air.
