Many people do not know much about heat exchanger products. In fact, the heat exchanger means that during the summer operation, the fresh air system obtains cooling capacity from the central air conditioning exhaust system, the temperature is reduced, and the central air conditioning is dry, thereby reducing the moisture content of the air conditioner. Fresh air system. During winter operation, the fresh air system will absorb heat from the exhaust system of the central air conditioning room and the temperature will increase. In this way, according to the entire heat exchange process of the heat exchange core, the fresh air system is allowed to obtain kinetic energy from the central air-conditioning exhaust system, which has the practical effect of environmental protection and energy saving, and maintaining a comfortable indoor temperature.

1. First of all, there must be a high point about the efficiency of the heat exchanger, that is, the volume of the heat exchanger core. If the practical effect often mentioned above is to be maintained, the heat exchanger core in the new wall-mounted fan also needs to occupy about 1/3 of the volume, and the efficiency of the entire heat exchanger must be about 50%-70%, so reasonable efficiency can be achieved.

2. After expanding the volume of the heat exchanger core, it will inevitably cause harm to the exhaust volume. Under all normal conditions, after using the heat exchanger core, the same fresh air system will reduce the exhaust volume efficiency by half. After the effect of the heat exchanger is applied to the new fan, the amount of exhaust will become smaller, and a small amount of exhaust will cause damage to the actual cleaning effect in the room.

3. The direct extension type is actually used in the wall-mounted new fan. There is actually a key point. At this stage, ordinary heat exchanger filter elements are made of aluminum, plastic, paper and epoxy resin. It is a paper filter element. In winter applications in northern regions, the outdoor temperature should usually be very low. It is very easy to freeze the filter element, resulting in a lack of actual heat exchange effect.
