Heat exchangers are generally combined with fresh air systems. Of course, some total heat exchangers are also called electric heat exchange fresh air systems. Various names are the combination of fresh air systems and electric heat exchange, which can be said to be a small upgrade of fresh air systems. For the fresh air system with electric heat exchange, the indoor temperature can be guaranteed not to decrease due to the outdoor temperature in winter. Because the outdoor air is constantly flowing in, if it does not go through electric heat exchange, the more air that enters the room, the lower the temperature.

When the total heat exchanger is running, when the indoor exhaust and fresh air pass through the core of the heat exchanger in a cross manner respectively, the air flow on both sides of the air flow barrier has a temperature difference and a vapor partial pressure difference, and heat transfer occurs when the two air flows pass through the barrier. Phenomenon, resulting in the entire heat exchange process. During summer operation, fresh air obtains cold energy from the air-conditioning exhaust, reduces the temperature, and at the same time dries in the air-conditioning wind to reduce the humidity of the fresh air. During winter operation, fresh air obtains heat from the air-conditioning room exhaust and the temperature rises. In this way, through the entire thermal replacement process of the thermoelectric core, new air can recover energy from the air conditioning exhaust.

1. total heat exchanger also has its own characteristics:

(1) The box body is made of galvanized or aluminum-zinc plate, with a sound-absorbing layer inside, two super effective filters, and the purification efficiency is still high.

(2)220V ultra-low sound blower, stable operation and low noise.

(3) Imported nano paper electrothermal exchange core and aluminum filter are available.

(4) Standard 3-level speed control switch and LCD panel options. (V) suitable for offices, hotels, learning and other places.

Advantages of 2. total heat exchangers

1. High heat exchange efficiency:

Through the advanced counter-flow structure design, the air heat exchange time of the module becomes longer, and the rod-shaped ventilation holes greatly increase the heat exchange area, so the heat exchange efficiency is increased by 5% to 10% compared with the cross-flow core.

2. Energy recovery

The electric heating type is a nano microporous thermal film made of polymer materials, which has good thermal conductivity and moisture permeability, good air tightness, and the electric heat recovery does not pollute the fresh air. The sensible heat type is made of aluminum foil, which has high corrosion resistance, high temperature resistance and temperature exchange efficiency.

The total heat exchanger is a very good energy-saving equipment and has broad application prospects. The overall heat exchanger effectively reduces the load of the air conditioning system, saves the energy consumption and operating cost of the air conditioning system, and effectively solves the problem between indoor air quality and air conditioning energy saving. Contradictions have an irreplaceable role in the field of air conditioning system energy saving.
