Benefits of Heat Exchange Fresh Air System 5

The self-balancing heat recovery unit is an energy-saving, environmentally friendly and healthy ventilation equipment, which is conducive to creating a comfortable and hygienic living space for the indoor environment where personnel stay and move. Through the self-balancing hot air ventilation unit, through the self-balancing adjusting device at the end of the pipe network, a part of the heat (in winter) or cooling (in summer) in the quantitative dirty air discharged from the room can be effectively discharged from the room to preheat or pre-cool the fresh air introduced from the outside, and the whole process is strictly configured with air supply and exhaust air volume, and at the same time, the energy in the discharge can be realized, so as to achieve a greater degree of energy-saving effect of the ventilation system. In the heat exchanger of the sensible heat mode, the condensate can be released from the air, the dirty gas can be discharged, and fresh air can be inhaled.

During the whole interaction process of introducing the exhaust air, part of the exhaust gas energy is transferred to the introduced fresh air to achieve heat energy exchange. In this way, the energy in the room is saved as much as possible. In addition, through the filter device, the polluted air is purified and disinfected to ensure that the fresh air sent into the room meets the national standard.

Generally speaking, the hot ventilation system installed in the building discharges the indoor dirty air, and at the same time filters the same amount of fresh air into the bedroom, which is less likely to cause room temperature fluctuations in all seasons, and can comprehensively solve the ventilation problem of the building. In an ordinary family, you won't smell the stench in the bedroom in the morning, and there will be no more dust; When sleeping in winter or turning on the air conditioner in summer, each room is also replenished with enough fresh air, and the room temperature is basically not affected by the outdoor temperature. If the design is reasonable and the VMC controllable ventilation system is adopted, indoor pollution and air conditioning diseases can be avoided.

Since then, the operating cost has been greatly reduced, and the indoor dirty and harmful odorous gases can be continuously discharged from the outdoors, and the outdoor fresh air can be purified and treated, and the oxygen-rich outdoor fresh air can be evenly transported to all indoor rooms. Regardless of the cold or heat, create a green and healthy environment with constant temperature, non-toxic, oxygen-rich and dust-free indoors. All rooms do not need to open windows, completely avoiding the interference of outdoor vehicle noise, dust, wind and rain.

The benefits of the fresh air system are many: supplementing the indoor fresh air to increase the oxygen content, diluting the concentration of harmful gases to ensure health, and exhausting the dirty air to the outdoors to breathe healthier.

Total heat exchange can make the outdoor air send to the room at a temperature close to the room, and its heat exchange principle can be described as follows, so I will not repeat it here. Since the fresh air outside is sent in at a temperature close to the room temperature, when the refrigeration and heating equipment such as air conditioning or floor heating equipment is activated, there will be no load on the air conditioning and other equipment due to the loss of heat energy, and secondly, the service life of the air conditioning equipment will be increased without the discomfort of sudden cold and heat.

It must be energy-saving Through heat exchange, the effect of pre-cooling and preheating of outdoor air can be achieved, which can save a lot of air conditioning, fresh air and heating loads.

It has the benefit of energy saving, reducing the loss of heat or cold air during indoor ventilation.

The full heat exchange fresh air system is a kind of fresh air system, which is divided into one-way flow fresh air, two-way flow fresh air and full heat exchanger fresh air system, which has many advantages of fresh air system and is the most comfortable and energy-saving fresh air system.

The principle of the full heat exchanger fresh air system.

The heat exchange fresh air system perfectly combines the overall balanced ventilation design with efficient heat exchange, the system is equipped with double centrifugal fans and integral balanced air valves, the system brings fresh air from the outside, distributes it to each bedroom and living room through the air supply duct system, and at the same time discharges the indoor turbid air collected from the corridor, living room and other common areas.

Complete indoor air replacement without opening windows to improve indoor air quality. The energy exchange between the fresh air flow and the turbid air discharged from the room at the heat exchange core in the fresh air system reduces the impact of fresh air introduction from the outside on indoor comfort and air conditioning load. In addition, the system can also be configured with an intelligent control system according to the needs of human comfort.

The fresh air system of general family decoration is ducted fresh air, and the fresh air system is summarized in three aspects: ventilation, air purification, and total heat exchange. Among them, the full heat exchange is the heat exchange between the inlet air and the exhaust air in the full heat exchanger of the fresh air system, and the heat in the exhaust air is partially reduced, which greatly reduces the additional energy consumption of the air conditioner due to the fresh air, such as 38 outdoor and 25 indoor in summer, after heat exchange, the air entering the room is about 29, which is mainly to save the electricity cost of air conditioning!

Generally, the fresh air system of home decoration is ducted fresh air, while Haoting fresh air is installed without ducted fresh air, in fact, the simple summary of the fresh air system is ventilation and air purification.

Heat exchange is the heat transfer caused by the relative displacement of each part of the fluid caused by the uneven density of the hot and cold parts in the fluid, and often the heat convection is accompanied by heat conduction.

As for the cold exchange you mentioned, I haven't seen it yet, and the fresh air system used in the home is nothing more than double circulation, heat exchange.

The differences are: different working principles, different functions, and different types of classification.

1. The working principle is different: the working principle of the fresh air system: according to the special equipment on the closed indoor side to send fresh air to the room, and then from the other side by the special equipment to the outdoor discharge, so as to meet the needs of indoor fresh air ventilation.

The working principle of the full heat exchanger: when the product is working, when the indoor exhaust air and fresh air flow through the heat exchanger core in a positive cross mode respectively, the temperature difference and the vapor partial pressure difference between the airflow on both sides of the airflow separator plate are caused, resulting in the total heat exchange process.

2. Different functions: the fresh air system is mainly used for indoor air purification and ventilation, and the indoor air polluted due to living and living process is updated with outdoor fresh air, so as to maintain the cleanliness of indoor air to a certain minimum standard. The energy efficiency of the full heat exchanger reduces the load of the air conditioning system, effectively solves the contradiction between improving indoor air quality and air conditioning energy saving, and plays an irreplaceable role in the field of air conditioning system energy saving.

3. Different types of classification: fresh air system can be divided into: unidirectional flow fresh air system, two-way flow fresh air system, ground air supply system, pipeline fresh air system, and single fresh air system; The total heat exchanger can be divided into: rotary full heat exchanger and plate-fin full heat exchanger.

Hello Dear Kiss Your question, here is the answer as follows: The heat exchange system is a heat exchange core with energy exchange function added to the host of the fresh air system. The polluted air discharged from the outside and the fresh air sent into the room are exchanged in this full heat exchange device, so as to achieve the purpose of cooling and heat.

To put it simply, the temperature in the indoor exhaust air in winter is exchanged for the air entering the outside through the heat exchange core to the hail tease, and the outdoor temperature is lower than the indoor temperature in winter, and the energy can be transferred through the heat exchange core when the two pass, so that the cold air sent into the room is close to the room temperature, so as to reduce energy consumption, save energy, and achieve the goal of health, comfort and environmental protection. Advantages of heat exchange fresh air system: the use of hot and cold technology, through heat exchange, the energy in the exhaust gas is transferred to the introduction of fresh air, in the hot weather in summer, the energy of indoor air conditioning can be retained, and the heating in winter can retain the indoor warm temperature, and the energy consumption of fresh air treatment can reach 70% under normal circumstances.

Function of heat exchange fresh air system: 1. There is a full heat exchange fresh air system, which can exchange the turbid air indoors and the fresh air outside, and can adjust the indoor humidity as much as possible, so that the indoor will not be too humid or dry, which can affect the comfort of the indoor environment.

The total heat exchanger is a high-efficiency and energy-saving heat exchanger device, which preheats or precools the fresh air introduced into the fresh air system through the waste heat in the exhaust, and the heat exchange membrane plays the most central role in the total heat exchanger.

People are paying more and more attention to respiratory health, so the fresh air system has become the choice for many families to improve indoor air quality. The fresh air system can remove the hazards of harmful volatiles such as formaldehyde and benzene from interior decoration materials through ventilation. In 2019, Panasonic Fresh Air launched a new full heat exchanger with better performance and more intelligent operation - the new DC motor full heat exchanger.

Equipped with multiple probes, it can monitor the indoor air quality in real time, prompt the user to turn on the machine, and automatically adjust the operation mode. The internal circulation mode can effectively block outdoor pollution; The heat exchange mode is suitable for air-conditioned rooms that are closed for a long time, increasing the oxygen content in the room and delivering fresh air to the room; In the transitional season of spring and autumn, the normal ventilation mode can be turned on; When the weather is cold outside, the mixed air mode can be turned on to deliver fresh air at the right temperature to the room while protecting the machine from condensation.

When used with air conditioners, it can also assist air conditioners to be more energy-saving. For example, in summer, the outdoor 38, the indoor 25, through the heat exchange core, the air entering the room is about 29, the main thing is to save the air conditioning electricity bill! In addition, Panasonic's new DC motor full heat exchanger is equipped with a reinforced filter and an activated carbon filter for dual purification, and the purification efficiency of the whole machine reaches 98%, so that the whole family can enjoy clean and fresh air quality.

Working principle of fresh air total heat exchanger Working principle:

When the product is working, when the indoor exhaust air and fresh air flow through the heat exchanger core in a positive cross mode, due to the temperature difference and vapor partial pressure difference between the air flow on both sides of the air flow separator, the heat and mass transfer phenomenon is presented when the two air flows through the separator, causing the whole heat exchange process.

When running in summer, the fresh air obtains cooling capacity from the exhaust air of the air conditioner, which lowers the temperature, and at the same time is dried by the air conditioner, so that the moisture content of the fresh air is reduced; When operating in winter, the fresh air gets heat from the exhaust air of the air-conditioned room, and the temperature rises.

In this way, through the full heat exchange process of the heat exchange core, the fresh air is allowed to generate energy from the exhaust air of the air conditioner.
