What is the difference and connection between ventilation system and air conditioning system?

If you want to achieve the purpose of indoor ventilation, you still have to buy a fresh air system. Speaking of the connection between the two, taking the best-selling green island wind heat fresh air system in the current market as an example, when it is used in combination with the air conditioning system, the indoor air and outdoor air with different temperatures exchange heat when flowing through the core, which can make the fresh air sent to the room in summer cool down, and the fresh air sent to the room in winter to heat up, so as to reduce the energy consumed by the air conditioning system to treat the fresh air to the indoor air state, reduce the air conditioning load and daily operating costs, and achieve the dual purpose of ventilation and energy saving.

The air conditioner is a fresh air conditioning system, there is no need for a fresh air system, the air conditioner itself has hot air and cold air, and it is fully equipped with various functions of air conditioning, so there is no need to add a fresh air system.

1.Differences between ventilation and air-conditioning systems (1) Types of ventilation systems Ventilation systems are divided into partial ventilation and one-sided ventilation according to their scope of function; According to the working power, it is divided into artificial ventilation and mechanical ventilation; Distribute (or inlet) air and exhaust air according to the direction of medium transmission; According to the efficacy and nature, it can be divided into ordinary (ventilation) ventilation, industrial ventilation, incident ventilation, fire ventilation and anti-ventilation. (2) Category of air-conditioning system 1

According to the use of the air conditioning system, it can be divided into comfortable air conditioning system and process air conditioning system; 2.Press the cumbersome hot and warm back load.

The difference between the ventilation system and the air conditioning system is whether there is a role in regulating the temperature or not, and the connection is that it is used in the wind system.

I record the difference between my space with him, his sexuality, and his connection I think is very close, and we will all be better used and helped.

The difference between a ventilation system and an air-conditioning system is that a multi-party system is maintained to multi-part, and an air-conditioning system is maintained to the full.

Difference Between Ventilation and Air Conditioning System:

1. Types of ventilation systems.

1. The ventilation system is divided into partial ventilation and one-sided ventilation according to its scope of action, and 2. It is divided into pretentious ventilation and mechanical ventilation according to the working power.

3. The medium transmission direction is distributed (or inlet) and discharged.

4. The efficacy can be divided into ordinary (ventilation) ventilation, industrial ventilation, incident ventilation, fire ventilation and self-defense ventilation.

Second, the type of air conditioning system.

1. The use of the air conditioning system can be divided into comfortable air conditioning system

2. The classification of warm back load medium can be divided into full air system, water system, air water system and refrigerant system according to the system.

3. The source of air can be divided into direct source system, open system and return air system.

The concentration level of air disposal equipment can be divided into centralized air-conditioning system, semi-centralized air-conditioning system and evacuation air-conditioning system. There are also natural ventilation drop temperature, solar heating, the use of heat pipes, heat pumps, steamer cooling, full heat exchanger to add waste heat or the application of atmospheric heat, the use of variable air volume, variable water technology to save energy consumption and other systems.

Ventilation is changing the air in the room to keep the air fresh, while air conditioning is adjusting the temperature in the room, and that's the difference.

The common saying of ventilation should be used more by HVAC professionals, mainly used to study the airflow in the environmental area, including air volume, wind speed and so on. The more detailed name of air conditioning is air conditioning, which refers to the temperature regulation of the environmental area, and the air conditioner includes two parts: refrigeration and heating, heating in winter and cooling in summer. The biggest difference between ventilation and air conditioning is that the former reflects air volume and wind speed, while the latter reflects temperature.

Ventilation only keeps the indoor air in a circulating state, which can be used to exchange the indoor dirty air with the outdoor clean air to ensure that the indoor air is maintained in a healthy and fresh state.

Air conditioning is to cool and dehumidify the indoor air, and even add functions such as air purification and filtration and ventilation while adjusting the temperature and humidity, which belong to the category of air conditioning (air conditioning).

The former is the temperature is uncertain, the latter requires the temperature!

First, the reference is different.

1. Ventilation: air circulation; Breathable.

2. Air conditioner: a device for regulating air.

Second, the focus is different.

1. Ventilation: It focuses on the flow of air.

2. Air conditioning: This means the comprehensive regulation of temperature and humidity.

3. Different citations and usages.

1, ventilation: Chen Dengke "Red Dragon and Danfeng" Part 1 Part 9: "It's not him who comes to ventilate, I'm still in the dark." ”

2. Air conditioning: Yan Guopei, Chapter 7 of "Bashan Yue": "His father's house is too old-fashioned, and the light in the room is dim and the ventilation is not smooth. ”

Ventilation can be understood as just ventilation, ventilation; For example, installing an exhaust fan in a room is to ventilate the room, and opening doors and windows is to ventilate.

Air conditioning, air conditioning, involving temperature regulation and air humidity regulation, is not an exhaust fan or open doors and windows can be realized.

Ventilation: The displacement of air in an area.

Air conditioning: Adjust and control the temperature and humidity of certain environments. Ventilation is also a means of air conditioning.

Ventilation is the exchange of air between the inside and outside, while the air conditioner only regulates the temperature inside and outside.

Ventilation is mainly used to study the airflow of the environmental area, including air volume, wind speed, etc., and air conditioning refers to the temperature regulation of the environmental area, including cooling and heating.

The biggest difference is that the former reflects the wind speed and volume, while the latter reflects the temperature.

Ventilation system: 1. The ventilation system is divided into partial ventilation and one-sided ventilation according to its scope of action;

2. According to the working power, it is divided into artificial ventilation and mechanical ventilation;

3. Divide air supply and exhaust air according to the direction of medium transmission;

4. According to the efficacy and nature, it can be divided into ordinary ventilation, industrial ventilation, incident ventilation, nuclear hail, fire ventilation, etc.

Air conditioning system: 1. According to the use of air conditioning system, it can be divided into comfortable air conditioning system and process air conditioning system;

2. According to the classification of cumbersome heat and warm back load medium, it can be divided into full air system, water system, air water system and refrigerant system;

3. According to the system use of air jujube or origin, it can be divided into direct source system, open system and return air system;

4. According to the concentration level of air disposal equipment, it can be divided into centralized air-conditioning system, semi-centralized air-conditioning system and evacuation air-conditioning system.

The ventilation and air conditioning project consists of a ventilation system and an air conditioning system.

1. The ventilation system is composed of a supply and exhaust fan, an air duct, an air duct component, a muffler, etc. The air conditioning system is composed of air conditioning cold and heat sources, air handlers, air transmission pipelines for transportation and distribution, as well as automatic control and regulation of indoor temperature, humidity, air flow speed and cleanliness by air conditioners.

2. The oxygen content in the air, the concentration of carbon dioxide and carbon monoxide, the content of dust and floating microorganisms, the number of ions and organic volatiles in the air are all included in the indoor air index.

3. Through the analysis of the influencing factors of air conditioning and ventilation system on indoor air quality, effective measures to improve indoor air quality are put forward from many aspects.
