Briefly describe the difference between ventilation and air conditioning. 50

First, the methods are different.

1. Ventilation: Ventilation is to send the outdoor fresh air into the room after proper treatment (such as filtration, heating, etc.), and discharge the indoor dirty air or waste gas that does not meet the health standards to the outside after proper pesticide and disinfection treatment (in line with the emission standards) to maintain the freshness of the indoor air.

2. Air conditioning: Air conditioning should not only maintain the indoor air temperature and cleanliness, but also maintain a certain degree of dryness, humidity and flow direction and speed.

Second, the purpose is different.

1. Ventilation: Ventilation is realized.

2. Air conditioning: The purpose of the air conditioning system is to use artificial methods to make the indoor air temperature, relative humidity, cleanliness and airflow speed and other parameters meet certain requirements, so as to meet the higher and more accurate treatment of air quality in production and life.

Third, the classification is different.

1. Ventilation: classified according to ventilation power: natural ventilation, mechanical ventilation; According to the scope of ventilation services: full ventilation, local ventilation.

2. Air conditioning: there are two categories: comfort air conditioning and process air conditioning, the former is aimed at indoor personnel and creates a comfortable environment; The latter aims to maintain optimal indoor conditions for production processes, machinery and equipment, or storage items.

Compared with ventilation, air conditioning is a large range, which changes the temperature, quality and other indicators of the air. Ventilation refers to the flow of air, to be precise, the displacement of indoor and outdoor air.

Air conditioning includes two concepts: air conditioning and ventilation.

Ventilation is all about circulating air.

Air conditioning is the artificial way to adjust the quality or concentration of air in a certain place to a certain point.

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 function.

2. According to the working power, it is divided into make-up and mechanical ventilation.

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.

Teasing Answer]: b

This question assesses the early relationship between ventilation and air conditioning. Ventilation and air conditioning systems should be set up horizontally according to fire protection zones. The vertical orientation should not exceed 5 floors.

There are the following types: 1. Primary return air system; 2. a secondary return air system; 3. All-air air-conditioning system, this type of air used to bear indoor heat and humidity load can all come from the outside, or a local fresh air and a part of the return air can be adopted; 4. Reclaimed air and water type, the heat and humidity load of the room of this system is borne by the air and water that have been centrally disposed.

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.

<>1. The air conditioning ventilation mode is also called the air supply mode, which can circulate indoor air back and forth, that is, the role of indoor ventilation.

2. The ventilation mode is represented by a fan icon on the air old air adjustment, which can be blown into the room to hold the wind, cold air can be sent in summer, and hot air will be sent in winter, and the air volume has three modes: low, medium and high.

3. When the ventilation mode is turned on, the air conditioning fan starts to work, and the outdoor air can be blown into the room at this time, mainly for indoor ventilation.
