中央空调系统由冷热源系统和空气调节系统组成。采用液体汽化制冷的原理为空气调节系统提供所需冷量，用以抵消室内环境的冷负荷；制热系统为空气调节系统提供用以抵消室内环境热负荷的热量。伴随社会的不断前进与发展，空调被应用于各种建筑物中，包括影院，商场，教师，办公室等。这种对空调大量的需求量使我国的能源消耗越来越大，针对这种过度的能源消耗应采取相应的解决措施。安装空调新风系统不仅可以改善空调的工作效率，也可以节省能源的消耗，是一举两得的处理方式。 

The central air conditioning system is composed of a cold and heat source system and an air conditioning system. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for air conditioning system to counteract the cooling load of indoor environment, and the heating system provides heat for the air conditioning system to counteract the heat load of indoor environment. With the continuous progress and development of the society, air conditioning is applied to various buildings, including theaters, shopping malls, teachers, and offices. The large amount of demand for air conditioning makes the energy consumption of our country more and more large, so the corresponding measures should be taken to solve this excessive energy consumption. The installation of a new air conditioning system can not only improve the efficiency of the air conditioning, but also save energy consumption. It is a way of handling two birds with one stone.

伴随人们生活水平的不断升高，物质享受能力也不短提升。在大型的建筑物中，相关部门为了更好的给予顾客物质服务，在建筑物中大量安装空调，满足顾客对室内温度的要求。据相关资料显示，空调夏季工况冷负荷设计中新风负荷占较大比重。众所周知，新风负荷的计算与人员密度及人数有一定关系，但人数的变化是无法预测的，而且人数的变化也受季节与天气等因素的影响。此外，建筑物的规模、位置及其经营的范围也会对人员的流动产生一定的影响。 

With the rising of people's living standards, the ability to enjoy material is not very short. In large buildings, the relevant departments in order to better provide customers with material services, air conditioners are installed in buildings to meet the indoor temperature requirements of customers. According to the relevant data, the new wind load in the cold load design of the air conditioning in the summer working condition accounts for a large proportion. As we all know, the calculation of fresh air load is related to the number of people and the number of people, but the change of the number of people is unpredictable, and the change of the number is also affected by factors such as season and weather. In addition, the scale, location and scope of the building will also have a certain impact on the flow of personnel.  

 

 

二 中央空调安装新风系统节能措施 

Two central air-conditioning installation and energy saving measures of air system

 

 

中央空调安装新风系统节能的方法就是利用其中的热交换回收空调排风中的能量，为使新风系统更加节能，采用新风、排风全热交换的方法，最大程度上达到预期效果。在进行热回收装置时应根据当地实际自然条件及经济发展水平等多种现实因素进行全面考虑，结合技术与经济的比较与分析，最终选择科学合理的热回收装置，进而实现中央空调新风系统节能的目的。 

The way of central air conditioning to install fresh air system is to use the heat exchange to recover the energy from the air conditioning exhaust. In order to make the new air system more energy efficient, we adopt the new heat exchange method of fresh air and exhaust air to achieve the desired effect to the greatest extent. In the heat recovery device should be fully considered according to the actual local natural conditions and economic development level and other practical factors, combined with the comparison and analysis of technology and economy, the final choice of scientific and reasonable heat recovery device, thus achieving the purpose of energy-saving central air conditioning system.  

 

 

1）新风、排风全热交换实施。热回收方式分为全热回收和显热回收装置两种。其中全热回收装置的工作原理是空气与空气的能量回收通风装置，并且通过对室内外空气焙差的利用，运用全热回收机芯的导热透湿功能，双向置换通风产生能量的交换，从而让新风最大程度的获取排风焙值，节约新风在预处理过程中的能量消耗，最终实现既节能又换气的目的。在整个过程中节约的能量有显热和潜热，节能效果十分可观，而且全热交换的效率也得到了提升。排风中热量回收的装置种类众多，转轮式与板翘式不仅可以实现全热交换，而且可以进行显热交换；热管式与热回收回路只能进行显热交换。适合我们日常生活的热回收装置就是转轮式和板翘式交换器。转轮式换热通过排风与新风逆向交替通过转轮，转轮自身对其中的清洗扇进行控制，从而适应各种不同的空气，提高使用效率。由于转轮式换热是两种空气的相互交替，所以在一定程度上会出现交叉污染，所以，流过的气体应保证是无害的。根据先进科学技术的改造，空调的气密安全性较高，所以在全热回收的过程中不会污染新风。

1) the new wind, the exhaust air all heat exchange implementation. The heat recovery methods are divided into two types: full heat recovery and sensible heat recovery. The working principle of total heat recovery device is energy recovery ventilation device of air and air, and through the use of indoor and outdoor air curing the use of heat recovery heat moisture movement function, bidirectional displacement ventilation energy exchange, so that fresh air to maximize exhaust baking value, saving fresh air in pretreatment in the process of energy consumption, energy saving and ultimately achieve the purpose of ventilation. The energy saved in the whole process is sensible and latent heat, and the efficiency of energy saving is very considerable, and the efficiency of all heat exchange has also been improved. There are many kinds of heat recovery devices in the exhaust system. Rotary and plate warping can not only achieve full heat exchange, but also conduct sensible heat exchange. Heat pipe and heat recovery circuit can only conduct sensible heat exchange. The heat recovery device for our daily life is the wheel type and the plate warping switch. The rotary heat exchanger passes through the runner in reverse direction through the exhaust air and the fresh air, and the impeller itself controls the cleaning fan itself, so as to adapt to various air and improve the service efficiency. Because rotary heat exchange is the alternation of two kinds of air, there will be cross contamination to some extent, so the gas flowing through it should be harmless. According to the reform of advanced science and technology, air conditioning has high air tightness, so it will not pollute the new wind in the process of full heat recovery.
