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.

2）新风、排风全热交换设计。（1）科学合理的设置空调机房。在进行中央空调设计时，为保证各方利益，空调机房的面积往往较小。所以，其空间的利用率自然较低。室外进风口与排风口在设计时要求间隔越远越好，从而可以更好的避免气流的短路。空调中全热转换器的接管较多导致其系统管路较为复杂。此外，由于我们周围空气质量的原因，积灰现象时常发生，这种现象的产生导致过滤器的堵塞，所以在使用过程中应注重过滤器的清洗工作。中央空调的全热回收必须保证新风与排风系统在相同处布置，所以在进行设计时应将系统的划分及风道的设置，热回收装置及送排风机的设置进行全面统筹，使整个系统划分合理。（2）排风热回收装置的合理设置。空调供冷与供暖的最小风量对全热交换器的大小具有直接影响。所以，在使用新风进行空调供冷时不能开启全热交换器。全热交换器一旦开启，新风就会被排风加湿，在换热过后新风供冷的效果就会降低。若一定要使用新风供冷，则必须要在新风与排风道上设置旁通风道，这样空气就不会经过交换器。

2) the design of the heat exchange of the fresh air and the exhaust air. (1) setting up the air-conditioned room scientifically and reasonably. In the design of central air conditioning, in order to ensure the interests of all parties, the area of the air-conditioned room is often small. Therefore, the utilization of space is naturally low. The outdoors air inlet and exhaust port are designed to require the farther the better, so that the short circuit of the air flow can be avoided. The system pipeline is more complex because of the more full heat converter in the air conditioner. Besides, due to the air quality around us, the phenomenon of dust accumulation often occurs. This phenomenon causes the blockage of filters, so we should pay attention to the cleaning of filters in the process of using. The total heat recovery of central air conditioning must ensure that the new air and exhaust system are arranged at the same place. Therefore, when designing, we should comprehensively divide the system partition and the air duct setting, the heat recovery device and the sending and draining fan settings, so that the whole system can be divided into a reasonable one. (2) reasonable setting of exhaust heat recovery device. The minimum air volume of air conditioning cooling and heating has a direct impact on the size of the total heat exchanger. Therefore, the full heat exchanger can not be opened when the new wind is used for air conditioning for cooling. Once the heat exchanger is opened, the fresh air will be humidified by the exhaust air, and the effect of the new air supply will be reduced after the heat exchange. If the new wind is to be used for cooling, the bypass duct must be set up on the new wind and exhaust duct so that the air will not pass through the exchanger.
