空调机的制冷量是指空气通过蒸发器、表面冷却器、喷水室后被降温所需的冷量。 空调冷负荷是指空调房间为维持一定温、湿度参数，排除室内余热、余湿所需的冷量。 在稳定的工况下，空调机的制冷量等于空调冷负荷，送风管道冷量损失和排风的冷量损失之和。 什么是露点温度？什么叫机器露点温度？
在空气所含水气量（含湿量）不变的情况下，通过冷却降温而达到饱和状态时的温度称为露点温度。空气在露点温度下，相对湿度达100%，此时干球温度、湿球温度、饱和温度及露点温度为同一温度值。 在空气调节技术中，当空气通过冷却器或喷淋室时，有一部分直接与管壁或冷冻水接触而达到饱和，结出露水，但还有相当达的部分空气未直接接触冷源，虽然也经过热交换而降温，但他们的相对温度却处在90~95%左右，这时的状态温度称为机器露点温度。 什么叫空调、空调基数和空调精度？ 空调是空气调节的简称，是使室内空气温度、湿、清洁度和气流速度（简称四度）保持在一定范围内的一项环境工程技术，他满足生活舒适和生产工艺两大类的要求。
空调基数－-指空调房间所要求的基准温度和相对湿度。
空调精度－-指空调房间的X区域内空气的温度，相对湿度在要求的连续时间内允许的波动幅度。
凡是*t在1℃以上的空调系统叫一般精度的空调，一般精度的空调系统可以通过手动来控制。 当*t=±1℃的空调系统宜做成自动控制。
当*t小于1℃的空调系统叫高精度空调系统，应采用自动控制 空调系统按空气处理设备的集中程度为几类？
集中式空调系统－-所有的空气处理设备全部集中在空调机房内，根据送风的特点，它又分为单风道系统，双风道系统和变风量。半集中式空调系统－-除了安置在集中的空调机房内空调处理设备之外，还有分散在空调房间内的空气处理末端设备，如风机盘管等设备。
局部式空调系统或全分散空调系统－-即空调机组（又称空调器），这种机组的冷热源、空气处理设备，风机和自动控制元件，全部集中在一个箱体内。 空调环境的舒适条件 Recovery of central air conditioning market in Xiamen, Xiamen buy scrap central air conditioning, central air conditioning recovery 13606035861 Xiamen used central air conditioning recovery, recycling Shanghai central air conditioning, central air conditioning scrap recycling.
Air conditioner cooling capacity is the air through the evaporator, the surface cooler, water cooling chamber after the desired cooling capacity. Cooling load is air-conditioned room to maintain a certain temperature and humidity parameters, excluding interior heat, I wet the required cooling capacity. In a stable condition, the air conditioner cooling capacity equal to the cooling load, air supply pipe cooling loss and exhaust loss and cooling capacity. What is the dew point temperature? What is the dew point temperature of the machine?
The water volume in the air (moisture content) remain unchanged, while the saturation temperature by cooling when the temperature is called the dew point temperature. Air dew point temperature, relative humidity of 100%, when the dry bulb temperature, wet bulb temperature, saturation temperature and dew point temperature is the same temperature. In the air-conditioning technology, when the air through the cooler or spray room, some direct contact with the wall or chilled water saturated bear dew, but there are a considerable part of the cold air source is not in direct contact, although heat exchange and cooling has also been, but they are in the relative temperature of about 90 ~ 95%,
At this time the state of temperature is called the dew point temperature of the machine. What is air conditioning, air base and air conditioning accuracy? Air-conditioned air-conditioning is referred to, is to make the indoor air temperature, humidity, cleanliness and air speed (referred to as four degrees) to keep within a certain range of an environmental engineering, he was comfortable and the production process to meet the two major categories of requirements.
Air base - is the basis required by air-conditioned room temperature and relative humidity.
Air conditioning Accuracy - refers to the effective area air-conditioned room air temperature, relative humidity within the required time to allow continuous fluctuations.
1 ℃ * t all over in the air conditioning system called the general accuracy of the air-conditioning, general accuracy of the air conditioning system can be manually controlled. When * t = ± 1 ℃ in the air-conditioning system should be made of automatic control.
* T less than 1 ℃ when the air conditioning system called precision air-conditioning system, automatic air conditioning system should be adopted by the concentration of air handling equipment for the several categories?
Central air conditioning systems - all of the air handling equipment are all located within the air-conditioned room, according to the characteristics of air, it is divided into single duct system, dual-duct system and variable air volume. Semi-centralized air conditioning system - in addition to placement in a centralized air-conditioning air handling equipment within the room, there are also scattered in the air-conditioned room air handling terminal equipment, such as fan coil units and other equipment.
Local air conditioning system or air conditioning system wide dispersion - the air conditioning unit (also known as air conditioners), this unit of heat sources, air handling equipment, fans, and automatic control device, all in one cabinets. The comfortable air-conditioned environment conditions
