17.7 Temperature Mapping
The purpo of temperature mapping helps confirm that the area as a whole remains within its defined limits and determine the locations reprenting temperature extremes within the area
温度分布的目的是证实该区域整体仍在其既定的限度范围内并确认区域内的极端温度位置点。
The cond objective defines the locations for permanently installed nsors that provide data for the quality system of record for the area, the information from which the MKT is calculated (if required).
第二个目的是规定用于长期安装，提供该区域质量系统记录的传感器的位置，记录中同时会有MKT的信息（如果需要）。
There is very little guidance on temperature mapping, the French Standard, (NF X15-140 October 200
2 “Measurement of Air Moisture –Climatic and thermostatic Chambers- Characterisation and Verification”) (Reference 11, Appendix12) provides some guidance on nsor locations to be ud for mapping of environmental chambers, as summarized below.
关于温度分布的指南非常少，法国标准（NF X15-140 October 2002 “Measurement of Air Moisture –Climatic and thermostatic Chambers- Characterisation and Verification”）（附件12，参考11）中提供了一些环境测试室温度分布探测器点位置的指南，总结如下。
The method is bad on the size of the chamber and the area potentially occupied by product. For chambers over 700 cubic feet (20 cubic meters), the standard suggests considering the factors that may affect the specific installation, including:
door openings
●location of cooling system
●position of the control nsor
（确认传感器位置的）方法是基于房间的尺寸和产品可能占用的区域。比如超过700立方英尺（20立方米），该标准建议考虑一些影响特定安装的因素，包括：
●开门汉普森英语
●制冷系统位置
●控制传感器的位置
傲慢与偏见电影台词Figure17.6 is bad on the French Standard (Reference 11, Appendix 12). The drawing on the left shows the minimum number and suggested location of nsor locations mounted in the working area for a chamber up to approximately 70 cubic (cubic meters). For bigger areas, up to 700 cubic feet (20 cubic meters), the standard suggests using as a minimum the number and location of nsors shown on the right hand drawing. The number of nsor locations suggested should be incread as necessary to monitor, for example, conditions for product located near a conditioned air discharge or the door, as well a nsor located near the temperature control nsor.
图17.6来自于法国标准（附件12，参考11）。左边的图给出一个将近70立方英尺（2立方米）的房间中工作区域内传感器的最小数量和建议的安放位置。如果是更大的区域，比如700立方英尺（20立方米），该标准建议参照右边图中的最小传感器数量以及安放位置。建议的传感器位置数量可以根据监测的需要增加。比如，靠近经空调处理过的空气出口或门的产品位置，同样，在温控传感器旁边也可以放置一个传感器。
Note: The inner box reprents the working area (where product is stored); the dots reprent the nsor locations.
剩余价值的生产过程备注：里面的方框表示工作区域（产品存放的区域），圆点表示传感器位置。
unknowingWhile not directly relevant, the guidance provided should prove helpful – distances between nsors depend on the local conditions and influences, such racking layout, positions of the HVAC outlets, doors, internal and external walls, etc. An approach that has been ud with some success is to consider the area around each HVAC outlet as a zone and apply the logic suggested in the right hand drawing shown above with a nsor adjacent to the temperature control nsor as well as others monitoring the supply and return temperatures.
虽然没有直接关系，提供的指南应证明是有用的-传感器之间的距离取决于当地的条件和影响，例如货架布局、HVAC出风口位置、门、内墙及外墙等等。一种可行的方法是将每一个HVAC出风口的周围区域都作为一个区，并按照上图右边所示放置传感器，其中温控传感器附近放置一个传感器，同样，其他传感器也需要监测到送风和回风的温度。
For an area bounded by an external wall, the area requires mapping in the asonal extremes in order to determine the influences of heating and cooling supply temperatures from the HVAC system, and the heating or cooling effect of the external walls and roof adjacent to the racking. The strategy developed for this asonal testing should consider
the effects, becau of empty and full racking, the effects of the thermal mass/insulation/airflow chan
ges. As an example, Figure 17.7 shows a potential mapping layout with one part of the room full of product and one part empty – a simple approach in this instance as the layout is symmetrical.
对于一个有外墙分界的区域，该区域需要在极端的气候条件下进行温度分布试验，以确定HVAC系统供热和制冷的影响以及靠近外墙和屋顶的货架冷热影响。对于季节性的测试，先进策略应考虑这些影响。由于空的和满的货架会影响到热质量/隔热/气流的改变。举例来说，图17.7展示一种温度分布布局，房间的一部分放满了产品而另外一部分是空的。这个例子是一个简单的应用，因为布局是对称的。
Other factors that should be defined before testing include:意大利语在线翻译器
●Product temperatures – if upon delivery the are significantly different from the
defined storage conditions, the product may require monitoring to determine how long it remains outside the defined storage conditions.四级各项分数
●Loading and unloading – will the product be at a different temperature, how much is
loaded/unloaded at any one time, will there be a significant ingress/egress of conditioned air, replaced by unconditioned outside air from outside?
●Is there an outside door that can be left open or is it monitored to a defined maximum
time that it could be open?
●Storage locations nearest the heating /cooling system inlet/outlet
最长的英语单词●Internal loads – lighting, equipment, and personnel
●Conditions during minimum (empty) and full storage capacity
其他测试前必须确定的因素，包括：
●产品温度– 如果在运输上显著不同于既定的储存条件，那么产品需要进行监测以确定
在规定的储存条件以外的保持时间
怎样才能增强记忆力●负载和空载– 产品是否会在一个不同的温度？负载和空载在任一时刻的比率是多少？
是否有相当一部分出口或进口经空调处理的空气会被外部空气置换？
●门是否会保持对外敞开？或者开门的最大时间经过监测并被确定？
●最靠近加热或制冷系统出口或进口的储存地点？
●内部负载– 照明、设备以及人员
●最小（空的）和最大储存容量的条件
Ideally the factors will be reviewed and considered with a reprentative test method defined. An example is included below:
Example Plan:

External Heat Gains and Loss
bulge
The major heat gains and loss to the cold room are due to the influences of the external environment with the most significant being through the walls and ceiling.
Internal Heat Gains and Loss
Lighting – the lighting is from low energy fluorescent lamps that are left on during the working day.
Product – the product stored in the room is supplied at the storage temperature and will not reprent additional load to the room
Equipment – the equipment ud in the room is a stacking fork truck – a relatively small intermittent load.
People – there are 2 people occasionally working in the area; therefore, the heat gains are small and transient.
HVAC – the room is conditioned through two registers mounted as shown with a common return air grille located at high level in the center of the room.
理论上，这些因素应用过一个有代表性的测试方法确定，下面举个例子：
