There are two rows of cabinets 103, which are respectively arranged against the bulkheads on both sides in the width direction of the cabin body 102, and there is an aisle between the two rows of cabinets 103. The prefabricated cabin temperature control system includes two industrial air conditioners 101. The industrial air conditioners 101 are air conditioners using a fresh air air conditioning system, and are in the form of upper air outlets. The temperature adjustment devices include a compressor refrigeration system and a fresh air system. The fresh air system is an existing technology, which can transport the outside air into the cabin after being filtered, and its specific structure will not be described in detail here.

The temperature sensors include an internal sensor and an external sensor which are respectively arranged inside and outside the prefabricated cabin.

Among them, the action of the control device to only start the fresh air system and shut down the compressor refrigeration system is triggered when the temperature detected by any internal sensor > T2, and the set temperature T0 is the temperature that can ensure the normal operation of the equipment in the prefabricated cabin. In this embodiment, T2 is set at 25°C, and T0 is set at 20°C.
预制舱使用时，预制舱温控***具有以下工况： When the prefabricated cabin is used, the temperature control system of the prefabricated cabin has the following working conditions:
工况一：当三只内部传感器检测到的内部温度均小于20℃时，工业空调101处于待机状态，改变了现阶段工业空调不管预制舱内部的气温如何，内部风机一直在运行的现状。 Working condition 1: When the internal temperature detected by the three internal sensors is less than 20°C, the industrial air conditioner 101 is in the standby state, which changes the current situation that the internal fan of the industrial air conditioner is always running regardless of the temperature inside the prefabricated cabin.
工况二：在外部传感器检测到的外部气温低于25℃，至少一只内部传感器检测到的内部温度高于25℃，此时，工业空调启用新风功能，直接将户外的新风通过过滤棉后引入到预制舱，完成对预制舱内部的机柜的制冷，这个制冷过程没有启动压缩机，电能消耗比较少，达到节能的目的。 Working condition 2: When the external air temperature detected by the external sensor is lower than 25°C, and the internal temperature detected by at least one internal sensor is higher than 25°C, at this time, the industrial air conditioner activates the fresh air function and directly passes the outdoor fresh air through the filter cotton. Introduced into the prefabricated cabin to complete the cooling of the cabinets inside the prefabricated cabin, the refrigeration process does not start the compressor, the power consumption is relatively small, and the purpose of energy saving is achieved.
工况三：至少一只内部传感器检测到的内部温度高于25℃，预制舱外部的气温也达到了25℃时，停止新风制冷，启动压缩机进行预制舱的制冷，此时空调的耗电量最多。 Working condition 3: When the internal temperature detected by at least one internal sensor is higher than 25°C and the temperature outside the prefabricated cabin reaches 25°C, the fresh air cooling is stopped and the compressor is started to cool the prefabricated cabin. At this time, the power consumption of the air conditioner is The largest amount.
这样，通过不同工况对应不同的散热方案很好地实现了节能的目的。 In this way, the purpose of energy saving is well achieved through different heat dissipation schemes corresponding to different working conditions.
在上述实施例中，内部传感器设有三只，工业空调设有两台。在本实用新型的其他实施例中，内部传感器也可以仅设置一只、两只或四只以上，内部传感器的安装位置也可以根据需要替换为其他形式，而工业空调的数量和设置位置也可以根据需要进行调整。 In the above embodiment, there are three internal sensors and two industrial air conditioners. In other embodiments of the present utility model, only one, two or more than four internal sensors can be provided, and the installation positions of the internal sensors can also be replaced with other forms as required, and the number and installation positions of industrial air conditioners can also be Adjust as needed.
