In the previous phase, we introduced the construction and composition of the air conditioning and cooling system in the data room. For more information about BKJIA, see: serialization: system composition of basic knowledge about air conditioning in the data room ), what we bring to you today is the basic components of the compressed refrigeration system, including the evaporator, condenser, evaporator, expansion valve, and circulation process. If you
further understanding of the signal can be transmitted to confirm. The parameters listed above, which are required by BAS to complete the control, do not imply that any chiller host will provide these process parameters. So from the system configuration and system integration requirements, the monitoring point of BAS must be added to the data communication parameters. Especially because this system is variable once flow (variable frequency speed control refrigeration pump) control, the evaporat
electricity with tropical cable corresponding to the heating system with automatic adjustment of output power, so it will not be burned due to their own heat, but due to the actual need for heat compensation, so for the next generation of energy-saving thermostatclosed-type cooling tower, evaporative condenser, air cooler, quick-freezing equipment, cooling devices and other equipment to our life has brought greater convenience, but we should also pay
perennial months of the room to send the wind.Cleaning Step two: Gently push upward, remove the screenYou must be curious about where the smell of air conditioning comes from, and you must be aware of the built-in filter.Here is the cleaning screen.Rinse the screen back with water and the dust will fall off automatically.When cleaning the condenser, we need to pay attention to, do not splash the cleaning liquid outside the air-conditioning parts, esp
situation changes if the structures are illuminated from the side and viewed in front of as dark a background as possible. the structures then really seem to light up.
Fine structures become visible: The spider webs (left) are barely recognizeable in front of the bright background-a light green field in this case. the picture completely changes when a dark background-a dark forest-is chosen. the structure seems to light up (right ). in both cases, th

Starting with the Windows IoT Core 14986 release, Microsoft has added the Cortana voice assistant feature. Before, we could only use local speech recognition, and we needed to write the application to download it to the device. From now on, Microsoft has integrated the Cortana voice assistant from the system level, enabling users to start Cortana and interact with Cortana in real time with system settings. Let's try the process of using Cortana as a Windows IoT core device with Raspberry Pi.1. H

Outdoor machine suction, exhaust air vents do not accumulate items, try not to set up in the outdoor machine canopy, should be left to meet the space to facilitate ventilation, or it will make refrigeration to decline, serious when it will cause downtime.Air conditioning maintenance: ①, air conditioners best not to run long time.

Instead of connecting them together, the figure uses multiple VCC And Gnd symbols to make the circuit diagram clearer and more concise (VCC = volt current condenser, indicating the power supply voltage; Gnd = ground, ground can be simply understood as the connection to the negative power supply, and we use Gnd as the reference voltage, the Gnd vo
