1. The principle of air conditioning refrigeration. After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked into the compressor and compressed into high-pressure steam and then discharged to the condenser.At the same time, the outdoor air inhaled by the axial fan flows through the condenser, taking away the heat released by the refrigerant, so that the high-pressure refrigerant steam condenses into a high-pressure liquid.
2. After the host refrigeration, it is sent to the combined air cabinet. The air is cooled by the combined air cabinet and sent to the required place. The principle of host refrigeration such as screw machines and air cooling modules is the same as that of household air conditioners. The only difference is that the water is cooled after cooling, the water is circulated to the end, and then the air is cooled, and the air is sent to use Household.
3. Working principle: Air conditioners are divided into single-cooled air conditioners and dual-use air conditioners for cooling and heating. The working principle is the same. Most of the refrigerants commonly used in air conditioners were Freon. The characteristic of Freon is that when it changes from gas to liquid, it releases a lot of heat. And when it changes from liquid to gas, it will absorb a lot of heat.
4. The structure of the central air conditioning system is shown in Figure 5-1.According to its working principle, it can be divided into four parts: refrigerator unit, cooling water tower, external heat exchange system and cooling fan.
5. The full air system is a combination of a variety of equipment such as indoor air conditioning, heating, fresh air, dehumidification, humidification, air purification, air sterilization, etc., and takes the health system as the standard, and the computer accurately adjusts the whole air control logic.
That is to say, no matter how many partitions the hard disk has, its main boot record only contains the information of the main partition (i.e. the boot partition) and the extended partition.
In fact, it is the area on the hard disk, such as a 500G hard disk, which is usually not regarded as an area for ease of use.The domain is used, because the computer needs to be bought back to install the operating system. If it is used as a partition, when the computer is poisoned or the system needs to be reinstalled, all the data on the entire 500G will be deleted, which is not what we expect.
Computer disk partitioning refers to dividing the storage space of the computer hard disk into multiple independent areas. Each disk partition sets up a corresponding function area to store the operating system, applications and data files according to the corresponding disk partition.
Disk division is a hard disk partition to create multiple independent logical units on a physical hard disk. These logical units are C disk, D disk, E disk, etc. Hard disk partitioning is essentially a kind of formatting of hard disk. The steps are as follows: right-click My Computer, and then select Disk Management.
1. The system is flexible and easy to change and expand, especially suitable for buildings with variable patterns.
2. The advantages of the single air duct system are simple equipment, relatively economical initial investment, centralized equipment setting, and easy management.The disadvantage is that when a centralized system supplies multiple rooms, and the load changes of each room are inconsistent, it cannot be accurately adjusted. In addition, the cross-section of the air duct is large and occupies a large space.
3. Fixed air volume dew point air delivery double air duct air conditioning system Working principle: Figures 6-20 are a fixed air volume double air duct (dual parameters) system. There are two air delivery channels, which deliver cold air and hot air respectively. Cold air and hot air are mixed in a certain proportion in the mixing box of each room and sent into the room.
1. Create separate partitions for the operating system First, we need to create separate partitions for each operating system. Partitions can divide the hard disk into different parts, and each part runs a different operating system independently.You can create partitions by opening the disk management tool of Windows or using other disk management tools.
2. Install the second operating system: start the computer with the installation media (such as CD-ROM or USB drive) and follow the prompts of the installation wizard to install the second operating system. During the installation process, select the newly created partition for installation. Configure the startup sequence: After the installation is completed, restart the computer.
3. Prepare the installation media: First, you need to prepare the installation media for the two operating systems, such as the installation CD or USB boot disk of Windows and Linux. Partition hard disk: Before installation, you need to allocate enough hard disk space for each operating system. You can use the disk management tool to adjust the partition size or create a new partition.
4. To install two operating systems on one computer at the same time, you can follow these steps: Prepare the installation media: You need to prepare the installation media for the two operating systems, such as the installation CD or USB drive of Windows and Linux. Partition hard disk: Divide the hard disk into two or more partitions before installation.
