A duct machine is actually a duct type air conditioner. It generally includes two parts: an indoor unit and an outdoor unit, which are connected to each other through copper wires. When operating a duct machine, the outdoor unit first supplies the air The air supply duct is drawn in, and the air supply duct is connected to each room, and then the air drawn in is cooled and sent out through the air supply duct. Central air conditioning is the general term for centralized and semi-centralized air conditioning. The central air conditioning system includes chillers, chilled water circulation systems and cooling water systems; the central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. The system centrally processes air to meet comfort requirements.

What is a duct machine?

Duct air conditioners are actually duct air conditioners. They generally include two parts: an indoor unit and an outdoor unit, which are connected to each other through copper wires. When the air duct machine operates, the outdoor unit first draws air into the air supply duct, which connects each room, and then the air drawn in is cooled and sent out through the air supply duct. In addition, the indoor unit can also draw indoor air into the air supply duct, cool it, and mix it before sending it out. This simple operation method is also the cheaper way of air duct machines, so we can often see such air duct machines in ordinary families.

Advantages and Disadvantages of Duct Machines

Of course, duct machines also have their own advantages and disadvantages. The advantages of the air duct machine are very obvious. In addition to the low price mentioned above, the air duct machine also has a very fashionable appearance. The appearance design is also the focus of the air duct machine manufacturing. Secondly, when repairing the air duct machine, we do not need to find a professional air conditioning repairman, we can just do it ourselves. Finally, duct fans are very suitable for installation in rooms with relatively large spaces, such as hotel lobbies, shopping malls, etc.

Of course, the air duct machine also has its own shortcomings. The fixed frequency technology of the air duct machine often makes us think that the compressor inside the air duct machine has stopped, which causes the air duct machine to consume too much power. In addition, the noise of air duct machines has long been despised by people, and these noises often affect our normal rest. As mentioned earlier, duct fans are more suitable for larger spaces, but they are definitely not suitable for rooms with smaller spaces. Although this problem can be solved by installing multiple outdoor units, it is also very troublesome and will also affect the appearance of the home.

What is central air conditioning?

Central air conditioning is the general term for centralized and semi-centralized air conditioning. The central air conditioning system includes chillers, chilled water circulation systems and cooling water systems.

Generally refers to an air conditioning system that supports multiple air outlets (multiple rooms, multiple locations).

The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. This system is different from traditional refrigerant air conditioners (such as single units, VRV) and centrally processes air to achieve comfort. Require. The principle of liquid gasification refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cooling and heating load of the indoor environment.

The refrigeration system is a crucial part of the central air-conditioning system. Its type, operation mode, structural form, etc. directly affect the economy, efficiency, and rationality of the central air-conditioning system in operation.

Advantages and Disadvantages of Central Air Conditioning

Advantages: high comfort, less noise at cooling speed than ordinary air conditioners, energy saving and environmental protection, and more economical use Electricity; beautiful appearance, because they are installed separately during installation, so they can be hidden and matched with furniture.

Disadvantages: The installation and maintenance costs are higher than ordinary ones because they need to be hidden; it is difficult to repair.
