Types of household central air conditioners
Commonly used household central air conditioners can be roughly divided into three types: air-cooled piping systems, air-cooled cold/hot water systems, and multi-connected systems.
Air-cooled piping system:
Advantages: The air-cooled ducted central air-conditioning system is cheaper, the air-conditioning system can be equipped with fresh air devices, and the management and maintenance of air-conditioning equipment is more convenient.
Disadvantages: The air-cooled ducted central air-conditioning system is not easy to adjust the temperature and humidity of each room, and the ducts take up a certain amount of space. When designing, the layout of the supply and return ducts will be the most difficult thing in the design. At the same time, pay attention to the air system Distribution problems to avoid uneven air supply
Air-cooled cold/hot water system:
Air-cooled hot and cold water unit, as the name implies, air-cooled means that the condenser is cooled by air, and the hot and cold water means that the unit can produce hot and cold water; it is the most common household water central air conditioning system in the family.
It generates air-conditioning cold/hot water through the outdoor host, which is delivered to each terminal device in the room by the pipeline system, where the cold/hot water exchanges heat with the indoor air to generate cold/hot air, thereby eliminating the room air conditioning load. It is a form of centralized generation of cold/heat and decentralized processing of air conditioning systems in individual rooms. The terminal device of the cold/hot water unit is usually a fan coil.
For this kind of system, you don't need to say more about Refrigeration Encyclopedia, most of them know. This is the VRV variable refrigerant flow system, which is a refrigerant type air-conditioning system, especially suitable for office spaces.
One outdoor unit of the VRV system can deliver refrigerant liquid to several indoor units through pipelines. By controlling the refrigerant circulation of the compressor and the refrigerant flow entering the indoor heat exchangers, the indoor cooling and heating load requirements can be timely met. The VRV system has the advantages of energy saving and high efficiency, and each room can be adjusted independently to meet the needs of different air conditioning loads in different rooms.
