Because ordinary air conditioners can generally only meet the cooling and heating needs of a room, central air conditioners that can meet the needs of large area temperature control are becoming more and more popular with many people. So in the central air conditioning products that have begun to gradually become popular, do you know what kinds of central air conditioning are divided into?

Simple duct machine one tow one

Configuration mode: one fixed-frequency outdoor unit + one fixed-frequency indoor unit

Configuration principle: The hot and cold air is sent to each room through the air pipe, and the outdoor fresh air is easily introduced. At the same time, the centralized treatment of air humidification is also easier, and it is an economical machine. The indoor unit model is small, and the decoration can be perfectly combined. User-friendly temperature control in each room; Can have a certain proportion of energy transfer, energy saving and air conditioning cooling and heating speed, good effect.

Advantages: Compared with other household small central air conditioning types, the initial investment of the duct system is small; The fresh air system improves air quality and human comfort

Disadvantages:

1, an internal machine corresponds to an external machine, the overall noise is too large

2, not like other central air conditioning is frequency conversion, high operating costs

3, the air duct shuttles through various rooms, requiring the ceiling to be concealed, and sometimes may destroy the lintel. Limited by height, home decor and ceiling

Free combination of multiple models one drag more

Configuration mode: one outdoor unit + two or more outdoor units

Configuration principle: multi-on-line system, that is, refrigerant flow system. As the name suggests, it is a refrigerant system, which uses compressed refrigerant as the transport medium, uses a compressor to drive multiple indoor units, and the outdoor host is composed of external heat exchangers, compressors and other accessories. The indoor unit consists of a direct evaporative heat exchanger and a fan. The refrigerant is sent from the outdoor unit to the indoor unit through pipes. The refrigerant flow in the pipes and the cooling flow into each indoor radiator are controlled to meet the heat and humidity requirements of rooms with different loads. The main difference with other refrigerant air conditioning systems is that the compressor adopts frequency conversion speed control, when the system is at low load, through the frequency conversion controller to control the compressor speed, so that the circulating flow of the refrigerant in the system can be changed, so as to automatically control the cooling capacity to meet the requirements of the general residential home air conditioning system only need to set a frequency conversion compressor.

Advantages: Can meet the needs of different rooms, energy saving, hot body comfort.

Energy-saving air conditioning hot water machine enjoy both air conditioning and hot water

Configuration mode: one outdoor unit + one pressure water tank + multiple indoor units

Configuration principle: The outdoor unit is generally called the hot and cold water unit, the indoor unit is generally called the fan coil, the outdoor unit and the indoor unit are connected through the water pipe, and the indoor air and water heat exchange to adjust the temperature. It generates air conditioning cold/hot water through the outdoor host, and is transported to the indoor end devices by the pipeline system. The cold/hot water at the end device exchanges heat with the indoor air to generate cold/hot air, thereby eliminating the air conditioning load in the room. It is a form of air conditioning system that centrally generates cold/heat and distributes the load of a room.

Advantages:

1, high precision temperature control, constant temperature, no hot and cold phenomenon, good comfort.

2, low running noise, but also your comfortable and quiet environment.

3, easy to coordinate and cooperate with interior decoration, reflecting elegant style.

4, the operation cost of the machine is low, even if only one room is used, because of the water temperature control switch, long downtime, will not waste electricity.

Disadvantages:

1, the water system installation, insulation requirements are high, professional team operation, to prevent water leakage problems.

2, the selection of water pipe material requirements are high, it is recommended to use PP-R pipe.

3, late maintenance trouble, auxiliary parts, system failure rate increased. If it is not maintained in time, the heat exchange efficiency is reduced, and the operating cost is greatly increased.

The above is about the types of central air conditioning related introduction, in general, central air conditioning is more suitable for villas, shopping malls, offices and other areas of relatively large space for installation, the general home, the use of ordinary forms of air conditioning is enough to bring warmth and cool for our living room.
