At present, domestic central air conditioning systems are mainly divided into three categories: one-drag-one-fan system, multi-line fluorine system and air-cooled cold and hot water system. These three systems have their own characteristics, and car owners can choose according to their actual needs when choosing!
A, the type of household central air conditioning-duct air supply system
Pipeline fan, also known as air-cooled pipeline system, is mainly composed of indoor unit, outdoor unit and pipeline. An indoor unit corresponds to an outdoor compressor, which is a one-to-one independent configuration system, and mainly uses the condenser of the outdoor unit for air cooling to adjust the indoor temperature. The main advantage of the duct fan system is that the initial investment is relatively low, and each room can be controlled independently. The disadvantage is that it may not be as good as the performance of frequency conversion and multi-connection in comfort and temperature adjustment.
Second, the type of household central air conditioning-multi-online system
The so-called multi-connected system is the most common household central air conditioner on the market at present, also called one-tow multi-fluorine system central air conditioner. An outdoor unit can be connected with multiple internal units for operation. The outdoor unit is mainly composed of compressor, heat exchanger, electronic expansion valve and other components. It mainly uses the control of compressor refrigerant flow to adjust the indoor temperature, and the indoor mechanism is mainly composed of evaporative heat exchanger, fan and other components. At present, many on-line machines in the market adopt frequency conversion technology, such as Panasonic central air conditioner, which adopts full DC frequency conversion technology, which has more advantages in energy saving and temperature regulation and better comfort!
Three, the type of household central air conditioning-air-cooled, cold and hot water system
Air-cooled cold and hot water system is usually called water system central air conditioning, which is mainly compared with fluorine system. All indoor loads are borne by the cold and hot water units, and the fan coil units in each room are connected with the cold and hot water units, which are delivered to each room by tap water to realize temperature regulation. Water system has many advantages, such as flexible control, very high comfort and good independent temperature control.
The above are the main characteristics of central air conditioning in each system. If you have any other questions, you can Baidu Hunan Tianlan Environment, and our professional central air-conditioning designer can answer them for you!
