[Air conditioner water machine and fluorine machine] The difference between central air conditioning water machine and fluorine machine Comparison of central air conditioning water machine and air duct machine
What is the difference between a water machine and a fluorine machine? The demand for household central air conditioners is rapidly increasing.
Household central air conditioners are divided into fluorine systems and water systems, that is, what we often call fluorine machines (also called air duct machines) and water machines. Both the fluorine machine and the water machine occupy a large market share, so many people do not know whether to choose a central air-conditioning fluorine machine or a central air-conditioning water machine. Let’s compare the central air-conditioning fluorine machine and the water machine to analyze the choice for everyone. what kind of system.
Central Air Conditioner Water Machine
Central Air Conditioner Fluorine Machine
Energy Efficiency Ratio
Suitable for large-area use, the greater the utilization rate, the more energy-saving (the heat capacity of water is relatively large)
Small apartment use (frequency conversion technology, which is advantageous when the usage rate is low)
Comfort
Moisture is not easily lost, and the temperature gradient is small
Indoor air is dry and uncomfortable after long use
Circulation system
Water machine (water circulation system)
Fluorine machine (refrigerant circulation system such as Freon)
Radiation
No high frequency harmonics, excellent electromagnetic compatibility, zero interference to electrical equipment.
High frequency electromagnetic harmonics, radiation. Interference with human body and precision electrical appliances
Reliability
Dual circuit design, multiple compressors, even one compressor circuit Failure can still continue to work, reliable scroll compressor, long operating life of the unit.
An inverter compressor, the control of the outdoor unit and the indoor unit are all connected, once a unit fails, The whole system cannot be used, there is only one compressor, which needs to run for a long time.
Safety
The refrigeration system is centralized in the external unit, safe and reliable
Refrigerant spreads all over the system, and the probability of leakage is high
Service life
The design life of the water machine is 20 years
The fluorine machine is 15 years
After-sales service< p align="center" style="text-align:center;background:#E8F4FF;"> The performance is relatively stable, and the later maintenance cost is low.
It was used well in the past few years, but it is prone to problems after 7-8 years, and the maintenance cost is high.
Heating effect
The heating range of the water system can be -10℃, and the water system can be supplemented by a wall-hung boiler
Fluorine system heating is poor below -5℃
Thermal efficiency
Heating up slowly
Heating up quickly

Comparison of household central air conditioners – water Comparison of fluorine machine and fluorine machine
Through the comparison of central air-conditioning fluorine machine and water machine, it is not difficult to find that the biggest difference between central air-conditioning fluorine machine and central air-conditioning water machine lies in comfort and thermal efficiency. It should be determined according to personal usage habits, but from the perspective of future trends, the central air-conditioning water machine has a broader prospect than the fluorine machine, and is more in line with the positioning of the future comfortable home system.
Comparison of central air conditioner water machine and air duct machine
1. The water machine is more comfortable.
2. The water machine is more environmentally friendly.
3. The water machine truly controls the temperature of each room independently, and saves electricity, while the air duct machine controls the temperature through the air valve, giving the user an illusion that the compressor has stopped. In fact, the compressor has not stopped. Therefore, the fan consumes a lot of power. The comprehensive cost of using the water machine is very low, and the cost of using the air duct machine is very high.
4. The air in each room of the water machine is circulated independently, while the air duct machine is a cross-mixing of the air in several rooms, blowing air from each other and infecting each other, so use the air duct machine to smoke less , Eat less stuffed with chives, maybe the quilt in your bedroom will smell like mutton in a restaurant!
5. Privacy, the air duct of the air duct machine itself is also a sound transmission channel. If adults watch TV, listen to music, chat, play mahjong at night…it is easy to disturb the child’s rest.
6. The water machine can drive a large air-conditioning area with a small air-conditioning host (small total power), and the air duct machine must not be small and large, and must be distributed to the large cooling capacity , otherwise you will file a lawsuit in the summer. Therefore, it is recommended to choose a water machine, especially a variable frequency water machine, for a villa with a small total meter power. The starting current is very small, the gate does not drop, and it is the most power-saving and occupies less power value of the meter. If the commercial and residential dual-use room is used for office, you should use the frequency conversion water machine, so that your computer, copier, printer, lighting and other equipment will have electricity available. Otherwise, you can ask the power supply bureau to increase the capacity.
7. The distribution of the air volume and cooling capacity of the air duct machine is a headache for all experts in the household field. Some rooms are either cold to death, some rooms are too hot, and the air volume distribution is disproportionate. This is The duct machine has it in the womb.
8. The sound of the return air of the air duct machine is loud (high noise). Concentrating the air volume required by several rooms on one machine (indoor unit), can the noise and darkness be small? The water machine just distributes the air volume required by each room to the fan coil unit of each room, and the sound is quiet.
9. The water machine and the gas stove are used together. The air-conditioning water and the heating water share a system. The radiator is removed, which saves a lot of heating costs. The heating fee for the radiator and the gas stove is generally one winter. It costs 30 yuan to 45 yuan per square meter per square meter, while the gas furnace water heater is generally 15 yuan to 22 yuan per square meter. This technology has a history of decades and is a very mature technology. The air duct machine plus the gas furnace is defective in the heating control of the building, so this solution cannot be used.
10. The water machine can bring as many rooms as you want, but once the air duct machine brings multiple rooms, its return air cannot be solved. Be sure to remember: material is conserved, and there must be return air if there is supply air.
11. The air duct machine is very suitable for the use of independent large rooms, such as the halls of shopping malls and restaurants (but the private rooms are suitable for water machines), these public independent large spaces are used, and the price is cheap. If it is a large room, in which you work and operate, it is recommended to use a duct machine.
12. The air duct machine is cheap and the water machine is expensive. This is the disadvantage of the water machine.
