Choosing the Right AC System: Mini Split vs VRF Compared

System structure:

???Split air conditioner: consists of an indoor unit and an outdoor unit, usually used in one-to-one pairing, i.e. one outdoor unit corresponds to one indoor unit.

???VRF: consists of one or several outdoor units with multiple indoor units, which can control the temperature of multiple rooms at the same time and realize multi-point cooling/heating.

Scope of application:

???Split air conditioner: suitable for small spaces such as homes, small offices, stores, etc.

???VRF: suitable for large public buildings such as shopping malls, office buildings, hotels, hospitals, etc. or occasions where unified management of air conditioning systems is required.

Advantages

Split air conditioners:

1.Lower initial investment, ideal for those with limited budgets.

2. The installation process is easier, suitable for single room or small space, easy to move and install.

3. Individual installation of indoor units in each room will not affect the use of other rooms, effectively preventing cross-contamination. Especially during an epidemic, split air conditioners can avoid the risk of cross-infection like central air conditioners, especially for hotels, office buildings and shopping malls.

?

VRF:

1. Fewer number of outdoor units saves space and reduces safety risk.

2. Fewer number of outdoor units, easy to integrate with the building appearance, will not damage the overall aesthetics of the building.

3. Lower running cost, using advanced DC inverter technology.

4. Each room controls the indoor unit independently without affecting other areas, which also prevents cross-infection. It can be equipped with an independent fresh air system to improve indoor air quality completely.

5. The indoor unit can be installed in a hidden way, providing a variety of installation forms (e.g., four-side outlet cassette?unit, wall-mounted or duct unit), and the refrigerant pipe can also be installed in a hidden way, which perfectly matches with various indoor decoration styles and shows the user's personality and taste.

6. Indoor and outdoor connecting pipes can be laid over long distances to realize long-distance piping.

7. The VRF?system is easy to match with various centralized control systems, using microcomputer automatic control, each indoor unit can be switched independently to achieve individual or zoned temperature control of the room or area to enhance comfort.

8. The use of environmentally friendly refrigerant, reducing the impact on the environment.

9. Flexible adjustment of cooling and heating in the transition season, even at a low temperature of -20°C ?can also be stable operation of heating.

10. DC inverter scroll compressor is used to reduce the starting frequency, and the system is connected by copper pipes for longer service life.

11. Precise indoor temperature control, fluctuations are controlled within 0.5°C .

Disadvantages:

Split air conditioners:

1. Energy efficiency is relatively low and power consumption is high, resulting in higher operating costs.

2. There are restrictions on the length of piping, which is not suitable for long-distance installation.

3. It is more difficult to realize regional control and centralized control, resulting in uneven distribution of temperature and wind speed, affecting comfort.

4. Installing multiple split-type air conditioners in large areas or multi-room environments is inconvenient to operate and control, and too many outdoor units affect the aesthetics of the building, reducing safety, and maintenance difficulties.

5. Although the cost is low, it usually uses R22 refrigerant, which is harmful to the ozone layer and is not environmentally friendly.

6. It is difficult to operate in low temperature environment, and the indoor temperature control is not precise enough, and the fluctuation range can be up to 2 °C.

7. Usually not equipped with fresh air system, need to open the window for ventilation.

8. The indoor unit and refrigerant pipe cannot be installed in a hidden way, which takes up space and affects the aesthetics of the room.

9. The compressor is mostly rotor type, which shortens the service life due to frequent starting and stopping.

?

VRF:

1. The installation process is complicated, requiring professional design and piping layout, more suitable for large buildings or multi-room control needs.

2. Higher initial investment cost.

Suggestions:

1. Number of rooms: if the number of rooms in your home or office is small, a split unit may be more economical; if the number of rooms is large, it is recommended to choose a multi-connected unit.

2. Budget: when the budget is limited, split units are a more economical choice; when the budget is sufficient, multi-connected units can be considered.

3. Decoration: If the room has been decorated or you don't want to damage the decoration, split units are more suitable; if you have newly decorated or are willing to carry out remodeling, multi-connected units are better.

4. Habit of use: If you need to control the temperature of each room independently, multi-connected units are more suitable.

The final choice should be combined with your personal situation and use needs to decide. It is recommended that before making a decision, you can consult a professional air conditioning installation and maintenance company for detailed product information and professional advice.
