1. Is it worth buying a single outdoor unit air conditioner?
Recently, the market has been buzzing about the single outdoor unit air conditioner, connected to multiple indoor units from famous brands like Panasonic, LG, Daikin, Mitsubishi... The standout feature of this air conditioner line is its energy-saving capability.
According to investigations, manufacturers refer to this air conditioner line as multi-split systems. Depending on the outdoor unit's capacity, customers can connect 2-5 indoor units in different rooms. Instead of installing a separate air conditioner with an outdoor unit for each room, with this system, you only need one outdoor unit connected to indoor units placed in bedrooms, living rooms, kitchens... effortlessly. However, selecting the appropriate outdoor unit capacity according to the area of use is essential to meet the required cooling level. If the outdoor unit's capacity does not match the maximum usage needs, if all indoor units operate simultaneously, it will not guarantee sufficient cooling capacity for each indoor unit. Each indoor unit will experience a corresponding reduction in cooling due to the system's capacity modulation for each indoor unit.
'Due to the relatively high cost of multi-split outdoor units, during installation, technical teams from companies often advise customers in a way that cuts costs. For example, a house with 2 bedrooms and 1 living room should ideally choose an outdoor unit with a capacity of 4HP, but customers might end up purchasing a unit with only 2HP or 3HP capacity and still meet their usage needs since it's rare for all 3 rooms to use the air conditioner simultaneously. However, if all indoor units are used at the same time, the outdoor unit must continuously operate at full capacity, leading to high electricity consumption and potential machine damage' - a technician revealed. Business experts highlight the advantage of multi-split air conditioners in that fewer outdoor units need to be installed. The fewer indoor units used in rooms, the quicker and higher the cooling capacity achieved since the outdoor unit has excess capacity. Multi-split air conditioners have higher installation costs compared to conventional ones if customers only need to install 1-2 indoor units, but they are economically efficient for households requiring multiple air conditioners. Nevertheless, the inconvenience of this air conditioner line is that if the outdoor unit malfunctions, all indoor units in all rooms will be affected. Additionally, repairing multi-split air conditioners can be costly as it requires technicians specialized in this type of system, whereas technicians repairing conventional air conditioners may not be familiar with newer models, causing difficulties. Furthermore, repair components are not widely available, with most being genuine parts, thus commanding high prices.
