Multi Split Air Conditioner
You know understand what’s the difference between a multi-split air conditioner and a monoblock system ? There are many competing types of air conditioners on the market, each with its own advantages and disadvantages, but their role is of course to improve everyone’s summer comfort by diffusing cool air. In this article, we will give you all the information you need about the multi-split air conditioner, how it works and its strengths.
What is a multi split system air conditioner ?
The first thing you need to know is that a split air conditioner consists of two units: one indoor, the other outdoor and has a reversible system in most cases, so it lets out cool air in summer and warm air in winter, the device of choice for thermal comfort.
So a mono-split unit consists of an indoor unit and a reversible air conditioning unit. In fact, the multi-split air conditioning has several units, which allows to supply several rooms at the same time. On the other hand, an all-in-one air conditioner consists of a single indoor unit, which allows hot air to be exhausted through a duct connected to an outdoor opening. Finally, ducted air conditioners are often hidden in false ceilings and emit cool air through a blower outlet. However, multi-split reversible air conditioners can be composed of 2, 3 or 4 outdoor units, and can be called double split, triple split or quad split. This makes it possible to distribute cold or hot air to several rooms in the house, while having to carry only one outdoor unit. Therefore, this air conditioning system is ideal for ventilation and cooling of large homes.
A multi-split air conditioner can come in many forms. It can be a wall-mounted unit like a radiator, a ceiling-mounted unit, a recessed cassette unit or a wall-mounted, overhead system.
How does a multi-slit air conditioning system work ?
The operation of reversible air conditioners is similar to that of an air-to-air heat pump (thermal system), which draws indoor air to the outside through refrigerants that allow heat exchange, and the air conditioner consists of one or more indoor units. More precisely, four elements allow the proper functioning of the heating and air conditioning equipment, namely: compressor, condenser, expansion valve and evaporator. The latter are integrated into the indoor units to capture the calories present in the air and transfer them to the refrigerant.
This fluid arrives at the compressor in the form of vapor, which is then sent to the condenser, which acts to evacuate the heat accumulated in the circuit, whose temperature oscillates between 50 and 70 degrees. Once this heat is removed, the fluid can cool down to its condensation temperature, bringing it back to a liquid state. This is where the regulator comes into play: this component lowers the pressure in the circuit, which in turn lowers the temperature of the fluid, thus cooling the component. If the air conditioner is reversible, the unit will also be equipped with a recirculation reversal valve to switch from cold to hot and vice versa. Finally, there are service valves to store refrigerant, add or remove refrigerant and control the pressure of the circuit.
Inverter technology on some units is used to increase the COP (Coefficient of Performance) and save money. Without it, the compressor will run until it reaches the desired temperature, then shut down completely. Then restart when the temperature rises, and so on. Inverter technology, on the other hand, compensates for temperature variations, using a compressor developed by Mitsubishi Electric. This provides plenty of power when you need it and slows it down when you don’t. As a result, the air inside is drier and more comfortable.
The advantages of multi-split air conditioners
Split air conditioners also have the advantage of being relatively quiet compared to other systems, thanks to the ducts hidden in the walls. Therefore, their noise level is reduced compared to, for example, a single-package air conditioner. Another advantage is that it is a very responsive system and very easy to operate. In heating mode, it reaches a comfortable temperature much faster than a cast iron radiator. Multi-split reversible air conditioners have a high coefficient of performance because they provide more energy than they consume. These air conditioners use less energy to optimally cool each individual room. Each room can have its own comfortable temperature, but not with a single split air conditioner. Multi-split air conditioners have many advantages, and if they are reversible, you can enjoy comfortable temperatures all year round. It’s easy to use, and you need a qualified installer to install it and enjoy all its benefits! The multi-split air conditioning system consists of several units, so it can operate in several rooms at the same time. Often reversible, the air conditioner can cool in summer and provide additional heating in winter. Multi-split air conditioning systems can be designed as a wall-mounted console, a ceiling-mounted unit, a recessed cassette or a wall-mounted system.
How does this air conditioner system work ?
It works in a similar way to a heat pump that draws air from the room and sends it outside. Inverter technology is integrated in some units to improve the COP and save energy.
