Several indoor units are connected to one outdoor unit of a multi-split system air conditioner. This is the main difference between multisplits and conventional split systems. Multisplits are chosen in cases where, for some reason, it is impossible to install several conventional splits. They are convenient for servicing a multi-room apartment. By purchasing a multi split air conditioner, you will not be able to save on the purchase. Since the outdoor unit MCC contains expensive and very sophisticated equipment. We also add the cost of highways and installation. And we get that the costs are more.
Types of multisplit air conditioners
- fixed;
- typesetting.
The fixed system leaves the factory in the final configuration. It already contains one outdoor and several indoor modules. The number of connection ports on the outdoor unit matches the number of internal ones. Their type and capacity is determined by the manufacturer. The outdoor multi-split air conditioner module can be equipped with 1 or 2 compressors. If compressor is 2, then indoor modules can be switched on in different modes. Since the circuits of the compressors are different. This quality is unique to fixed-type multisplits.
With a single compressor, all indoor units will operate in the same mode. Each indoor unit of a multi system air conditioner is given its own remote controller, which is suitable for all units.
Typesetting systems are completed from one outdoor unit and many (up to 16) indoor units. They are connected by a system of splitters. Up to 3 compressors are possible in one outdoor unit, but there is only one refrigeration circuit. Therefore, all indoor modules simultaneously "cool", "warm" or "dry". Any number of indoor units can be connected to the outdoor unit, but the amount of capacity must correspond to the capacity of the outdoor unit.
The types of indoor modules are selected at the customer's request: cassette, wall, duct, floor-to-ceiling or columnar in any combination. Each comes with its own remote control.
Advantages and disadvantages of multisplits
The main plus of air conditioners with multi-split systems is the only outdoor module.
Minuses:
- all indoor modules work in the same mode;
- expensive system;
- if the outdoor unit breaks down, all rooms remain without air conditioning;
- a very accurate calculation of the system is required, which only a professional designer can cope with, flaws in the selection of flow splitters will lead to an uneven supply of refrigerant to different indoor units;
- competent installation is necessary.
