Summer brings not only fine weather, but also midday heat. Fortunately, modern technology is ready to save a person from torment.
Do you have a hard time too? Then take this article for a few minutes, since today we will focus on the cassette type of semi-industrial air conditioners.
Fundamental concepts
Cassette air conditioning is a type of split system, which differs from its competitors by a divided air conditioning system. The design of such devices implies external and internal units with specific capabilities.
This approach saves living space, money allocated for installation work, but most importantly - it is characterized by a low noise background (the capacitor is brought out).
The system is designed to integrate the indoor unit into a suspended ceiling. The dimensions of the component allow - 0.5 x 0.5 meters at a height of 20-35 cm.
Design features of the outdoor unit
Appearance and "internal space" is no different from analogues. Having screwed the protective “box”, we see:
- refrigeration circuit (condenser, heat exchanger and tube) - is responsible for transporting the air mixture into the room;
- condenser fan - provides air circulation through the heat exchanger;
- protective shell - prevents damage to peripheral components, precipitation is also not terrible;
- control device - coordinates the work of the split system.
The refrigeration circuits of the indoor and outdoor units are combined with freon communications. Thus, a closed loop of the ventilated system is created.
Design features of the indoor unit
The dimensions of the component obligated manufacturers to compose components otherwise, the list of which is presented below:
- refrigeration circuit (heat exchanger and evaporator) - is responsible for the removal of warm air outside;
- centrifugal fan - organizes air circulation through a heat exchanger and filter;
- filter plant - is engaged in cleaning the incoming mixture;
- air distribution system - adjusts the direction of flow of chilled air.
The principle of operation of the cassette air conditioner
The main idea of the designers is to ensure that the air mixture is brought out and quickly replaced with a cooled analogue. A couple of physically separated refrigeration circuits cope with the task.
The evaporator (indoor unit) cools the incoming air indoors.
The condenser (external component) is engaged in heat removal of the “objectionable” mixture according to the climatic parameter. The exchange of heat provides the refrigerant.
The location of the evaporator was chosen successfully - cold air streams disperse through the room 360 degrees.
Features of installation work, practical use
Installing a cassette air conditioner It is conditionally divided into the following stages:
- Installation of outdoor and indoor units.
- Laying air ducts and establishing power supply to the device.
- Installation of control panel (in case of industrial use).
- Test run and “fit”.
The outside does not cause installation problems, while the inside requires skill. The best solution is to combine the ceiling tension with the installation of an air conditioner.
Air conditioning of large rooms requires a stationary shield of appropriate dimensions (here you can not do with a portable remote control).
The main purpose of the semi-industrial class device is to maintain the temperature in rooms with large quadrature. It is optimal to use the cassette variety in:
- shopping centers;
- catering;
- gallery and museum complexes;
- industrial enterprises (workshops).
More advanced systems can ionize and humidify indoor air.
Advantages and disadvantages of cassette conditioning
Like any creation of human hands, air conditioning has a list of strengths and weaknesses.
End users like:
- lack of noise from a functioning device;
- inflow of fresh air and its circulation in all directions;
- high productivity and large coverage area;
- harmonious implementation in the design of domestic premises, the absence of a bulky design in sight.
Buyer is concerned:
- the need for installation before repair work in the room;
- mandatory presence of a tension structure, from 150 to 300 mm of inter-ceiling space;
- increased cost of semi-industrial split systems.
Cassette air conditioner covers a large square of the room at low cost for installation and operation.
Features of servicing a cassette split system
An air conditioning device requires periodic replacement of air filters. Design features (decorative panel) provides direct access to the component - disassembly of the suspended ceiling is not necessary!
It is recommended to wash the plastic panel once a month, since caustic fumes settle with enviable consistency on a “snow-white” surface.
It is better to entrust the installation work to professionals, since errors in self-assembly will result in irreparable damage to the equipment.
Popular manufacturers and decent models
The recognized gurus in the production of cassette air conditioners are Daikin, Mitsubishi and General Fujitsu:
- Fujitsu's AUYG18LVLB / AOYG18LALL features improved turbofan blades, small footprints and low noise levels. Designed not only for residential buildings, but also for the office. A price tag is visible on a smooth surface (about 100 thousand rubles).
- Mitsubishi Heavy FDTC25VF is an inverter device with an integrated drain pump that raises condensate above the ceiling. The portable remote control is used to control a complex air conditioning system, there is an automatic restart function. The final cost is a little more than 90 thousand rubles.
- Daikin FCQN125 / RQ125 is a semi-industrial air conditioner of cassette type, which features a stylish design of a decorative panel. In addition to appearance, the model has excellent acoustic characteristics, 3 auto-swing schemes are provided. The cost of an air conditioner ranges from 110 thousand rubles.
Among the budget manufacturers are popular: General Climate, Ballu and Midea.
Cassette air conditioning refers to the semi-industrial type of devices, characterized by an unusual layout and arrangement of functional blocks. The principle of operation and installation steps are identical to brothers in air conditioning in the room.
