Split systems Oasis: model range and subtleties of choice

The split system Oasis is a line of equipment models that maintain a comfortable indoor climate. They are produced by the Forte Klima GmbH trademark and are characterized by high quality, increased efficiency, and good technical properties. The first line of models of this brand appeared on the German market 6 years ago. And 4 years ago, the product began to appear in European countries.

Forte Klima is engaged in the production of household, semi-industrial and industrial devices of this type:

• conventional equipment;
• inverter devices;
• channel equipment Oasis;
• semi-industrial type cassette devices;
• floor and ceiling products.

This type of device is most common among consumers, because it is for it that demand increases from year to year. The air conditioning function, operation in the "warm" or "ventilation" positions of Oasis split systems usually occurs with the operation of two units, one of which is outdoor and the other is indoor. The outdoor one contains a compressor with high performance characteristics.

Since Oasis equipment belongs to the low cost price category, it is not multifunctional. But the product copes very well with the main functions such as heating, cooling and airing. The Oasis split system includes additional functions:

• turbo mode to make the unit work more efficiently;
• night sleep mode, which reduces performance and noise at night;
• automatic function of detecting equipment malfunctions;
• timer that turns the system on and off according to the set parameters.

This is the best-selling Oasis line of equipment, operating on the reliable refrigerant R410A and doing very well with the main goal of creating a comfortable indoor climate ranging from 25 m² to 90 m².

Such equipment, unlike conventional split systems, makes it possible to regulate the speed of the compressor electric motor by converting alternating voltage to direct voltage.

If you need to cool or, conversely, heat rooms with a large area, for example, shops or restaurants, where there will be little use from wall devices, then floor systems are used.

They have a complex composition and working rules.

1. An outdoor unit that is directly outside the building. Through this block, air enters the blowing system, from where it is fed into the building through an electrically driven air valve.
2. Now the filter of the device cleans the air that comes in from the street. If necessary, the heater heats it up.
3. Bypassing the duct fan equipped with a silencer, the air flow enters the duct of the intake group.
4. Subsequently, the air goes to the air conditioner unit, where it acquires the desired temperature.
5. The air reaches the room by means of an air duct with a grill. Grilles are usually made of metal and can be floor or ceiling.

To regulate such systems, a control panel is used, which makes it possible to:

• turning on the self-diagnosis system;
• setting the activity of the device for heat, dehumidification, cooling, ventilation of the room;
• setting a certain temperature on the equipment.

Regardless of the technical equipment, if you do not follow the rules of operation and maintenance, then this equipment may become faulty. This can happen due to:

• freon leaks;
• short circuit in the compressor;
• breakdowns of the control board;
• freezing of the heat exchanger;
• clogging of the drainage system.

If any of these reasons exist, the self-diagnosis function will alert you of a problem with a code consisting of numbers and letters on the screen.

To the positive characteristics of this equipment the following points can be attributed.

• The equipment has a reasonable cost, available to everyone. During its activity, it does not allow strong noise, it cools the room well.
• If the equipment was installed by a service center, then the warranty period of service is 3 years.
• It cleans the air well.
• In the event of a voltage failure in the electrical network, it retains its settings.
• The outdoor unit does not vibrate even under heavy load.
• At a low cost, the quality of products is high.
• It does not have a strong unpleasant odor of plastic, as is often the case with Chinese-made products.
• Monitoring the health of functioning elements.
• Easy installation and use.

The disadvantages of this device include such characteristics.

• Easy to design and assemble in China.
• Too noisy outdoor unit. The fault here is the Chinese compressor.
• Low work intensity.
• If the board malfunctions, it will take several months to recover.
• There is no LED indicator on the indoor unit of the device.
• There is no backlight on the control device.
• Spare parts should only be purchased from a service center.

When choosing a quality split system you must adhere to the following recommendations.

• First you need to decide on the type of system. This will make it possible to significantly narrow down the search.
• An important criterion in the selection of a device of this type is the cost. The functions of the equipment must correspond to its price; it makes no sense to overpay only for the name of a well-known trade mark.
• Serviced area. It is determined by the number of square meters. If it is necessary to install a multi-split system, then the entire serviced area will be made up of the totality of the areas of all premises.
• Average and maximum intensity of the device. Medium is the one set by the manufacturer. This power will be reduced under the influence of ambient conditions. Therefore, it is necessary to clarify the real and maximum power.
• Ionization filters. They play an important role. They prevent germs from entering the device and remove viruses and allergy-causing particles from the air. They have one negative feature, they need to be changed periodically.
• Lack of strong sounds. This parameter can be found in the technical specifications of the device. It is necessary to pay attention that this parameter does not exceed 19 dC.
• Smart sensors. They represent functions that overload the operation of the air conditioner and increase the power of the electrical energy.
• It is better to give preference to inverter systems.They will help not to consume a lot of electricity and will maintain the desired temperature regime.
• Take into account the weight of the split system. Quality equipment will have a lot of mass because the parts must be made of metal, not plastic.
• It is good to choose devices with an iron outer block, because the plastic one changes its shape under the influence of temperature fluctuations.
• The system must be installed by a service specialist, because it is he who will give a guarantee and is responsible for the quality of work.
• The remote control should be comfortable and easy to use.
• Installation is best done in autumn or spring. Because in the summer, the cost of equipment increases due to the increasing demand.

Customer reviews are mixed, there are both positive and negative. There are many more positives. Users liked the following characteristics of the units:

• practically silent;
• good appearance;
• stylish design;
• cools well;
• acceptable cost.

Negative reviews include:

• even at the smallest speed it blows quite strongly;
• beep too loud when changing mode.

The choice of Oasis split systems is quite extensive, so everyone can choose a device to their liking and financial capabilities.
