What is the difference between the inverter and non-inverter device?
The difference between the inverter and non-inverter devices is in the control of speed of compressor. Specifically, the old devices that have not had control of the compressor speed are being turn off at the moment when the sensor on air intake of indoor unit noted that the temperature is the same as set on the remote control device, while the inverter devices do not turn off but remain at the 20% of speed of compressor. Many would think that this is not an advantage in compared to non-inverter device, but electric motors that drive the compressor starts with taking 8-10 times stronger current than the rated which causes increased power consumption.
Can I clean my air conditioner before I turn it on for the first time in the summer?
No, you can only maintain the filters on the inlet of the indoor unit. It is easy access them and even easier is to clean them. Each indoor unit has a slots on the sides that can be used to open the cover of indoor unit and for access the filter. It is very easy to clean filter with warm water. This way you can reduce the number of regular services, during which the indoor unit must be disassembled to gain access to interior of unit and the fan which is the most dirty part of unit if not maintained regularly.
The temperature of comfort depending on the regime.
When we talk about heating, then the concept of sensible temperature does not vary much and the temperature of the area in which a person resides without any physical effort has to be 20˚C + / - 1˚C. For the purpose of cooling the sensible temperature of treated area should not vary from the external temerature and differences should not exceed 5-6˚C above the outside temperature.
Montage of air conditioners.
Before montage of air conditioners you should pay attention to several things. Given that mounting an air conditioner is one of our activities, we want to warn you to some basic rules that should be respected.
Position of the indoor unit must be such that it is not blowing in part of the space in which people are mostly staying.
Neither indoor nor outdoor unit should be in a confined space, which would interfere on the blowing. For indoor unit is not good that is in a narrow corridor, opposite the second wall or above some sort of cabinet or shelves. The outdoor unit must be outside, not in the attic, garage or similar.
The distance between the two units should be as small as possible, because of potential power losses and overloading of equipment. For inverter models it should not exceed ten meters. For more expensive models it is allowed up to twenty meters.
The condensate produced by the indoor unit should be think about, when it cools, or the outdoor unit when it is heated. Given that the air conditioners usually do not have built in pump for water, from the bottom of the air conditioner must be pulled pipes that get rid of condensate. The pipe must have a constant downfall, with no part of which would constitute a siphon in which water would be retained.
For regular customer is very difficult to choose an air conditioner that it will respond to customer needs. Therefore, we strive to ease the selection of air conditioners, and briefly inform you about the air conditioners.You can also use the calculator for air-conditioners, which we have prepared for you to make easier to find a model that suits you best.
1. Low Class
In this group we can classify the air-conditioners of various exotic and unfamiliar names. They can be cheap to buy in various shopping malls or retailers which saw opportunity for selling air-conditioners and have imported several containers to sell out. After that it will be very difficult and practicly impossible to find spare parts and the authorized servis. This air conditioners will work solid in cooling mode but poorly in heating mode and typically do not last long. They are very noisy and consume more electrical power (small EER and COP) then air-conditioners from the upper classes. For any biger failures (the compressor or electronics) they are not worth repairing. This air-conditioners can be recommended only for undemanding consumers to whom are only important any kind of cooling, but heating have been solved another way. Cost from 1 000.00 to 2 500.00 kn.
2. Middle Class
In this group we can classify air conditioners better known brands that have been with us for some time and for them we know how they behave after a few years of exploitation. Behind them is usually a serious importer which provides spare parts which are not overly expensive. These are the air-conditioners for customers with medium-sized financial power. These air-conditioners cools well, and heat pretty well down to 0°C. They are not very noisy. In Dalmatia, with an additional heating (for a couple of cold days) can cover the entire winter for heating. Cost from 2 500.00 to 4 000.00 kn.
3. High class
In this group are only Japanese air-conditioners (no matter in what country were produced). They work great for many years. During this period it will return to you the difference in investment between this class and middle or low class due to large differences between embedded and obtained energy (high EER and COP). They are extremely quiet and with no problems can cover need for heating in whole year, especially inverters which are technology for themselves. By purchasing these air conditioners can save electricity, preserve the environment (using eco gas R410A and R407c) and have minimal malfunctions. Cost from 5 000.00 to 10 000.00 kn.
Which air conditioner to buy, depending on the need and usage of space?
Although we made available inspection service to all our customers, by this article we want to present you all the factors that influence on the selection of air conditioner, and why is wise to let the choice of air conditioning to experts. Priority in selecting an appropriate air conditioner for your space is ratio of air conditioner power and efficiency. What is that ratio better - or what device is better selected, your room will be better cooled or heated at a minimal cost. When choosing an air conditioners that will be used for heating it is necessary to take a stronger air conditioner (about 30%) than we need in cooling. Less quality air conditioners, although you properly take into account all the given criteria, can not warm up space when the outdoor temperature is around or below zero (at same time working permanently because they can not reach given temperature, thereby consuming a greater amount of electric power in return for not offering no effect). Therefore, when choosing an air conditioners to be used in heating it is necessary to take higher quality air conditioning inverter, that work to - 15°C outside temperature while consuming up to 40% less electricity than standard equipment. It is necessary to pay attention to consumption of air conditioners, that is classification according to energy efficiency - EER and COP.
The first criteria: purpose and form of room
It's not negligible if you are setting the air conditioning system in house, apartment, coffee shop or a large exhibition hall. The first thing to consider is the shape of the object - for example in a flat with many rooms it will not be possible to climate entire apartment with only one unit, but only one or possibly two rooms while for a smaller studio that does not have too many walls one device will be more than sufficient.
Very essential are the glass surfaces of windows and walls of space - lower spaces with less windows can be climate by a weaker air conditioners than those with high walls and many windows (like showrooms).
When frequency of opening door is greater, we will need more powerful device to reduce the time of re-cooling the space after closing the door.
Every person in the room radiates a certain amount of warmth (body, breath). Commercial areas with many employees will require with more powerful devices.
Finally, objects that radiate heat (lamps, cabinets, computers, machines, TVs ...) must be taken into consideration and are located in a room that is intended to equip with air conditioner.
The second criteria: size of room
In order to simplify the whole story, instead of explaining the process of calculating the appropriate air conditioner, depending on the quadrature and height (the internal volume) of space, we enclose the following table for you to get a feel for the necessary power of air conditioner. What air-conditioner you need? These are only guiding values. The correct calculation should include all the factors that influence the choice of air conditioner, and this is best to leave professionals.
IMPORTANT: For a mono split air conditioner is usually taken only one value for the room in which is the unit.
The third criteria: climatic zones
If you live in the inland of Croatia, where winter temperatures are much lower than at costal area you will for heating need an air conditioning which can run at lower outdoor temperatures (inverter or quality classic air-conditioning). For cooling there should be no problem. If you live by the sea, humidity is greater than on the mainland. In areas near large bodies of water will be necessary to take into account the average amount of water vapor in the air during the year. For example, mobile devices that have a condensate container volume of about 5 liters are not the best solution for coastal areas, and they will have to be emptied oftenly.
Air conditioners with split system
Split in English means-separated, and separated are internal (vaporizing) and outdoor (condensing) unit.
The indoor unit is placed within the area that we want to cool or heat, and the outdoor unit outside of the building because essential element in its work is communications with the outside air.
Separated units are connected with copper pipes with thermal insulation, electric cables and communicational electric cables.
It is recommended that the total distance between the units does not exceed 10m, however, allowed space between them is determined by the manufacturer, which in some cases can be 25m.
Air conditioners with multisplit system
Multi - means not one but several - indoor units - two, three, four, ... or more, as needed. The possibilities are almost limitless and all this with only one outdoor unit.
Outdoor (condenser) unit can contain one or more compressors, depending on the type and strength of the device.
Characteristics of modern air conditioner
Modern air conditioning must meet technical, health and environmental criteria, and we will mention some of them:
- extremely quiet operation
- low power consumption
- built in electrostatic microfilter dust, pollen and bacteria from the air
- filter with activated carbon to remove unpleasant smell
- use of ecological Freon (non-toxic and non-flammable)
For better comfort and ease of use:
- wireless IR remote control with LCD display
- many programming options
- easy selection modes: cooling, heating, dehumidification
Almost every air conditioner has an automatically setting of lamelaes. The direction of air flow can be adjusted in several different ways: uniformly moving lamellas up and down or in the AUTO mode automatically occupy the ideal position.
Large air conditioning systems
For large air-conditioning systems we must have planned approach, and each system can have its own specifics. Therefore, for large systems we suggest elaboration project that specifies in details the equipment and construction costs for air conditioning systems. In large systems can be used specialized multi-modular systems combining with different types of indoor units.
