Today very wide choice of coolers of air is offered to the consumer. In the course of the choice the buyers pay attention first of all to technical characteristics of such equipment. But it is necessary to learn about the principle of operation of the conditioner, actually, in detail.
The first invertor convector has been released thirty years ago. Since then it has a little changed, and producers use the same manufacturing techniques of the cooling systems today. It is difficult to overestimate role of the invertor conditioner around the world. Today the specialized outlets offer wide choice of such equipment, and here upon purchase of this device not to do without certain knowledge. When choosing the conditioner the buyer faces first of all that convectors have absolutely different principles of work. There are essential distinctions of the simple conditioner and invertor.
Distinctive characteristics of the invertor conditioner
What means the invertor conditioner? It means that such conditioner is completed with inverter – the device capable to smoothly change device power. After the first inclusion the system will cool the room up to the required temperature, but right after it will not be disconnected, and will continue work, but from lowered for 25-75% (sometimes for 5-90%) power. It is reached due to use in inverter unit design. Work is continued at low powers that allows to compensate heat fluxes which come to the room. Thus, the invertor conditioner can function 24 hours a day. And because such conditioner works almost constantly, without sharp inclusions and shutdowns, there is less load of the power supply network and, respectively, on the device. But it concerns only expensive models which power changes ranging from 5 up to 90%, only they are almost capable not to be disconnected.
The majority budgetary invertor Split systems nevertheless are completely disconnected, but much less than not invertor conditioners. The sensitivity of system on differences of tension provides obligatory use of the stabilizer in the power supply network. Energy consumption of the invertor conditioner is much lower, than at the conditioner not invertor. Noise level of the invertor conditioner minimum. The lack of drafts also gives it big advantage in front of the simple conditioner. The risk of drafts and overcooling and, in the investigation of it, probabilities of catarrhal diseases decreases. Such type of the device more comfortable in operation. If choice is made and has fallen on the invertor conditioner, then it is necessary to buy the device with precise adjustment. Such model costs much, but its purchase is justified. If there is no opportunity to buy the invertor conditioner with precise adjustment, then it is more appropriate to buy the conditioner simple. The fact is that if the adjustment range of the invertor conditioner small, the buyer as a result will not gain the expected effect. It should be noted that upon purchase it is necessary to get acquainted with technical characteristics of model. If they are low, then it is besides more reasonable to buy the simple device.
Leaders in this area by right have recognized conditioners of the Mitsubischi Electrik and Daikin companies. These producers release the most comfortable invertor conditioners. Their cost is high. But there is also alternative in the price range lower. The Japanese firm Sahyo also releases invertor conditioners with comfortable operating conditions. And they are budgetary, than top devices of the known Mitsubischi Electrik and Daikin brands. The Sahyo brand Mini Shiki Sai series quite deserves attention as meets requirements to invertor conditioners and is worthy alternative to expensive cooling devices. Today the Korean companies offer the quite good conditioners with the invertor drive which are not of a lower quality the Japanese brands. In comparison with the Japanese analogs the Korean devices it is not worse, but is slightly cheaper. The Chinese producers release inexpensive invertor conditioners, but they are capable to reduce own power only ranging from 35 up to 70% that it is much worse, than at units of production of the Japanese and Korean brands.
Features of repair of the invertor conditioner
When choosing the cooler it is necessary to pay special attention to its maintainability. At the invertor conditioner repair will cost much above, than at simple. The compressor and system at the conditioner invertor and at simple – identical, and the cost of their repair especially does not differ. But also they break extremely seldom. Expensive repair will be connected with electronics. To repair the invertor conditioner it will not be cheap if electronics departs". In the device power modules are used, and they are very sensitive and often are exposed to differences of mains voltage. If there is breakage in the field of payment, then repair will manage in the amount of the cost of the new not invertor conditioner. One more unpleasant moment – necessary power modules more often does not appear and therefore repair of the cooling device can be not possible.
Profitability and life cycle of the invertor conditioner
Producers of invertor conditioners state that their devices are much more economic, than simple conditioners (for 30-40%). And in the conditions of continuous increase in the cost of the electric power it can become turning point upon purchase. But official data do not confirm that invertor conditioners are more economic, than simple. Moreover, the high cost of invertor conditioners increases their payback period up to 5 years unlike inexpensive not invertor conditioners. Is considered upon purchase of the invertor conditioner and its life cycle. Producers of invertor cooling systems point that power during their work low, and life cycle of such devices makes from 8 to 15 years. But it is relevant only under ideal conditions of operation when there are no jumps in the power supply network. And as it occurs not seldom, invertor conditioners also break quite often. Therefore the life cycle declared by the manufacturer is very doubtful argument. And it is not defining upon purchase of the simple or invertor conditioner.
How to make right choice upon purchase of the cooling device
The choice of the conditioner has to be thought well over. Attentive studying technical characteristics of the device and conditions in which the conditioner will be operated has to be considered as obligatory. In case this office room, then acceptable is to buy the normal conditioner. If it is the small house or the apartment, the invertor conditioner will be very opportunely. Invertor conditioners are capable to support the set temperature parameters precisely. At the same time temperature variation indoors makes only 1-3 degrees that provides the maximum comfort of people. The normal system in hot weather demands control for maintenance of 18-20 degrees. On sale generally classical models of simple conditioners are provided today. They inexpensive at cost are suitable for cooling of technical rooms, archives, warehouses more. At constant opening of doors the invertor conditioner is not capable to react unlike the simple device. For small rooms, kitchens and bedrooms it is better to use invertor conditioners with precise adjustment. Their cost is 40% higher, than the cost of the simple device. But the lack of drafts and noiselessness do its purchase justified.
