Air conditioning and heating
The constant demands for improvement of the ways and conditions of life and working environment in housing and business facilities in the form of improvement of climatic conditions led to rapid development of thermal and air technology. Today, artificial climate is a major factor in meeting the demands of a pleasant atmosphere of working and living space. In all heated and air-conditioned spaces, an comfortable work environment should be provided, ideal microclimatic conditions , and rational energy management and environmental conservation. These highly standardized conditioners are devices that have the following characteristics :
– low electricity consumption
– simple installation and low cost jednostavna ugradnja, minimal maintenance
– maximum airflow with low noise level
– remote control, programming, regulation
– acceptable prices
Considering the aforementioned, we distinguish the following features of the air conditioner:
-Single Split systems
-Multi Split systems
-Mobile air condition devices
-VRV Systems
New air conditioning technologies
Every year, innovations of design are noteworthy, especially for indoor unit wall designs, then for electricity consumption, filtration and protection of lamellar heat exchangers. At the moment, the “in” are wall designs of smooth front surfaces, with air slits and with a sliding front panel and display.
SINGLE SPLIT SYSTEMS
They consists of one internal and one external unit with the associated steering wheel (most commonly IR). This is the best-selling type of air conditioner, cooling power range 2.1 to 14 kW, high efficiency (“A / A” energy class), multiple filtration (antibacterial, antivirus and air ionizer), quiet operation of indoor and outdoor units, with heating possibility up to -15 ° C. There are two versions of such systems: fixed speed (constant mode compressor with on / off mode) and inverter (variable compressor operation with operating range of 10-140% nominal power). The inverter type air conditioner has a higher price, consumes less electricity, works more efficiently (stronger) at lower temperatures and is more comfortable indoor.
MULTI SPLIT SYSTEMS
They consists of more (2-6) internal and one outdoor unit with the associated steering wheel (most commonly IR) for each indoor unit. The cooling and heating power range is 4.0-18kW. Inverters are designed to adapt quickly to the requirements of any room where the indoor unit is housed with minimal power consumption. They are the best option when building, renovating, adaptind and so on when the installations are invisible – undercut, and there is only one external unit that is placed so that it is less noticeable (roof, behind the facility, cellar air vent). .
MOBILE AIR CONDITIONING DEVICES
The simplest air conditioning units requiring plugging and hose installation (fi 115mm) for air cooled air outlet, cooled to 2.5 kW, chill up to 20m2 of space, have the most cushioned rating, fall into the «C» energy class. The biggest advantage is the possibility of removal after the summer and the possibility of easy relocation (apartment – cottage etc.).
VRV SYSTEMS
Most recent generation air conditioner systems that consist of more internal (2-64) and one outdoor unit. Cooling and heating power range of 10-60kW Inverter versions with the possibility of efficient heating up to -25 ° C, intended for operation throughout the year in commercial premises such as shopping malls, business buildings, hotels, apartments, etc. with the possibility of individual or Central management of internal units. The biggest advantage is that they are cheaper in operation 20-40% compared to conventional heating over the radiator and gas boiler, cooling is immediately resolved, free walls remain in compliance with today’s interiors standards (no radiators or similar heating elements).
