- Advanced technology 31
- The functionality benefits explained before highly efficiency system wide capacity range and expanded working range are direct consequence of the advanced technology applied on all the system components 31
- Then the main features on different components of the system will be detailed 31
- High pressure shell it acts as an oil separator reducing the amount of oil circulating in the cooling system giving better heat exchanger efficiency motor heat is not added to the suction gas before compression which reduces the discharge gas temperature this is particularly important at low suction temperatures the discharge gas cools the motor sufficiently refrigerant cannot enter the shell during the off cycle causing oil dilution and oil foaming at start up new system of regulating pressure increasing the compressor s efficiency and reliability in part load mode this sys tem ensures the work pressure of the compressor is always at optimum level regardless of the charge so that the ratio between the discharge pressure pd and the suction pressure ps is optimum as in the following graphic 35
- Reduced power consumption highly efficient dc scroll compressor use of neodymium magnets in the compressor motor rotor new inverter control self demand control auto control of power consumption which can be regulated from 100 70 and 50 of nominal value avoids excess energy consumption by regulating the frequency 35
- Wave mode regulation of demand through wave control the demand is regulated by controlling the wave 35
- 000 4 000 6 000 37
- Characteristics at low speed which affect the annual running cost have been significantly improved 37
- Dc compressor with neodynium magnet 37
- In case of existing machines with constant speed repeated turning on and off wastes energy 37
- In the case of utopia series quickly reaches the temperature set at high power then maintains stable energy saving operation in the case of other constant speed machines slowly reaches the set temperature then turns on and off repeatedly to maintain the temperature operating uneconomically and wasting energy 37
- Low noise inverter control the inverter controls compressor speeds from 30 hz to 115 hz quickly reaching the set temperature and maintaining a stable energy saving operation thus reducing the noise since the compressor is not running conti nuously 37
- Power consumption in heating mode 37
- Setting temperature in heating mode 37
- The use of a dc compressor with neodynium magnets in the rotor improves the performance at around the 30 40 hz range where the operation time of the inverter compressor is longest additionally to suppress electromagnetic noise interference and achieve low noise the rotor has been divided into two parts and the electric pole displaced 37
- Acoustically insulated compressor the scroll compressor is insulated by means of a acoustic cover providing mini mum noise levels 38
- Optimized rotor shape the scroll compressor allows reduced noise and vibration levels due to the compression points are evenly distributed along the compression stroke the reduced number of components used use of a high pressure insulation shell 38

- Before selecting the outdoor unit it s necessary to take into account some important possibilities that offers the set free system 50
- Capacity kw 50
- Considering the layout of the building the possible position of the indoor units and the air flow distribution select the unit features that provide the greatest efficiency and comfort decide a position for the outdoor unit that facilitates service and maintenance tasks as well as easy refrigerant pipe installation 50
- First of all it will be considered the possibility of the reduced total outdoor unit capacity as a result of the wide range of operation capacity control available in the set free systems which enable at the outdoor unit to choose a maximum total combination horsepower of 130 and a minimum total combination horsepower of 50 by combination of the indoor units when compared with the nominal outdoor unit capacity the possibilities of fs v n y 2e series are shown in the following table 50
