Green duct splits are equipped with two conventional heating methods. Regular gas heating (via coil) in single heating mode or simultaneous gas heating with electric heating through an electric grill installed in the duct split assembly, using both heating modes to reach desired air temperature in winter, typically providing optimal heating in winter for the coldest duct split unit.

Simple duct splits use On/Off rotary compressors. The compressor operates by turning off when room temperature reaches the set temperature, and turning back on when temperature rises.

Inverter duct splits use inverter rotary compressors. The compressor capability allows it to turn on and off proportionally with temperature rise and work automatically with temperature drop, reducing the adjustment time period to 30 percent and maintaining relatively stable temperature. Duct split inverters have high consumption and efficiency (in gas usage) and are updated.

Given the variety of implemented duct designs and their mechanical installations in buildings with low false ceilings, this system installation - for internal duct split mounting doesn't require the building to have ducts, therefore the duct split is recommended to be installed in the ceiling (usually corridors) or wall.

General technical points of duct split, in fact the implementation of duct split measurement is the first and most important element in implementing air conditioning system. Reducing or increasing hall humidity and this in design and performing initial calculations of ducts and air transfer and return paths, general points of duct split in fact building ventilation systems and using other factors will have an important role that increases system performance in supplying or removing it. Types of implemented duct splits in common system are very important. Types of duct splits should be considered for service and waterproofing in compromises of notable duct types.

Considering the system and repairs, duct splits have more complex systems compared to split air conditioners, which has been raised by this company's service unit. Repairs and specialized maintenance of Green duct splits are covered by Aria Sarma warranty, and for out-of-warranty customers and issues with current status and service delivery, you can contact through number 021-91009769 Green after-sales service for repair with installation.

Low initial cost in duct split system is the first and most important reason for using this system. Its lower initial cost (about 30%) compared to other systems like chiller and fan coil. Fresh air supply in duct split system - in this system, the building's required air exchange with oxygen is provided from outside (through duct) in both winter and summer. Use of variable speed or inverter technology in duct split system. Duct splits come in two types - inverter (variable speed electric motor that drives the compressor) and conventional (fixed speed electric motor), where the inverter type allows the duct split to always operate at minimum power and only adjust the compressor drive motor speed as needed to provide desired air conditioning. Given that this device typically uses scroll compressors, this scroll type is cheaper than other compressors and due to having the least number of moving parts, has longer lifespan and less noise and vibration compared to other compressors. Also in other systems like chiller and fan coil, scroll compressor and inverter technology are used. Air filtering in duct split system - ability to filter incoming air using washable filters. Separate charging cost for each unit from the whole building in duct split system - unlike central systems like chiller, the energy consumption cost for cooling and heating each apartment unit is separate and each unit can control its own consumption. Using duct split system instead of multiple splits results in reduced electricity costs, maintenance, and no need for maintenance technician. Air humidity reduction in duct split system - like other refrigeration cycle-based systems (like chiller, fan coil and split), in summer the humidity of passing air is reduced due to water vapor evaporation by cooling coil. Pleasant and powerful heating - like split, it can operate in heating cycle and provide necessary heating using required electricity like cooling cycle, where using gas instead of electricity for heating is more economical, in our country given that energy subsidy for gas is based on economy and energy usage via gas seems completely economical, it is commonly used this way. Thus with cooling air and in fall/winter, the incoming economy path to indoor unit is guided from electric anti valve and economy enters coil, and with device fan rotation, warm air enters spaces and halls.
