ducted split units

Variable refrigerant flow technology has been available since 1982 when Daikin, a company from Japan which specializes in air conditioning invented it and the first to launch it commercially. Daikin named this technology VRV or variable refrigerant volume and has the copyright of this name. This name is still being used today.

Since then, other companies such as Mitsubishi, Panasonic, LG, Samsung, Toshiba, Trane, Lennox and Midea have developed their own versions of this technology and called them VRF or Variable refrigerant flow.

تتوفر تقنية تدفق المبردات المتغيرة منذ عام 1982 عندما اخترعت شركة Daikin ، وهي شركة من اليابان متخصصة في تكييف الهواء ، وأول شركة تطلقها تجاريًا. أطلق Daikin على هذه التقنية VRV أو حجم المبرد المتغير ولديه حقوق الطبع والنشر لهذا الاسم. هذا الاسم لا يزال قيد الاستخدام اليوم.

ومنذ ذلك الحين ، طورت شركات أخرى مثل ميتسوبيشي ، وباناسونيك ، وإل جي ، وسامسونج ، وتوشيبا ، وترين ، ولينوكس ، وميديا ​​إصداراتها الخاصة من هذه التكنولوجيا ، وأطلقوا عليها اسم VRF أو تدفق غاز متغير.

Package air conditioner is a bigger version of the window air conditioner. However, units, it has a higher cooling or heating capacity and is usually able to cool an entire house or a commercial building. The nominal capacities ranges from 3 tonne to 15 tonne.

The conditioned air are transferred to the space to be conditioned through ducting which is usually hidden in the ceiling and wall of the building. The unit is placed outside the house, a special room in a building or even on top of a roof. This unit is factory assembled and skilled technicians are needed to install this type of unit.

Protection devices such as High/Low pressure switch, overload relays for all motors, water flow and air flow switches are included in the units. The compressor have winding protection thermostat built into the winding to disconnect the circuit in the event of overheating.

There is an interlocking circuit with the evaporator fan motor starter to ensure that the compressor can only start if the fan motor is running


This self contained unit is assembled in a casing where all the air conditioning componenets are housed. They include:

  • Compressor usually hermetic or semi-hermetic type for operation on 380/400 Volts 3 Phase is used.
  • Water-cooled or Air-cooled condenser.
  • Electrical Panel.
  • Thermostatic Expansion Valve.
  • Air Filter.
  • Front Panel & Return Air Grill.
  • Evaporator Coil.
  • Evaporator Fan And Housing.
  • Heating and Humidifying Components may be included in the unit. Dehumidification is needed for cooling mode during summer and Humidification for heating mode during winter.
