Lets go green life s good when it s green 2.
All other companies use vrf for their similar hvac systems.
This refrigerant is conditioned by a single or multiple condensing units which may be outdoors or indoors water or air cooled and is circulated within the.
The outdoor unit fitted outside the room houses components like the compressor condenser and expansion valve.
Refrigerant only where refrigerant is the only coolant material in the system in contrary to the chilled water systems where refrigerant is used for cooling heating the water that is circulated throughout the whole system.
The innovative vrv system provides heating and cooling ensuring comfort all year in commercial settings.
First launched in japan in 1982 the daikin vrv system has been embraced by the world markets for over three decades.
Like ductless minisplits vrfs use refrigerant as the cooling and heating medium.
Split air conditioning 5 it consists of one indoor unit along with an outdoor unit constitute a single split ac.
When daikin launched the vrv air conditioning system in 1982 it introduced the world s first use of variable refrigerant flow control.
The system now offers an enhanced line up to meet an ever widening variety of needs while improving energy savings comfort and ease of installation.
2 split air conditioning system the split air conditioner comprises of two parts.
2 power consumption is around 30 claimed less then as compare to split system.
It s a very sophisticated technological air conditioning system based on several principles.
1 single idu with single odu.
The indoor unit comprises the evaporator or cooling coil and the cooling fan.
Vrf vrv split ac 1 single odu with multiple odu.
This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones.
