Mastering Climate Control.
From high-efficiency Split Units to industrial VRF systems and hygienic Air Curtains. Explore the science of cooling with Kohinoor Global.
Understanding Air Conditioning
An air conditioner does more than just blow cold air. It is a complex thermodynamic machine designed to remove heat and moisture from an interior space to improve the comfort of occupants.
We supply the world’s most trusted brands including Daikin, O’General, Blue Star, and Carrier to ensure your environment is perfectly controlled.
The Science of Cooling
The Refrigeration Cycle
How an Air Conditioner actually works: The 4-Step Process
Compression
The compressor squeezes the refrigerant gas, raising its pressure and temperature significantly.
High Pressure GasCondensation
The hot gas flows through the condenser coils, releasing heat outside and turning into liquid.
High Pressure LiquidExpansion
The Expansion Valve restricts flow, causing a sudden pressure drop. This cools the refrigerant.
Low Pressure LiquidEvaporation
The cold refrigerant enters the indoor unit, absorbing heat from your room and turning into gas.
Low Pressure GasOur Air Conditioning Range
Solutions for every scale, from single bedrooms to skyscrapers.
Wall Mounted Split
The most common cooling solution. Silent, efficient, and aesthetic. Ideal for bedrooms, living rooms, and small offices.
Ducted Split System
Hidden above the ceiling, offering a seamless look with air delivered through discreet grilles. Perfect for luxury villas.
Ceiling Cassette
Installs flat into the ceiling grid. Distributes air in 4 directions, making it ideal for large open spaces like showrooms and offices.
VRF / VRV Systems
Variable Refrigerant Flow. Connects one outdoor unit to multiple indoor units with individual control. The gold standard for towers.
Water/Air Cooled Chillers
Massive cooling capacity using chilled water distribution. Used for malls, hospitals, and district cooling projects.
Floor Standing / Tower
Powerful airflow throw. Designed for large halls, mosques, and restaurants where ceiling mounting isn’t possible.
Industrial & Commercial
Air Curtains
An air curtain is a fan-powered device that creates an invisible air barrier over the doorway to separate two different environments efficiently and without limiting access.
How an Air Curtain Works
Air is drawn in via the intake grille (top or front).
Internal centrifugal fans compress the air inside the housing.
Air is forced into the plenum chamber to stabilize pressure.
Air exits via the nozzle as a uniform laminar stream.
Types of Air Curtains
Standard Commercial
Designed for shops, restaurants, and offices with door heights up to 3 meters. These units prevent dust, insects, and heat from entering while keeping cool air inside.
Available in: 90cm, 120cm, 150cm sizesIndustrial Heavy Duty
Built for warehouses and factories with large doors (up to 6 meters). Features high-velocity motors to create a seal strong enough to withstand wind pressure.
High Velocity Centrifugal FansRecessed / False Ceiling
Installed inside the ceiling for a clean, invisible look. Only the discharge grille is visible. Ideal for luxury hotels and high-end retail.
