Multi Split Air-Conditioner With VRF Technology Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12813
Jlab Export is a leading Multi Split Air-Conditioner With VRF Technology Manufacturer,and suppliers in India
A VRF (variable refrigerant flow) system feeds refrigerant from one outdoor unit to several indoor units and varies how much each one receives. This training system has three indoor units, a capacity of 100,000 BTU and runs on R-410A at 220-240 V, 50 Hz. Pressure gauges on all three evaporators, plus a gauge and sight glass after the condenser, let students follow the refrigerant round the circuit.

VRF Practicals for Students and Teachers
With all three indoor units running, students note the pressure on each evaporator gauge. They then switch the units off one at a time. Each time, they watch how the gauge readings and the sight glass after the condenser change as the system adjusts the flow. A clear sight glass shows a full column of liquid, while steady bubbles point to a short charge or a restriction.
For a service exercise, students connect the Manifold Gauges for Air Conditioning and evacuate the pipework with the Fast Vacuum Pumps. They then weigh in R-410A Refrigerant on the Wireless Refrigerant Charging Scale. Teachers can use the wireless remotes to show how each indoor unit is given an address, then read error and protection codes on the centralised controller. Setting it beside the Multi-Head Mini Split Heat Pump Training Unit shows how a VRF system differs from a two-zone multi-split.
Frequently Asked Questions
What does VRF mean?
VRF stands for variable refrigerant flow. One outdoor unit supplies refrigerant to several indoor units, and the system changes the amount each indoor unit gets to suit its load. This set has three indoor units on one outdoor unit.
How many indoor units can one system handle?
Up to 100 indoor units can be connected in one system, and one centralised controller can control up to 100 indoor units. The controller connects to the outdoor units only and can run a single unit or all units together.
How far apart can the units be installed?
Total pipe length can reach 1000 m, with the longest pipe given as 200/240 m. The height difference must stay under 90 m with the outdoor unit above, under 110 m with it below, and within 30 m between indoor units.
What can be set from the wireless remote?
Each remote sets the temperature, operation mode, fan speed and timer for its indoor unit. It can also read and set the indoor unit address, which the system uses to tell one indoor unit from another.
How is VRF different from an ordinary multi-split?
A basic multi-split often runs a separate pipe pair from the outdoor unit to each indoor unit. A VRF system uses a shared pipe network with distributors and controls the flow to each indoor unit, so it suits buildings with many rooms.
