With VRF (Variable Refrigerant Flow) technology, it
compressor according to the internal demand (thermal load), providing a
reduction in energy consumption in partial loads.
The refrigerant flow is modulated by the frequency variation in the engine of the
compressor. This technology is called Inverter.
The evaporator plate has basically the same components as the
evaporators Hi Wall with fixed speed, however the logic is different. For this reason it is not possible to match a common Hi Wall evaporator with an inverter condenser.
The main differences are in the condenser:
- The boards transform an AC input into a variable DC. In units of 9 and 12
KBtu / h there are 2 plates to perform this task, the other capacities use a plate in the condenser;
- An Inverter compressor (varies its rotation) that works with direct current;
- A reactor that filters the voltage;
- Three temperature sensors: external environment, serpentine and discharge;
