Thanks to the new Power Inverter system, a large reduction in power consumption is now possible.
This results in one of the highest COP ratings in the industry,
helping to lower overall running costs and providing great savings to customers.
Case study 1. = Power Consumption
Based on our calculations
on the operating conditions
shown below, the new Power
Inverter system can reduce
power
consumption
by up to
70% compared to an old

Heating capacity ranges
The cooling
/
heating capacity when outdoor temperature
is low or high and the maximum operating speed of the
Power Inverter Mr. SLIM have been improved by up to
33% compared to the current model.
Operation is now possible at lower speeds, thus cutting
energy losses produced by the repeated on/off
operation of non-inverter models. Comfort is improved
while power consumption is reduced.
