Why
The Inverter Air conditioning Range Of Operation Is Important
Inverter air conditioning has revolutionised energy saving for the air conditioning industry since its introduction with the gas of the time R407c, introduced as a interim refrigerant. Air conditioning compressor technology before inverter technology used fixed speed compressors which came off or on at 100% capacity according to the thermostat setting. An inverter air conditioning compressor operates at a variable speed according to the temperature setting, slowing and speeding up the variable speed compressor to keep the temperature at a constant and linear temperature. An inverter air
conditioning unit is perfect for linear temperature control but there
are limitations. If the air conditioning unit is undersized for the area
the inverter compressor will then operate at a high speed level which in
affect works comparably with a fixed speed compressor working at 100%
capacity, thus using more power. The flip side to this is, if the
inverter air conditioning compressor unit is oversized for the area the
unit will not be able to operate within its designated range. Inverter
air conditioning units have a working range for their capacity which
usually starts at a minimum of 1.0kW on small models. Below is a common
operating range of capacities for inverter air conditioning listed by
the main manufactures Mitsubishi and Daikin air conditioning: Typical Inverter Air Conditioning Operating Ranges: 2.5kW / 9000Btu
Inverter air Conditioning units (0.9kW to 2.5kW) 3.5kW / 12000Btu
Inverter air Conditioning units (0.9kW to 3.7kW) 5.0kW / 17000Btu
Inverter air Conditioning units (1.3kW to 5.4kW) 7.0kW / 24000Btu
Inverter air Conditioning units (1.9kW to 8.23kW) Why It Is So Important To Size The Area Up Correctly: The above figures
are relevant when selecting your air conditioning heat pump inverter
unit for the area to be cooled / heated as they give the user a idea of
the minimum heat load. This is usually overlooked as most users go for a
slightly larger capacity for their area to be on the safe side. The
downside to this is the compressor short cycles and never runs to full
capacity. A good example of this is a 3.5kW air conditioning unit that
has been installed in a area that requires ideally a 2.6kW air
conditioning system. The 3.5kw unit has a minimum output of for example
0.9kw which mean that while operating at its minimum operation limit it
will not take long to cool or heat the space and the compressor needs to
switch off before it over cools or over heats the area. This will
affectively mean the air conditioning compressor will switch on and off
when it is designed to run continuously to keep the temperature setting
and it is operating beyond its design capabilities and limiting its life
expectancy. The energy savings that the inverter air conditioning
compressor was designed for is ineffective when installed in a large
area. Key Considerations When Sizing Up Inverter Air Conditioning: Do not oversize the
air conditioning unit as it will end up switching off and on like a old
fixed speed compressor Do not undersize a
inverter air conditioning unit as it will run at full speed like a fixed
speed compressor Look at the
operating range when sizing up your area Try to match the
capacity to the room size to the nearest 500 Watts Contact Us:Sales & Spare Parts: +44 (0)1234
