specifically with our customers in mind.
How Air Conditioning Works
Mitsubishi Electric’s air conditioning systems use heat pump
technology to provide heating, cooling and hot water where
required. Our heat pumps require only a small amount of
electricity to harvest, upgrade and move heat from one
location to another.
To achieve this a vapour compression cycle is used, which
has the ability to move heat from one space to another. Low
temperature heat from the environment can be increased to
usable temperatures inside the building in the winter, or
waste heat from a building can be moved outside in the summer,
or even recovered in to hot water.
The efficiency of a heat pump is known as the Coefficient of
Performance or CoP (or Energy Efficiency Ratio (EER) in
cooling mode). This is a ratio of the heat delivered to power
The operation of a heat pump is similar to a refrigerator.
This process is known as the vapour compression cycle and the
following is a more detailed explanation and example of the
system delivering heat into a building. Cooling is the same,
but the heat is taken from the inside and rejected to the
