As
we’ve just seen, this type of A/C system is made up of two parts;
the internal unit and the external unit. These two units are connected
to each other by two lines of refrigeration pipework and by an electrical
connection. As
with the window A/C unit, the split system removes heat from the
air-conditioned room by means of three circuits: one
refrigeration circuit and two air circuits.
The
split system is the commonest type of air conditioning in use today.
We will use it for the major part of our studies from now on. We
will learn about its operation, the technology it uses, its installation,
commissioning, maintenance and simple repairs.
Before
looking in detail at its operation, we’ll try and become better
acquainted with its various constituent parts.
