selection of the equipment, without doubts, will prevent future problems.
For that reason, the following aspects should be taken into account:
Must be chosen taken into consideration some factors
such as future space usage (residential, social, commercial, industrial,
etc.), number of people, quantity and location of doors and windows,
winds and sun direction, construction materials, insulation, external
temperatures, electrical appliances, external and infiltered air,
all of it, after performing a detailed analysis of thermal loads.
An oversized equipment will air-condition the space but since it operates
at short cycles, might not be capable of removing all the humidity
bringing out a cold but sticky space caused by humidity. On the other
hand, a sub sized equipment will create a space in which a comfortable
temperature will not be reachable even though the system is operating
Select the right model for the space to be air-conditioned
bearing in mind the wide variety of existing models both split and
packaged systems with axial or centrifugal fans in the condensing
unit and standard, duct, fan coil and ductless evaporating units for
direct expansion or cooling water, all of them intended to satisfy
different needs and uses.
It is very important to locate the condenser in a place
where fresh air can be taken freely from the environment and its discharge
has to be without any restriction. Likewise, the evaporator requires
of enough space to take the returning air and to allow an easy access
to its filters. In both cases, it must be foreseen not to obstruct
the detachable panels for the purpose of checking out the equipment
at the event of any inconvenient, and also the availability of electrical
and water taps and nearby drainage for its maintenance.
Special operational conditions such as irregular voltage
supply and excess of dust or salinity in the environment must not
