My system has a 3-year
warranty - Why do I need a maintenance contract?
Air conditioning and building
services systems require regular maintenance to ensure safety and optimum operational
efficiency. Warranties are only applicable if the system or equipment is regularly
maintained by an approved organisation.
To simply explain, relate this to a
car which like air conditioning has many rotating and wearing parts, your warranty will
not be honoured if you don't have regular servicing (maintenance).
Do refrigerants harm the ozone
layer?
Some do and others do not, however
it is a very complex issue and needs more space than we have here. In principle all
refrigerants handled by competent companies and technicians will never be released to the
atmosphere so will not deplete the ozone layer. Because accidents happen, alternative
refrigerants are being developed all the time, but it is important to note that
refrigerants are not a major problem as many other contaminates cause global warming
problems. Primary problems are caused by burning fossil fuels, e.g. petrol diesel, oil
etc.
Can I catch legionella from my air
conditioning?
It is highly unlikely, you are more
likely to catch it from a shower head in a hotel room that has not been used for a long
time. But, legionella can be caught from the aerosol spray of infected cooling towers of
larger, older and poorly maintained air conditioning systems.
I have been told that air
conditioning spreads viruses and bacteria - Does it?
No more than you do or any
ventilation system does for airborne viruses and bacteria. Many people are susceptible to
dryness sometimes caused when an air conditioning system is badly designed or maintained
and the relative humidity is reduced too much. It's a fact that basically coughs and
sneezes spread diseases, but some people will blame anything for their ills rather than
understand the facts.
Please explain the difference
between air conditioning, comfort cooling and close control?
Air conditioning covers many things
but is mainly, heating, cooling, ventilation, fresh air, filtration and control of
humidity.
Comfort cooling mainly relates to
provision of just cooling to improve comfort.
Close control air conditioning is
really as the name implies, both temperature, humidity and air cleanliness are closely
controlled and often to fine tolerances if necessary.
The fuse keeps blowing on my air
conditioning - Why?
It could be that there is a problem
with the compressor and you are advised to contact us for further assistance. It could
also be that a fuse or circuit breaker has recently been replaced but the wrong
replacement (smaller rating) has been fitted. Check, but only if you are qualified to work
on electrical systems.
The air conditioning is running but
is not cooling/heating?
Many reasons, the simplest being
that you may have inadvertently set it to fan only operation. Unfortunately it may also
indicate a serious fault, Check your operating instructions but if no luck, give our
service department a call.
I
have lost my operating instructions - Can I get another copy?
Quite possibly, contact those nice
people at ACS and they may be able to send you copies or at least advise you how to
proceed.
What
is a heat pump?
A heat pump is a machine that by
reversing it's refrigeration cycle can provide heating instead of cooling. Because a heat
pump uses a refrigerant it can upgrade the heat in air at even -15ºC to a usable heat
source to heat buildings. Difficult to understand perhaps but imagine a domestic fridge or
freezer, reverse its cycle and that black grille on the back will be very cold whilst
inside will be very hot.
Heat pumps can extract heat from air
and water and are nearly always used to both heat and cool a building very efficiently and
economically.
What
is VRV or VRF?
VRV is a system developed and
designed by Daikin Industries and means "variable refrigerant volume". Daikin
protected the term VRV so other manufacturers use the term VRF "variable refrigerant
flow". In principle they both work the same and are extremely efficient, reliable,
energy saving ways to heat and cool all types of buildings with minimum installation time
or disruption.
The volume or flow rate of
refrigerant is accurately matched to the required heating or cooling loads thereby saving
energy and providing more accurate control.
In short, they are probably the best
systems currently available for mid to large applications.
What
does an inverter do?
An electrical inverter is used to
vary the frequency of the power supply from a normal UK 50Hz enabling fine step speed
control of motors (compressors) this in turn varies the quantity of refrigerant delivered
and hence variable cooling or heating capacity.
My
air conditioning is not working - What can I do?
One of the most common causes of
failure is that some one has switched off the power supply. So check that fuses circuit
breakers and isolators are all OK and working.
Another common cause is blocked air
filters, so check they are clean and are regularly kept clean. It helps to refer to the
manufacturers operating instructions as well.
If all else fails and you are still
having a problem, contact our service department.
What
is COP?
Coefficient of Performance, which is
the ratio between the power input and power output. For example a modern heat pump will
provide 3.5kw of heat for 1kw of electrical power input. Therefore the COP is expressed as
3.5 - 1.
What
is EER?
Energy efficiency ratio is used to
express the relative efficiency of a heating or cooling device by dividing the heat output
by the power input. The higher the ratio compared to others, the better the system is.
What is Energy Labelling?
Energy labelling is a new way of
allowing consumers to easily compare and rate the efficiency of air conditioners and
systems, similar to that used for domestic appliances such as fridge's and washing
machines etc.
The
air conditioning is running but the airflow is much lower than I remember?
Have you cleaned your air filter? -
The most important user maintenance is to keep those air filters clean.
