Throughout the ages, we have sought to improve the level of comfort offered by our
surroundings. In colder regions, we have tried to heat our dwellings and in warmer climates, to cool
them down because if we are not comfortable, we can neither work nor relax. But thermal comfort
vital to our well-being, is subject to three basic influences:
The human factor: Our clothing and activity level and how long we remain in the same situation
Our space: radiation temperature and surrounding temperature
▪ The air: its temperature, velocity, and humidity. Among these influences, the human factor is
somewhat unpredictable. The others can be controlled in order to provide that much sought
after feeling of well-being. Changing patterns in construction, working practises and internal
occupancy levels have created new parameters within which designers must operate. Modern
buildings for instance, generate far more heat than their predecessors of say, 50 years ago and
there are several reasons for this:
▪ Solar Infiltration: Developments in building technology have also given rise to an increased use
of glass - even when solar protective glazing is fitted, solar gains can be considerable.
▪ Occupants: Increasing numbers of occupants, each generating some 120W/h of heat, are
routinely stuffed into office areas.
▪ Electrical Appliances : Computers, printers and photo copiers, all part of the modern offices
scenario, also generate substantial heat loads.
▪ Lighting: Many modern shops could be adequately heated by their
lighting alone heat gains in the order of 15-25W/m² are not uncommon in Europe.
▪ Ventilation: Introducing the outside air into a building also introduces its temperature something
of a problem if it's 30ºC outside!
A heat pump extracts low temperature energy from the environment and increases its
temperature for heating purposes. Heat pump efficiencies are normally quoted as the coefficient of
performance of the system, these are typically in the range 3 to 5. In other words, extracting heat
from renewable sources requires just 1kW of electrical input in order to generate 3kW to 5kW of
heating output. Heat pump systems therefore, are 3 to 5 times more efficient than fossil fuel boilers
and are more than capable of warming a house completely, even during the lowest winter
temperatures. The increasing popularity of these heating systems is reflected by their
overwhelmingly successful application in the cold climates of Scandinavia.
Allergens are impurities in the air that can bring on an allergic reaction. In an urban environment,
a mixture of these allergens with other impurities present in the air – called adjuvant substances –
such as Diesel Exhaust Particles (DEP’s) produced by engines and Volatile Organic Compounds
(VOC’s) present in building materials, cosmetics, etc. can turn allergens into heavy allergens. These
in turn can have increased negative health effects such as aggravated symptoms and the triggering
of latent allergies.
The terms COP (coefficient of performance) and EER (energy efficiency ratio) describe the heating
and cooling efficiency of air conditioners. They indicate the ratio of heating or cooling provided by a
unit relative to the amount of electrical input required to generate it. Thus, if an air conditioner
generates 5kW of heat from a 1kW electrical input, its COP is said to be 5.0. Similarly, if an air
conditioner generates 5kW of cooling from a 1kW electrical input its EER is also said to be 5.0. The
higher the COP and EER, the more energy efficient is the equipment.

The inverter technology is integrated in the outdoor unit. The inverter technology can be
compared to the technology in a car: " The harder you push your accelerator, the faster you go."
An inverter unit will gradually increase its capacity based on the capacity needed in the room to cool
down or heat up the room. The non-inverter can be compared with switching on or off a lamp.
Switching on this type of unit will start to run on full load.
Advantages of the inverter technology:
▪ You reach much faster the comfort temperature you want
▪ The start-up time is reduced by 1/3
▪ You save a lot of energy and also money : 30% less power consumption
▪ Avoids cycling of the compressor meaning that there are no voltage peaks
▪ The energy consumption cost is reduced by 1/3 (compared to normal on/off units)
▪ No temperature fluctuations
Check to see if the air filters are clean. Also make sure the air inlets and outlets of the indoor and
outdoor units are not blocked.
When the ON timer is set, the air conditioner may start as early as one hour before the set time in
order to bring the room temperature close to the temperature set with the remote controller.
Check to see if the air filters are clean. Also make sure the air inlets and outlets of the indoor and
outdoor units are not blocked.
The amount of drained water varies depending on room temperature and humidity. A large
amount of drained water does not denote a malfunction.
The flap control varies the flap position depending on the operation mode such as cooling and
heating.
Check the following:
▪ Make sure the air filters are not dirty.
▪ Make sure the air inlets and outlets of the indoor and outdoor units are not blocked by
objects.
▪ Make sure the temperature setting on the remote controller is appropriate.
▪ Make sure the doors and windows are closed.
▪ Make sure the air flow and direction settings are appropriate.
▪ Make sure ventilation fans in the room are not operating.
Check the following:
▪ Make sure the circuit breaker is not turned off and the fuse is not blown.
▪ Make sure the power cord plug is connected securely to the service outlet.
▪ Make sure there is no power outage.
▪ Make sure the remote controller has new batteries.
▪ Make sure the timer is not programmed mistakenly.
Lightning and radiowaves can sometimes cause abnormal operations of air conditioners.
Cut off the power supply by turning off the circuit breaker, then re-supply power and restart the air
conditioner.

Cut off the power supply by turning off the circuit breaker, then re-supply power and restart the air
conditioner.
To reduce excessive load in a restart, the air conditioner does not operate for three minutes when
the ON switch is pressed immediately after it is shut down or when the operation mode (setting) is
changed using the remote controller.
The air conditioner conducts a "warm-up" operation first so that it won't blow cold air in the
heating mode. The fan starts operating after one to four minutes of warm-up operation.
(The warm-up operation becomes longer when the outside air temperature is low.)
The monitoring function forcibly operates the indoor unit fan for one minute.
After the air conditioner stops operating, the drain pump operates for several minutes in order to
discharge condensate from the drain pan (condensate receiving tray).
When power supply voltage fluctuates largely, the air conditioner may stop operating to protect
the equipment. (When power supply returns to a normal condition, the air conditioner resumes
operation after three minutes.)
