The Jet
Air Air Conditioner carries the SABS
( South African Bureau of Standards ) Stamp
of Approval. Jet Air is one of the very few Air conditioners
on sale in
South Africa that carry this vote of confidence. Jet Air offers Peace of Mind
at Low Cost to You.
Here
are a few things to consider when choosing an Air Conditioner.
Examples are Size, Reliability and Cost. A Jet-Air Air Conditioner is Reliable and is sold at a very reasonable low cost. For selecting
the correct size, see below.. To check our full Brand Range of Air Conditioners Click Here
-
You
normally need one air indoor unit / Evaporator per room
-
An
Air-conditioner size calculator can be found here
-
If
your home or office has open areas you may be able to cool
multiple rooms using fewer Indoor units or,use a dual Air-conditioner
system
A
Simple Rule of Thumb Guide
Measure
the Length and Breadth and Height of your room, (in meters)
Multiply Length x Breadth x Height x 600
The result will give you the BTU's required to cool the room.
If the BTU result is somewhere between two Air-conditioner sizes, the best
selection policy is to use the bigger size Air conditioner

You
need to decide what type of air conditioner you need. A Low Cost Wall

A Jet Air Split
air conditioner is a low cost effective choice compared to central
air conditioning or Ducting type Air Conditioning. Although they
are typically more expensive than a thru- the -wall or window
air conditioner and you need an Air Conditioner Technician to
install the unit. The compressor is installed outside the building
and therefore the air conditioner are is quiet and much
more efficient. As a single 70mm hole is all that is required
, the security of the building is not compromised as in the case
of Non split or ducted type Air-conditioner AS already mentioned
, the only access hole in the wall is generally about 70mm" in
diameter. This hole can be re-sealed after installation of the
Air-conditioner

Jet Air Dual
and Split Air conditioner Systems
Low Cost Jet Air Dual
and Split Air conditioners are Air conditioners where the Evaporator
or indoor unit is separate from the Condenser / Compressor unit,
or Outdoor unit. They are the ideal air conditioning solution
for installations where adding Air ductwork is impractical or
too expensive. Since mini splits have no ducts, they avoid the
energy losses associated with ductwork of central forced air
systems. Duct losses can account for more than 30% of energy
consumption for space conditioning, especially if the ducts are
in an unconditioned space such as an attic.
Split-systems
can also help to keep your home safer since there is only a small
hole in the wall. Through-the-wall and window mounted room air-conditioners
can provide an easy entrance for intruders.
The
matched combination of indoor air handler and outdoor condenser
is efficient and easy to install.
Dual
zone Air Conditioning systems let you cool or heat two separate
areas or one large area.
The
Outdoor Air conditioning Compressor can be mounted on any outside
wall - a 70mm diameter hole is all that's needed for connecting
the two units. This hole can be re-sealed after installation
of the Air-conditioner
What
comes with a Jet-Air Air conditioner Kit ?
Normally
the Air Conditioner kit comes with three meters of Copper tubing
and this is enough for most installations, however if the run
is more than three meters then additional tubing needs to be
bought. This is what will connect the indoor and outdoor units.
The size and length of the tubing depends on how far the inside
unit is going to be from the outdoor unit.
Heat
Pumps
Most
modern air conditioners have a method to provide heat in the
colder winter months, Some of the older Air-conditioners have
electric heater elements but most of the modern air-conditioner
systems are designed to also be heat pumps or reverse Gas flow
systems.Dual zone and triple zone Air-conditioners are Multi
room Type air conditioners.Dual zone means that there are two
indoor units and triple zone means there are three indoor /Evaporators
units. It is best to get an indoor unit for each room you are
trying to cool but, if you are trying to cool open areas that
consist of more than one room you may be able to use one indoor
unit just make sure the BTUs ratings are enough to cover the
square meterage area of all of the rooms that must be services,
rather go slightly over than just adequate Heating methods: electric
heater and heat pumps
When
a unit says that there is electric heat, or strip heat, there
is a heater Element in the air-conditioner that uses the fan
to distribute the heat.
A
heat pump is similar to an air conditioner. However, instead
of cooling the air like it would in the summer it heats the air
and redistributes it into the room. This is also called “ reverse
flow air conditioning” outside gets cold, inside gets hot
Energy
Star
Energy
star is a American program that ranks products that are extraordinarily
energy efficient. Products that meet strict energy efficient
requirements determined by the EPA and the US Department of Energy
that do not compromise the performance and features of a product
receive the Energy Star logo.
EER
and SEER Ratings?
The
Energy Efficiently Rating (EER) is determined by The American
Air Conditioning and Refrigeration board that equals the ratio
of cooling capacity in BTUs to the power input in watts. This
rating determines the state of the air conditioner when it is
working. Resulting in cost saving.
Seasonal
Energy Efficiency Rating (SEER) is commonly used to measure air
conditioning. efficiency All air conditioners must have a SEER
rating of at least 10 to be sold in the America.
A
chassis is the base of an air conditioner. When the air conditioner
is described as fixed that means that the chassis does not slide
out. Air conditioners with slide out chassis are easier to repair
especially if the air conditioner is a through the wall air conditioner.
However , under certain conditions your security can be compromised
Noise
level
All
air conditioners will make some sort of noise however the modern
models are substantially quieter than older units. A Jet Air Split air conditioner is the quietest since the compressor is outside.
Air
flow
This
determines how you can move the vents to determine where the
air flows in your room. Air deflection means that you can move
the vents manually to the side and up and down manually. Air
swing means that the vents move automatically
An
Air-conditioner fan speed settings vary from air conditioner
to air-conditioner. Some units come with just two settings (on
and off) others, with low, medium, and high. Jet Air Floor Air-conditioners
A
floor Air-conditioner is normally assembled with the Indoor indoor
unit ( Evaporator ) and outdoor unit ( Condenser ) on the same
chassis,. To install these units a hole is made in the wall were
the chassis slots through and seals the hole. Due to the size
of the hole needed these units have fallen from popularity as
under certain conditions the hole compromises the safe aspects
of the room
Jet Air Portable
Air-conditioners
A Jet Air Portable
air conditioner is perfect for spot cooling or for areas that a central
air conditioner and bigger units cannot reach, also for area's
that has a high sun load and additional cooling is required so
as not to compromise the main air conditioning installation efficiency
Reverse
flow Air Conditioner or Heat Pump
For
climates with moderate heating and cooling needs, heat pumps
offer an energy-efficient alternative to a furnace and air conditioner.
Like your refrigerator, heat pumps use electricity to move heat
from a cool space into a warm, making the cool space cooler and
the warm space warmer. During the heating season, heat pumps
move heat from the cool outdoors into your warm house; during
the cooling season, heat pumps move heat from your cool house
into the warm outdoors. Because they move heat rather than generate
heat, heat pumps can provide up to 4 times the amount of energy
they consume.
The
most common type of heat pump is the air-source heat pump, which
transfers heat between your house and the outside air. If you
heat with electricity, a heat pump can trim the amount of electricity
you use for heating by as much as 30%?40%. High-efficiency heat
pumps also dehumidify better than a standard central air conditioner,
resulting in less energy usage and more cooling comfort in summer
months. .
A
heat pump is like a conventional air conditioner except it also
can provide heat in winter. In the summer, the heat pump collects
heat from the house and expels it outside. In the winter, the
heat pump extracts heat from the outside air and circulates it
inside the house using the refrigeration flow in the opposite
way. The heat pump works best when the outdoor temperature is
above freezing. Below that, supplementary heat often is needed,
at times a simple 100watt light bulb is enough. A heat pump can
save 30 to 60 percent less energy to supply the same heat when
compared to an electric heater with heater bars or oil heater
using resistance heating elements
COOLING CYCLE- Refrigerant passes through the indoor coil, evaporating
from a liquid to a vapour. As the liquid evaporates, it absorbs
heat, cooling the air around the coil. An indoor fan pushes
this cooled air through ducts inside the house. Meanwhile,
the vaporized refrigerant laden with heat, passes through a
compressor which compresses the vapour, raising its temperature
and pressure. The reversing valve directs the flow of hot,
high pressure vapour to the outdoor coil where the heat released
during condensation is fanned into the outdoor air, and the
cycle begins again.
HEATING CYCLE- The reversing valve changes and shifts the Valves around, causing
the refrigerant flow to reverse. Liquid refrigerant now flows to the outdoor
coil picking up heat as it evaporates into a low pressure vapour. The vapour
travels through the compressor where it is compressed into a hot, high pressure
