Portable
/ Mobile Cooling - A Guide to equipment available
We
at 'Chillmech Limited' have been hiring equipment to Domestic
and Commercial sectors since 1995 and we now realise that selecting
the right equipment for the job is a 'Minefield' for most people
outside of the Air Conditioning and HVCA trade.
The
main problem is that there are so many different units available
now that we thought it best to provide a brief description of
various units to help you - the customer, select the best unit
for the application required.

Flexible
Hose (Monoblock) Type Units
Ideal for use in: Small Offices, Domestic, Schools and Colleges
Cooling Range: 1 kW to 3.5 kW Generally |
 |
| A
Small but efficient portable cooling appliance delivered to operate
in one piece (Hence the name Monoblock). The units will have a
sealed refrigerant cooling system which passes the room air through
a filter and a cold aluminium coil before returning it to the
room cleaner and colder. The heat produced from cooling the room
air is collected and discharged out through a 100mm (4")
flexible - Tumble drier type hose, which ideally should be vented
to outside through a doorway, window or purpose built aperture.
The hoses supplied with the units are not particularly long (on
average 1.6 metres) but they can be extended (slightly) by use
of an accessory extension package.
These
units are limited in cooling capacity by the amount of heat
and volume of air that can be effectively vented outside by
the discharge hose. Normally the cooling capacity is limited
to approx. 2 to 3 kW.
The
units will produce waste 'condensate' water during the cooling
cycle and this either drains into a small inbuilt catchment
tray, drains away by gravity drain (for permanent installations
this can be installed by others) or is gradually evaporated
out with the hot discharge air blowing from the unit.

SPLIT
TYPE - PORTABLE AIR CONDITIONING UNITS
Ideal for use in: General Offices, Large Domestic, Halls, Marquees,
Commercial
Cooling Range: 2.3 kW to 7 kW Generally |
 |
| These
units are provided in the form of two basic halves, one part is
positioned inside the room or premises, the other part - the 'Condenser'
section is positioned outside the premises in the open air or
inside a warehouse or void area ( Somewhere that the heat will
dissipate and not build up or affect other persons or equipment).
The distance between the two parts is limited to about 2 metres.
An 'Umbilical'
type services line is supplied with the equipment and this can
generally be separated (to pass through walls or openings) before
being connected up to the indoor section.
These
type of units are far more effective, offer greater cooling
capacity and are more secure in most instances as any opened
windows or doors do not have to be secured during 'Out of Hours'
periods.
Electronic
temperature and fan speed controls are generally supplied with
the units and can maintain the desired temperature range inside
a building as required.
Waste
water produced during the cooling cycle is pumped to the outdoor
unit and dissipated with the hot condenser air.
They
tend to be bulkier and heavier than most other units but this
is only due to the amount of equipment that is inside and necessary
for the cooling required.

EVAPORATIVE
- PORTABLE AIR CONDITIONING UNITS
Ideal for use in: General Offices, Large Domestic, Halls, Marquees,
Commercial
Cooling Range: Not establish able due to varying conditions |
 |
| These
'Coolers' or 'Swampies' as they are called in Australia operate
by drawing room air through a wetted filter pad (The pad is normally
made of a natural Aspen type wood or straw material). The general
idea is that as the hot dry air enters the wetted pad it draws
moisture away from the wetted surface, in doing this the humidity
increases but the temperature drops. They are very effective in
hot dry climates, but they tend to be fairly mediocre in the UK.
They are great for bigger areas, factories and Marquees etc.
A
constant topping up of the water tank is required, the warmer
it is the more often you have to fill it.
A
simple, effective, cheap method of providing some conditioned
air to larger areas. The energy required to operate the fan/pump
is all that is required so approx. 200 watts.
