Introduction - NOBOCOOL NC-49DP User Manual

INTRODUCTION

This portable air conditioner can alter the room temperature and humidity. It has multiple functions of cooling dehumidifying
(drying) and fan ventilation, and can be moved from room to room and transported from building to building easily.
The air conditioner can maintain set room indoor air temperatures between 18°C and 32°C. The set room temperature is
displayed on the remote control and in the control panel on the unit. This does not mean that the air conditioner will necessarily
reduce the actual room temperature to the set room temperature.

HOW YOUR NOBOCOOL
REFRIGER TED AIR CONDITIONER WORKS
Air from the room is drawn into the air conditioner, cooled by
refrigeration, and blown into the room through the front grill.
Hot air is blown outside through the exhaust hose, using the
window kit supplied with the air conditioner.
Hot air must be exhausted outside the room being cooled,
or you will not cool the room.

VARIABLES INFLUENCING THE COOLING
EFFECTIVENESS OF THIS AIR CONDITIONER
The ability of the air conditioner to cool the air in your room depends
on a number of variables. The critical variables are:
1. Orientation of the room to the sun.
Rooms facing North and West are exposed to the midday and afternoon
sun, and are the hottest in the house. Rooms facing the morning sun
(East), and away from the sun (South), are the coolest in the house.
2 . Insulation
Insulated roofs and walls reduce the amount of heat entering the room.
Windows admit heat into the room. This heat can be reduced if the windows are
protected from the direct sun (eg by outside blinds, well lined inside curtains, pergolas, thick foliage etc).
3. Air Draughts
Rooms protected from draughts are more easily cooled. Windows and doors must be kept closed.
4. Multi Storey Buildings
In multi storey buildings, upper storey rooms are usually hotter and therefore harder to cool than
ground floor rooms.

SIZING GUIDE
In general, the higher the cooling capacity (BTU/kW) of an air conditioner, the bigger the room it
will cool.
This 17,000 BTU air conditioner, subject to the variables explained in box 2, can effectively cool
rooms with a floor area of between 16 and 36 square metres.
Example 1:
Uninsulated upper storey
room with one West facing
external wall.
In this example, the air
conditioner is suitable for
effectively cooling a room
of up to 16 square metres.
