BetaAir Frequently Asked Questions |

- How do I work out which air conditioner I need?
- Cooling power of mobile air conditioners is measured in BTUs or Watts. As a rough guide, multiply LxWxH of the room. If in feet x 4 = Btu/h required. If in metres x 40 = watts required. Allow for extra heat gain, too.
- How low can I make the temperature?
- There are limits to how cold the room temperature should be, so all machines have a lower operating limit. On most machines this is around 21°C.
- Where can I use a mobile?
- Mobiles are perfect for the home and the office. They need no major installation and connect into a normal 13 amp socket. Ideal for rented property because they do not bECOme part of the fixtures. They can be taken from room to room.
- What else should I consider when deciding which air conditioner I need?
- In addition to room size it is important to take into account:
- Equipment e.g. computers, photocopiers.
- Large window areas, especially south and west facing.
- Number of people in the room.
- What happens if I buy an air conditioner smaller than is needed?
- When the head load in a room is greater than the units cooling capacity, an air conditioner will be operating as a comfort cooler or spot cooler, taking heat out of the room but not actually reducing the temperature
- How much does an air conditioner cost to run?
- Most single unit air conditioners have an input power of below 1kW per hour, therefore the cost would be about 7 pence per hour. Split systems have inputs around 1.3kW per hour so would cost in the region of 10 pence per hour to run on full power.
- Where does the heat go?
- Air conditioning units actually take heat from the room and expel it to the outside. Single units do this by means of the 1 metre flexible exhaust hose. Split systems discharge the heat via the external condenser unit.
