Portable air conditioner units are a simple and economical alternative to a full air conditioning system. You would need a 13 amp socket and an outlet to vent the hot air. You can buy or hire from a wide range of portable air conditioners.

Hot air is vented through an open window or through a vent in the wall, using a discharge hose of about two metres in length.

Some portable air conditioner units have a strong compressor which blows hot air into a ceiling void. These portable air conditioners are particularly useful for rooms without windows, such as computer server rooms etc.

Portable air conditioner units, like dehumidifiers, extract moisture from the air. Condensed water gets collected in an internal tank, which is required to be emptied daily or once every two to three days depending upon usage. In some cases the unit can be connected to a gravity feed draining tube.
While buying or purchasing a portable air conditioner, you should look for features like a 24 hour timer, and a remote control, to adjust temperature and movement of air.

A portable air conditioner with a rotary compressor runs extremely quietly. You should also ensure that the unit has a good quality air filter to provide clean air.

Portable air conditioners with a cooling capacity up to 12000 BTU (British thermal unit) are suitable for use in home and small offices. For cooling of a larger area, a split portable air conditioner is most suitable.
