18,000btu (4.53kW) Cool & Heat Window Air Con Unit
OUT OF STOCK
Price: £597.01 incVAT

This high-powered air conditioning unit is installed through a wall (<20cm thick) or window and is sat on brackets with two thirds of the unit hanging outside the building and one third inside.

Unlike a split system air conditioner, this removes the need to install separate internal and external elements as both jobs are done by the one unit. And as this model also incorporates a heating function that provides up to 5.2kW of heat, it is sure to be as useful in the winter as it is in the summer.

Also, unlike a portable system this removes the need to leave a window slightly open to vent the hot air and it doesn't require any manual condensation drainage as it drains externally.

A remote control provides full control over all operations, including a timer feature that automatically shuts down the unit after a preset period.

This type of air conditioner is very convenient for rooms that have sash windows, as the unit can be placed on brackets through the window with the sash window simply lowered onto it and blanking plates (not supplied) put on either side to seal the window for maximum cooling.

This air conditioner has thermostatic control so will switch itself on and off depending on the ambient internal temperature and will cool a room up to 40m2.

The installation of this unit through a wall will need to be handled by someone competant in DIY as it will involved creating a hole through an external wall large enough to fit the entire unit.

These units are popular in conservatories as they can be installed through the supporting brickwork around the bottom of the conservatory.

 How does this work?


An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, R407C, to provide cooling.


This is how the evaporation cycle in an air conditioner works:



1. The compressor compresses the refrigerant, causing it to become hot, high-pressure gas (red in the diagram above).


2. This hot gas runs through a set of coils so it can dissipate its heat, and it condenses into a liquid.


3. The refrigerant liquid runs through an expansion valve, and in the process it evaporates to become cold, low-pressure refrigerant gas (light blue in the diagram above).


4. This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air inside the building.


Mixed in with the refrigerant is a small amount of a lightweight oil. This oil lubricates the compressor.


A window air conditioner unit implements a complete air conditioner in a small space. The units are made small enough to fit into a standard sash window frame. You close the window down on the unit, plug the unit in and turn it on to get cool air. Alternatively they can be placed through a hole in a wall. If you take the cover off of an unplugged window unit, you will find that it contains:


A compressor
An expansion valve
A hot coil (on the outside)
A chilled coil (on the inside)
Two fans
A control unit



The fans blow air over the coils to improve their ability to dissipate heat (to the outside air) and cold (to the room being cooled).
