Air-Conditioning and Heat Pump Systems
Whatever your air conditioning requirements, be it a small or large server/comms room, one or many offices, IT-classrooms, retail areas, surgeries, waiting rooms, or maybe a domestic conservatory or loft extension, etc, we can provide practical, appropriate and helpful solutions to your requirements.
Whether it is to be a small single room or a whole office block, there are several different types of Room Unit to choose from. We have indicated a selection below:
Types of Room Units
Recessed Ceiling Cassettes
The recessed cassette Room Unit is often the best selection, distributing supply air from the middle of the room. These units can be either the regular 4-outlet style (below left) or the special round-flow style, supplied by Daikin Industries, which has superior airflow benefits and is ideally suited to lower ceiling heights where reduced air speed from the unit is important to minimise draught concerns.
Where space in the ceiling void is restricted, we can often resolve this by semi-recessing cassette and fitting a collar around the exposed area to nicely finish off the installation (below right).
Where there is no ceiling void or very little ceiling void to recess a cassette, there is a unique style of Room Unit available from Daikin Industries, which is similar to the regular ceiling cassette except the Room Unit is finished with an aesthetic casing, intended for fixture beneath the ceiling where it would be visible to the room occupants.
The cased under-ceiling cassette can also be installed in mid-air, suspended from above, in those high ceiling/roof applications where the cooling is needed near to the occupied area, far below the ceiling/roof (above right).
Under-Ceiling Cassettes (1-Way Direction)
Depending on several factors, an under-ceiling style of Room Unit with a one-way blow outlet might be the most suitable. These units are particularly suited to offices where wall-mounted system cannot be accommodated, or a large duty is involved, and where the depth of ceiling void is inadequate to allow installation of a recessed ceiling cassette. They can also be suspended from the roof, arranged to serve the occupied area from the perimeter.
However, in most applications, a wall-mounted style of Room Unit is normally the simplest and cheapest installation. The equipment is the least expensive of the Room Unit styles described above and so the overall price is normally the lowest. There are some special finishes, such as mirror, or pictorial designs, where the regular unit is not quite acceptable as regards appearance.
Concealed (Ducted) Air-Conditioners
Where it is necessary to conceal the Room Unit from view, for example, in a hotel room or in some domestic installations, a ducted unit is available. The Room Unit can be installed above a suspended ceiling with a number of grilles to supply the filtered and cooled (or heated) air to the room, or it could be concealed above a wardrobe or behind a builderswork enclosure with just the outlet grille and return air grille visible. Though there is the extra builderswork involved with these arrangements, such as new bulkhead, access panel, maybe plastering, wallpaper or/and painting decorations, etc, the final appearance can be worth the extra work involved.
There are also occasions were the ducted unit can be used, for example, in a retail shed-type building where no suspended ceiling exists. The ducted Room Unit can be installed at high level, out of eye line, with a section of supply ductwork to direct the conditioned air downward, to the occupied zone (see above right).
Alternatively, the ducted air-conditioner can be
connected to a range of supply ductwork, stretching over the occupied
area, to provide good distribution of the conditioned air over a wider
The unit and ductwork can be painted to help these services
blend in with the appearence of the roof area.

Anti-Vandal Guard Units
Where the exterior of the premises is subject to
unwelcome visitors of a night, and the outside condensers must be
installed in insecure locations, it can be prudent to install an
anti-vandal guard around the outside condenser, which inhibits damage
to the equipment.
The guard unit also offers some extra protection
to people on your premises who might hurt themselves while
tampering with the equipment, and then claim on the owner's insurance policy.
The guard unit is demountable so as to allow access by authorised personnel for maintenance and repair work.
Heat Pump Air-Conditioners
Almost all of the air-conditioners on sale are 'heatpumps' which is to say that they can provide both heating and cooling for all year around operation. From the controller, one can set these systems for just heating, or just cooling, or left in automatic mode so that the air-conditioner switches between heating and cooling, as required, to maintain the desired room conditions. There is also a mode for fan-filter-only, and another to dehumidify the room without changing the room temperature.
Heatpumps provide very efficient heating: typically, with an electrical input of 1kw, the system creates 3kw of heating in the room. Compare this with a regular electric heater that draws 1kW of electricity and gives out only 1kW of warmth. There are many buildings heated with regular electrical heaters, pouring a business's hard-earned money down the drain, five days per week, all through the year.
New Inverter Systems and 'On-Off' Systems
are two types of air-conditioning equipment: the on-off type, and the
new Inverter type. We recommend the Inverters because they will save
approximately 30% in electrical consumption compared with the on-off
type of systems. In addition to these significant savings in
electricity, the government recognises these energy-efficient systems
and allows businesses to take advantage of certain tax advantages (see
our 'Tax Aspects' web page for further information).
domestic installations, there is also a reduced Vat rate of just 5% on
the overall price of the installation, rather than the regular 17.5% rate.
