Efficient means of providing heating as well as cooling.
	Most potential tenants will not be interested in an office building which does not have some form of air conditioning.
	All plant is located outside, allowing maximum possible lettable area.
	Any office with IT equipment and office machinery will require some form of cooling.
	All office buildings require heating.
	All new buildings must comply with Part ‘L’ Building Regulations.
	Staff will become intolerant of hot, stuffy, humid, working environments.
	Customers/clients attending meetings or presentations will have the same objections.

	Office Blocks, Business Parks, and other commercial sites will normally include air conditioning in the specification.
	Smaller buildings can be air conditioned using multiples of individual split systems, or Multi-systems.

Mitsubishi manufactures VRF Multi Systems for larger applications (KX and KXR type). These systems consist of multiples of indoor units connected to several outdoor units (maximum ratio is 40 to 1). This allows individual offices and open plan areas to be efficiently air conditioned, for both cooling and heating requirements. Cooling only operation is also available. All connections are by small diameter copper piping, which can be installed in risers and through ceiling voids.
It is also possible to alter the system layout if partitions are required to be moved, but it is important to make allowances for this at the design stage.

	KX - where all connected internal units operate on cooling, or on heating.
	KXR - where cooling or heating can be provided at any internal unit at any time. The KXR system also incorporates energy saving, whereby unwanted heat is removed from warm areas, and is transferred through the refrigerant medium to cool areas which require heating; for example, rooms on the north and south side of a building.

Occupied buildings can sometimes present additional problems, for example, if there are no risers, or ceiling voids; but with careful planning these problems can be overcome. There may also be difficulties with landlords approval, or with inadequate power supplies.

It is often necessary to carry out some or all of the installation work 'out of hours’. This can usually be accommodated, but will have cost implications. Specialist installers will negotiate with the client to establish a workable programme, to suit the client’s requirements.

3D supplies Mitsubishi air conditioning equipment to over 2000 air conditioning installation companies throughout the UK and Ireland. We know many installation contractors, large and small, who are geared up for different types of contract. 3D can recommend suitable installers to quote for the supply and installation in all areas.
