Is your heating and cooling system outdated, noisy and costing you too much to run? New technology helps solve these problems

Heat Pump/Air Conditioners are well established in the work environment and a ‘must have’ for most businesses. Major technological advances in these systems over the last few years, however, means that most older units are considerably less efficient when compared with the new breed of systems using “inverter technology” and modern gases.  

Since heating and cooling is a major expense for most businesses it would be financially beneficial to upgrade to the more efficient technology if it were possible. Unfortunately, since the different refrigerant gases are incompatible and work at different pressures, upgrading has also meant replacing the gas pipes that link the indoor and outdoor units.

Obviously this can be a major expense. Especially if the indoor and outdoor units are far apart or involve complex/difficult pipe runs through walls and ceiling spaces. As a consequence the capital outlay for making these improvements has, more often than not, outweighed the cost-saving benefits.

Solution

Mitsubishi Electric has developed a unique and patented technology which allows the replacement of outdated and poor performing Heat Pumps/Air Conditioners (even other manufacturer’s products) with their modern and highly efficient equipment utilising the existing R22 and R407 refrigerant gas piping, thereby vastly reducing the cost.

How does it work?
 
Previously it would be impossible to swap out units because the different gases, pipe-lines and parts used are incompatible. Older gases, traditionally work at lower pressures and many have external copper piping with reduced wall thicknesses which are unsuitable for the higher pressure modern gas (R410A).

Mitsubishi Electric patented technologies have overcome these hurdles. Through a combination of an automatic pipe-cleaning process and the use of specialist coatings within the compressor to reduce friction and temperatures (that would normally destroy the lubrication properties of the oil), it is now possible for cost effective installation of modern and efficient Mitsubishi Electric units in place of outdated equipment.
 
Why upgrade?
 
Modern inverter heat pumps running on R410A gas can have efficiencies (COP’s) up to 4.78, giving vast running cost savings when compared to equivalent older fixed speed models, running on R22. Current Mitsubishi Electric high wall heat pump models all qualify for the Energy Star mark.

Although energy efficiency and performance are the main reasons for upgrading, other advancements and improvements can also be enjoyed:

•         Slimmer and more aesthetic designs
•         Lower noise levels
•         Increased control
•         Improved air quality
•         Better temperature management
•         Reduction in draughts

Future proofing

With the adoption of the Montreal Protocol by New Zealand and the implementation of the Ozone Layer Protection Act 1996 it is now illegal to import HCFC’s such as R22. This is already causing a shortage of the gas for older systems thereby affecting the ability to service these units. Eventually it will become impossible and new systems will be required anyway.

When?

Another major benefit of this replacement technology is that because only the indoor and the outdoor units are required to be changed, and not the pipe work, the upgrading process has minimal impact or inconvenience during normal working hours.
 
Who can benefit?

This technology allows for upgrade from simple single room systems right through to large, complex multi room workplace and office systems.
 
Example
 
Mr Wilson had two old air conditioners of different sizes and brands installed in different rooms that he wished to upgrade. Since the pipework was concealed in the walls and under external concrete when the property was built, it would have been, ordinarily, impossible to replace these units in their existing locations. Using the Replace and Reuse technology, two new Mitsubishi Electric units were installed quickly, painlessly, cost effectively and with no mess.
