The Next Generation Of R22 Replace Technology Is Here
Story
Mitsubishi Electric has launched its second generation of R410A City Multi Replace models to offer an 80 per cent increase in COP (Coefficient of Performance), halve the install time and cut installation costs by up to 40 per cent, when replacing a 10-year-old R22 air conditioning system.
The new City Multi YJM Replace units join the existing splits Replace line up to offer one of the widest and most efficient replacement model ranges available on the market.
Mitsubishi Electric were the first manufacturer to offer R22 replace models in the UK and have over five years experience in the Replace VRF market and even longer in the splits sector. This new development completes the product range with 100 per cent of the City Multi, Mr Slim and M Series models now available with R410A.
The new City Multi YJM Replace model is a modular system which comes in both heat pump and standard size small module (22 – 100kW) and heat recovery in the standard larger model (22 – 33kW). All currently available City Multi indoor units can be used with the Replace model and there is also the potential to upgrade the R22 systems of other manufacturers in addition to Mitsubishi Electric equipment.
Once installed, the City Multi Replace system will perform automatic refrigerant charging ensuring the optimal amount of R410A refrigerant is used. Following this, the system performs an automatic flushing of the mineral oil whilst operating in either heating or cooling modes.
The system saves on installation time by using Mitsubishi Electric’s unique, patented flushing operation which takes less than 2 hours and involves sending an R410A gas / liquid mix through the R22 pipes to collect any residual R22 refrigerant mineral oil.
“The sale of virgin R22 was outlawed at the start of 2010 and with a total ban on R22 sales by 2014 at the latest, anyone operating older equipment may soon run into difficulties,” explains Philip Ord, Product Marketing Manager for Mitsubishi Electric. “These old systems may still work at the moment but they will need replacing before too long and operators can benefit immediately from lower running costs if they switch now.”
Many elements of the existing system can be used including all piping, control wiring and power wiring as well as circuit breakers. This allows installation time to be reduced dramatically by up to 50 per cent with disruption kept to an absolute minimum.
Substantial material cost savings can be made, as well as installation costs, and there is also less waste. Overall, a 40 per cent installation cost reduction can be made on a replace system compared to installing a new system. Replacing a 10-year-old R22 system with a same capacity modern unit will deliver up to a 45 per cent power consumption saving leading to a potential 80 per cent increase in COP.
“We have spent the last five years preparing the most comprehensive range of replacement models to offer anyone with an R22 system the simplest way of upgrading,” adds Ord. “No other manufacturer can deliver such a wide range of solutions to the R22 challenge.”
