In closing there are many more advantages to the Mitsubishi Electric products on offer from simple internet connectivity to off site monitoring making air conditioning management an absolute pleasure for the service engineers and building owner and or developers. Mitsubishi would welcome any opportunity to present many more added feature and benefits if required.

The main feature of the product is its high energy saving capability, consuming up to less than 40% electrical energy than a typical constant volume air conditioning system available today. This efficiency is achieved using inverter technology throughout the system combined with simultaneous heat recovery.

Briefly, inverter technology relies on variably controlled inverter compressors and fan motors that adjust their speed to various demands put on the system during differing peak loads on any a given day. For example in common applications the air conditioning systems when in operation will run at maximum output. Once the desired temperature is reached it will switch off, as the temperature increases the constant volume system will need to re-start at which time it will draw a large amount of current to start to meet the desired temperature. Each time drawing amperages of around six to eight times higher than the systems running current, forcing the electrical demand curve to move sharply up and down during varying levels of operation. Notably, this continuous switching off and on will be happening all day and the more individual systems you have the higher the demand for electrical power.

However with regard to Inverter technology reliance on high energy consumption to start the compressor is not necessary, rather than instantaneously starting up at its maximum power the City Multi system will instead start by drawing a very low 8 Amps of current slowly winding up to its peak demand without the need to draw high amperages to get the compressor to its maximum output effectively. In other words, as the temperature within the space is met rather than switching off, the compressor slows down, maintaining its set point without the need to restart every time additional cooling or heating is required. This operation flattens out the electrical demand curve resulting in lower energy consumption.

WHY CITY MULTI VRF?

 Mitsubishi Electric Air conditioners have established themselves as a world class brand and is backed by continuous research and development to meet a wide range of end user needs. This motive stimulated the introduction of the City Multi brand as a sub brand to the Mitsubishi Electric family of air conditioning equipment, offering class leading innovation to suit various markets and their ever changing requirements - from installation space to electrical efficiency. The City Multi product has been well received internationally and has found phenomenal success in Asia, UK, Europe and Southern Africa.
