Variable refrigerant flow (VRF) systems are widely popular in many countries around the world, but are only recently becoming more popular in the US. By contrast, Japan – the country that originated the technology – utilizes VRF systems in ½ of medium sized commercial buildings and 1/3 of all large commercial buildings. And as a residential system, VRF has proven ideal because of the small footprint required for these systems. Plus, with a ductless option, installation for retrofit applications is almost as simple as it gets.
Mitsubishi is one of the companies leading the charge of marketing VRF systems to the US currently (which began only in the past 3-4 years). The CITY MULTI VRFZ System is Mitsubishi's offering for a two-pipe simultaneous cooling and heating system (also referred to occasionally as a VRF heat pump system).
The principle behind this type of variable refrigerant system is similar to a water-source heat pump system in that the circulating fluid is used as a heat transfer sync between heat pumps, with excess heat rejected to an outside unit. The only exception is that for the VRF, the circulating fluid is refrigerant as opposed to water.

In addition, the system can be provided with ducted or ductless indoor units (similar to a mini-split system which most engineers are familiar with), and operate very quietly, according to the manufacturer. Because of these advantages, they've become popular for apartment buildings and hotel guest rooms. The zoned nature of this system eliminates recirculation of air between zones, but does require introduction of outside air for ventilation directly into each unit's zone, and depending on zone usage this quantity of air can very.
Now at first glance, people might think that this isn't an environmentally friendly solution due to the fact that there are increased levels of refrigerant being used when compared to a typical split system… however the increased levels are minimal compared to the amount of cooling/heating the system provides. This is the basis for the LEED Energy & Atmosphere Credit 4, Enhanced Refrigerant Management. A project I recently worked on that included a VRF heat pump system is anticipated to earn this credit; with a total calculated refrigerant impact per ton of 54.6 (less than 100 is required to earn the credit).
One of the biggest advantages of the CITY MULTI system though, is the energy efficiency. Mitsubishi's INVERTER compressors ramp up quickly to meet the cooling or heating demand in the zone, then based on feedback from the system controls and sensors the INVERTER varies it's speed to maintain space setpoint, saving energy when the unit is only required to operate at part-load condition (97% of the time in most locations, according to the manufacturer).

Enjoy fresh hot water on demand. No more storage cylinder; you can free up valuable space, reduce your running costs and say goodbye to cold showers. Paloma Continuous Flow Gas Water Heaters allow you to enjoy all the fresh hot water you want, when you need it. Therefore you only pay for the energy you use, which is more efficient use of energy compared to storage water heaters.
Healthy water is important. Imagine using hot water that is fresh, not sat in a cylinder gathering all sorts of impediments, hot water that is pre-set to a safe temperature, that won't run out. The Paloma Eternity range of heaters provide all this, plus they operate on LPG or Natural Gas; relying less on increased electricity demands.

All models in the Eternity range include:

  • Quality (Q) Function provides superior temperature control with minimal water temperature fluctuation
  • 5 Star Energy Efficiency Rating – providing you with economical hot water
  • Frost Protection as standard • Built-in safety features including Flame Failure Device, Overheat Limit Switch and Water Pressure Relief Valves
  • 3 year parts and labour warranty

Solar boost:
16, 20 & 27L models may be used as a hot water boost in conjunction with most solar water heating systems. The Eternity water heater is connected in series with the storage cylinder, boosting the water temperature during low solar gain, delivering an uninterrupted hot water supply.
