Why the SMMS-7 VRF is the Solution to Modern-Day Cooling Challenges

Southeast Asia is severely feeling the brunt of global warming, with the rising temperature catapulting the region’s cooling demands. Additionally, as the countries develop to accommodate a higher concentration of urban population, they also have to consider occupant comfort for an improved standard of living.

However, cooling down Southeast Asia comes at a massive financial and environmental cost. The skyrocketing demand for air conditioners is leading to not just more operational cost, but also expanding energy demands, to the tune of 76% between the years 2007 and 2030. This puts the onus on not just government authorities but also manufacturers to innovate and offer cooling solutions that meet the demands of today. In line with that intent, the SMMS-7 VRF has emerged as a leading choice that caters to the dual requirement through a host of new and improved features.

Optimizing Energy Consumption

Air conditioners account for almost 40% of energy utilization in buildings, which could potentially balloon to a significantly higher number. And the building design can further increase consumption as greater vertical distance between outdoor and indoor units require the VRF outdoor unit to generate extra cooling output to meet the load. The SMMS-7 VRF’s smart and compact compressor promises better part-load efficiency – to the tune of 7.27 at 50% part load – and smarter energy usage. Better refrigerant distribution – both across indoor and outdoor units – ensures lesser wastage and optimum performance by reducing the on-off cooling cycle.

Better Reliability and Lesser Space Occupancy

Occupant comfort is an important aspect of better living standards. With due consideration to the environmental benefits, the SMMS-7 VRF also pays great attention to improving overall comfort and reliability. To ensure constant cooling despite errors, the SMMS-7 VRF comes with quick diagnostic, which reduces the need for lengthy fault investigation and repair, and reduces downtime.

For instance, the Wave Tool remote diagnostic application’s near-field communication (NFC) technology integrated in the SMMS-7 VRF makes accessing system configuration and fault log data easy and quick through a simple tap on the smartphone. Additionally, engineers can obtain data during the installation and service stage without removing the front panel of the outdoor unit, as the SMMS wave tool provides a complete set of data for installation and maintenance even when the ODU is not connected to a power source. Further, the system data can be transmitted from the site to the office – enabling remote troubleshooting together with the office support team, thereby drastically cutting down on time.

The accumulator has been refined to reduce pressure drops, leading to lower fluctuations and better temperature regulations throughout usage. Further, this redesigning has paved the way for a more compact compressor, which reduces the size of the unit. This size reduction, due to the smaller compressor and through other design reconfiguration prompts lower space utilization. Additionally, the SMMS-7VRF commands lesser space due to the elimination of ductwork and through efficient piping design.

Higher Operation Control

The SMMS-7 VRF 200% Diversity factor is one of its biggest strengths. By enabling connection of a larger number of indoor units to fewer outdoor units, it offers better-centralized control and the possibility of avoiding a separate plant room, which would otherwise have been a massive space guzzler. For instance, in the case of a hotel, the 200% Diversity factor allows up to twice indoor-to-outdoor unit configuration, which can cool common areas during the day and the suites and other rooms at night.

Furthermore, building owners and managers have the option to customize air conditioners to suit the individualized needs of the complex. Since the SMMS-7VRF comes with modular configuration, with each unit providing up to 60HP per system for different cooling needs, and in a variety of options – from wall-mounted, floor-standing, to ceiling cassette – they have the control on picking the option that is the best fit, which is contingent upon the ambient temperature as VRF performs better than nominal efficiency when the ambient temperature is lower than 35 degree Celsius; maintaining which could be a challenge for high-rise buildings in hot and humid climates.

Impactful Environmental Benefits

The effects of HVAC on the environment pose a massive challenge on a global level. In a bid to help do our part, Toshiba has strategically innovated and reconfigured aspects of the cooling solution to drastically lower footprints. From using up to 30% less refrigerant due to its tank-less designs and the new liquid pipe temperature control algorithm and better refrigerant distribution, the SMMS-7VRF reduces wastage. Further, by employing lean methodologies and curbing material wastage across every step of the manufacturing and installing the unit, the SMMS-7 VRF promises a lesser outflow of hazardous elements.

While proactively reducing footprints through better processes, improving the unit and optimizing performance also leads to much lower energy consumption. Currently, 80% of the region’s energy is sourced from fossil fuels, and a big amount of the energy is siphoned into cooling solutions. Therefore, reducing energy demands will incidentally lead to lower energy consumption, and subsequently, lesser emissions. Further, this reduction in energy demand will not just positively affect the environment, but will also have fantastic monetary benefits. It is estimated that up to $12 billion can be saved per year if energy consumption were to be reduced by 100TWH.

We stand at the brink of massive global changes that can tremendously affect not just our environment, but also our everyday lives. As Southeast Asia scurries to meet the growing cooling demands in the face of rising temperatures and a higher influx of natives to urban areas, it needs to actively consider various elements to effectively meet that demand. Through optimized cooling performance and proactive innovations to reduce footprints, the SMMS-7 VRF has earned its place as the preferred cooling solution in Southeast Asia.
