Are Cost Efficiency and Sustainability Mutually Exclusive?

Cost efficiency and sustainability are traditionally always meant to polar opposites- that helping the environment will hurt the business.  While going green does have a significant cost associated with it, businesses can stay profitable with innovative products, services, and business models.

Additionally, the assumption that only heavy industrial processes contribute to environmental pollution is a myth. Everyday household appliances, such as air conditioners, are major participants too- as they pump out carbon dioxide and other greenhouse gases. They are massive energy guzzlers, consuming almost 40% of a building’s energy requirement. And the problem is only about to get bigger as the global air conditioning market is speculated to reach $292 billion by 2025. Factors such as increasing global temperatures will subsequently create a higher demand for air conditioning, especially in tropical countries.

What this essentially translates into is higher carbon emission at a higher cost. Toshiba’s SMMS-7 VRF intuitively addresses both these concerns by integrating smart technologies that not only maximize energy efficiency but also enhance performance. 

Innovative Air Conditioners can Prompt Higher Cost Reduction with a Better Environmental Payoff

Modern-day air conditioners that minimize cost while simultaneously lessening the environmental ramifications need to have a three-pronged approach:

  • Superior performance
  • Higher energy efficiency
  • Lower cost implications

The SMMS-7 VRF aims to achieve this through re-engineered components and adoption of lean methodologies in production and design.

Better Performance with Smarter Technological Integrations

The changing temperature graph of tropical countries has triggered the need for adaptable air conditioning for enhanced cooling performance. A critical factor that affects the air conditioner’s ability to provide optimum comfort and performance is the ease and efficacy with which its systems satisfy Part Load Type C . While the general belief is that, most air conditioning systems should work to deliver the maximum cooling load required by any building (and air conditioners are built to meet that expectation too),  but it’s been observed that the actual cooling load is significantly lesser in the operative state. This means that optimizing part-load efficiency is as important – if not more – than achieving full-load efficiency.

Keeping in mind the critical role part-load efficiency plays in reducing cost and environmental impacts, the SMMS-7 VRF has undergone certain design and structural iterations optimize these key aspects. Leveraging its core technology of the twin rotary compressor, it ensures lesser utilization of energy to reach part-load refrigerant pressure through adjusting refrigerant compression to the required pressure. The thicker compressor has been redesigned to increase capacity and has a larger suction pipe diameter, that further enhances performance.

From an engineering standpoint, the larger capacity of the twin rotary compressor empowers it to deliver increased cooling capacity through a smaller package, which significantly reduces its footprint.

 Compact Size for Power-packed Benefits

 The SMMS-7 VRF may have a smaller frame, but it has vastly improved in its operational efficiency. This size reduction controls material wastage that could have otherwise turned into pollutants. It also offers greater installation flexibility, and maximizes usable space in the building. Traditionally, air conditioners occupy a sizeable chunk of space on the rooftop, in the basement, or on ledges of real estate properties.  The SMMS-7 VRF’s compact new design frees up these spaces for more productive usage.

Limiting Refrigerant Charge and Usage

The new technological blueprint integrates an improved oil detection system and an accumulator with a unidirectional valve, which limits the return of liquid refrigerant. The tankless design and liquid pipe temperature control algorithm together achieve a 30% reduction in refrigerant charge. Furthermore, new accumulator mechanism doesn’t need a U-pipe, which curbs pressure loss and improves performance efficiency.

Additionally, its intelligent VRF control enables the outdoor unit (ODU) to gauge, respond to the cooling capacity requirement and compress only the necessary refrigerant amount to meet the needs of the indoor units (IDU). This control of refrigerant distribution through IDU by manipulating compression temperature and volume at the ODU, encourages more efficient satisfaction of the part load thereby leading to better comfort and higher energy savings.

The SMMS-7 VRF’s stringent focus on improving full and part-load efficiencies, up to 4.82 at full load and 7.27 at 50% load respectively,  eventually slashes energy consumption by a whopping 20%. Its superior design boosts reliability and improves uptime, which positively affects the operational costs while keeping users cool.

Green Innovation at its Finest

The typical Southeast Asian climate places unique demands on today’s air conditioning needs which culminates into both- higher operational cost and emission levels. With the SMMS-7 VRF, Toshiba has created an innovative air conditioning solution that caters to the demand while simultaneously reducing the cost and ecological burden, resulting in a win-win situation for all.
