Eco-Friendly Air Conditioners for the Climate Conscious

Southeast Asia has experienced a decade-wise temperature rise since 1960 and this rise in temperatures has rapidly spiked up cooling demands across the region. And, if left unchecked, this growing demand will render air conditioners as consumers of 40% of the region’s electricity production by 2040. To top that, there is a major shift in Southeast Asia’s geographical concentration, wherein natives are migrating in big numbers to urban areas. The urbanization has ensued increased deforestation to accommodate the new entrants as well as the establishment of farms to feed the growing mouths. Deforestation is notorious for increasing greenhouse gas emissions. In fact, it is the prime generator of greenhouse emissions in major countries, such as Indonesia, and the emission levels are even more than those generated by fossil fuels. However, fossil fuel emissions pose their own challenges and its ramifications are soon catching up.

Traditional cooling technologies require higher utilization of fossil fuel, such as coal- the region’s primary electricity generator, to the tune of 80% – which, in turn, hikes up carbon emission. A high level of carbon emission not just pollutes the environment but is also driving the country into a new climate regime, making the current cooler months of today warmer than even the hottest months of the mid-nineties.

Switching to better cooling solutions will not just ensure higher occupant comfort of urban dwellers, but also significantly lessen the impact on the environment and bear fantastic economic benefits. A 100 TWH reduction in energy consumption, which is equivalent to the energy produced by 50 coal power plants, will result in $12 billion in savings annually.

And while new national and international norms are underway, numerous technological innovations and their mindful applications are making present-day air conditioners much greener. Take, for instance, the Toshiba SMMS-7 VRF has been specifically engineered to provide higher environmental benefits with multiple features that align with the needs of today.

Here’s how the SMMS-7 VRF checks all the requirements of a green air conditioner.

Optimizes Energy Consumption

Compressors are the biggest energy guzzlers. Armed with a twin rotary compressor, the SMMS-7 VRF boasts of better part-load efficiency and through smoother operation and more convenient oil supply, which is attributed to the descending of compression position. At different frequencies, the twin rotary technology completely restrains excessive and inefficient compression phenomena so that each revolution is highly efficient. Its intelligent VRF control is operated and managed through the outdoor microcomputer. The control monitors the refrigerant usage of indoor units and precisely control the opening of the pulse modulating valve that is found inside each indoor unit. It responds to the operational load changes of the total system. What this translates into, is that with 300 independent sensors relaying information back to the outdoor unit, the SMMS-7 VRF can quickly and accurately response to a variety of conditions in order to achieve maximum energy efficiency and maximum user comfort. By ensuring better refrigerant distribution, not just throughout the indoor unit, but also better control on compression temperature and volume at the outdoor unit, the improved VRF control works in favor of both building owners and the environment.

What this translates into is that the outdoor unit strategically responds to the indoor cooling requirements, using and compressing only the necessary amount of refrigerant. This eliminates energy wastage to reach part-load efficiency and reduces the on-off cooling cycle, thereby maintaining the optimum level of cooling needed for occupant comfort.

Adapts to Existing Space Availability

Urbanization and cramming up of spaces is one of the key concerns in Southeast Asia. With a population overflow, installing traditional air conditioners that take up a sizeable amount of space, whether in the basement or on the ledge impede architectural developments that could have otherwise paved way for structured settlements. The piping and ductwork required for installing air conditioners too demand considerable space. With the strategic piping design, the SMMS-7 VRF has done away with the need for ductwork completely, and its compact unit is built with a smaller-yet-more-powerful compressor that doesn’t require wider space occupancy. Additionally, with a range of solutions, such as wall-mount air conditioner; ceiling cassette; and slim ducted units, you can choose one suiting individual residential and commercial needs.

But what really makes the SMMS-7 VRF a green air conditioner from a space utilization perspective is its enhanced cooling capacity, to the tune of 60HP per system, which means that there need not be an active plant room- the biggest space consumer. Plus, its 200% Diversity Factor now connects a higher number of indoor units to fewer outdoor units, resulting in the same performance without involving more units.

Better Environmental Payoff

At Toshiba, we constantly innovate to improve not just service efficiencies but also production efficiency. High-efficiency manufacturing is pursued to minimize resource inputs in production processes, eliminate unnecessary tasks in manufacturing processes, and reduce to minimum emissions into the atmosphere and waters, thus simultaneously reducing environmental impacts and costs. In the research and development of new product, Toshiba Environment Policy mandates Environmentally Conscious Products, which are designed to minimize environmental impacts throughout all stages of their lifecycles, including during procurement of materials, manufacture, distribution, use, disposal, and recycling. The SMMS-7 VRF has been diligently scrutinized across every stage to align with the pre-set lean methodologies to avoid level-wise and collective wastages. This ensures zero-to-no unnecessary material wastage and also improves performance. With the new liquid pipe temperature control algorithm and tankless design, SMMS-7 VRF uses up to 30% less refrigerant.

From a global, as well as a regional perspective, there is a pressing need for the entire human race to sit up and take note of the changing environmental conditions. As global warming hikes up the temperature, causing higher utilization of cooling solutions, traditional cooling solutions are, in turn, adding to the rising global warming levels. Adopting greener cooling solutions will drastically help to counter the concern while simultaneously promoting higher comfort levels for the heat-stricken citizens.
