Making green personal
By Jayashree Mendes
Buying green is becoming a rage. Barely a day goes by without the rollout of a environmentally green product. Right from electric cars to waterless car wash to low electricity consuming lights… you name it and there is a product available.
Perhaps the products that help one save energy appeal to those who value their future environmental benefits. But there is another side to this. Despite tangible financial rewards, most people do not make even small environmentally sound changes at home, such as installing energy-efficient light bulbs or not leaving the television on standby. Reports brought out by global consulting firms show that most people are concerned about climate change. But few are willing to convert their words into deeds.
However, that is not deterring manufacturers from launching new products (while phasing out old ones) that are green in nature. But they come at a premium. Most often, consumers who want to buy green and reduce their impact on the environment find that their earth-minded sentiments die on the vine. Businesses, on their part, need to do a lot more to educate prospective consumers turn their talk into walk.
In spite of this, sustainability has caught on. Websites of manufacturers making green products have an entire section dedicated to explaining the long-lasting benefits of using environmentally-friendly products. Moreover, corporations and consumers can real multiple benefits by going green. They can reduce their energy consumption, lessen their risks, meet competitive threats, enhance their brands, and increase their revenues.
Businesses must make consumers aware that a product exists before they buy it. They must be convinced that it can serve them well too. In order that consumers improve their opinions of green products, companies must create ones that are equal to, or better than, conventional alternatives. Consumers must find it easy to track their savings from using a product, especially those that cost more.
The next three pages of this issue are devoted to a list of products that have proved to be green. Of course, given the limitations, we could focus only on a few products and companies.
Carrier has three products in the sustainable category. The Evergreen 23XRV chiller with Foxfire compression technology is the world’s first integrated variable speed, water cooled, screw chiller with industry leading IPLV’s of 0.33kW/ton. This chiller is 40% more energy efficient than conventional chillers.
The AquaForce 30XW-V comes with a capacity of 590-840kW and incorporates the Greenspeed technology. Utilising Greenspeed variable-frequency drive (VFD) technology, the inverter-driven, twin-rotor screw compressors allow the precise matching of capacity and building load changes and significantly reduce unit power input, especially at part load, achieving an Integrated part load value (IPLV) of 10. This efficiency level can reduce a building’s air conditioning energy consumption by up to about 30%.
Under Carrier’s light commercial R410a refrigerant-based product cassette range, four models have been launched – 1.5TR, 2.0TR, 3.0TR and 4.0TR. The 1.5TR and 2.0TR models are BEE four star labelled products. These units come with a voltage scanner that prevents the system from three-phase power issues. With digital scroll compressor, electronics expansion valve (EXV) and cordless remote (optional), this premium series of product is more advanced than existing ducted systems.
While the core of Daikin India’s product offerings remains an intermix of inverter technology coupled with robust customer service, it also endeavours to bring technological advancements that support eco-friendliness and lower operating costs into the product mix.
The need for greater refrigerants stem from the fact that introducing a new refrigerant requires various changes to the infrastructure of the wider air conditioning market. Another factor remains on the topic of equipment, which is already out in the market, wherein studies says that the replacement of existing hydrochlorofluorocarbon (HCFC) equipment with alternative refrigerant systems would require approximately 10 years covering up completely.
The manufacturer is assessing a number of substances as next-generation refrigerants, which will help sustain the environment in the longer run. Refrigerants like HFC32, a type of HFC with relatively lover global warming potential (GWP); HFO refrigerants, which also demonstrates low global warning potential (GWP) but come with cost and stability issues; and non-HFC substances such as CO2 and propane; are the currently outlined refrigerants which are expected to forward the cause of refrigerants in the foreseeable future.
While refrigerants are many, at the present moment, HFC32 is considered to be the most promising substance for use as a next-generation refrigerant in both residential and commercial air conditioners.

BAYER MATERIAL SCIENCE
Polyurethane insulation materials can reduce the energy consumption of buildings significantly and contribute to the reduction of greenhouse gas emissions. Makrolon stands for light weight and transparent polycarbonate resins and PC-sheets that open up entirely different design solutions compared to glass elements. Polyurethane coating raw materials are ideal for durable coatings in high traffic areas of commercial and industrial buildings. Polyurethane adhesives raw materials for structural wood elements make it possible to use wood as a renewable construction material instead of heavier structural materials commonly used in the construction industry.
Implementation of energy-efficiency in building systems is almost entirely dependent on effective thermal Insulation of the building envelope. Lloyd Insulations provide complete solutions for scientific thermal insulation of HVAC system elements like chilled water refrigerant lines, supply and return air ducting and air handling units to provide comprehensive energy efficiency to the built environment.
Under winter conditions, a hazard is the risk of condensation within the system. Detailing the insulation system design would involve proper placement of vapour retarder and attention to potential heat bridges and cold spots. Thermal insulation, by retarding heat flow, delivers the following benefits to a building enclosure: Helps maintain temperatures; reduces over-all cost of heating or cooling; keeps the temperature of the inner surfaces of buildings within acceptable limits to reduce possibility of their acting as “radiators”; and provides fire protection to metal structures.
