Story

Daikin Europe N.V. announces the introduction of VRV®III-Q the second generation of its Replacement VRV®III cost effective upgrade solution for systems based on the banned R-22 refrigerant. VRV®III-Q enables existing R-22 heat pump or heat recovery systems to be upgraded state of the art R-410A systems. Since the existing installation piping and in many cases also the indoor units can be retained, the installation minimum downtime and new investment is needed.

Cost effective and easy

From the onset of the R-22 ban, Daikin presented the market with a cost-effective solution in its first generation VRV®III-Q system, with which existing piping and in many cases the indoor units, could be retained. The new second generation, larger capacity outdoor units (up to 48 HP) have a reduced footprint, which is smaller than corresponding R-22 outdoor units, allowing their one-to-one replacement. As a result, existing power supply connections can also be retained.

VRV®III-Q is designed to operate the lower pressures suitable for existing R-22 piping whilst maintaining high energy efficiency. The use of automatic charging and cleaning obviates the need for new piping required in the past for system upgrades due to oil and contaminants in existing piping – even in the case of previous compressor breakdown. In many cases, only the outdoor units need to be replaced, allowing phased replacement, spreading of investment costs and minimal disruption to business operations.

VRV®III-Q is available in capacities of 5 to 48 HP (heat pump) and 10 to 30 HP (heat recovery) models. All existing Daikin R-22 and R-407C VRV® installations can be replaced and many non Daikin R-22 or R-407C installations can also be upgraded with this system. In addition to possible efficiency gains of more than 40%, system capacity can be increased without changing the refrigerant piping, allowing the system to adapt to increased cooling and heating demand.

Daikin Europe products are distributed in the UK by Daikin Airconditioning UK Ltd and Space Airconditioning plc.

Swish has now set 2011's environmental targets for its manufacturing and distribution operations. Under its ISO14001 Environmental Certification Swish has set and met challenging annual targets since early 2007.

Swishhas managed to reduce its carbon footprint by 3.5% in 2010 as a result of setting environmental targets under ISO14001 (based on Carbon Trust Level 1 methodology).

Swish SHEQ Manager David Watts said, “Since 2007 we've reduced the waste which goes off-site by a total of 72%, and this year we are looking to make at least a 10% reduction on 2010 levels.”

David says the company is proud of its efforts. “Any production scrap is recycled and most of our other waste like cardboard, paper, packaging plastic etc is picked up by specialist contractors and recycled.”

“But we don't just dump the rest in landfill,” he adds. “Since the beginning of 2010 anything we can't recycle has been picked up by a specialist contractor that sorts it out for us.”

The Swish environmental targets for 2011 are:

• Landfill -10%
• Electricity -6%
• Water -2%
• Transport Diesel -2%
• Heater fuel to show no increase in 2011

Crabtree Weatherseal accessories are waterproof to IP56 making them ideally suitable for any extremes of the UK climate, particularly a winter such as the one we’ve just survived. The IP56 rating confirms the products are proof against rain, including hailstones and snow, dust and small particles of dirt, in fact almost any medium that, for reasons of safety, should be kept firmly outside of the working mechanism of both socket outlet and switch. They are also available with an integrated RCD for even greater protection, in line with the latest 17th edition which specifies them in new and refurbished installations more widely now than ever before.

With April showers and more to cope with this spring, the IP56 rating of Weatherseal is paramount, and achieved by the surround to the socket being fitted with a specially formulated substance, impervious to water and dust. It differs from the gel-like substances used by other manufacturers as it is made from a new, specially developed and highly effective material, helping the switch retain its IP 56 rating after repeated use. When a standard 13A plug is fitted in the socket the lid can be easily closed, the whole outlet is sealed off against dust and dirt particles.

But for maximum safety outdoors or in a similarly hostile environment, Weatherseal waterproof RCD protected 13A sockets should be used.  In those parts of a house or annexe, such as a conservatory or utility room, or in a stand-alone building like a workshop or garage, where water might be sprayed for instance when washing down cars, they are key. In commercial applications where dust or oily deposits are present, their use is equally important.

The Weatherseal range from Crabtree is very affordable, and offers switches rated at 20A.  Socket outlets come as single un-switched, and twin switched DP 13A or 13A BS7288 RCD protected outlets also available. In common with many other Crabtree products, Weatherseal can be customised on site by using most items from the standard or Euromodule range.

‘Speed and flexibility’ is primarily why Looks Construction selected Marshall-Tufflex’s MT32 high speed underfloor prefabricated wiring system for the fast-track fit-out of units at Highbury Studios, a prestigious new mixed use residential and commercial development in North London offering flexible workspace, office, retail, restaurant and D1 space. This project forms part of the regeneration of Islington that included the Emirates Stadium and conversion of Highbury Stadium, the previous home to Arsenal FC, into the residential development now called Highbury Square.

Looks Construction of Dartford, Kent, has been contracted by Stadium Investement Ltd to carry out the building, mechanical and ongoing electrical fit-outs of the ground level units that range from 500–18,000 square feet, as they become rented to businesses and retailers and must be quickly transformed into offices or shops.

Each unit is bespoke and finished to the tenant’s specification. Modifications to internal layouts and power supplies are therefore needed to ensure that each one meets the differing requirements of the incoming tenant. Often this work is fine-tuned by Looks Construction as the tenant moves in, with the final positioning of desks, computers and lighting, for example.

Looks Construction established the need for a plug and play prefabricated wiring system to provide the essential speed and flexibility needed when installing power and lighting services to tight deadlines at Highbury Studios. As a result, the company explored the product options currently available.

“We researched the marketplace and found that alternative products did not offer the same level of flexibility as MT32 and other companies were not as good on lead times,” said Paul Jordan, of Looks Construction. “We therefore selected Marshall-Tufflex’s MT32 with the product supplied by Edmundson Electrical, Gravesend.”

MT32 is supplied as a total underfloor system taking complete cabling runs via a 32Amp plug and play connector to final outlets in pre-wired, pre-tested accessory boxes with male and female connectors, thereby eliminating hard wiring on-site, saving time and reducing costs. MT32 is a modular system, ideal for installations where power is fed from a main source and delivered over a wide area to a large number of outlets. Due to the flexibility of its design, it can accommodate up to three times the coverage of existing power track options and is also easily reconfigured where re-positioning of sockets is a possibility.

“The flexible conduit system to the accessory boxes is supplied to us in 3-5 metre lengths so that we only need to lift a small area of surrounding floor tiles in order to fit the boxes into the floor void,” added Mr Jordan.

“The boxes are all pre-wired and ready for plug and play connection to master circuit boards. We generally use ten circuits and 30-40 floor boxes with both ring and radial circuit cabling in the fit-out of a standard shell and core unit. With a fast turn around needed in every case, quick lead-in times were essential to us, as was speed of installation and flexibility. MT32 has delivered on all counts: it is fast to install, extremely flexible and it works very well,” he concluded.

The Highbury Studios scheme, part of the Highbury Islington Regeneration Project, is located just off the Holloway Road and has mixed residential and commercial space to great effect, with homes, shops, offices, restaurants, a supermarket, gym and studios for local artisans. The development also includes the new Emirates Stadium and Highbury Square and has been hailed as the ‘future of mixed use developments’.

Platon DE25 drainage and storage membrane has been specified as part of the green roof construction at the new Universal Studios theme park in Singapore!

Occupying about 35,000 m2, the green roof is one of Asia’s largest. Platon DE 25 was chosen as the drainage/water retention layer because the wide structural spans of the immense roof and the fast track construction of the park demanded that the chosen system was light and easy to install. The other components of the green roof build up included a fully adhered layer of Evalon PVC-EVA terpolymer waterproofing membrane, and a non-woven filter fabric which was laid over the DE 25, followed by a primarily inorganic substrate and selected drought tolerant plant species which require little or no maintenance.

The excellent insulation properties of green roofs mean they act as heat and sound shields, protecting building interiors from the tropical heat and reducing sound transmission. This not only reduces energy consumption, but also extends the lifespan of the waterproofing on the roofs.

Platon DE 25 is available in the UK and Ireland from Triton. Depending upon general climatic conditions and the plants used, Triton can now also offer Platon DE 40/500 for projects where a higher water storage capacity is required. Contact Triton via www.triton-chemcials.com

Providing householders with the advantages of electronic temperature control is easier than ever with the new Programastat wireless 7-day programmable room thermostat form Timeguard.

Wire free installation is ideal where it is impractical to run wires between a room thermostat and other central heating controls, and this new device can be relied on to transmit time and temperature programmes to its wall-mounted receiver box up to 60m away.

The room thermostat has an attractive illuminated display, showing temperature and status, while all the other controls are neatly hidden behind a drop-down flap. These enable householders to choose different settings for different days of the week, workdays and weekends for instance.

The Programastat range of electronic room thermostats and heating programmers also includes simple, hard-wired room thermostats and multi-channel heating and hot water controllers to provide all the options you will need to improve energy efficiency in your customer’s homes and, as you will have come to expect from Timeguard, the range combines superior, guaranteed performance with remarkably competitive pricing.

Behind the sleek exteriors of the range are sophisticated electronic controls that react immediately to changes in temperature, avoiding the over- and under-shoots (saw-toothing) of traditional thermostats. Even the simple room thermostats in the range (pictured right), with adjustable dials, are electronically controlled. The precise control these products exert can quickly add up to big energy savings.

Installation of all the products in the Programastat range is kept simple with Timeguard’s universal wiring centre box.
