UK:  The new free pressure temperature app from A-Gas was a talking point at Chillventa 2014. iPad displays on the A-Gas stand showcased the pressure temperature app designed for use on iPhone and Android devices.  

Group Marketing Executive for A-Gas International Hayley Russell said: “We received a great response to our first free app targeted at refrigeration, HVAC contractors and service engineers ­– providing them with fast and comprehensive data straight to their iPhone or Android devices. There was real interest in how easy it is to access information available through social media channels and the difference this can make for engineers and contractors in the industry.

“There was also praise that such a wide range of refrigerants are referred to by the app. We will now listen to feedback from visitors and look at how the app can be developed further to help the industry.”

Information on environmental services available to A-Gas customers, including refrigerant reclamation, also prompted much interest on the stand. 

A-Gas refrigerant experts answered questions from visitors on technical and legislative issues surrounding refrigerant recovery. They also discussed the advantages of using the high capacity Portable Environmental Recovery System (PERSY)  which is available from A-Gas.

Initially designed for supermarket retrofit applications, the unit is offered as a service to any contractors needing to rapidly recover a large amount of refrigerant from a system.

The new high specification Carbon Dioxide (R744) refrigerant, eCO2, launched earlier this year by A-Gas, also drew appreciation. The refrigerant is produced sustainably from waste sugar beet, is UK-sourced, has excellent thermodynamic properties and is a green alternative to HFC gases like R404A. With a moisture content of 5PPM, A-Gas’ eCO2 is the driest CO2 commercially available.

UK:  McQuay UK has launched a new range of R410-based air-cooled heat pumps that feature reliable scroll compressors to deliver low cost, high efficiency heating and cooling for commercial and industrial applications.

With cooling capacities from 164 to 624kW, the flexible and compact ACZH non-inverter heat pump multi-scroll range significantly extends McQuay’s portfolio, which now comprises a comprehensive choice of efficiencies, sound level configurations and hydraulic modules, as well as an extensive variety of options and accessories.

ACZH heat pumps function in a wide range of operating conditions. In cooling mode, they work at ambient temperatures between -10°C and +46°C and, in heating mode, down to -17°C.

Using scroll compressors and axial fans to offer class A efficiency in heating mode, each ACZH unit has an exceptionally small footprint and low weight to increase siting versatility and make installation faster and easier.

McQuay's new range of R410-based air-cooled heat pumpsThe coefficient of performance (CoP) of the units is up to 3.3, with the maximum energy efficiency rating (EER) up to 3.04 and the European seasonal energy efficiency ratio (ESEER) up to a remarkable 4.74 on the reduced sound version.

Three sound level configurations are available in the range – standard, low sound (featuring a compressor sound cabinet), and reduced sound (combining the low sound version with a lower fan speed).

Each ACZH unit has two independent refrigerant circuits employing non-flammable, non-corrosive, non-ozone depleting R410 refrigerant, which results in low energy consumption, excellent product reliability and outstanding overall performance.

The units are controlled by the MicroTech III smart controller for easy integration with building management systems, including those operating Modbus, LonWorks, BacNet and Ethernet TCP/IP.

To maximise versatility, the ACZH range’s hydraulic module incorporates an optional factory-mounted single or twin pump and optional 500 or 1,000 litre buffer tanks, with or without a cabinet.

James Henley, Chiller Technical Manager at McQuay UK, said: “The energy and cost savings that our ACZH range of heat pumps offer put the range at the top of its class. By installing our top quality heat pumps in combination with conventional boilers or on their own, building owners and operators can make huge savings on their energy bills and reduce their carbon emissions.

“The lightweight ACZH range, in capacities up to 300kW, is around half the width of conventional heat pumps, meaning they can be sited in tighter spaces with less available access.

“On top of this, easy access to key components simplfies and accelerates installation, commissioning and servicing, and the choice of a broad range of options and accessories means we are able to cater for virtually any commercial application.”

UK:  Carrier Rental Systems, the leading temporary heating and cooling specialist, is urging industry and building managers to be prepared following predictions of an unusually cold winter.

Forecasters believe that a combination of reduced solar activity, limited artic sea-ice and a weak El Niño will result in bitterly cold conditions, catching industry and the public by surprise following a balmy end to the extended summer.

In anticipation, and as part of its strategic growth plan, CRS has expanded its fleet of temporary heating plant, to ensure it is ready to meet expected high demand for emergency heating. It has doubled capacity at its Thorpe headquarters, and invested in a new fleet of high efficiency boilers, integrated heating packages, fan-powered systems and radiant heaters.

Marc White, CRS director, says: “Leading forecasters, including the Met Office and Exacta, say that all the key models point to an untypically cold winter this year. It would hit particularly hard, given the Indian Summer, which inevitably lulls people into a false sense of security.”

He added: “Plant issues often come to light even with a gentle transition from Autumn to Winter. However, when intensely cold conditions arrive on the heels of an extended warm period, systems can go from standby to maximum capacity literally overnight, resulting in breakdowns and service outages that often prove costly and damaging for companies.”

Given the potential threat to productivity for manufacturers and the impact on the usability of buildings, he said it was an issue that companies and facilities managers need to take seriously and plan ahead for.

Temporary heating provided a way for companies to insure themselves against potentially damaging equipment outages, and also a means of topping up capacity when existing plant becomes maxed-out during prolonged cold conditions.

“From experience, we know that once cold weather arrives and is forecast to set in, our fleet gets committed very rapidly. Those who delay, in the hope that things will improve, may be left without the support they need when conditions remain cold for long periods.”

“We have invested in a significant expansion of our heating fleet. However, it is still finite and the only way to secure a safety net is to reserve the back-up required. It is a prudent and rational investment, and gives reassurance that eventualities are catered for.”

USA:  Star Refrigeration's new subsidiary Azane Inc, is to manufacture its climate friendly and high performance low charge ammonia freezers for the US market.

Azane Inc was launched earlier this year to provide a natural refrigeration solutions in light of the R22 phase out and potential HFC phase down for the US refrigeration industry. Star Refrigeration specializes in low charge packaged ammonia refrigeration systems, including the energy efficient air cooled Azanefreezer (a companion to the Azanechiller) that is designed for use in freezer warehouse.

The Azanefreezer, essentially an ammonia condensing unit, is a complete refrigeration package housed in one unit with two separate ceiling mounted coolers arranged for reverse cycle defrost. The unit contains two screw compressors, designed for industrial installations and located for easy maintenance access. Its low pressure receiver offers efficient operation and allows for a low charge of ammonia. The enhanced aluminium evaporator design provides better performance from the lowest amount of ammonia, without the need for any pumps as found in traditional ammonia systems.

The utilization of low charge, natural refrigerant ammonia, a zero GWP and non ozone depleting substance, should safeguard Azanefreezer from future environmental legislation. The system has a life cycle of 25+ years at maximum operational performance. It also uses reverse cycle defrost – currently the only system to offer this – which defrosts more efficiently.

Expanding on the benefits of ammonia, Derek Hamilton, Azane’s US Business Development Manager, says: “All Azanefreezer components have been selected to minimize the risk of refrigerant leakage, reduce refrigerant charge, simplify maintenance and prolong plant life expectancy. The Azanefreezer has been installed in public warehouses across Europe for over 20 years due to the phase out of R22. It is a fully tested and proven technology which has now been made available to US customers to aid the transition from ozone depleting refrigerants by 2020.”

The ammonia packaged unit has been specifically designed to operate with as little as one tenth of the charge of a traditional refrigeration system, therefore avoiding the burden of OSHA’s PSM and the EPA RPM requirements.
