Q-ton responds to the pressures of high energy prices

The high costs of energy consumption in Australia is becoming a great concern for the food and beverage industry, from the agricultural sector all the way through to the manufacturing and processing sector.

A recent US Studies Centre report, It doesn’t have to be this way: Australia’s Energy Crisis, indicated that Australia was struggling to keep energy costs down, with its manufacturing companies across the country facing much higher electricity and gas prices than their counterparts in the US.

Further, a report from the Australian Food and Grocery Council released in November last year showed that high energy costs were among the leading causes of falling capital investment in the food and grocery manufacturing sector.

Food and beverage manufacturing accounts for approximately 14 per cent of energy consumption within Australia’s manufacturing sector, according to federal government statistics. And, for most companies within the food and beverage sector, energy costs represent around 15 per cent of the total cost of operation.

With energy prices continuing to rise, finding ways of creating greater efficiencies in energy use is becoming critical for food and beverage manufacturers looking to cut costs. Moreover, transitioning to energy efficient production can help a company establish its reputation as an environmentally responsible enterprise within the community.

The most energy intensive processes within the food and beverage manufacturing industry are conveying, refrigeration, cooling, air conditioning, heating and boilers.

Process heating and steam production are a significant source of energy consumption for manufacturers. According to Australia’s Department of the Environment and Energy, boilers alone can account for around 20-60 per cent of energy costs for the typical industrial plant in Australia and represent 35 per cent of all potential energy efficiency improvements.

Reductions in energy use in this area can be achieved by a number of means, including via boosting the efficiency of heat production, heat containment and improved heat transfer, and by recovering heat for reuse. Other possibilities include alternatives provided by innovative heating solutions.

Carbon dioxide (CO2) hot water pumps are relatively new on the market. They have the ability to efficiently deliver sanitary hot water at 65-90°C and provide significant carbon and energy savings to food and beverage manufacturers.

Mitsubishi Heavy Industries’ (MHI) Q-ton, an air-to-water heat pump, uses CO2 as a natural refrigerant for the delivery of hot water. Drawing air through an evaporator containing CO2 refrigerant – which absorbs heat through the air – the Q-ton uses a high-pressure two-stage compressor to raise its temperature. The heat from the refrigerant is used to generate hot water, which the Q-ton then stores in tanks.

Providing 3,000 to 100,000 litres of sanitary hot water daily, the Q-ton consumes 76 per cent less energy than an electric heater and 46 per cent less energy than a gas boiler, according to MHI. At the same time, it generates 74 per cent less CO2 emissions than an electric heater and 48 per cent less emissions than a gas boiler, making it both environmentally friendly and highly energy-efficient.

The Q-ton is able to be configured as a standalone unit as well as in modular configuration with up to 16 units in operation. Controllable from a touch screen, the unit offers programmability options and flexible operation not available with conventional hot water systems.

The flexibility of the Q-ton also extends to the conditions it can operate within. The unit can deliver hot water at low outdoor temperatures down to -25°C, making it suitable for food and beverage producers operating in cooler climates. This feature made it an optimal solution for the water heating needs of Shene Estate and Distillery, a 199-year old distillery located in Pontville, Tasmania.

Shene Estate produces award-winning gin and single-malt whiskeys, consuming approximately 6,000 litres every day, with multiple temperature changes required throughout the process. Ever-increasing electricity prices and expanding production saw the distillery abandon its instantaneous electric hot water heater and turn to the Q-ton.

Focusing on energy efficiency in this way not only can save food and beverage manufacturers in terms of the costs of production, it can also enhance a company’s reputation for environmental responsibility and enhance customer loyalty.

The difficulties of keeping the costs of energy consumption down will continue to be an issue for the food and beverage industry. However, as shown by the example of carbon dioxide hot water pumps, finding more energy efficient means of production can go some way to alleviating the burden.

Q-ton heat pump keeps costs low

The Q-ton water heat pump was introduced to the Australian and New Zealand markets to create sanitary hot water for commercial applications at outlet temperatures from 60°C to 90°C. Mitsubishi Heavy Industries Thermal Systems’ design team in Japan launched the innovative air source heat pump to allow for maximum efficiency with a minimal carbon footprint. Q-ton can be used in varying applications, including in food processing plants, dairy operations, bottling lines and breweries.

Mitsubishi Heavy Industries Air-Conditioners Australia (MHIAA) Air to Water manager Trent Miller said it represents the next generation of hot water production. “The Q-ton utilises CO2, a safe, natural and environmentally responsible refrigerant. The combination of CO2’s highly efficient, naturally accruing properties, enable the Q-ton to be far superior compared to conventional refrigerant heat pumps,” said Miller.

“Q-ton delivers outstanding performance as a solution based product. Q-ton supplies hot water from 60°C to 90°C at 100 per cent capacity at an outdoor temperature down to -7°C.”
With high efficiency rates and low carbon emission, Q-ton recovers heat energy from the air and can perform in extremely cold temperatures right down to -25°C. At temperatures that cold, it can continue to supply water at temperatures between 60°C and 90°C.

It is engineered to meet a range of demands including the need for medium to large sanitary hot water generation, low electricity consumption and high environmental responsibility. Q-ton represents the efficient solution to the old boiler type systems found in most commercial settings. A 30kW Q-ton produces in excess of 600 litres per hour.  The overall quantity of hot water production varies, as is dependent on the feed water temperature, the outdoor temperature condition and the water outlet setting temperature.

Less impact on the environment
MHIAA explains that the Q-ton is five times more efficient than an electric heater and six times more efficient than a gas boiler. It produces 48 per cent less CO2 emissions than an electric heater and 74 per cent less CO2 emissions than a gas boiler.

Q-ton heat pumps can be configured as stand-alone units or run with up to 16 units
in tandem, providing anything from 3,000 to 100,000 litres of safe hot water daily. Whether single or multiple units are used, the Q-ton system is controlled from a single, simple control panel that can be remotely installed for ease of access and operation. It can be installed as a replacement, addition or a whole new system.

Q-ton meets the requirements of a globally recognised environmental assessment method and rating system – Breeam. Refrigerant such as carbon dioxide preserves the ozone layer and has a low global warming potential rating. The system fits well with the latest building regulations, reaching a mark of excellence from Breeam. Q-ton absorbs free heat from outdoor air and amplifies it to generate hot water swiftly and efficiently. It generates hot water up to 90°C without the requirement for an additional electric immersion heater.
The system seeks to provide energy, cost and carbon savings. It is most efficient when cold water is used to supply the heat pump. For that reason, the cold feed water is provided to the heat pump, via the base of the storage stratified vessel.

Each storage vessel has five pockets into which temperature sensors can be fitted to detect the volume of hot water held in the vessel at any particular time. The programming of the control system, to hold specific volumes of hot water at different times of the day, is based on a balance of hot water demand and electricity tariffs, to ensure security of supply at minimum cost.

Saving businesses money  
Globally, Q-ton is making its mark on commercial spaces. Located in London’s Lancaster Gate and Bayswater, Mitsubishi Heavy Industries Air Conditioning Europe connected two Q-ton units to Lancaster Hall Hotel, which has saved the business daily running costs. The system produces 12,000 litres of water to cater up to 250 people on site. Lancaster Hall Hotel has reduced their running costs by 40 per cent compared to their existing boiler system. They have seen a 45 per cent saving on carbon emissions.

MHIAA helped the Shene Estate and Distillery in Tasmania save money with the Q-ton. The distillery produces gin and whiskey. Each day, it uses 6,000 litres of hot water for processes such as heating the barley mash. By working with MHIAA the company is able to produce hot water while reducing energy costs when compared to the distillery’s previous system.

Q-ton water heat pump – a hot water solution

Located in Pontville, Tasmania the Shene Estate and Distillery has been using locally sourced ingredients and traditional methods to produce some of Australia’s best gin and single malt whiskeys.

The distillery’s world famous Poltergeist Gin was awarded a Double Gold medal at the 2017 San Francisco International Spirits Competition and a Gold Medal and the World Gin awards in the same year, making it one of Tasmania’s most celebrated gins.

To produce the award-winning gin and single-malt whiskey, the distillery uses traditional distilling methods which utilises hot water to heat the barley mash.

Each day, 6,000 litres of hot water is required, initially at 90°C, with the temperature then reduced to approximately 64°C-65°C, the optimum temperature to dissolve sugars contained within the starch of malted barley.

Finally, the temperature is brought up again to 70°C at the end of the mashing-in process to dissolve enzymes. Given the growing production output of the distillery, this has resulted in a huge amount of water being used each day.

Conventionally, the water used in the above process is heated using an instantaneous electric hot water heater.

However, with ever increasing electricity prices, this was becoming expensive and unsustainable for the business.

While the alternative of gas was originally considered, given the estate is not connected to any gas grid, this was ruled out. An alternative and more energy-efficient hot water solution that could operate in the low outdoor temperatures was required.

The Q-ton is an industry-leading air-to-water heat pump that utilises natural refrigerant CO2 to deliver a reliable and highly efficient hot water solution in even the coldest temperatures.

The Q-ton heat pump draws air through an evaporator that contains CO2 refrigerant, which absorbs the heat in the air. 

The two-stage compressor compresses the refrigerant under high pressure to raise its temperature, while an on-board heat exchanger uses heat from the refrigerant to generate hot water, which is then stored in cylinders for sanitary use.

The Q-ton can deliver continued performance at low outdoor temperature conditions down to -25°C, making it suitable for the colder climates of Tasmania and allowing it to deliver accurate set point heated water, all year round.

The distillery’s existing water heater was only achieving a coefficient of performance (CoP) of 1, resulting in 48kW output from 48kW input.

The Q-ton can achieve a CoP of 4.3, and is able to deliver 30kW of output power while only requiring 7kW input at nominal conditions.

The Q-ton is also energy efficient to run, delivering huge reductions in both running costs and CO2 emissions, with the distillery anticipated to save 60 per cent per year on their energy bills compared to an instantaneous heater.

In addition to this, with the Q-ton’s remote-control scheduling functions, the Q-ton can produce hot water during off peak electricity periods that can be stored in cylinders for later use, offering further cost savings.

Q-ton energy consumption is 76 per cent less than an electric line heater and 46 per cent less than a gas boiler. It produces 74 per cent less CO2 emissions (47 tonnes) than an electric heater and 48 per cent less emissions (23 tonnes) than a gas boiler, making it environmentally friendly.

The Q-ton air-to-water heat pump can be configured as a stand-alone unit, or operate with up to 16 units in modular configuration, providing 3,000 to 100,000 litres of sanitary hot water daily and can be controlled from a touch-screen control panel.

This enables programmability and flexible operation not possible with a conventional hot water system that includes an electric line heater.

By working closely with the owners of the Shene Estate, MHIAA was able to deliver a reliable hot water solution that will reduce the operation’s energy costs and deliver reliable hot water, even throughout Tasmania’s chilly winters.
