A revolution in heat pumps for trade and industry.

 

There’s a new force in heat pumps for commercial and industrial applications: System Zero. Forget “either/or” – System Zero is the first series-produced heat pump to combine various heat sources, including waste heat, and regulate them for maximum efficiency. All while running on the environmentally friendly cooling agent propane.

Facts

  • Air-to-water and brine-to-water heat pumps in a single housing
  • Combined heating and cooling function (reversible technology)
  • Comfort throughout buildings up to 1,000m² (including hot water)
  • Environmentally friendly propane cooling agent
  • Via air-to-water circuit:
    It uses air, a constantly available heat/cold source
  • Via brine-to-water circuit:
    It uses geothermal energy and waste heat, and allows multiple sources in parallel
  • Intelligent control of air and brine sources:
    Through alternating or parallel operation is always efficient and always automatic

Zero waste heat wasted.
Zero cost explosions.


Waste heat isn’t wasted any more –
– in fact it helps save costs for heating and cooling. System Zero.

„You can’t make an omelette without breaking eggs,” goes the old proverb. And if you’re heating or cooling, you’re wasting valuable energy. Whether it’s a computer centre, cold store or apartment complex, large buildings and commercal and industrial facilities produce a lot of waste heat. That’s hardly to be avoided, given the laws of physics. But does the energy really have to go to waste? That was the question that led a team at Glen Dimplex Thermal Solutions to come up with an unusual solution: System Zero. Zero waste heat wasted. Zero fear that heating and cooling costs will go through the roof. System Zero is the world’s first large-format propane heat pump system that draws energy from various different heat sources, especially waste heat sources, potentially even in parallel. The result? Radically efficient energy usage. Radically lower energy costs.

How we came up with System Zero.
It was a cold, rainy October day in 2012. Maik Heydrich was on his way back home from his 220th customer visit. To date he had developed 220 different tailor-made models for cooling computer centres, or used geothermal energy to heat whole apartment complexes, or set up systems to supply warehouses and their offices with heat. And for the 220th time, Heydrich asked himself the question: can’t we do more? Can’t we combine different technologies and construction principles even better into one highly efficient overall system... ideally one that also incorporates waste heat? It was a thought that Maik Heydrich just couldn’t shake off as he drove through the rain. “It was the loss of waste heat in particular that had always bugged me,” he explains. “That was the same for all of us at Glen Dimplex Thermal Solutions: we just hate losing energy.” Instead of driving home, Heydrich headed to the office. A night at the drawing board followed. The idea had taken root. An idea that would revolutionise the heating and cooling of commercial and industrial facilities as well as large buildings – in an extremely cost-efficient way.

Six months later came the revolution in heating and cooling.

The heroes of the refrigeration circuit

The next morning Maik Heydrich called together his team of experts under Project Manager Dieter Müller and Engineer Uwe Steeger. Together they kept tinkering – and developed a plan for a heat pump that could do more than any other available heating solution. First, the new system would use at least two different heat sources, including waste heat. Second, the system would constantly optimise itself thanks to clever regulation, and depending on requirements decide which source should be tapped and in what quantity. This would guarantee maximum efficiency at all times. Third, the new system would naturally cool as well, thanks to its reverse circuit. Fourth, the new system would use the environmentally friendly cooling agent propane. Also, customers would be able to use the new system in a radically simple way: no-fuss installation, no maintenance woes during operation. And, at the same time the, new system would be highly flexible so it could fulfil as many different tasks as possible – in the warehouse, in the apartment block, in the computer centre. It didn’t take long to come up with a name for the new system: System Zero. Zero as in zero restrictions, zero difficulty, zero waste, zero problems, zero cost explosions. Just six months later the prototype was ready.

Plan System Zero of GDTS

Technically speaking, System Zero hits the jackpot. “External air is used as the primary heat source,” explains Heydrich. “A brine circuit uses other heat sources, such as geothermal energy, and above all waste heat.” In the past the only options were air-to-heat or brine-to-heat pumps. What does combining the two offer? “The best of both worlds – depending on requirements!” says Uwe Steeger. “And that goes for normal load as much as full load.” That’s particularly apparent when the system is used in apartment blocks. System Zero can use air as a heat source down to an exterior temperature of 2 °C. At lower temperatures, and when the demand for heating is greater, it switches over to the ground, a constantly available heat source, via the brine circuit. “The control technology recognises precisely when it make sense to do so,” says Dieter Müller. The brine circuit can draw energy from other waste heat sources besides the ground, too. As a result, System Zero is suitable for use in many different settings. Anywhere, in fact, where previously unused heat is available. In the warehouse of a restaurant chain the heat can come from the refrigerated section, in the computer centre from water- or air-based server coolers. “In both scenarios System Zero can use these sources to heat or even cool rooms more efficiently than an air-to-heat pump could on its own,” says Müller admiringly. The cost savings? “Up to 25%” And that’s all with an amazingly low initial investment. “That brainwave in the car really paid off,” says Heydrich.
