At this year’s international trade fair for water, heat and climate, the ISH in Frankfurt, Glen Dimplex Thermal Solutions (GDTS) will present System C. GDTS once again proves its system competence with System C: Heating, cooling, domestic hot water preparation and heat recovery in one compact, modular system, custom-designed by the GDTS engineers. Especially for commercial projects. With a high degree of prefabrication. Highly flexible hydraulic solutions, perfect networking and a comprehensive range of services.    
   
Kulmbach / Frankfurt. GDTS focuses on the system, or more precisely on System C for the heating and cooling management of commercial projects. A modular, customised system based on state-of-the-art and climate-friendly heat pump technology. The heat output and cooling capacity are tailored exactly to the construction project and combined with suitable hydraulic components. There is also always the option to cascade the air-to-water heat pump for even greater design flexibility.

Just commercial properties usually have to be launched quickly. Because time is money. Thanks to the particularly high degree of prefabrication and modularity, System C is therefore perfectly suitable for series construction, for retail projects or even commercial properties.

One system. Wide range of applications.

System C is based on a particularly energy-efficient and climate-friendly heat pump, second to none on the market. The 60 kW air-to-water heat pump, placed outdoors, uses the natural refrigerant propane R290. And reversible functionality – thanks to a combined heating and cooling control system. To save space, the heat pump can be installed outside the building, e.g. on the roof.

The system is complemented by a compact hydraulic unit including buffer tank and optional domestic hot water cylinder. If the building is being renovated, the hydraulics can also be supplied in sections. The module width of 75 cm means they can easily fit through existing doors.

System C was specially developed for different application scenarios and controls three central functions: Heating or cooling in the Basic version, heating and cooling with domestic hot water preparation in the Advanced version. The Premium version can be used for parallel heating and cooling as well as for preparing domestic hot water. Integration into a heat recovery system completes the solution.

The innovation of GDTS: parallel heating and cooling.

The brine-to-water heat pump additionally integrated into the hydraulic unit functions as an energy shifter and ensures a demand-based energy shift between the temperature levels in cases where the building places very different requirements for heating and cooling. This means the system offers the greatest possible energy efficiency with low power consumption.

Sustainable and future-proof.

The latest F-Gas Regulation also entails drastic changes for commercial applications. Refrigerants with a high GWP (Global Warming Potential) will no longer be approved. This particularly affects synthetic refrigerants which contain polluting fluorinated greenhouse gases (F-gases). To fulfil all requirements of the future today, GDTS has developed System C. Natural propane R290 is used as the refrigerant. It complies with the requirements of the F-Gas Regulation and the German federal energy efficiency ordinance (Energieeinsparverordnung, EnEV). As a result, it ensures maximum eligibility for subsidies. Particularly attractive: The GWP is only 3. This minimises the greenhouse effect in an exemplary manner. System C is therefore a particularly sustainable, future-proof investment.

System C. Advanced version.
For retail projects.

Using the example of a supermarket/food retailer, it becomes clear how perfectly networked and integrated System C is. How compact the individual units are. How energy-efficient they are. The challenges: The demand for heating, cooling and domestic hot water must be met over an area of up to 2,500 square metres. The temperature itself must be kept constant so that certain foods, such as fruit and vegetables, remain fresh for longer. The storage areas must not become too hot either. Another key requirement was To ensure 100 % compliance with the F-Gas Regulation at all times. A natural refrigerant must be used. At the same time, all subsidy programmes must be utilised.

Featuring a compact hydraulic unit and a reversible heat pump for heating and cooling, which uses eco-friendly propane as the refrigerant. It lays the best foundations for certification from the German Sustainable Building Council (DGnB, Deutsche Gesellschaft für nachhaltiges Bauen). It boosts the company's “Green Image” and ensures maximum eligibility for subsidies. To ensure a 100 % fail-safe solution, a redundancy concept is deployed, meaning an additional heat pump is connected to the circuit. This pump is engaged automatically in an emergency only. The temperature is distributed evenly using a heat distribution system, such as concrete core activation or ventilation. An intelligent control system immediately detects if rooms are too hot or too cold. Further energy benefits are also available: System C can be connected to a heat recovery system which additionally uses the waste heat from the cooling units in the supermarket to heat the store.

System C. Premium version.
For “series construction”.

Series construction is on trend. It enables office or residential buildings to be made "series-ready" in a very short space of time. With its specially developed and integrated heating and cooling system, System C is playing a key role in this endeavour. It can also be manufactured in series production. The demand for heating, cooling and domestic hot water must be met while maximising energy efficiency in large residential or office premises, e.g. on a residential building with an area of up to 3,000 m². The F-Gas Regulation had to be complied with. Accordingly, a natural refrigerant such as propane must be used.  At the same time, all requirements from the German federal energy efficiency ordinance (Energieeinsparverordnung, EnEV) must be complied with. Oil heating alone was not permitted. One key requirement when it comes to series construction is that: no valuable usable space is permitted to be lost. For this reason, the system was designed specifically for outdoor use. The heating/cooling solution also had to be easily transferable to other projects without the need for major planning work.

Featuring an extremely compact energy unit in a casing equipped with sound and thermal insulation, the hydraulics, buffer tank and domestic hot water cylinder are simply placed outside. For example, they could be mounted on the roof or behind the residential building. The reversible air-to-water heat pump is also placed outdoors on a 50 % smaller footprint – using natural propane as the refrigerant. What's more, System C can be easily planned and quickly set up, offering a high degree of prefabrication and scalability for other projects.

Extremely energy efficient and unique on the market: parallel heating and cooling with System C. This requires the use of an additional energy shifter, e.g. a brine-to-water heat pump which cares about compensation in winter as well as in summer time. The air-to-water heat pump itself is used only if temperature peaks occur. This massively increases efficiency. On office buildings, it is also worthwhile linking System C to a heat recovery system. This enables the waste heat, produced e.g. by server rooms, to be efficiently used to heat the rooms and for domestic hot water preparation.
