2Purpose of the Heat Pump

2.1Application

The brine-to-water heat pump is designed for use in existing or newly built heating systems. Brine is used as the heat carrier in the heat source system. Borehole heat exchangers, ground heat collectors or similar systems can be used as the heat source.

2.2Operating Principle

Heating

The heat generated by the sun, wind and rain is stored in the ground. This heat stored in the ground is collected at a low tem- perature by the brine circulating in the ground collector, ground coil or similar device. A circulating pump then conveys the “heated” brine to the evaporator of the heat pump. There the heat is given off to the refrigerant in the refrigerating cycle. This cools the brine so that it can once again absorb thermal energy in the brine circuit.

The refrigerant is drawn in by the electrically driven compressor, compressed and “pumped” to a higher temperature level. The electrical power needed to run the compressor is not lost in this process. Most of it is absorbed by the refrigerant.

Subsequently, the refrigerant is passed through the condenser where it transfers its heat energy to the heating water. Depend- ing on the set operating point (thermostat setting), the heating water is thus heated up to a max. of 60 °C.

Cooling

The functions of the evaporator and the liquifier are reversed in the “Cooling” operating mode.

The heating water gives up its heat to the refrigerant via the liqui- fier which is now functioning as an evaporator. The refrigerant is pumped to a higher temperature level using the compressor. Heat passes into the brine via the liquifier (evaporator in heating operation) and consequently into the ground.

3 Basic Device

The basic device consists of a ready-to-use heat pump for indoor installation, complete with sheet metal casing, control panel and integrated controller. The refrigerating cycle contains the refriger- ant R407C. R407C refrigerant is CFC-free, non-ozone depleting and non-combustible.

All components required for the operation of the heat pump are located on the control panel. An external wall temperature sensor including fixing accessories and a dirt trap are supplied with the heat pump. The power feed for the load current and the control current must be installed by the customer.

The supply lead of the brine circulating pump (to be provided by the customer) must be connected to the control panel. If re- quired, the supply lead of the brine pump is be equipped with a motor protection device.

The customer must provide both the collector and the brine cir- cuit manifold.

SI7MER, SI 11MER, SI 9MER, SI 5MER specifications

The Dimplex SI series is an impressive range of high-performance electric storage heaters designed for modern living while prioritizing energy efficiency and comfort. This line includes models SI 5MER, SI 7MER, SI 9MER, and SI 11MER, each tailored to meet various heating needs and room sizes.

One of the standout features of the Dimplex SI series is its innovative storage technology. These heaters work by storing heat during off-peak hours, when electricity costs are lower, and releasing it throughout the day. This characteristic not only helps in reducing energy bills but also provides a stable and comfortable heat output regardless of external temperature fluctuations.

The SI 5MER model is designed for smaller spaces, providing an efficient heating solution for apartments or compact rooms. The digital controls allow users to set desired temperatures easily, while the advanced thermal insulation minimizes heat loss.

Moving to the SI 7MER, this model offers a higher output suitable for slightly larger areas. It incorporates similar technology and features as the SI 5MER but with increased heat retention capacity, ensuring that spaces remain warm during colder months.

The SI 9MER takes performance up a notch, catering to medium-sized rooms. It includes a larger storage capacity and enhanced insulation, ensuring that warmth is dissipated gradually and evenly throughout the day. The integrated digital display allows for precise control, enhancing user convenience.

For those requiring even more power, the SI 11MER is the ideal option. It is perfect for larger living spaces and features advanced energy efficiency technologies. With a robust design, this model not only functions effectively but also features a sleek and modern aesthetic that can complement any interior.

All models in the Dimplex SI series are constructed with a focus on user-friendliness and safety. They are fitted with features such as overheat protection and child safety locks, ensuring peace of mind for households with children.

In summary, the Dimplex SI series—comprising the SI 5MER, SI 7MER, SI 9MER, and SI 11MER—is a versatile and efficient choice for electric heating. Each model is built with innovative technology, ensuring effective heat storage and release while maintaining energy efficiency. With a focus on safety and ease of use, these heaters are well-suited to adapt to modern lifestyle demands.
