What are the Benefits of a Heat Pump? The fact that a large percentage of our energy supply is produced from fossil fuels poses serious consequences for our environment. Large quantities of pollutants such as sulphur and nitrogen oxide are released during combustion. Domestic space heating with fossil fuels contributes significantly to pollutant emissions because extensive emission control measures, such as those used in modern power plants, cannot be carried out.
Glossary Cooling capacity Sound pressure level Heat flow which is extracted from the surroundings by the evaporator of a heat pump. The heat output of the compressor is calculated from the electrical power consumption and refrigerating capacity applied. The sound pressure level measured in the surroundings is not a machine-specific quantity, but a quantity dependent on the test distance and the test location.
Heat source system Panel heating System for the extraction of heat from a heat source and the conveyance of the heat transfer medium between the heat source and the heat pump including all auxiliary equipment. Panel heating has water flowing through it and functions like a large radiator. It has the same advantages as underfloor heating. As a rule, a temperature of 25 °C to 28 °C is sufficient for the heat transfer which is mainly supplied to the rooms in the form of radiant heat.

1 1 Selection and Design of Heat Pumps 1.1 1.1.1 Design of Existing Heating Systems - Heat Pumps for the Renovation Market Heat consumption of the building to be heated In the case of existing heating systems, the heat consumption of the building to be heated must be recalculated because the existing boiler cannot serve as a gauge for the actual heat consumption. Boilers are - as a rule - overdimensioned and therefore produce a heat pump output which is too large.
Selection and Design of Heat Pumps 1.1.
1.2 same time, the costs for tapping the heat source system are lower. 1.2 1.2.1 Refer to the relevant chapters for further information on how to dimension heat source systems for brine-to-water and water-towater heat pumps. Heat Pumps for New Systems Calculating the heat consumption of the building The maximum hourly heat consumption 4his calculated according to the respective national standards. It is possible to approximately estimate the heat consumption using the living T = 0.
Selection and Design of Heat Pumps 1.3.2 1.3.4.1 Domestic hot water preparation To meet normal requirements regarding comfort, a peak domestic hot water consumption of approx. 80-100 litres per person and per day must be reckoned with based on a hot water temperature of 45 °C. In this case, allowance should be made for a heat output of 0.2 kW per person. pipes and the quality of the pipe insulation.
1.3.4.2 Experience has shown that a heat pump should be selected which cuts the heating characteristic curve for a limit temperature (bivalence point) of approx. -5 °C. ([WHUQDO WHPSHUDWXUH LQ >&@ According to the DIN 4701 T10 standard, this yields a 2 % ratio for the second heat generator (e.g. heating element) when operated as a bivalent-parallel system. Fig. 1.3 on p. 14 shows the annual characteristic curve of the external temperature in Essen, Germany.
Selection and Design of Heat Pumps 1.3.4.4 35 °C. The intersection points (limit temperature or bivalence point) of the straight line of the heat consumption of the building in relation to the outside temperature and the heat output curves of the heat pumps are approx. -5.0 °C for HP 1 and approx. -9 °C for HP 2. HP 1 would be used for the selected example. A supplementary electric heating system is used to enable yearround heating.
1.3.4.5 Heat pump output Heat source variables The heat output should be dimensioned for a limit temperature below -10 °C. This yields a heat pump output of 75 % to 95 % measured as a percentage of the total heat consumption based on the lowest external temperature. When using earth energy as the heat source (ground source), the ground heat collector or borehole heat exchanger should be dimensioned on the basis of the total heat consumption to ensure that any formation of ice thaws in the spring.
Air-to-Water Heat Pumps 2 2.2.1 Air-to-Water Heat Pumps 2.1 The Air as Heat Source Area of application of air-to-water heat pumps -25 °C... + 35 °C Availability of outside air as a heat source Unlimited Types of operation have a minimum diameter of 50 mm and should be fed into the sewer for rain water to ensure that large quantities of water can be drained off. Defrosting takes place up to 16 times daily, with up to 3 litres of condensed water being produced each time.
2.2.2 2.2.2 Air intake and air outlet via light wells If the wall openings for the air ducting on either the air intake or air outlet are positioned below ground level, it is recommended that the air circuit is routed through plastic light wells which do not impede the air flow. A cowling must be installed if the wells are made of concrete.
Air-to-Water Heat Pumps 2.2.5 2.2.5 Air-to-water heat pumps in a compact design for indoor installation In addition to the heat source, with compact air-to-water heat pumps the components for direct connection of an unmixed heating circuit are integrated. Heat pump managers Air circuit diverted at a 90° angle or on walls Overflow valve and safety components The heat pump allows for installation in a corner without additional ducts.
2.2.6 2.2.6 Air duct hose set for air-to-water heat pumps (indoor installation) Flexible hoses are offered as accessories for the air circuit for the air-to-water heat pumps LI 11TE and LI 16TE. The air duct hose set is suitable for use in rooms with low temperatures and low humidity. It contains a 5m length of thermally-insulated and sound-insulated air hose which can be used for both the air intake and the air outlet side. Air intake and air outlet can take place via a light well or a rain guard.
Air-to-Water Heat Pumps 2.3 Assembly of a standard installation set-up: Cutting lengths: Air ducts can be mounted as delivered if a standard installation set-up (see Chap. 2.3.1 on p. 22) is selected. Existing air ducts can be shortened or adapted on site using the conversion kit available as an accessory. The resulting cut edges are coated with a suitable adhesive paste (i.e. silicon) and the ends are then fitted with zinc-plated channel sections.

3.2 3.2 Ground Heat Collector The energy stored in the ground comes almost exclusively from the surface of the earth. Precipitation and solar radiation are the main sources of this energy. Thus, nothing should be built on top of collectors nor should the surface be sealed in.

3.3 3.3 Borehole Heat Exchangers When implementing a borehole heat exchanger system, a heat exchanger system is constructed in boreholes, usually with a depth of between 20m to 100m in the ground. When double U pipes are used, there is an estimated average heat source output of approx. 50 W per drilling metre of loop. However, exact dimensioning depends on the respective geological and hydrogeological conditions, which are generally unknown by the heating technician.
Brine-to-Water Heat Pump 3.3.2 3.3.3 Preparation of boreholes The clearance between the heat exchangers should be at least 6 m so that reciprocal interference is kept to a minimum and regeneration is guaranteed in the summer. If several heat exchangers are required, these should not be laid out parallel to the direction of ground water flow, but transverse to it. (see Fig. 3.7 on p. 79).

Heat Pump Manager 7.1 7 Heat Pump Manager The heat pump manager is essential for operation of air-to-water, brine-to-water and water-to-water heat pumps. It regulates a bivalent, monovalent or mono energy heating system and monitors the safety components in the refrigerating circuit. The heat pump manager is either installed in the heat pump casing or is delivered with the heat pump as a wall-mounted controller.

Integration of the Heat Pump in the Heating System 8.3.1 8 Integration of the Heat Pump in the Heating System 8.1 Hydraulic Requirements During the hydraulic integration of a heat pump it must be kept in mind that the heat pump only has to generate the actually required temperature level to increase efficiency. The objective is to feed the temperature level generated by the heat pump directly (unmixed) into the heating system.
8.3.2 8.3.2 Temperature spread in relation to the heat source temperature The heat output of the heat pump depends on the heat source temperature. This is especially the case, when the outside air is used as the heat source. The maximum temperature spread in relation to the heat source temperature can be found in the following tables. Air-to-water heat pump Heat source temperature From To Max.
Integration of the Heat Pump in the Heating System 8.3.5 8.4.1 Dual differential pressureless manifold In a heat pump, the dual differential pressureless manifold is a useful alternative for the buffer tank connected in parallel, since it fulfils the same function without compromising when it comes to efficiency. The hydraulic isolation is realised using two differential pressureless manifolds with a check valve each (see Fig. 8.28 on p. 192).
8.4.2 NOTE Immersion heater The use of the KPV 25 compact manifold with overflow valve is recommended for heating systems with panel heating and a heating Buffer tank water flow rate up to max. 1.3 m3/h.
Integration of the Heat Pump in the Heating System 8.4.3 NOTE 8QPL[HG KHDWLQJ FLUFXLW 0L[HG KHDWLQJ FLUFXLW The use of the DDV 32 compact manifold is recommended for heat pumps with a heating water flow rate up to max. 2.5 m3/h.
8.5 8.5 Buffer Tank A buffer tank connected in series is recommended for heat pump heating systems to ensure the minimum runtime of the heat pump of 6 minutes for all operating statuses. Buffer tanks connected in series are operated on the temperature level required by the heating system. They are not used for bridging shut-off times (see Chap. 8.5.3 on p. 180). Air-to-water heat pumps with defrosting by reverse circulation extract the energy required for defrosting from the heating system.

Integration of the Heat Pump in the Heating System 8.5.5 Check valve If a water circuit contains more than one circulating pump, each pump unit must be equipped with a check valve to prevent mixing from other heating circuits. It should be ensured that check valves close tightly and are noiseless during flow through. 8.6 NOTE With a mixer in the underfloor heating circuit or in bivalent-renewable operating mode, the mixer is closed when the temperatures are too high.
8.8 8.8 Contaminants in the Heating System When installing a heat pump in a new or existing heating system, the system should be flushed to remove deposits and suspended matter. These types of contaminants can reduce the heat transfer of the radiators, impede the flow or collect in the condenser of the heat pump. In extreme cases, they can cause the heat pump to switch off automatically. Oxidation products (rust) can form if oxygen enters the heating water.
Integration of the Heat Pump in the Heating System 8.9.3 8.11 Renewable heat sources The heat pump manager has a separate operating mode for the integration of renewable heat sources such as solid fuel boilers or thermal solar energy systems. The “Bivalent-renewable” operating mode can be chosen during the preconfiguration.
8.12 8.12 Hydraulic Integration The heating system control is nearly identical for air-to-water, brine-to-water and water-to-water heat pumps, however, the hydraulics for the integration of the heat source are different. The integration diagrams shown on the following pages show standard solutions for the most common applications. The heat pump manager controls the individual components.

Investment and Operating Costs 9.1 9 Investment and Operating Costs The overall costs of a heating system consist of three parts: instalments. To carry out a full costing (including interest), the investments are broken down into annual instalments on the basis of the interest rate and the operating period. The most frequently used calculation method is the annuity method which assumes the heat demand to remain constant.

One system for all types of heat sources Air-to-water heat pumps utilise the outside air as their energy source. Even at temperatures of up to -25°C, heat pumps can still extract heating energy from the outside air. Dimplex heat pumps offer you three different future-proof heat sources, free of charge: outside air, ground or ground water. Brine-to-water heat pumps extract heat from the ground, year-round via ground heat collectors or borehole heat exchangers with a high heating capacity.
