The basic condition for distribution is that all heat pumps manufactured and marketed have detailed technical data, performance tables and nomograms, as well as detailed installation and functional descriptions. They can be used to select the appropriate heat pump type and to scale the probe system for heating, active or passive cooling and domestic hot water, taking into account the heat pump parameters.
Include detailed information on how to select heat pumps for functions.
This means on the part of the user and designer to use the aids to select a heat pump that can supply these functions to the building’s heat and cooling energy as efficiently as possible directly, without the installation of external elements and units. The need for various functions can be met in this form by multifunctional heat pumps with reversible circuits, built-in desuperheaters, double condensers, so there is no need for external optional elements that degrade efficiency and operational safety, increase investment costs.
Include a detailed data description for selecting the energy requirements of the heat pumps
The technical data contains detailed thermal parameters of the heat pumps, on the basis of which designers can select the heat pump with the appropriate heating capacity depending on the planned heating water temperature at maximum load and the planned lowest temperature of the liquid coming from the ground.
The capacity and type of heat pumps must always be selected for the highest load, based on the temperature of the liquid entering the lowest designed evaporator, taking into account the operating modes, DHW requirements and cooling requirements.
Provide detailed information to the system design engineers to perform the energy calculation of the building, the thermal and hydraulic sizing of the building, and then the choice of heating and cooling heat emitters. After calculating the DHW requirement and determining the heating temperature level, it should be possible to scale and select the type of heat pumps based on the planned operating mode, DHW and active or passive cooling needs.
The size of the heat pumps and the exact drawing of the connection points are required. Based on this, designers can place the heat pump in the heat center based on the dimensions and space requirements of the heat pump, they can choose the buffer and DHW storage dimensions, the ground and heating side circulation pumps. It must include the resistance of the evaporator, condenser fluid, which is the basis for the scalability of the piping system. This makes it possible to determine the parameters and type of tubes between the condenser and the buffer tank.
The installation description must include the location and size of other fittings, such as shut-off fittings, circulation pumps, deaeration points, air and sludge separators and measuring sleeves for temperature measurement. , etc.,
A performance declaration is required for each heat pump.
According to the legislation, the declaration of performance must include: Declaration identification number, product group identifier, Product type identifier / model number, product purpose, manufacturer name and address, manufacturer’s location and mailing address, registered trademark, assessment of constancy of product performance according to 305/2011 In accordance with Annex V to Regulation (EU) No. 1907/2006, the performance data, COP, EER and performance values for the product for the required temperature levels.
Document entitled “Technical parameters of heat pumps”. This is necessary for the distribution of all heat pumps in accordance with COMMISSION AUTHORIZED REGULATION (EU) No 811/2013.
The legislation contains detailed guidelines on the form and completion of this. This document contains detailed performance data for the heat pumps for the specified temperature levels, as well as data on the expected seasonal space heating efficiency of the installed heat pumps.
Factory test before trade of heat pumps
Vaporline heat pumps are marketed after performance testing in a factory test laboratory. Test documentation for all heat pumps sold for several evaporation and condensation temperature levels is archived. The tests are performed at 10min intervals after the planned temperature level has been set.
This is actually the COPcyc / integrated COP measured during the cycle time / which provides realistic data to perform the SCOP calculation. The COPcyc integrated value includes losses due to possible oscillation of the cycle, regulation of the internal cycle, and does not display the COP value measured at the peak.
Controls of Vaporline® heat pumps
We strive to satisfy the growing demand of our customers for efficiency and controllability. For this reason, all our heat pumps are equipped with a Siemens Albatros control and monitoring system, which regulates the heating flow temperature as a function of the outside temperature, measures the temperature and pressure parameters of the heat pumps and provides users with information on the operation of the system. In addition, an internet modem is built into each heat pump, ensuring system availability and controllability from all distances.
