Heat pumps with electrically driven compressors - Testing and requirements for marking of domestic hot water units

This European Standard specifies methods for testing and reporting of the rating and it specifies requirements for marking of air/water, brine/water, water/water and direct exchange/water heat pumps with electrically driven compressors connected to or including a domestic hot water storage tank. When these units are used for space heating, then EN 14511 (all parts) applies.
In case of air-to-water heat pumps, this European Standard comprises only factory-made units which can be ducted on the airside.
This European Standard comprises only the testing procedure for the domestic hot water production of the heat pump system.
NOTE   Testing procedures for simultaneous operation for domestic hot water production and space heating are not treated in this standard. Simultaneous means that domestic hot water production and space heating generation occur at the same time and may interact.
In the case of units consisting of several parts, the standard applies only to those designed and supplied as a complete package.
This European Standard does not include any requirement about the quality of water.

Wärmepumpen mit elektrisch angetriebenen Verdichtern - Prüfungen und Anforderungen an die Kennzeichnung von Geräten zum Erwärmen von Brauchwarmwasser This European Standard was approved by CEN on 3 December 2010.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.

This document has been prepared by the working group CEN/TC 113/WG 10 "Heat pumps and air conditioners". This standard was submitted to enquiry under the reference prEN 255-3 which has been changed before Formal Vote to FprEN 16147. This European Standard references the document TREN D1 D(2002) M/324 for information on “Water-Heaters, Hot Water Storage Appliances and Water Heating Systems”.
Testing procedures for simultaneous operation for domestic hot water production and space heating are not treated in this standard. In this standard the basis of the measurements are the daily EU-Reference-Tapping-Cycles defined in the mandate M/324. Presently there is no standard fixed for daily cycles for the space heating mode. The following technical and general modifications have been introduced during the revision: − The new COPDHW is smaller than the former COPt of EN 255-3, since heat losses of the hot water storage tank are not considered in the calculation of the COPDHW, whereas the former standard EN 255-3 accounted these losses. − In EN 16147, five different daily tapping profiles (S, M, L, XL, and XXL) for different storage tank sizes can be selected in order to determine the coefficient of performance. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

5 General test requirements 5.1 Test apparatus and uncertainties The test apparatus shall be designed in such a way that all requirements for adjustment of set values, stability criteria and uncertainties of measurement according to this European Standard can be fulfilled. Water systems or other heat transfer liquid systems shall be sufficiently free of entrained gas as to ensure that the measured results are not significantly influenced. The inlet and outlet temperatures of the domestic water are measured in the centre of the flow and as close as possible to the appliance. The response time of the temperature sensor and the sampling interval have to be chosen to maintain the uncertainties in Table 1. Ducted air systems shall be sufficiently airtight to ensure that the measured results are not significantly influenced by exchange of air with the surroundings. The uncertainties of measurement shall not exceed the values specified in Table 1, the permissible deviations shall not exceed the values specified in Table 2. In addition the maximal permissible deviation of thermal energy for the complete tapping cycle shall be less than 5 %.

5.2 Test room for the outdoor heat exchanger of air source heat pumps The size of the test room shall be selected to avoid any resistance to air flow at the air inlet and air outlet orifices of the test object. The air flow through the room shall not be capable of initiating any short circuit between the two orifices, and therefore the velocity of air flow at these two locations shall not exceed 1,5 m/s when the test object is switched off. The air velocity in the room shall also not be higher than the mean velocity through the unit inlet. Unless otherwise stated by the manufacturer, the air inlet and air outlet orifices shall not be less than 1 m from the surfaces of the test room; this also applies to any measuring ducts. Any direct heat radiation (e.g. solar radiation) onto heating units in the test room onto the heat pump or onto the temperature measuring points shall be avoided. 5.3 Setting the external static pressure difference on the air side for heat pumps with duct connection 5.3.1 All units The test conditions are given in Table 4 and Table 5. If liquid heat transfer media other than water are used, the specific heat capacity and density of such heat transfer media shall be determined and taken into consideration in the evaluation. Table 2 states permissible deviations of the measured values from the test conditions. 5.3.2 Non ducted units For non ducted units, the adjustable settings such as louvers and fan speed shall be set according to the manufacturer instruction.

The accessories provided by option (for example heating element) are not included in the test. Temperature and pressure measuring points shall be arranged in order to obtain significant mean values. Set points for internal control equipment of the unit such as thermostats, pressure switches or mixing valves should be set to the values stated by the manufacturer. SIST EN 16147:2011

The appliance shall be installed and adjusted in the initial state conditions and in the initial adjustment conditions defined in 5.1. 6.2 Basic principles, scope of the tests The tests consist of the following six principal stages (see Figure 1, Key 1): A heating up period (see 6.3) B determination of standby power input (see 6.4) C determination of the energy consumption and the coefficient of performance for heating domestic water by using the reference tapping cycles (see 6.5).
