Testing of exhaust air heat pumps

 

SP’s testing ranges from comprehensive testing of performance aspects such as heat pump capacity, efficiency, sound power level and correct operation of control and ancillary functions, to less comprehensive but more specialised testing such as measuring performance at a specified operating point.  

A list of the most common tests that we perform for exhaust air heat pumps is as follows:   

• Measurement of capacity and efficiency at full-load and part-load operation, and checking correct operation of functions, normally in accordance with EN 14511, CEN/TS 14825 and SP Method 2800.
• Testing of capacity and efficiency for production of domestic hot water in accordance with EN 255-3, FprEN 16147 and/or LOT 2 Annex IV on Eco-design Implementing Measures for Dedicated Water Heaters.
• Testing for air leakage and air flow capacity.
• Testing defrosting and safety functions etc. in accordance with EN 14511-4.
• SP can perform visual and technical inspection of heat pumps.  We also inspect Swedish-language user instructions and care and maintenance instructions.
• Sound power measurements in accordance with ISO 3747 and EN 12102.
• In addition, SP can also measure most other functions and parameters as required by our customers, such as pressures in refrigerant systems, hot gas temperatures and testing and inspection in accordance with other national and international certification systems as required.
