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 direct-expansion heat pumps is as follows:

• Testing the capacity and efficiency at full-load and part-load operation, in accordance with prEN 15189 and EHPA Testing Regulations.
• Operation of control and safety functions etc., in accordance with prEN 15189 and EHPA test regulations.
• Testing and inspection for EHPA (European Heat Pump Organization) Quality Label certification.
• 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.
