BAM Test method for heat pumps and Air conditioners
- The Federal Institute for Materials Research and Testing (BAM) has developed a load-based test method (compensation method) to determine the energy efficency of heat pumps and air conditioners. The method allows for testing with unfixed compressor speed and active control of the unit. Thus, at low part loads the unit under test is allowed to cycle on-off, when the frequency of the compressor drops below its minimum threshold. Therefore, the associated efficiency losses are directly measured and correction calculations as for the current steady state tests become obsolete. In addition, the testing can be performed without the support of the manufacturer by market surveillance authorities, for instance, since no frequency and expansion valve settings are required. To prove that the compensation method is repeatable and reproducible three round robin tests have been organised by BAM.
