WebIn contrast to COP, COSP (Co-efficient of System Performance) is a description of the total (electrical) energy used by a heat pump in relation to the total work done (cooling or heating) by the pump. COSP can therefore be defined as the electrical power in kW used to produce 1 kW of cooling. COSP is expressed as a ratio. WebMay 1, 2014 · 1. In terms of power frequency, the core excitation current reduces for increasing f so turns are adjusted to yield capacity whatever core steel is chosen, typically 1.5T to 2T. Slightly less core mass in kW/kg with rising f for power transmission. In terms of eddy current losses , they increase with f for same power density slightly.
