“…In addition, its power consumption and performance (refrigerating capacity) were tested using a calorimeter as in Figure 15. The rotation speed of the motor inside the compressor was measured using a vibration sensor, and the refrigerating capacity was measured according to the ASHRAE L.B.P test conditions [24][25][26].…”

This article describes a rotor making technology for the production of high-efficiency single-phase induction motors (SPIMs) to be used in refrigerator compressors. Rotors can have different aluminum fill factors according to the fabrication method. In order to examine the association between the fill factor and the efficiency of the rotor, we analyzed the distribution of magnetic flux density using the finite element method (FEM). Next, we made prototype rotors by conventional casting methods and by the proposed casting method and compared their fill factors. In addition, SPIMs were made using the rotors, and their efficiencies were measured using a dynamometer. Moreover, the SPIMs were put to use in a compressor, for testing, and for each SPIM the refrigerating capacity of the compressor was measured with a calorimeter. Based on the results of the FEM analysis of the magnetic flux density and the experiments, the reliability and validity of the proposed method were proven.

“…In practice, there are two approaches available for minimizing the error. One is adopting multiple temperature sensors in a grid to find a mean temperature [15], and the other is using a temperature equalizer to average the fluid temperature at the temperature measurement point [21]. The latter is used in this design and is illustrated in detail in Fig.…”

“…Clearly, the balanced calorimeter or the series calorimeter [15] can remove the need for measuring fluid properties and associated measurement errors. They need to employ a resistive heater to replicate the load test and to operate along with the machine in the sequence of time (balanced) or space (series).…”

This paper introduces a simple core loss calculation method for output filter inductor in pulse width modulation (PWM) DC-AC inverter. Amorphous C-core (AMCC-320) is used to analyze the core loss. In order to measure core loss of the output filter inductor and validate the proposed method, a single-phase half-bridge inverter and a calorimeter are used. By changing switching frequency and modulation index (MI) of the inverter, core loss of the AMCC-320 is measured with the lab-made calorimeter and the results are compared with calculated core loss. The proposed method can be easily extended to other core loss calculation of various converters.
