Title:
MEASURING DEVICE FOR SPECIFIC PERFORMANCE COEFFICIENT OF MECHANICAL STEAM COMPRESSING DEVICE
Document Type and Number:
Japanese Patent JPS59104052
Kind Code:
A
Abstract:
The device is used to measure the COP of a mechanical vapor-compression system and includes a power transducer (31) to measure the power to the compressor motor (11), temperature sensors (43, 48, 46, 45) to measure respectively temperatures of the inlet (14) and outlet (13) of the compressor (12) and the inlet (17) and outlet (21) of a fluid expansion means (20), and a microprocessor (62) to store losses typical of the motor, to store the pressure versus enthalpy characteristics of the system under test, to store the temperature versus entropy characteristics of the system and to receive output signals of the temperature sensors, the microprocessor being operable to continuously determine the COP for the system as the system is operating.
