PROBLEM TO BE SOLVED: To provide a technology to enable accurate measurement of individual calorie consumption of each water source heat pump unit in an individual air conditioning system using the water source heat pump unit.SOLUTION: The individual calorie consumption measuring method measures the individual calorie consumption of a water source heat pump unit 3 based on a heat source water flow Qw supplied to a heat exchange coil 62 and a heat source water temperature difference ΔTHw before and after heat exchange with a heat medium. An inlet side temperature sensor and an outlet side temperature sensor are installed at an inlet side branch pipe 21 and an outlet branch pipe 22 respectively. Using an inlet side temperature waveform and outlet side temperature waveform obtained from each temperature sensor during no load period when the compressor 50 of the water source heat pump unit 3 is under suspension, synthetic instrument difference specific processing is performed to determine the synthetic instrument difference ΔIE between the two temperature sensors by obtaining at least one of the maximum value and minimum value thereof. This processing is implemented prior to processing for a heat source water temperature difference.

PROBLEM TO BE SOLVED: To provide a duct inside airflow meter and a measurement method capable of accurately measuring an airflow inside a duct even when elongation of a sensor member occurs.SOLUTION: A duct inside airflow meter comprises: a linear or planar sensor member 20 disposed across the inside of a duct 1; a take-up motor 22 that adds a tension to the sensor member 20; an encoder 30 that detects a rotation position of the take-up motor 22; and a calculation section 32 that detects the tension added to the sensor member 20. In a windless state, a predetermined tension is added to the sensor member 20 by the take-up motor 22, and the rotation position of the take-up motor at this time is detected by the encoder 30. The rotation position is set as a reference position, and in an air blowing state, the take-up motor 22 is controlled so that the rotation position of the take-up motor detected by the encoder 30 is held at the reference position. The tension added to the sensor member 20 at this time is detected, and on the basis of the detected tension, an airflow inside of the duct 1 is measured.

PROBLEM TO BE SOLVED: To improve measurement accuracy when detecting a change in the temperature of a fluid within a pipe by two temperature sensors and measuring the flow of the fluid flowing through the pipe on the basis of a time difference on that occasion, by performing the determination of the time difference more easily and more accurately as compared to conventional ones. SOLUTION: Temperature waveforms obtained by measuring a change in the temperature of the fluid within the pipe 1 by a first temperature sensor 11 on the upstream side and a second temperature sensor 12 on the downstream side are subjected to moving average processing. A temperature gradient waveform is then determined for each. A positive value of each temperature gradient waveform is divided by the maximum value of the temperature gradient waveform, while a negative value is divided by the minimum value of the temperature gradient waveform. Either one of the resultant corrected temperature gradient waveforms is moved in the time direction. The time for the movement when the area surrounded by the two waveforms is minimized is determined to be the time difference for determining the flow rate of the fluid. COPYRIGHT: (C)2011,JPO&INPIT
