A process fluid temperature calculation system includes a first temperature sensor disposed to measure an external temperature of a process fluid conduit. The process fluid temperature calculation system has a stem portion having a known thermal impedance. A second temperature sensor is spaced from the first temperature sensor by the stem portion. Measurement circuitry is coupled to the first and second temperature sensors. A microprocessor is coupled to the measurement circuitry to receive temperature information from the measurement circuitry and to provide an estimate of temperature of process fluid within the process fluid conduit using a heat flux calculation.

According to a manufacturing method of a heat flux sensor 10, the heat flux sensor 10 is sandwiched between a heater plate 206 and a cooling unit 210. The heater plate 206 is disposed on the first surface of the heat flux sensor 10, and the cooling unit 210 is disposed on the second surface of the same. A heat radiation measurement plate 205 is disposed on a surface of the heater plate 206 opposite to the surface on which the heat flux sensor 10 is disposed. According to this configuration, the temperature of the heater plate 206 is controlled in an inspection process such that the heater plate 206 is kept at an ambient temperature. This makes it possible to stabilize the temperature of the heater plate 206 in a short time.

摘要:
Usage data of an indoor climate control system for a building is obtained. To determine system susceptibility to infiltration, the infiltration parameter per unit effective leak area is determined. To determine system exposure to insolation, an insolation parameter per unit area is determined. To determine thermal isolation of the building, ambient temperature data is obtained for a time period of interest. A fit of the relevant data is performed. A large positive infiltration regression coefficient with minimal error is interpreted as indication of a significant infiltration load. Either a large positive insolation regression coefficient with minimal error for cooling or a large negative insolation regression coefficient with minimal error for heating is interpreted as indications of significant heat load due to insolation. For thermal isolation, a large positive temperature coefficient is interpreted as poor insulation or isolation against temperature-driven thermal loads.
