<p><P>PROBLEM TO BE SOLVED: To easily know fuel consumption in response to actual conditions in a required partial load operation. <P>SOLUTION: A test outdoor unit is disposed in an outdoor-side test room and a test indoor unit is disposed in an indoor-side test room, temperature and humidity conditions in the outdoor-side test room and the indoor-side test room are respectively adjusted to keep test conditions, an air-conditioning target temperature of the test indoor unit is set by a remote control device 29, the temperature difference between a temperature of sucked air measured by a temperature sensor 24 and the air-conditioning target temperature is applied as control index, an air-conditioning capacity is calculated by performing an automatic control operation to eliminate the temperature difference, and the fuel consumptions of the test indoor unit and the test outdoor unit in a state that the operation is performed with stable air-conditioning capacity for a set time, are measured and integrated. In a capacity test under partial load, a resistance value from a variable resistor 33 having specific correlative relationship segmentalized by 1/10°C or more between the temperature and the resistance value, is used for the temperature sensor 24 to artificially adjust the temperature difference as the control index. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
