Abstract: PROBLEM TO BE SOLVED: To provide a commodity carry-out device of a vending machine capable of dispensing with wiring in a commodity rack and a commodity conveyer to reduce the manufacturing cost and improved reliability. SOLUTION: A sold-out flag 6 mounted on the commodity conveyer 3 is displaced according to whether the commodity is out or not. After the commodity conveyer 3 returns to the standby position, the sold-out of the commodity is detected by a sold-out detecting sensor 7, whereby wiring is not required in the commodity rack 1 and the commodity conveyer 3 to reduce the manufacturing cost and improve reliability.

Abstract: PROBLEM TO BE SOLVED: To provide a measuring instrument for air conditioner which can solve the problem raised by the conventional constitution that the operating characteristics of the other equipment than a sensor installed to equipment cannot be measured at the time of measuring the operating data of an air conditioner and, accordingly, the diagnostic accuracy of the air conditioner becomes lower. SOLUTION: Since a numerical stitching means 15 switches in advance the used sensor to the already existing sensor of the air conditioner or the accessory sensor of an interface unit IFU1 equipped with the sensor, it becomes unnecessary to attach the accessory sensor to the interface unit IFU1 ad the working man-hour of a service man can be reduced when the already existing sensor is installed to the air conditioner. In addition, since the operating data of the air conditioner can be measured by using a communication line, it becomes unnecessary to install a first measuring instrument CNT1 outdoors and the operating data of the air conditioner can be measured accurately without being influenced by the outdoor air temperature and the installed morphology of the instrument CNT1.

Abstract: PROBLEM TO BE SOLVED: To improve the cooling startability by setting each valve in freezing cycles on utilization side and performing the operation of a refrigerant carrying pump, and besides, setting each valve in freezing cycles on heat source side and performing the operation of a compressor, at start of cooling operation, and fully opening a bypass valve after passage of a specified time. SOLUTION: After start of cooling operation, the setting of each valve in freezing cycles on heat source side is performed, and next the setting of each valve in freezing cycles on utilization side is performed. That is, the first controller Cnt1 opens the first flow control valve RV1 into specified aperture, and fully opens the second flow control valve RV2 and a bypass flow valve RV, and opens the second two-way valve SV2. In addition, it turns on a refrigerant pump PM, and turns on a compressor, and performs the detection of the passage time after start of operation. Then, a liquid refrigerant can be carried to indoor units 12a and 12b, and it can shift smoothly to normal cooling mode, without falling in liquid shortage or gas shortage operation, by fully closing the bypass valve RV, in case that the operation passage time comes to the specified time or over.

Abstract: PROBLEM TO BE SOLVED: To control a plurality of refrigerant pumps installed at a refrigerant transporting device in such a way that a frequency of operation of each of the pumps may become uniform, prevent a stopping in operation caused by trouble and further to prevent a continuous operation from being carried out in an air conditioner which is comprised of a plurality of indoor and outdoor devices and the refrigerant transporting device. SOLUTION: This air conditioner is provided with a control device 16 which is comprised of a current sensing means 13 for sensing an input current for refrigerant pumps 8a, 8b, 8c and an accumulating means 14 for accumulating operation times, thereby the operation times when an input current more than a predetermined value are calculated. As the time reaches a predetermined calculated time, the refrigerant pump being operated at present is stopped and the refrigerant pump being stopped is energized. An operating frequency of each of a plurality of refrigerant pumps 8a, 8b and 8c is made uniform by changing-over the refrigerant pumps, a stopped state of operation of each of the pumps caused by trouble is prevented and then a continuous operation of the pumps can be carried out without prohibiting a comfortable feeling of an indoor environment.
