Abstract: PURPOSE:To prompt the melting and mixing of materials by increasing the supply amount of hot water supplied to a spray nozzle for pressurized hot water feeding from a pressurized hot water supply device as the dissolving property of materials in a cup is inferior. CONSTITUTION:The above device is equipped with pressurized hot water supply devices 17 and 18 which are coupled with the spray nozzle 11 for pressurized hot water feeding and supply pressurized hot water and a flow rate adjusting device 21a which adjusts the supply amount of hot water supplied to the spray nozzle 11 for pressurized hot water feeding. When a material 13 which is inferior in dissolving property is supplied into the cup 12, the opening time of a valve 21 coupled with the spray nozzle 11 for pressurized hot water feeding is extended by the flow rate adjusting device 21a to increase the supply amount of the pressurized hot water supplied from the spray nozzle 11 for pressurized hot water feeding. Consequently, the stirring property is increased and drink can be supplied in a short period.

Abstract: PURPOSE:To avoid liquid compression in the time of cold start of a compressor simplified in its constitution by providing a communication hold, connecting a suction chamber to communicate with the inside of a closed vessel, in a fixed scroll and a valve with a built-in shape memory alloy spring halfway the communication hole. CONSTITUTION:In the time of cold start with refrigerant gas dissolved in lubricating oil 21 in the bottom part of a closed vessel 10, its low internal temperature causes a piston 25 to be pressed to the side of a shape memory alloy spring 24 by urging force of a bias spring 26 fixed by a fixing screw 27 in a fixed scroll 1, so that a suction chamber 12 communicates with the inside of the closed vessel 10 through a communication hole 22. That is, a valve 23 with a built-in spring of shape memory alloy is opened, and liquefied refrigerant, reaching the suction chamber 12, is not compressed but guided in the closed vessel 10, avoiding liquid compression. Accordingly, the improvement of reliability can be contrived while preventing a motor from burning due to an overload.

Abstract: PROBLEM TO BE SOLVED: To prevent a heating capacity from being lowered when condensation pressure is controlled to a prescribed value in a heating operation when a non- azeotrope refrigerant is used in a multi-chamber heating and cooling appliance. SOLUTION: A multi-chamber heating and cooling appliance comprises a first flow rate valve 14, a receiver tank 15, a bypass circuit 17 to which a second flow rate valve 16 is connected, an inlet pressure and temperature detecting means 21 for detecting inlet pressure and temperature, an inlet superheat degree computing means 22 for computing the degree of inlet superheat based on the detected results, a flow rate valve opening degree computing means 23 for computing the opening degrees of the first flow rate valve 14 and the second flow rate valve 16 based on the computed result, and a flow rate valve driving means 24 for driving the first flow rate valve 14 and the second flow rate valve 16 based on the opening degree. Thus, in a heating operation when a non azeotrope refrigerant is used, a heating capacity is not lowered and a desired capacity can be maintained even when condensation pressure is controlled to a prescribed value. Further, the degree of inlet superheat can be finely controlled and a cycle stability can be improved.

Abstract: PROBLEM TO BE SOLVED: To prevent the heating capacity from lowering when constant condensing pressme control is done in the heating operation using a nonazeotropic refrigerant in a multiroom type cooling/heating apparatus. SOLUTION: There are provided a bypass 17 connecting a first two way type valve 14, receiver tank 15, and second two way type valve 16, a suction pressure-temperature detective means 21 for detecting the suction pressure and temperature, a degree of superheat-of-suction calculating means 22 for calculating the degree of superheat of the suction on the basis of the result of detection, a degree of superheat-of-suction judging means 23 which judges by comparing the calculated result with a set degree of superheat, and a two way type valve-driving means 24 which drives the first two way type valve 14 and the second two way type valve 16 on the basis of the result of the judgment. As a result, in heating operation using a nonazeotropic refrigerant even the control of the operation in a manner of constant condensing pressure control does not involve a lowering in heating capacity, thus enabling the heating capacity to be secured as desired.

Abstract: PURPOSE:To sanitarily supply beverage in various cup sizes by providing a quantity storing means to store the quantity of raw materials and dilution water for each cup size, and an operating process storing means to select one cup, to fill it with the powdery raw materials and to supply pressurized hot water and dilution water. CONSTITUTION:A quantity storing means 36 is provided to store the quantity of raw materials and dilution water for each cup size, and an operating process storing means 30 is provided to store operating processes for selecting one cup from the various cup sizes, filling it with the powdery raw materials and supplying the pressurized hot water from a spray nozzle for supplying pressurized hot water and the dilution water from a nozzle for supplying hot water or water. The raw materials and the hot water are directly stirred in the cup without interposing any mixing part, and the raw materials are dissolved while being mixed with the hot water. Thus, the beverage for one cup is sanitarily supplied without fail while increasing/decreasing the quantity of hot water supplied from the nozzle for supplying hot water or the quantity of cold water supplied from the nozzle for supplying water according to the size of the cup.

Abstract: PURPOSE:To prompt the dissolving and mixing of materials by increasing the amount of hot water supplied to a spray nozzle for pressurized hot water feeding from a pressurized hot water supply device as the amount of materials supplied into a cup is larger. CONSTITUTION:The above device is equipped with pressurized hot water supply devices 17 and 18 which are coupled with the spray nozzle 11 for pressurized hot water feeding and supplies pressurized hot water and a flow rate adjusting device 21a which adjusts the amount of hot water fed to the spray nozzle 11 for pressurized hot water feeding. When a material 13 which is large in supply amount is supplied into the cup 12, the flow rate adjusting device 21a extends the opening time of a valve 21 coupled with the spray nozzle 11 for pressurized hot water feeding as compared with a material which is small in supply amount to increase the supply amount of pressurized hot water. Consequently, the dissolv ing and mixing of the materials can be prompted and the materials are securely dissolved in a short period of time.
