Abstract

An additional-filling-amount management system includes a mass correlation data obtaining unit, an additional-filling-amount determination unit, and a storage unit. The mass correlation data obtaining unit obtains mass correlation data correlating with a mass of a refrigerant container from which refrigerant is supplied to a refrigeration cycle apparatus that is additionally filled with refrigerant. The additional-filling-amount determination unit determines an additional filling amount based on the mass correlation data, the additional filling amount being an amount of refrigerant, from the refrigerant container, with which the refrigeration cycle apparatus has been additionally filled. The storage unit stores apparatus information regarding the refrigeration cycle apparatus for which additional filling with refrigerant is completed and the additional filling amount that is the amount of refrigerant with which the refrigeration cycle apparatus identified with the apparatus information has been filled, in association with each other.

First claim

1 . An additional-filling-amount management system comprising:
a mass correlation data obtaining unit configured to obtain mass correlation data correlating with a mass of a refrigerant container from which refrigerant is supplied to a refrigeration cycle apparatus that is additionally filled with refrigerant; an additional-filling-amount determination unit configured to determine an additional filling amount based on the mass correlation data, the additional filling amount being an amount of refrigerant, from the refrigerant container, with which the refrigeration cycle apparatus has been additionally filled; and a storage unit that stores apparatus information regarding the refrigeration cycle apparatus for which additional filling with refrigerant is completed and the additional filling amount that is the amount of refrigerant with which the refrigeration cycle apparatus identified with the apparatus information has been filled, in association with each other.

2 . The additional-filling-amount management system according to claim 1 , wherein
the mass correlation data is a weight of the refrigerant container, and the mass correlation data obtaining unit is a scale configured to measure the weight of the refrigerant container.

3 . The additional-filling-amount management system according to claim 1 , wherein
the mass correlation data is a liquid level of refrigerant encapsulated in the refrigerant container, and the mass correlation data obtaining unit is a sensor configured to detect the liquid level of the refrigerant encapsulated in the refrigerant container.

4 . The additional-filling-amount management system according to claim 1 , wherein
the mass correlation data is a weight of the refrigerant container, and the mass correlation data obtaining unit is configured to communicate with a scale that measures the weight of the refrigerant container to receive data regarding a result of measurement from the scale.

5 . The additional-filling-amount management system according to claim 1 , wherein
the mass correlation data is a weight of the refrigerant container, and the mass correlation data obtaining unit is an image capturing unit configured to capture an image of a display portion displaying a result of measurement by a scale that measures the weight of the refrigerant container.

6 . The additional-filling-amount management system according to claim 1 , further comprising:
a display unit that displays at least one of the mass correlation data and the additional filling amount.

7 . The additional-filling-amount management system according to claim 1 , further comprising:
an advice information output unit configured to output based on the additional filling amount, advice information for an operator performing additional filling regarding an optimum filling amount of refrigerant, from the refrigerant container, with which the refrigeration cycle apparatus is to be filled.

8 . The additional-filling-amount management system according to claim 1 , further comprising:
a warning tone output unit configured to output a warning tone when the additional filling amount approaches a target value.

9 . The additional-filling-amount management system according to claim 1 , wherein
the additional-filling-amount determination unit is further configured to calculate the additional filling amount in accordance with an environmental condition.

10 . The additional-filling-amount management system according to claim 1 , wherein
the storage unit is installed at a remote site away from the refrigeration cycle apparatus.

11 . The additional-filling-amount management system according to claim 1 , further comprising:
a management apparatus that includes the storage unit; a report creation unit configured to create a report including the apparatus information and information regarding the additional filling amount corresponding to the apparatus information; and a report transmission unit configured to transmit the report to the management apparatus.

12 . The additional-filling-amount management system according to claim 2 , further comprising:
a display unit that displays at least one of the mass correlation data and the additional filling amount.

13 . The additional-filling-amount management system according to claim 2 , further comprising:
an advice information output unit configured to output based on the additional filling amount, advice information for an operator performing additional filling regarding an optimum filling amount of refrigerant, from the refrigerant container, with which the refrigeration cycle apparatus is to be filled.

14 . The additional-filling-amount management system according to claim 3 , further comprising:
a display unit that displays at least one of the mass correlation data and the additional filling amount.

15 . The additional-filling-amount management system according to claim 3 , further comprising:
an advice information output unit configured to output based on the additional filling amount, advice information for an operator performing additional filling regarding an optimum filling amount of refrigerant, from the refrigerant container, with which the refrigeration cycle apparatus is to be filled.

16 . The additional-filling-amount management system according to claim 4 , further comprising:
a display unit that displays at least one of the mass correlation data and the additional filling amount.

17 . The additional-filling-amount management system according to claim 4 , further comprising:
an advice information output unit configured to output based on the additional filling amount, advice information for an operator performing additional filling regarding an optimum filling amount of refrigerant, from the refrigerant container, with which the refrigeration cycle apparatus is to be filled.

18 . The additional-filling-amount management system according to claim 5 , further comprising:
a display unit that displays at least one of the mass correlation data and the additional filling amount.

19 . The additional-filling-amount management system according to claim 5 , further comprising:
an advice information output unit configured to output based on the additional filling amount, advice information for an operator performing additional filling regarding an optimum filling amount of refrigerant, from the refrigerant container, with which the refrigeration cycle apparatus is to be filled.
