摘要： A refrigerant recovery system includes a cylinder, a first detection unit, and a control unit. The cylinder accommodate a refrigerant filling a refrigeration cycle apparatus. The first detection unit detects a predetermined physical quantity in order to calculate a composition of the refrigerant accommodated in the cylinder. The control unit acquires a result of detection by the first detection unit and outputs the result as a first detection result.

摘要： A maintenance assistance system outputs a facility maintenance plan for a facility device. The maintenance assistance system includes: an acquisition unit that obtains operation data of the facility device; a memory that stores maintenance cost data corresponding to a content and scheduled time for maintenance of the facility device; a maintenance planning unit that uses the operation data of the facility device to plan a content and scheduled time of maintenance that will become necessary after the operation data is obtained; a maintenance cost calculator that uses the maintenance cost data stored in the memory to calculate a maintenance cost corresponding to the planned content and scheduled time of the maintenance; and a maintenance plan output unit that generates a facility maintenance plan including information in which the content and the scheduled time of the maintenance and the maintenance cost are associated with each other, and outputs the facility maintenance plan.

摘要： In an air conditioner, during an operation, a gas-liquid two-phase non-azeotropic mixture refrigerant enters a receiver and accumulates in the receiver in a state where a gas phase and a liquid phase are separated. For example, when the non-azeotropic mixture refrigerant includes two components, i.e., a high-boiling refrigerant and a low-boiling refrigerant, the controller may estimate the ratio (composition ratio) between the low-boiling refrigerant and the high-boiling refrigerant in each of the gas phase and the liquid phase based on the temperature and the pressure of the non-azeotropic mixture refrigerant in the receiver. Thus, the controller may estimate the composition ratio of the liquid-phase non-azeotropic mixture refrigerant flowing out of the receiver as the composition ratio of the non-azeotropic mixture refrigerant circulating in the refrigerant circuit.

摘要： A refrigeration cycle apparatus includes a first refrigerant circuit and a second refrigerant circuit so as to improve the efficiency of operations. A first refrigerant circuit using a first refrigerant having a pressure of 1.2 MPa or less at 30° C. and a second refrigerant circuit using a second refrigerant having a pressure of 1.5 MPa or more at 30° C. are provided, and a dual cycle operation in which the first refrigerant circuit and the second refrigerant circuit are simultaneously operated to exchange heat between the first refrigerant and the second refrigerant and a single cycle operation in which the first refrigerant circuit is operated without operating the second refrigerant circuit to perform a cooling operation or heating operation are enabled in a switchable manner.

摘要： A refrigeration cycle apparatus efficiently performs a cooling operation and a heating operation using a low-pressure refrigerant and a high-pressure refrigerant. A refrigeration cycle apparatus performs a heating operation by performing a two-stage refrigeration cycle, the two-stage refrigeration cycle including a use-side refrigeration cycle using a first refrigerant having 1 MPa or less at 30° C. and a heat-source-side refrigeration cycle using a second refrigerant having 1.5 MPa or Imre at 30° C., and performs a cooling operation by performing a single-stage refrigeration cycle using the first refrigerant.
