Abstract: A refrigeration cycle apparatus includes a circulation path in which a working fluid containing 1,1,2-trifluoroethylene is circulated from a compressor through a condenser, an expansion valve and an evaporator back to the compressor. The refrigeration cycle apparatus includes a composition change detection unit, a composition adjustment unit, and a control unit. The composition change detection unit detects a change of a composition of the working fluid from a steady composition thereof. The composition adjustment unit adjusts the composition of the working fluid. The control unit controls the composition adjustment unit based on a detection result obtained by the composition change detection unit.

Abstract: To provide a sprayer with high safety, specifically, a sprayer from which a component to be sprayed is incombustible and which imposes less environmental burden. A sprayer comprising a container, a propellant composition containing 1-chloro-2,3,3,3-tetrafluoropropene contained in the interior of the container, and a spray unit to spray the propellant composition to the outside of the container, wherein the propellant composition to be sprayed satisfies (1) in a predetermined combustion test, the propellant composition to be sprayed is evaluated to “have no combustibility”, and (2) the global warming potential (100 years) in accordance with Intergovernmental Panel on Climate Change (IPCC), Fifth assessment report, is less than 10, throughout the entire period over which the sprayer is used.
