Abstract

PURPOSE:To measure wide-range refrigerating performance precisely and easily by providing valves before or after orifices arranged in parallel to a flow passage, and providing by-pass pipes, which have valves, before and after the orifices. CONSTITUTION:At a low pressure side between a compressor 1 and a heat exchanger 6, orifices 9 and 10 differing in diameter are provided in parallel. First, valves 11 and 12 provided before the orifices 9 and 10 are closed, and the valve 14 of a by-pass pipe 13 is opened, constituting a cycle. Then, the valve 12 before the orifice 10 for the large quantity of flow is opened, and the valve 14 of the by-pass pipe 13 is closed gradually, constituting a cycle. When the quantity of flow has a margin, the valve 14 of the by-pass pipe 13 is opened, and the valve 12 is closed; and the valve 11 of the orifice 9 for the small quantity of flow is opened, and the valve 14 is closed gradually, constituting a cycle. Thus, wide- range refrigerating performance is measured precisely and easily.
