How to control system, and the vapor compression cycle to provide a vapor compression cycle

摘要

System that provides a vapor compression cycle, including the compressor (1). The first heat exchanger (2) is arranged downstream of the compressor (1), (5) is positioned downstream the first heat exchanger (2) decompressor first there. A second heat exchanger with (7) (6) is located on the downstream side of (5) a pressure reducing device of the first device accumulate heat, pressure reducing device of the second (3) heat exchange of the second I have provided on the downstream side of the vessel (6). The heat exchanger of the third (4) is positioned on the downstream side (3) pressure reducing device of the second, and connected to the compressor 1. Bypass pipe with (8) shut-off valve to bypass the heat exchanger of a third (4), at the end of the first heat exchanger of the second pressure reducing device and the second (6) and (3) It is connected between, and is connected between the compressor (1) and (4) heat exchanger of the third at the end of the second. Control device of one control shut-off valve (8), pressure reducing device of the second and (3) pressure reducing device of the first (5) at least.
