Abstract
A scroll compressor in which measurement of the temperature of refrigerant flowing in a path is facilitated. The scroll compressor (1) has a housing (11), a compression mechanism (15), and a pipe (71). A space (45) functioning as the path for the refrigerant is provided inside the housing (11). The compression mechanism (15) compresses the refrigerant and discharges it to the space (45) from a discharge opening (41). The pipe (71) extends from the inside of the housing (11) to the outside and has one end (71a) and the other end (71b). The one end (71a) is located at a predetermined position inthe space (45), or more specifically, at a position near the discharge opening (41), and is closed. The other end (71b) is located outside the housing (11) and is open. A measurement device (8) is inserted into the pipe (71) from the other end (71b).
Description
technical field [0001] The present invention relates to a compressor, and in particular to measuring the temperature of a refrigerant. The invention also relates to a refrigeration unit using a compressor. Background technique [0002] The compressor includes a compression mechanism that compresses the refrigerant, and a housing that accommodates the compression mechanism. A passage through which refrigerant compressed in the compression mechanism flows is provided inside the casing. [0003] In particular, in refrigeration compressors, the circulating volume of refrigerant is small, and it is necessary to drive the compression mechanism at a high compression ratio. In this compressor, the refrigerant discharged from the compression mechanism tends to become high in temperature, which may cause failure of the compression mechanism. Thus, it is necessary to measure the temperature of the discharged refrigerant and then control the operation of the compressor. [0004] The...
