Abstract: A method comprises storing a database comprising sets of data each corresponding to a different digital document uploaded to the one or more processors and corresponding to a category tag assigned to the digital document corresponding to the set of data; receiving a natural language query; parsing the natural language query to generate one or more parsed tags; updating a second query form on the user interface with the one or more parsed tags; retrieving, using one or more generative language models, a subset of the sets of data based on each set of data of the subset corresponding to at least one assigned category tag of the one or more parsed tags; querying, using the one or more generative language models, the retrieved subset of the sets of data based on the natural language query to retrieve response data; and presenting a visual representation of the response data.

Abstract: There is provided a refrigeration system (10) comprising a compressor (12) having a suction (11) and a discharge (13), a heat rejecting heat exchanger. (14), an expansion valve (16), and a heat accepting heat exchanger (18). Preferably the system (10) comprises any one or more of: a pressure equalisation valve (4O3 42) for equalising the pressure differential between the compressor suction (11) and compressor discharge (13); a liquid valve (44), preferably a liquid solenoid valve or an electronic expansion valve, the liquid. valve (44) arranged in a flow line (24) between the heat rejecting heat exchanger (14) and the expansion valve (16); and a check valve (46), preferably a solenoid valve or an electronic expansion valve, arranged in a flow line (22) between the heat rejecting heat exchanger (14) and the compressor (12). The valves (40, 42, 44, 46) are operated in a variety of manners upon compressor shutdown and startup to avoid damage to the components of the compressor (12).
