Abstract

The invention discloses a water-cooled screw type cold water unit which comprises a water-cooled unit shell (1), an axial flow fan (2), a motor (3), a fin type heat exchanger (4), an electric controlcabinet (5), an expansion valve (6), a semi-closed screw type compressor (7), a gas-liquid separator (8), a low-pressure gas return pipe (9), a high-pressure exhaust pipe (10), a shell-and-tube heat exchanger (11), a chilled water inlet (12) and a chilled water outlet (13), wherein the axial flow fan (2) is arranged at the top of the water cooling unit shell (1), the axial flow fan (2) is arrangedat the top of the water cooling unit shell (1), the axial flow fan (2) is connected with the motor (3), the fin type heat exchanger (4) is arranged at the upper part of the shell of a water cooling unit, one side of the lower part of the water cooling unit shell (1) is provided with the electric control cabinet (5), and one side of the electric control cabinet (5) is provided with the semi-closedscrew type compressor (7), the gas-liquid separator (8) and the shell-and-tube heat exchanger (11), and the two ends of the semi-closed screw type compressor are connected with the finned heat exchanger (4) and the shell-and-tube heat exchanger (11) through the high-pressure exhaust pipe (10) and the low-pressure air return pipe (9) respectively. The water-cooled screw type cold water unit is adopted, so that the structure design is reasonable.

Description

technical field [0001] The invention relates to the technical field of chillers, in particular to a water-cooled screw chiller. Background technique [0002] Water-cooled screw chillers can be widely used in shopping malls, hotels, schools, banks, halls, hospitals and other places. At present, the existing water-cooled screw chillers have unreasonable structural design. Therefore, urgently need those skilled in the art to develop a kind of new water-cooled screw chiller. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a water-cooled screw chiller. [0004] The technical solution adopted to solve the technical problems is: a water-cooled screw chiller, which includes a water-cooled unit shell, an axial fan, a motor, a finned heat exchanger, an electric control cabinet, an expansion valve, a semi-hermetic screw chiller Compressor, gas-liquid separator, low-pressure air return...
