Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] Such as Figure 1 to Figure 3 As shown, the refrigeration system of this embodiment includes a compressor 10 , a condenser 20 , an evaporator 30 , an electrical box 40 and an ejector 50 . Wherein, the electrical box 40 is arranged on the compressor 10 , and the ejector inlet 51 of the ejector 50 communicates with the outlet of the condenser 20 through a first pipeline. The first pipeline has a heat exchange matching section 60 , and the pipe wall of the heat exchange matching section 60 is attached to the bottom wall of the electrical box 40 to exchange heat for the electrical box 40 through the heat exchange matching section 60 .

[0024] Applying the refrigeration system of this embo...

Abstract

The invention provides a refrigeration system and a water chiller with the same, wherein the refrigeration system includes a compressor (10), a condenser (20), an evaporator (30) and an electrical box (40), and the electrical box (40) is set On the compressor (10), the refrigeration system also includes an ejector (50), and the ejector inlet (51) of the ejector (50) is communicated with the outlet of the condenser (20) through the first pipeline, and its characteristic That is, the first pipeline has a heat exchange matching section (60), and the pipe wall of the heat exchange matching section (60) is attached to the bottom wall and / or side wall of the electrical box (40) to pass through the heat exchange matching section (60). ) heat exchange to the electrical box (40). The technical solution of the invention can effectively solve the problem that the refrigeration system in the prior art cannot completely eliminate condensation.

Description

technical field [0001] The invention relates to the technical field of refrigeration systems, in particular to a refrigeration system and a water chiller having the same. Background technique [0002] In the prior art, when the screw water-cooled chiller works under nominal conditions (GB-T18430.1-2007 vapor compression cycle chiller), the temperature at the bottom of the electrical box of the compressor is close to the suction end temperature of the compressor (The suction temperature is about 7°C), which is generally lower than the dew point temperature of the humid air, and condensation is prone to occur. When wiring in the electrical box, the existence of the above-mentioned condensation will cause electrical safety hazards and cause corrosion to the metal parts of the compressor. Since the insulation sponge cannot be pasted in the electrical box, the existing solution to the above problem is to open a hole at the lowest end of the electrical box to discharge the conden...
