\n\tIn our life, we believe that everyone is
\nvery familiar with refrigeration. In the central air conditioning and
\nindustrial production process cooling industry, small water-cooled chillers is
\nmore common. This unit is composed of a compressor in the fuselage, a
\nhorizontal shell and tube condenser, an evaporator, a thermal expansion valve,
\nand some related parts. Under the cooperation of these auxiliary parts, the
\noverall small water cooled chiller is compact in structure, convenient in
\noperation and control, and is popular among the public in the market.<\/span>\n<\/p>\n

\n\t<\/p>\n

\u00a0\"\"<\/p>\n

<\/span>\n<\/p>\n

\n\tFor refrigeration systems that do not have
\na high pressure reservoir and a low pressure vapor-liquid separator, the
\ncontrol of refrigerant charge is particularly important. Because the
\nrefrigeration system is a condenser and also acts as a high-pressure reservoir,
\nthe refrigerant is stored in the condenser, and the condenser is cooled. The
\nheat dissipation area is reduced and the condensing pressure is increased,
\nresulting in a decrease in cooling capacity.<\/span>\n<\/p>\n

\n\t<\/p>\n

\u00a0<\/p>\n

<\/span>\n<\/p>\n

\n\tFor the control of the refrigerant charge
\nof such small water-cooled chillers, the following methods are followed during
\nthe filling process:<\/span>\n<\/p>\n

\n\t<\/p>\n

\u00a0<\/p>\n

<\/span>\n<\/p>\n

\n\tFirst, touch the temperature of the
\ncondenser casing.<\/span>\n<\/p>\n

\n\t<\/p>\n

\u00a0<\/p>\n

<\/span>\n<\/p>\n

\n\tThe upper outlet of the condenser outlet is
\nheated above the outlet, and the outlet below the outlet is cool. (There is a
\ndescription of the high temperature exhaust of the compressor in the inside.
\nThe cooling indicates that the small water-cooled chillers is a liquid space.)<\/span>\n<\/p>\n

\n\t<\/p>\n

\u00a0<\/p>\n

<\/span>\n<\/p>\n

\n\tSecond, look at the inspiratory pressure.<\/span>\n<\/p>\n

\n\t<\/p>\n

\u00a0<\/p>\n

<\/span>\n<\/p>\n

\n\tCorresponding to the temperature of the
\nrefrigerant water in the evaporator. (That is, corresponding to the evaporation
\ntemperature.)<\/span>\n<\/p>\n

\n\t<\/p>\n

\u00a0<\/p>\n

<\/span>\n<\/p>\n

\n\tThird, look at the compressor return pipe
\ntemperature.<\/span>\n<\/p>\n

\n\t<\/p>\n

\u00a0<\/p>\n

<\/span>\n<\/p>\n

\n\tThe high-temperature unit return pipe
\nshould be cooled and dew, but it can be dew condensation to the compressor
\nreturn valve; the low-temperature unit return pipe should be frosted, but the
\nfrost can be connected to the compressor return valve. If condensation or frost
\nbuilds up on the compressor casing, liquid refrigerant will enter the
\ncrankcase, causing the compressor to run back and cause liqu<\/a>id
\nproblem.<\/span>\n<\/p>\n

\n\t<\/p>\n

\u00a0<\/p>\n

<\/span>\n<\/p>\n
