For large enterprises need to use to refrigeration equipment, if the refrigeration equipment does not have a suitable installation plan, the installation will bring a lot of trouble, even if the installation is good, the later use of the equipment will be the same as a variety of small faults, therefore, the refrigeration equipment should be developed to install a good plan. Refrigeration equipment installation methods for:
1, assembly and installation of refrigeration units
Semi-sealed or hermetic compressor should be installed with an oil separator, the compressor base should be installed with a vibration-damping rubber seat, the installation should also pay attention to the need to leave a maintenance space for easy observation of the instrumentation and valve adjustment.
2, cold storage and chiller installation
According to the location of air circulation and library structure direction to choose a good location of the hanging point, the requirements of the chiller and the library board clearance should be greater than the thickness of the chiller, the chiller should be all the lifting bolts should be fastened.
3, refrigeration pipeline installation
In accordance with the compressor suction and discharge valve interface selection of copper pipe diameter, when the condenser and compressor separation of more than 3 meters should increase the diameter of the pipeline, the liquid storage tank diameter import and export diameter according to the set of samples on the labeled exhaust and liquid pipeline diameter shall prevail. Exhaust and return pipe should have a certain slope, the return pipe should be installed at the exit of the U-bend, if necessary, in the compressor return line to install filters.
4, electronic control system installation
Strictly in accordance with the drawing requirements for the production of electronic control box, and power to do no-load test, the installation of each point of contact marking the line number in order to maintain, and then the electrical components of the wires with the binding line fixed, the connection of the equipment to be laid line pipe, and fixed with a card.
5, debugging
The main debugging is the power supply voltage, refrigeration system valves open and close the situation, the compressor sound is normal, condenser and chiller operation is normal, the compressor three-phase current is smooth, etc., and then according to the cold storage of the frost and the use of the temperature parameters set and the expansion valve opening degree.
Second, the installation of refrigeration equipment to pay attention to what matters
In order to improve the safety of the installation of refrigeration equipment, the installation of refrigeration equipment need to pay attention to a number of matters, especially the large refrigeration equipment. Refrigeration equipment installation precautions are:
1, choose a suitable installation location, refrigeration equipment installation location is very important, especially when the refrigeration equipment is larger, more, need to choose a larger space and refrigeration equipment can be normal heat dissipation. If the working environment of the refrigeration equipment is poor, then it will not be able to ensure the stability of the equipment operation, and subsequently there will be some failures.
2, after the initial completion of the task of installing refrigeration equipment, the need for enterprises to seriously complete the equipment failure detection, can promptly determine whether the refrigeration equipment failure and timely processing.
3, refrigeration equipment installation, but also pay attention to a point is the installation of the pipeline, if the pipeline there is a slight or serious blockage failure, then the operation of the refrigeration equipment is bound to have a serious impact on the safety of the installation of the installation of the pipeline, and pay attention to the regular observation and testing of the refrigeration equipment running pipeline is normal.
