Installation of auxiliary equipment of refrigeration system in clean room


Auxiliary equipment is the evaporator, condenser and other components in the piston compression refrigeration system. In order to ensure that the installed system is in a clean state, the auxiliary equipment must be blown before installation; the evaporator should be filled with water in the water tank before installation. In the test, no leakage is considered qualified. The evaporator group is tested for tightness with compressed air or nitrogen with a pressure of 1.2MPa. The pressure is stabilized for 12H without leakage. It is qualified with compressed air with a pressure of 0.6MPa. until. During the layout of vertical evaporators, three or less evaporators can be arranged on the reliable wall. When there are more than three evaporators, they can be connected in one piece or installed in groups to facilitate operation and maintenance; Filled with water for 8-12 hours, it is qualified for no leakage; when installing, first hoist the water tank to the pre-made upper cushion with a thermal insulation layer, and then put the evaporator tube group into the box. The evaporator tube group should be Vertical and slightly inclined to the oil discharge end, the spacing of each tube group should be equal, after the evaporator tube group is assembled, and after passing the air tightness test, the water tank can be insulated; the float valve should be cleaned and adjusted before installation, and added Good refrigeration oil, the relative elevation of the float valve and the evaporator is determined by the evaporation temperature; after all installations are completed, the cold water tank is insulated after passing the test.


Horizontal evaporators are generally installed on indoor concrete foundations, connected to the foundation with anchor bolts. After leveling, tighten the anchor bolts, and do the air pressure test first and then the water pressure test; the float valve should be cleaned and adjusted The relative elevation of the float valve and the evaporator is determined by the evaporation temperature; the levelness requirements of the horizontal evaporator are the same as those of the horizontal condenser, which can be measured directly on the cylinder with a leveling instrument.
Before running the evaporator, start the agitator, slowly open the evaporator return valve, and then open the liquid supply valve accordingly to adjust the liquid supply; when the chilled water in the evaporator meets the production requirements, open the chilled water inlet The outlet valve, start the chilled water pump; when the evaporator is working normally, the surface of each evaporating pipe should be covered with uniform dry frost, and there should be no phenomenon of no frost or uneven frost; the oil should be discharged once every half month, and it should be closed when the oil is discharged. Inlet valve and outlet valve. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean rooms and clean rooms.














Accumulators are used in refrigeration equipment to store and adjust the circulating volume of liquid refrigerant to ensure normal liquid supply and reliable operation of the compressor. According to different functions, the accumulators can be divided into high-pressure accumulators and low-pressure accumulators. The liquid reservoir has roughly the same structure; check whether the plane position, elevation, surface flatness of the equipment foundation, and the size of the pre-embedded anchor bolts meet the equipment and design requirements, and clean up the sundries in the foundation hole; After it is in place, it should be leveled and aligned to determine the levelness of the liquid storage tank; the anchor bolts should be filled with concrete, and after the concrete strength reaches 75%, it should be leveled and the anchor bolts should be tightened; The inlet and outlet pipes must not be installed incorrectly.


Before the separator is installed, the direction and position of the nozzle, the position of the anchor bolt hole and the foundation should be checked, and it should meet the design requirements; the air tightness test and unit purging should be carried out, and the air tightness test pressure should meet the Design and equipment technical documents stipulate that the installation level deviation of horizontal equipment and the vertical deviation of vertical equipment should not be greater than 1/1000; Anti-corrosion treatment should be carried out in advance, and the thickness should not be less than the thickness of the thermal insulation layer; the elevation of the liquid inlet of the washing oil separator should be lower than that of the liquid outlet of the condenser; the direction and position of the inlet and outlet of the pipeline connected to the equipment should be Meet the technological process and design requirements.
