Clean Air Conditioning Water Cooled Chiller
Clean room water-cooled chiller is a central air-conditioning refrigeration host product that uses water as the cooling medium. Compared with the air-cooled unit with the same cooling capacity, because its condenser and evaporator are made of special high-efficiency heat transfer tubes, Therefore, the structure is compact, the volume is small, the efficiency is high, and because there is no condensing fan, the noise is low. The unit should have a dedicated computer room, and measures should be taken to remove the heat generated during the operation of the unit from the computer room, and the ventilation rate should be able to maintain the requirement that the room temperature does not exceed 40 °C; the unit should be installed on a non-deformed rigid base or concrete foundation. The surface should be flat and can bear the weight of the unit during operation. The size of the machine clean room modular should be able to ensure a space of 1.5m around the unit and more than 1m above the unit, so as to facilitate the maintenance of the unit. At the same time, pipes and line pipes should not be laid above the compressor.
The installation and insulation of the water pipeline of the air-conditioning system should be designed and guided by professional designers, and the corresponding regulations of the HVAC installation specification should be implemented; the water inlet and outlet pipelines should be connected according to the requirements of the marking on the unit, and the condenser water pipe should be connected downward and upward. The side of the evaporator refrigerant pipe is the side of the chilled water inlet; the water system must be equipped with a water pump with appropriate flow and head to ensure normal water supply to the unit. In addition, the support should be provided to avoid the unit being stressed. The welding work during installation should avoid damage to the unit; the water filter must be installed before the water inlet pipeline of the unit, and a filter screen of 16 mesh or more should be selected; the system water pipeline is flushed and cleaned. Insulation should be carried out before connecting with the unit to avoid damage to the unit; the flow switch should be installed vertically on the outlet pipe; there should be at least 5 times the diameter of the pipe on both sides of the flow switch; In order to prevent the flow switch from shaking, all the gas in the water system should be discharged, and the flow switch should be adjusted so that it is in a separated state when the water flow is lower than the minimum flow. When the water flow meets the requirements, the water flow switch should be kept closed. . Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean rooms and clean workshops.
The cooling water pipeline must be installed with anti-vibration soft connector, thermometer, pressure gauge, drain valve, stop valve, water filter, check valve, etc., and then connected with the cooling tower inlet and outlet water pipeline; the water supply pipeline should be as far as possible Short, the specifications of the pipeline should be determined according to the effective head of the pump, pipeline flow and flow rate; the direction of the water outlet of the condenser can be changed according to the user's requirements, the correct position of the partition plate needs to be confirmed, and a new rubber sealing ring should be used. The temperature and flow measurement devices need to be rearranged; when disassembling and assembling the end cover of the water chamber, the fixing bolts must be carried out in a certain order. The expansion tank should be installed 1-1.5m above the highest point of the air-conditioning system. The capacity of the water tank is about 1/10 of the water volume of the entire system. A floor-standing expansion tank can also be used; the water pipe should try to avoid changes in the vertical direction. Install a manual or automatic exhaust valve between the high place and the expansion tank; the chilled water pipeline and expansion tank should be insulated, and the valve joint should be reserved for maintenance operations; after the pipeline has undergone an air-tightness test, the insulation layer , to avoid heat transfer and condensation, the insulation layer should be covered with a moisture-proof seal.
