Detailed explanation of closed circulation cooling system debugging attention

The preparation of the closed circulation cooling system before commissioning is an important part of the debugging process, which may affect the progress of the whole debugging process. Generally, attention should be paid to the leakage detection of the closed circulation cooling system air piping system, and the leakage of the closed circulation cooling system. There are detailed regulations for the quantity, which are roughly divided into high, medium and low pressure systems. Under different pressures, the air leakage value per square meter per hour is different. The second is the visual inspection of the pipeline system. The main content of this work is to inspect the pipeline system to ensure that the various valves on the diffuser, branch pipe and main pipe are fully open to ensure that the pipeline system is in the all-pass state. Furthermore, the preparation of the closed loop cooling system commissioning equipment. Before commissioning, prepare the required test equipment including the equipment required for testing temperature, humidity, pressure, speed, and speed. The closed-loop cooling system is often prepared for different piping systems and their pre-installation work. Different, you should pay attention to this in actual work.

For the closed-circulation cooling system, when the pump and the main unit are both turned on, the end-to-end end is debugged, the valve for the end supply and return pipe that was originally turned off is turned on, and the water supply and return main pipe and the main circuit that are opened when the pipe is cleaned are turned off. On the bypass valve, see if the two-way valve is normal. If it is abnormal, check whether there is a problem with the closed circulating cooling system. Is there any electricity, or the coil of the valve has burned out? If the coil is burned without spare parts, the manual switch of the valve can be used. Forcibly open the two-way valve for commissioning.

In the actual operation of the closed circulation cooling system, the heating capacity of the closed circulation cooling system unit changes due to the difference in ambient temperature and the required temperature of the hot water supply in the refrigeration system. The heating capacity of the closed circulation cooling system unit decreases with the increase of the hot water outlet temperature and decreases with the decrease of the ambient temperature. The input power of the closed circulation cooling system unit under heating conditions increases with the increase of the outlet temperature of the hot water, and decreases with the decrease of the ambient temperature.

On the basis of the installation of the closed circulation cooling system, the corresponding closed circulation cooling system valve opening adjustment can be carried out, which is very helpful to improve the debugging speed and efficiency of the closed circulation cooling system and reduce the commissioning cost.

On the basis of this, the closed loop cooling system commissioning personnel continuously learn to continuously debug and make the closed circulation cooling system equipment achieve better running state.
