Reasonably adjust the intermediate pressure and intermediate temperature of the chiller. The intermediate pressure and intermediate temperature are related to the condensation temperature, the evaporation temperature and the volume ratio of the high and low pressure machines. It is worth noting that in actual operation, the normal liquid level of the intercooler must be maintained. This is not only conducive to reducing the exhaust temperature of the high-pressure machine and preventing the formation of carbon deposits, but also conducive to reducing the temperature of the refrigerant liquid before the throttle valve, increasing the unit cooling capacity and improving the cooling coefficient.
The condensing pressure of the refrigerator should be adapted to the condensing temperature. If the condensing pressure is too high, check whether the relevant valves of the high-pressure system are opened, discharge air and oil, increase the cooling water volume and cooling air volume, reduce the cooling water temperature, reduce the heat load, and configure the condenser reasonably.
The evaporation pressure should be adapted to the evaporation temperature. In air conditioning systems and medium temperature and medium pressure refrigeration systems, the evaporative pressure is generally higher than atmospheric pressure, which is beneficial to prevent air from entering the refrigeration system. For places that require low temperature, multi-stage compression refrigerators, cryogenic refrigerators or low-temperature refrigerator refrigeration devices can be selected according to the actual situation.
Chillers may be used in many fields. The main application fields are:
⒈The chiller can be used in the supporting vacuum equipment. This type of chiller also meets the needs of high-quality vacuum equipment, such as molecular pumps, small vacuum coating machines, etc.; chillers are used in supporting semiconductor laser equipment. Due to its special structure, semiconductor laser equipment has higher requirements on water quality.
⒉ The chiller is used in supporting medical laser equipment. The unique water quality treatment characteristics of this type of chiller make it an ideal choice for supporting laboratory equipment for medical laser equipment. This series of chillers are also widely used in atomic absorption spectrometers, fermentation devices, reaction kettles, electrophoresis instruments, etc.
In the process of using the water cooler, you must pay attention to: first, liquid medium should be added to the tank before use, and secondly, the working power should be determined according to the model of the machine, the power of the power should be greater than or equal to the total power of the instrument, the power must be well grounded, and again The chiller should be placed in a dry and ventilated place, and the side that is approached is 400mm away from the obstacle. Finally, after the chiller is used, all switches should be turned off, and the power plug should be connected. Drain the liquid.
⒊The chiller can use the supporting experimental condensing equipment. For example, rotary evaporator, distiller, and condenser have the characteristics of controllable temperature, stable temperature and high condensation efficiency, which can effectively improve the recovery rate. At the same time, its fluid purification function can avoid the blockage of the circulation pipeline and the growth of microorganisms.
