Description
Technical Field
[0001] This invention relates to the field of centrifuge technology, and specifically to an external water supply system and water supply method for a water-cooled centrifuge. Background Technology
[0002] The refrigeration system of a water-cooled centrifuge consists of an evaporator, a compressor, a heat exchanger, and a throttling device. Its refrigeration principle is as follows: First, the compressor draws in low-temperature, low-pressure gaseous refrigerant and compresses it into high-temperature, high-pressure gas. Then, it enters the heat exchanger together with externally supplied cooling water (chilled water) for heat exchange. After passing through the throttling device, it forms a low-temperature, low-pressure mist-like two-phase flow. When it passes through the evaporator coil, it absorbs heat from the water-cooled centrifuge cavity. At this time, the liquid refrigerant vaporizes, completing the heat absorption and refrigeration. Finally, it is drawn into the compressor to enter the next refrigeration cycle.
[0003] In the production lines of biopharmaceutical and bioproduct industries, large-capacity, low-speed refrigerated centrifuges are mostly used for mass production. These workshops have a large number of centrifuges, which are densely packed and are used for continuous, large-volume sample separation. Conventional centrifuges mainly use air-cooling systems for heat exchange, which causes a large amount of heat to accumulate and remain in the workshop. This leads to an increase in the ambient temperature in the workshop, affecting the temperature control and heat dissipation performance of the centrifuge itself, which inevitably results in poor sample separation.
