Refrigeration compressor performance test bench, compressor performance test teaching model
Compressor (compressor), a driven fluid machinery that lifts low-pressure gas to high-pressure gas, is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby realizing compression → condensation (heat release) →expansion→evaporation (heat absorption) refrigeration cycle.

World's Largest Umbilical Cord Blood Bank, 500000 Enabled
On April 21, the new bank of Beijing umbilical cord blood hematopoietic stem cell bank was completed and put into use in Beijing Economic and Technological Development Zone, thus completing the third expansion since the establishment of the bank in 1996. It is reported that the new library has a total investment of 0.12 billion yuan, a construction area of nearly 10,000 square meters, and a library capacity of 500000 copies. It is currently the largest umbilical cord blood hematopoietic stem cell bank in the world. ● 24-hour monitoring system "escort" liquid nitrogen library The new library consists of liquid nitrogen library, laboratory, purification work area, data database and other parts. Among them, the liquid nitrogen library has installed more than 100 storage tanks, which are the largest single liquid nitrogen tanks in the world today, each tank can store 5000 specimens. "Umbilical cord blood stem cells need to be stored in liquid nitrogen, and their storage process must be absolutely safe." Dr. Gao Feng of Beijing umbilical cord blood bank told reporters that all tanks are connected by vacuum pipes, and the terminal is connected to an outdoor storage tank with 30000 cubic meters of reserves, which can ensure 24-hour uninterrupted replenishment of liquid nitrogen. In addition, the status of all liquid nitrogen storage tanks and the replenishment of liquid nitrogen are controlled by the central control room, from which the status of the storage tanks can be monitored, and any information of umbilical cord blood stem cells can be retrieved at any time. At the same time, the monitoring system installed in the library can implement 24-hour monitoring. ● Donor information is disclosed as an active donation barrier. There are about 65700 umbilical cord blood stem cells in Beijing umbilical cord blood bank, of which nearly 50000 are voluntarily funded and stored, and only 10000 are voluntarily donated by citizens. "People who voluntarily donate cord blood stem cells often have to undergo the test of personal information being made public." In this regard, Gao Feng explained that some genetic diseases only develop after 3 to 5 years. Therefore, in order to ensure that the donated cord blood stem cells do not contain any genetic diseases, the Beijing Cord Blood Bank must conduct long-term health status of donors. track. "From illness to medical records to changes in home address, we must be informed in time, which makes it difficult for many people to accept psychologically." Citizens who actively donate cord blood stem cells, once they and their families suffer from leukemia and need hematopoietic stem cell transplantation, they will have the priority of matching in Beijing cord blood bank. ● Millions of patients wait for hematopoietic stem cells every year. There are millions of patients waiting for hematopoietic stem cell transplantation in my country every year. There are 40000 new patients with leukemia every year, of which more than 50% are children. Umbilical cord blood stem cell transplantation has become an important means for the treatment of leukemia. Umbilical cord blood stem cell transplantation in China has achieved more than 500 cases of clinical application. At present, the Beijing umbilical cord blood bank uses umbilical cord blood for the treatment of more than 200 diseases, of which 85 umbilical cord blood helps 70 patients complete hematopoietic stem cell transplantation, and the success rate of umbilical cord blood transplantation is more than 80%. The cord blood stem cells provided by the Beijing Umbilical Cord Blood Bank are not only used in various common diseases such as leukemia, severe aplastic anemia, thalassemia, myelodysplasia, lymphoma, etc., but also applied to mucopolysaccharidosis, Langerhans cell histiocytosis, WAS syndrome, severe combined immunodeficiency, Parkinson and more than 20 diseases.
In 2005, our company was named "Zhejiang Province Teaching Instrument Industry Advanced Collective"
