Technical Field
The invention relates to the technical field of cooling systems, in particular to a magnetic suspension phase change cooling system.
Background
As computers and servers develop, machine room cooling systems become increasingly important. One of them is a liquid cooling technique, which is a method of cooling computers and servers by using a liquid; liquid cooling techniques can be divided into two main types: direct liquid cooling and indirect liquid cooling. Direct liquid cooling refers to direct introduction of liquid into a heat sink assembly of a computer or server for cooling by direct contact and absorption of heat. The liquids generally used are media with high heat conductivity properties, such as water or special cooling liquids. The direct liquid cooling technology can effectively transfer heat from a heat radiation source to liquid and carry the heat out of a machine room through a circulating system. Indirect liquid cooling refers to the use of a liquid as a heat transfer medium to create a heat exchanger between a computer and a server. The heat exchanger transfers the heat generated by the heat dissipation assembly to the liquid, and then the liquid is brought to a cooling tower or cooling equipment outside the machine room for heat dissipation. This way, direct introduction of liquid into the interior of the computer can be avoided, reducing the potential risk of liquid entering the device.
The invention discloses an air-conditioning type cooling system for a pump station motor and an application method thereof, wherein the air-conditioning type cooling system comprises a compressor, a condenser, an evaporator, a refrigerant, a fan, a high-pressure controller, a dry filter, an expansion valve and a throttle valve.
Magnetic suspension compressors are an advanced compressor technology, and a magnetic suspension bearing system is adopted to realize non-contact rotary motion. Compared with the traditional mechanical bearing, the natural cooling is an energy-saving technology with better energy-saving effect, which is well known, not only saves a great amount of electricity charge for users, but also accords with the strategy of global low-carbon energy saving, and the outdoor air temperature is lower than 0 ℃ in the north China, northwest and northeast areas, which is a considerable percentage of the total year, and the natural cold source is used as the primary measure for energy saving. The energy-saving effect of the fluorine pump energy-saving unit is obvious. But has not been widely used in natural cooling technology. Many data centers are installed and used with constant temperature and humidity precision air conditioners. Currently, these data centers are also faced with energy saving modifications.

Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Examples: the magnetic suspension phase change cooling system comprises a water cooling system 5, a magnetic suspension fluorine pump refrigerant system 6 and an emergency cooling system 7, wherein the water cooling system 5 comprises a cooling tower 8, a dosing device 9 and a cooling pump II 18, the magnetic suspension fluorine pump refrigerant system 6 comprises a shell-and-tube heat exchanger 10, a magnetic suspension compressor 11, a precise air conditioner 12 and a fluorine pump 13, the magnetic suspension fluorine pump refrigerant system, the precise air conditioner and the fluorine pump 13 are connected in series through a pipeline system, the emergency cooling system 7 comprises a cold storage tank 14, a refrigerating pump 15, a water chilling unit 16 and a cooling pump I17, and the magnetic suspension compressor 11 comprises a compressor body, a two-stage compression impeller, a rotor, a driving shaft, a synchronous motor, an electromagnetic bearing, an adjustable inlet guide vane, a power conversion system, an electromagnetic bearing control system and a soft pneumatic control system.
The cooling water in the water cooling system 5 transfers heat to the air through the cooling tower 8, the low-temperature cooling water takes away the heat of the refrigerant in the magnetic suspension fluorine pump refrigerant system 6 through the shell-and-tube heat exchanger 10, the refrigerant transfers heat through phase change between the shell-and-tube heat exchanger 10 and the precise air conditioner 12 through the action of the magnetic suspension compressor 11 and the fluorine pump 13, the heat in the machine room is taken away, thereby achieving the purpose of reducing the temperature of the machine room, ensuring the stable operation of IT equipment in the machine room, reducing the heat exchange of primary refrigerant and water by the refrigerant directly exchanging heat with the hot air of the machine room compared with the traditional cooling mode, improving the heat exchange efficiency, also increasing the time of directly utilizing the atmosphere low-temperature environment, improving the natural cooling time, and improving the safety of the machine room without water system entering the machine room at the tail end.
The magnetic suspension compressor 11 discharges from the air conditioning compressor through high temperature and high pressure freon, enters the condenser, releases heat to copper pipe cooling water, condenses into medium temperature and high pressure freon liquid, then reduces pressure through the throttle valve into low temperature and low pressure liquid, enters the evaporator, absorbs heat from the chilled water flowing through the copper pipe in the evaporator shell, gasifies into low temperature and low pressure gas, then is sucked into the compressor, is discharged into high temperature and high pressure gas through secondary compression in the compressor, and finally achieves the purpose of reducing temperature through the circulation.
The fluorine pump 13 is matched with a machine room air conditioner for use, and a refrigeration compressor operates in summer; when the outdoor temperature is lower than the set point, the operation of the fluorine pump energy-saving system is automatically switched to ensure the safe and reliable operation of the air conditioner of the machine room all the year round; the compressor power was about 10kW and the fluorine pump power was about 1 kW. Under the condition of outdoor low temperature, the refrigerating capacity of the fluorine pump 13 is basically equal to the refrigerating capacity generated by the 10kW compressor, which is the key point of energy conservation of the fluorine pump 13.
