Problems solved by technology
Its shortcoming is: the leakage of ammonia refrigerant liquid from each connection position of the ammonia pump is relatively large, and it is inevitable to replenish the ammonia refrigerant to the refrigeration system regularly (almost once every few days). Disadvantages, because the cost of ammonia refrigerant is not much higher than that of water, besides, water cannot be used as a medium in places below 0°C
[0006] Obviously, the premise of solving the above problems or the biggest problem is: the above leakage problem of the liquid pump, that is, the refrigerant liquid pump must be solved, because it has directly related to the use cost of the refrigeration system

Embodiment Construction
[0015] After passing through the condenser 10 of the refrigeration system, it becomes a liquid refrigerant, and after entering the low-pressure liquid storage barrel device D for temporary storage, because it is covered with a thermal insulation layer, the liquid refrigerant will not absorb heat and evaporate in this intermediate transition container, only when it is refrigerated After the agent liquid pump B is pumped into the evaporator 10 of the high-rise warehouse, the normal endothermic boiling, evaporating and cooling work will be carried out through heat exchange with the outside world.
[0016] Due to the presence of the metal sealed casing 7 that constitutes the refrigerant liquid pump B, the high-pressure liquid refrigerant in the pump body 2 is prevented from forcibly leaking (leaking) in a large amount from the shaft seal of the transmission shaft 6 and then entering the atmospheric space to cause waste. The main reason is to allow the large amount of electric heat ...

The invention relates to a fully sealed refrigerant pump and a usage method thereof in refrigeration systems of high-rise buildings, which is implemented by two key measures of adding a sealing housing (7) (the sealing structure form being a fully sealed screen between a pump and a dragging motor in a liquid pump and external space by welding metal materials) in the combination structure of a pump body (2) and the dragging motor thereof and a gas pressure equalizing pipe (3) which communicates an interface of a cavity space formed between the sealing housing (7), the pump (2) and the dragging motor, and a pipe connection mode of the liquid refrigerant pump (B) device (system) containing the pump body (2) in the refrigeration air conditioning systems of high-rise buildings. The invention is most suitable for use in the high-rise or building refrigeration air conditioning system.
Description
technical field [0001] The invention relates to the structure of a fully sealed refrigerant liquid pump and its application method in the refrigeration system of high-rise buildings, especially the application method in the refrigeration and air-conditioning system of high-rise or super high-rise buildings. Background technique [0002] At present, in the refrigeration and air-conditioning systems of high-rise or super high-rise buildings, due to the pressure formed by the compressor in the refrigeration system, it is difficult to press the low-pressure liquid refrigerant up, and it usually relies on the secondary cooling capacity composed of water and its supporting water pumps. The cold medium distribution device assists in the delivery of cold energy. [0003] ——Since the leakage problem of the liquid pump has not been solved, no matter how large the water leakage is when the water pump is used, it will basically not affect the use cost of the refrigeration system, althou...
