Problems solved by technology

Its disadvantages are: the leakage of ammonia refrigerant liquid from each connection position of the ammonia pump is large, and it is inevitable to replenish the ammonia refrigerant to the refrigeration system regularly (almost once every few days).
If the refrigerant ammonia water (about 0.2 yuan per kilogram) is changed to Freon F12 (about 40 yuan per kilogram) or its homogeneous substitutes, this will inevitably increase its refrigeration cost by nearly two hundred times

Embodiment Construction

[0013] 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.

[0014] 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 ...

Abstract

The invention relates to a fully sealed refrigerant pump and an application thereof in refrigeration systems of high-rise buildings. Structurally, the invention is realized by additional arrangement of, based on a composite structure of a pump body (2) and a traction motor thereof, a sealed shell (7) (the optimal sealing structure is fully sealing of the pump body and the traction motor from surroundings by metal welding) and an interface equipped with a gas pressure equalizing pipe (3), and pipeline connection of the liquid refrigerant pump (B) device (system) containing the pump body (2) in the refrigeration systems of low-temperature cold storage warehouses in high-rise buildings.

Description

Technical field: [0001] The invention relates to the anti-leakage technology of the refrigerant liquid pump and the use method of the liquid pump in the refrigeration system of 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 the secondary cooling system composed of water and its supporting water pumps is usually used. The volume transfer cold medium medium distribution device assists in the delivery of cold energy. [0003] In the low-temperature refrigeration system of high-rise cold storage, the ammonia refrigerant pressurized distribution device with non-sealed ammonia pump (refrigerant can leak from the shaft seal of the pump to the atmospheric air) as the main body was successfully used first, realizing the high-rise low-t...
