Problems solved by technology

Its shortcoming is that the requirements for water quality are very high. In order to slow down the scale formation in the pipe network that distributes cooling capacity (affecting heat conduction), it is necessary to use chemicals to dredge the huge heat pipe network formed by the water pipe network every one or two years. switching system
It can be imagined that due to the comprehensive involvement of water in the air conditioning system, the maintenance workload and maintenance cost of the prior art are considerable

Embodiment Construction

[0015] Depend on figure 1 hint:

[0016] Because only relying on the strength of the high and low pressure difference caused by the compressor 2 in the refrigeration and air conditioning system, it is difficult to directly drive the rated liquid refrigerant flow through the tortuous pipeline (large flow resistance), and then enter tens of meters, or even hundreds of meters. Refrigeration and air conditioning of relevant rooms in super high-rise buildings above 10000 meters.

[0017] Therefore, when the refrigerant in a low-pressure state passes through the restrictor 8, when it enters and passes through the evaporator P in the intermediate medium heat exchanger 5, it transfers the cooling capacity generated during the evaporation process of the liquid refrigerant to the evaporator driven by the water pump. The water of the cold medium is transferred by the water for the second time.

[0018] For this reason, in a conventional refrigeration and air-conditioning system, a refr...

Abstract

A cooling air conditioner scheme without cold medium (water) for high building is characterized by that the refrigerant boosting and distributing system composed of refrigerant pump and low-pressure liquid tank is additionally used in the cooling air conditioner engineering to replace original cold medium distributing system. Its advantages are low cost, and high air conditioning effect.

Description

Technical field: [0001] The invention relates to the waterless design scheme technology of refrigeration and air-conditioning engineering facilities of super high-rise buildings, in particular to the technology of adopting refrigerant pressurized distribution device to realize the above waterless design scheme. Background technique: [0002] In current high-rise building projects, especially in the design of refrigeration and air-conditioning systems in super high-rise building projects, it is the best technical means to use water as the cooling medium to transfer cooling capacity to terminal equipment (such as: fan coil units and water-cooled wind cabinets, etc.). [0003] This is because it is difficult to directly drive the rated flow rate of liquid refrigerant by relying only on the high-low pressure difference caused by the compressor in the refrigeration and air-conditioning system. Room air conditioning in the building. Therefore, it is usually completed by using wat...
