Equipment for producing chilled water and distilled water

Abstract

Based on the pain points of refrigeration design and operation of modern urban mansions, large-scale refrigeration of air conditioners in cities generally takes water as a secondary refrigerant, and a traditional water chilling unit is high in refrigeration energy consumption, complex in system, huge in water consumption and power consumption, complex in later-stage water treatment and high in investment. The structure of a refrigeration system is simplified, and water is adopted as a refrigerant because the latent heat of water gasification is very high. Water directly evaporates to absorb heat, and can be condensed and recycled after being compressed to serve as a refrigerant or extracted to serve as distilled water. Water treatment is simplified, the problem is that impurities in water are concentrated and condensed, and an ultrasonic descaling sludge pump is used for pumping in a special evaporator structure design. The distilled water can produce higher economic value.

Description

Technical Field

[0001] This product is used in urban or industrial cold water systems Background Art

[0002] In cities, residential buildings or commercial spaces and industrial facilities in cities generally use water cooling systems for refrigeration. Due to its large cooling capacity, water is required as a coolant. In existing chiller systems, chillers have considerable energy consumption. In water systems, the cooling side needs to be treated and sewage discharged regularly, resulting in considerable waste and pollution, and water treatment is a considerable investment. The present invention is to solve the problems existing in existing water refrigeration systems. Summary of the invention

[0003] The present invention is a new type of refrigeration system using water as cooling medium and refrigerant. Its principle and related calculations are as follows:

[0004] Important parameters: specific heat of water 4.2kj / kg℃, latent heat of vaporization of water 1600-2200kj / kg, boiling point of 1kp water is 7 degrees Celsius. We use a vacuum pump to reduce the water pressure to one kPa, and then exchange heat with the refrigerant water. Under the continuous action of the vacuum pump, 7 degrees Celsius chilled water will be produced, which is fully in line with the needs of the national economy. At the same time, 7 degrees Celsius water vapor is produced. We can discharge these water vapors directly into the condenser through the compressor. Condensed water can be produced by cooling with a fan, and this part of water can be re-injected into the evaporator. It can also be discharged directly from the condenser. As distilled water, the value of distilled water is still considerable. If these conditions are not met, it can be discharged directly into the atmosphere.

[0005] Description of the drawings: Figure 1 As shown in the schematic diagram of the present invention, the boiling point of water is reduced by low pressure to absorb heat as an evaporator. After being compressed and entering the condenser, the distilled water coming out of the condenser can be used directly as a refrigerant, or it can be directly discharged and sold as distilled water. Through my design, the complexity of the refrigeration structure can be greatly reduced, while saving energy as much as possible and generating economic benefits.

Claims

1. This product is a chilled water and distilled water production equipment. The vacuum pump reduces the water pressure to one kilopascal, and then exchanges heat with the refrigerant water. Under the continuous action of the vacuum pump, 7 degrees Celsius chilled water will be produced, and 7 degrees Celsius water vapor will be generated at the same time. These water vapors can be directly discharged into the condenser through the compressor. Condensed water can be produced by cooling with a fan, and this part of water can be re-injected into the evaporator. It can also be directly discharged from the condenser. It can be used as distilled water or discharged into the atmosphere. ① Evaporator: Most of it is filled with water. The heated cold water transfers heat to the evaporator through the surface cooler placed in the evaporator. The evaporator, due to the low-pressure state extracted by the vacuum pump, causes the water molecules to evaporate rapidly, taking away the heat above the surface cooler. ②Condenser: The water vapor of about 1,000 Pa extracted from the vacuum pump is pressurized to about 30 kilowatts, at which time high-pressure superheated steam will be formed in the condenser. ③Vacuum pump: The operating pressure of the evaporator is relatively low, and a vacuum pump with a large flow rate and a certain compression ratio is required to draw the vacuum. ④ Compressor: responsible for compressing the low-pressure water vapor extracted by the vacuum pump. ⑤ Cooling fan: responsible for dissipating the high-temperature superheated gold vapor from the condenser. ⑥ Water replenishment solenoid valve: inject tap water or vacuum-treated water into the evaporator. ⑦Distilled water outlet: to discharge the distilled water produced by condensation. ⑧ Scale discharge port: The inevitable soluble or insoluble solids in the river water are precipitated into the scale sedimentation tank and discharged through the scale discharge port. ⑨Surface cooler: serves as a chilled water heat exchange component. ⑩ Return water solenoid valve: can return part or all of the condensed water to the evaporator. ⑪ Exhaust vacuum pump: The non-condensable gas in the water is discharged into the atmosphere.
