Abstract
The utility model discloses a kind of energy-saving vacuum precoolers, including vacuum chamber, pumping air vacuum pump, ice filling container；Ice filling container is placed in vacuum chamber, and ice filling container is uncovered structure.Under vacuum conditions, ice-out is used to carry out the intracorporal vapor of condensate vacuum case for the phase transformation cooling capacity of water, it is not necessarily to the mating steam vacuum plant that draws water to reach energy-saving vacuum Precooling unit, saves the operation energy consumption for the steam vacuum plant that draws water, energy-saving vacuum precooler low cost, low energy consumption.
Description
Technical field
The utility model relates to refrigeration technology field, especially a kind of energy-saving vacuum precooler.
Background technique
With vacuum pre-cooling technology, cooling process equipment.At low pressure, the boiling point of water reduces, and evaporation latent heat increases.
It is depressed in a normal atmosphere, the boiling point of water is 100 DEG C, heat of evaporation 2256KJ/kg；When pressure drops to 610 pa, water
Boiling point be 0 DEG C, heat of evaporation 2500KJ/kg.With the reduction of air pressure, the boiling point of water is reduced, and the water of evaporation unit quality
Consumed heat increases.Vacuum precooling machine extracts the intracorporal air of vacuum tank and vapor using vacuum pump to reduce vacuum tank
Internal air pressure makes water be vacuum-treated interior rapidly with the evaporation of lower temperature, in the process, consumes more heat transfer, do not having
In the case where having external heat source, vaporization phenomenon occurs for cooled object surface and internal Free water, takes away itself and bad border heat, reaches
To the effect that cools.Vacuum pre-cooling process cooling rate is fast, of good preservation effect, is widely used in agricultural product, hot-working product
Deng pre- cold working.Conventional vacuum precooler mainly includes vacuum chamber at present, pumping air vacuum pump, draw water steam vacuum plant three
Part.There are two types of forms at present for the steam vacuum plant that draws water, and one is the ejector vacuum pumps using high-pressure hydraulic pump or high steam
It extracts vapor out and generates vacuum, another kind is to generate vacuum using the evaporator of refrigeration unit come condensed steam.Due to true
A large amount of vapor can be generated in empty precooling process, two kinds of steam vacuum plant energy consumptions of drawing water are all very high, and corollary equipment at
This is also very high.Therefore the prior art has much room for improvement and develops.
Summary of the invention
Technical problem to be solved by the utility model is: providing a kind of energy-saving vacuum precooler, it is configured with ice filling container,
Under vacuum state, uses ice-out to carry out the intracorporal vapor of condensate vacuum case for the phase transformation cooling capacity of water and form vacuum, to reach section
Energy vacuum pre-cooling unit is not necessarily to the mating steam vacuum plant that draws water, and saves the purpose for the steam vacuum plant operation energy consumption that draws water.
The technical solution of the utility model is: a kind of energy-saving vacuum precooler, including vacuum chamber, pumping air vacuum
Pump.The energy-saving vacuum precooler is configured with ice filling container, and the ice filling container is placed in vacuum chamber, and the ice filling container is
Uncovered structure facilitates vapor to enter ice filling container in ice surface condensation, and it is water that ice, which absorbs heat to melt, and vapor releases heat
It is condensed into liquid water.Ice filling container can also be placed in outside vacuum chamber, be connected to by pipeline with vacuum chamber.The source of ice can be with
It is natural ice and snow, winter ice cell ice storage, ice making heating by-product ice, ice-maker makes ice etc..
The beneficial effects of the utility model are: providing one kind is configured with ice filling container, without the mating steam vacuum holding that draws water
It sets, the low energy consumption for the steam vacuum plant operation energy consumption that do not draw water, inexpensive energy-saving vacuum precooler.
Detailed description of the invention
Fig. 1 the utility model structure diagram；
Description of symbols: 1. vacuum chambers；2. shelf；3. ice filling container；4. taking out air vacuum pump.
Specific embodiment
Embodiment: refering to fig. 1, a kind of energy-saving vacuum precooler, including vacuum chamber 1, pumping air vacuum pump 4, ice filling appearance
Device 3, shelf 2；It further include detection control apparatus；Ice filling container 3 is placed in vacuum chamber 1, and ice filling container 3 is uncovered structure, side
Just vapor enters ice filling container 3 in ice surface condensation；Air vacuum pump 4 is taken out to be connected by pipeline with vacuum chamber 1.Energy conservation
The operational process of vacuum precooling machine is that cargo is placed on shelf 2, and borneol is placed in ice filling container 3, and shelf 2, ice filling container 3 are set
In in vacuum chamber 1, closing the chamber door of vacuum chamber 1, air vacuum pump 4 is taken out in starting, and the air in vacuum chamber 1 is constantly taken out
Out, vacuum degree is higher and higher in vacuum chamber；Under vacuum conditions, vapor enters ice filling container 3 in ice surface condensation, and ice is inhaled
Receiving heat thawing is water, and vapor releases heat and is condensed into liquid water, and the ice-out in such ice filling container 3 is mutually turning cold for water
Measure the vapor in continuous condensate vacuum cabinet 1；The Free water of cargo surfaces and inside is rapidly in vacuum chamber 1 with lower
Temperature evaporation consumes more heat transfer in the process, and in the case where no external heat source, be cooled cargo surfaces and inside
Vaporization phenomenon occurs for Free water, takes away itself and bad border heat, reaches rapid cooling cooling effect.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment is not to limit
The scope of the patents of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, is intended to be limited solely by this case
In the scope of the patents.
