Description
Technical field
The present invention relates to automatic vending device, more particularly to i.e. hot cold-instantly type trans critical cycle automatic vending device and its confession
Pallet piling up method.
Background technology
As the improvement of people's living standards, the quickening of movement of population speed, automatic vending machine is this conveniently to be sold
Cargo interests formula receives the welcome of consumer and retailer, and demand is continuously increased.Although single automatic vending machine energy consumption is not high,
But it is due to its substantial amounts, overall energy consumption is still than more significant.In addition conventional automatic vending machine all only provides freezing mostly
Commodity, without heating function, it is impossible to meet the extensive demand of crowd.It is therefore desirable to from saving and meet crowd demand's angle pair
Automatic vending machine makes improvement.
Traditional automatic vending machine uses the structure similar to refrigerator.All there is a thermal-insulating body in i.e. all goods
In, cold is provided by refrigeration system, all goods therein are maintained at a relatively low temperature.In commodity selling, from
Commodity are taken out in casing.Because all only some commodity can be sold daily, such most energy consumption of system is whole
The insulation of individual casing.It is overall to need substantial amounts of high-quality insulation material because casing is than larger, while to the system of kind of refrigeration cycle
Cold and refrigeration work consumption have the high requirement of comparison.
Chinese patent literature CN203179154 U give a kind of device to beverage vending utensil is heated or freezed,
It is only heated or freezed to the beverage come close to outlet, can so reduce the energy for heating or freezing to overall space
Consumption.But this mode can not tackle the period of harvest yield change well, when the amount of selling goods is very big, this mode substantially can not
Meet the demand that cold drink is provided；When the amount of selling goods is small, it is equally higher that it is incubated energy consumption.Further, since by Import ＆ Export Department
Divide and remainder can not be sufficiently spaced from, the reduction that it is incubated energy consumption is unsatisfactory.
Conventional dispensers with only the cold of kind of refrigeration cycle vaporizer side generation, and the heat of condensation end is directly arranged
Remove.This way is not only the waste to energy, while will also result in detrimental effect to environment.In order to improve the profit of energy
With rate, Chinese patent literature CN101285034A, which provides one kind, can utilize in kind of refrigeration cycle in evaporator cold simultaneously and cold
The method of heat in condenser.But its general refrigerant for using, condensation end temperature can only achieve 20~35 DEG C, such temperature
It is far from being enough to heat commodity, or the time of heating can be very long, it is impossible to the need for meeting consumer.
Also there is a common defect in two above patent, i.e., carry out hot preservation to a large amount of food, by food for a long time
It is stored in thermal environment, it is easy to occur to go bad, is unfavorable for long-term preservation, it is therefore necessary to which synthesis improvement is carried out to it.
The content of the invention
The invention provides a kind of i.e. hot cold-instantly type trans critical cycle automatic vending device, only when user needs kinds of goods,
Kinds of goods are freezed or heated, discontinuous operation, and freezed and freezed by trans critical cycle, effectively reduce energy consumption.
Storage area is provided with a kind of i.e. hot cold-instantly type trans critical cycle automatic vending device, including casing, the casing

With；Apparatus of the present invention are only in kinds of goods demand, and cooling and warming cycling element just works, and the automatic vending of this and prior art is filled
Put and open cooling and warming circulation difference for a long time, play the effect of energy-conservation；And setting incubator to store existing customer need not
Goods not much in demands product or goods in great demand product, due to measure smaller, incubator small volume, in the case of automatic vending machine finite volume, insulation
It is thicker that structure can be set, and heat insulation effect is guaranteed.
The present invention refrigerant circulating process be：Refrigerant is low temperature low pressure gas at compressor air suction mouth, through overvoltage
After compression process at exhaust outlet of compressor be high temperature and high pressure gas.After condenser at condensator outlet be high pressure saturated solution
Body or subcooled liquid, refrigerant enter regenerator, and temperature further reduces realization supercooling；Refrigerant enters storage after regenerator
Flow container, fluid reservoir is opened after restricting element, and refrigerant is changed into low-pressure gas-liquid mixture and enters evaporator, the liquid in evaporator
It is changed into the vapor phase refrigerant (there may be liquid phase remaining) of low-temp low-pressure after attracting thermal evaporation, refrigerant all changes is made by regenerator
For gas phase, whole circulation is completed into compressor.
The refrigerant that the refrigerant that condensator outlet flows out flows out with evaporator outlet is made heat exchange by the regenerator.It is cold
Condenser outlet refrigerant temperature after regenerator, which further lowers, enters supercooled state, effectively improves system COP, evaporator goes out
Mouth refrigerant liquid phase constituent all evaporates into full gas phase state, prevents that " liquid hammer " phenomenon occurs in compressor.
Wherein described restricting element is choke valve, expansion valve, capillary or U-tube.Described heat-producing machine is condenser

Enter fluid reservoir after heat release.Device for being provided with cold end accumulator, the part cold when being cooled down to beverage is stored up by cold end
Energy device is provided, if the cold of storage enough, is directly freezed using cold end accumulator.
During customer selecting " hot drink ", beverage enters heat-producing machine from normal temperature storage unit；Between restricting element and fluid reservoir, throttle
Flow control valve is opened between element and evaporation element, between compressor outlet and refrigerator, compressor start.Compressor outlet
High temperature and high pressure gas enter heat-producing machine, and the heat release in heat-producing machine, and then heating temperature is raised beverage.After the completion of heating, hot drink from
Launch to client hot drink outlet.Refrigerant then enters fluid reservoir storage by heat-producing machine outlet.
Device for being provided with hot junction accumulator, partial heat during to beverage heating is provided by hot junction accumulator, such as
The heat of fruit storage enough, is then directly heated using hot junction accumulator；Device for being provided with cold end accumulator, gas after throttling
Liquid two phase refrigerant enters cold end accumulator and releases cold.
During currently without customer demand, device is " standby " working condition.Fluid reservoir outlet flow control valves, refrigerant inlet
Flow control valve, heat-producing machine inflow control valve, hot junction and cold end accumulator inflow control valve are turned off, and compressor is not
Work, now rating of set is minimum.
Beneficial effects of the present invention：
The automatic vending device and method of the present invention, cooling and warming cycling element compressor discontinuous operation is only needed in client
Heated, most of beverage is then stored at normal temperatures, effectively prevent under the quality for heating and causing repeatedly immediately when seeking hot drink
The problems such as drop and shortened shelf life, beverage flavor more preferably, is more beneficial for the healthy of people；Storage is with the thermogenetic cold of system
Or the heat that refrigeration is produced, and used during the follow-up supply of material, device discontinuous operation effectively reduces energy consumption, saves energy；Only
By completing cooling or heating to beverage in a cooling and warming EGR, the complexity of system is reduced, makes system
Operation is relatively reliable.
