Abstract
The invention discloses a method for increasing efficiency of a refrigeration unit of a vending machine. The method comprises the steps that a statistic cycle is set as T; sales situations of every t hours in each cycle are recorded, so that T*(24/t) period sales statistic information can be formed, wherein a sales amount in the sales statistic information at the initial moment is set as a maximum value; and t hours later, the vending machine reads a sales value for the next period after a current period in the previous statistic cycle, wherein refrigeration will be stopped if the sales value is smaller than a specific value and otherwise the refrigeration will be started; and a low-strength refrigeration maintenance state is started when a temperature reaches a refrigeration goal, temperature rise of addition N DEG C is allowed, and high-strength refrigeration is restarted when the temperature is N DEG C higher than the target temperature. According to the invention, energy consumption can be reduced greatly; no operator needs to set time for starting or stopping, and the applicability is very high; the temperature is allowed to increase again within a limit scope; and even during the periods with sales, over 10% of energy consumption can be reduced by the scheme in comparison with an accurate temperature control manner.
Description
Technical field
The present invention relates to being related to automatic vending machine technical field, particularly a kind of lifting automatic vending machine refrigeration unit efficiency
Method.
Background technology
Existing refrigeration plant lifts the method for refrigeration unit efficiency when using this field of automatic vending machine, not
Fully excavate its energy-saving potential, because automatic vending machine has use scene and the sales feature of itself, prior art cannot be led to
Cross statistics sales behavior to arrange refrigeration unit start and stop thus compressing the energy consumption of refrigeration unit further.
Content of the invention
The technical problem to be solved is, not enough for prior art, provides a kind of lifting automatic vending mechanism
The method of cold unit efficiencies.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of lifting automatic vending mechanism cold list
The method of first efficiency, comprises the following steps：
1）Set one for vending machine and stop cryogenic conditions such as：Sales volume is less than 10 yuan or sells number of times less than 2 times；
2）Set measurement period as T, in record a cycle, the sales situations of every t hour, form T*（24/t）The bar period sells
Sell statistical information, these sale result information sales volumes when initial are set as maximum；
3）Often through t hour, vending machine read the sales value of the next period of upper this period of measurement period, if should
The condition that value is less than step 1 setting then stops freezing, and otherwise opens refrigeration；
4）When temperature has reached refrigeration target, enter low-intensity and maintain refrigerating state it is allowed to temperature has the rise of+N degree,
When temperature N higher than target temperature degree then returns to high intensity refrigeration.
In the present invention, T is set as 7 days；T is 1 hour；N is 4 degrees Celsius.
Compared with prior art, the present invention had the advantage that for：The present invention can greatly save energy consumption, need not grasp
Go to arrange start-stop time, extremely well-adapted as personnel；Allow the limited rise of temperature, even if having in selling time section,
Compared with the mode of accurate temperature controlling, this scheme also can reach more than 10% energy consumption saving.
Brief description
Fig. 1 is the effective sale last Monday period scattergram of the present invention vending machine；
Fig. 2 is the refrigeration intensity distribution of the present invention vending machine this Monday.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the sales situations period distribution situation of the last Monday of automatic vending machine record.
During 0 point of this Monday, the sale of 1 point of period in record searched by vending machine, finds to sell very low, so closing
Refrigeration（0 point of period of Fig. 2）.Same during 1. -4 point, continue to close refrigeration（Fig. 21 to 4 point period）.
Come when the time at 5 points.The sale of 6 points of periods in record searched by vending machine, finds that sales situations are recovered, now sells
Refrigeration opened by cargo aircraft（Fig. 2）, so through the refrigeration in advance of 1 hour, client still can buy nice and cool beverage.When 6 points
Same（Fig. 2）.
Through the refrigeration of two hours, vending machine internal temperature reached target temperature.Now vending machine will freeze intensity fall
Low to maintain temperature model（As 7,8,10,11,13,14,16,17,19,20,22 points of periods in Fig. 2）It is allowed to temperature is slowly returned
Rise.Limit temperature until reaching tolerance returns strength cooling stages（Fig. 29,12,15,18,21 points of periods）.
Come when the time at 23 points.0 period that vending machine finds last week 2 does not sell, and now vending machine cuts out refrigeration（Figure
2 23 points of periods）.
Claims (4)
1. a kind of method of lifting automatic vending machine refrigeration unit efficiency is it is characterised in that comprise the following steps：
1）Set measurement period as T, in record a cycle, the sales situations of every t hour, form T*（24/t）The bar period sells
Sell statistical information, these sale result information sales volumes when initial are set as maximum；
2）Often through t hour, vending machine read the sales value of the next period of upper this period of measurement period, if it
The sales volume of the next period of front record is less than an arranges value, then stop refrigeration, otherwise opens refrigeration；
3）When temperature has reached refrigeration target, enter low-intensity and maintain refrigerating state it is allowed to temperature has the rise of+N degree,
When temperature N higher than target temperature degree then returns to high intensity refrigeration.
2. the method for lifting automatic vending machine refrigeration unit efficiency according to claim 1 is it is characterised in that T is set as 7
My god.
3. the method for lifting automatic vending machine refrigeration unit efficiency according to claim 1 is it is characterised in that t is little for 1
When.
4. the method for lifting automatic vending machine refrigeration unit efficiency according to claim 1 is it is characterised in that N is Celsius for 4
Degree.
