Specific embodiment
Ambient temperature is affected for the temperature of automatic vending machine internal environment, and interior environment temperature is often
It is intended to environment nowadays and changes, the present embodiment provides the acceptable temperature range and one of ambient temperature
The temperature range of a internal environment for wishing to maintain, and the temperature range of internal environment is located at the acceptable of ambient temperature
In temperature range, fluctuated in two sections if being somebody's turn to do temperature, then it is assumed that environment nowadays are in internal environment and can connect
In the temperature fluctuation range received, without being adjusted to interior environment temperature.
And existing temperature control, mainly consider internal temperature to be arranged upper and lower threshold value, monitoring temperature is once more than
Threshold value is freezed accordingly immediately or heating processing, which can not cope with ambient temperature mutation or interior
Portion's environment has the situation of of short duration interference, and temperature control can be made not normal, and refrigeration and heating are by frequent starting.
For example, when external environment is lower than its low temperature threshold, and internal environment meets with heat interference, interior environment temperature rises sharply,
Higher than its high temperature threshold value, then start refrigeration cool-down, however external environment has been currently low temperature, once heat interference disappears, inner loop
Border is currently at still in refrigerating state, and because of external environment low temperature, interior environment temperature is lower, can exceed low temperature threshold quickly
Value, starts heating beyond threshold value immediately, however the heating that can not also prevent temperature from controlling far more than low temperature threshold, thus start
Cool down caused by compensation heat interference, it may be desirable to be offset for a period of time with thermal energy, it is seen then that of short duration heat interference is so that internal environment
Temperature, which is adjusted, to be generated for the refrigeration needed, and needs subsequent more heats also to exclude the influence of the interference, anti-interference
Ability is weaker.
As shown in Figure 1, 2, a technical solution of the invention is: a kind of temprature control method, including ambient temperature
Control and internal environment control, Tch is internal high temperature threshold value, and Tcl is inner cryogenic threshold value, and Teh is external high temperature threshold value, Tel
It is outer low temperature threshold value；The temperature range of internal environment is located in the temperature range of ambient temperature；Judge external environment temperature
Degree≤Tel, then interior environment temperature adjusting only allow to heat, and interior environment temperature≤Tcl, interior environment temperature adjusts starting system
Heat, until interior environment temperature > Tcl, stops interior environment temperature and adjust；Interior environment temperature >=Tch, interior environment temperature
Adjusting does not start refrigeration still, and Tcl < interior environment temperature < Tch, interior environment temperature adjusting does not start refrigeration and heating is internal
Portion's environment temperature is adjusted；
As a kind of comparative example, the prior art is a kind of automatic vending machine of packed meal, can also be used certainly for example right
The high any automatic vending machine of product temperature required precision, usually to keep storehouse temperature is 0~4 DEG C, is not had to temperature outside library
It limiting, temperature reaches -8 DEG C outside current library, and library internal cause is opened the door plus goods, light influence etc. in transport mechanism motor action or library,
It generates so that reaching 7 DEG C of heat interference (there may be temperature interferences there are also other producing methods certainly) in library, due to being more than interior
The high temperature upper limit in portion, internal temperature adjusts starting refrigeration, library external environment low temperature, if at this point, heat interference disappears, still in system in library
Refrigeration and outdoor low temperature collective effect restart heating so that storehouse temperature declines rapidly at this time outside cold and library, for cooling down
Trend is not easy to intercept, and this violent cooling and corresponding largely heating, holds so that storehouse temperature is adjusted
It is ceaselessly vibrated between the upper and lower line of temperature in Yi Ku, so that refrigeration, heating start and stop are stopped.Existing method is dry for heat as a result,
It is more to disturb consumption and compensation heat, and temperature control system is easy start and stop and stops.This method is referred to as the control of two-part temperature.
In this kind of scheme, as a specific embodiment, it is a kind of automatic vending machine of packed meal, usually keeps library
Interior temperature is 0~4 DEG C, and it is -2~6 DEG C that temperature, which sets its threshold range, outside library, when temperature reaches -8 DEG C outside library, is only allowed at this time
Internal temperature, which is adjusted, has heating starting, and without cooling activation, and library internal cause is opened the door plus goods, transport mechanism motor action or
Light influences etc. in library, generates that (there may be temperature is dry there are also other producing methods certainly so that reaching 7 DEG C of heat interference in library
Disturb), freeze since inside does not allow to start, thus, internal temperature adjusting is failure to actuate, and is Ku Neire interference drop by low temperature outside library
Temperature, and in lower than 4 DEG C stopping refrigeration, it keeps storehouse temperature at 0~4 DEG C, that is, utilizes hot interference compensation ambient temperature, if this
When, heat interference disappears, and in library still within the scope of 0~4 DEG C (more stable or small-scale adjustment), once being lower than 0 DEG C, then opens
Dynamic heating, to compensate the low temperature of external environment, this method is referred to as the control of three-stage temperature.Present invention essence is to utilize as a result,
Outer low temperature resists heat interference, and practical is also to have used hot interference and heated from starting, disappears, not will lead in heat interference
The cataclysm of temperature and violent adjustment, the start and stop that not will lead to such frequency in comparative example stop.
Equally in face of of short duration heat interference, the present invention will control by simple storehouse temperature index increase in library, outside library it is same
When monitor, and propose in library external environment temperature to be lower than low temperature threshold, then environment temperature should tend to low temperature in library, of the invention
Under control strategy, library external environment temperature has been lower than low temperature threshold, and interior environment temperature adjusting does not start refrigeration still, by external rings
The low temperature in border reduces the temperature of internal environment, thus occurs for heat interference, and internal environment of the invention not will start refrigeration and adjust
Section is only lower than its low temperature threshold in internal environment, can star heating and adjusts.Hence for of short duration heat interference, will not lead
It causes temperature adjusting start and stop frequent, can reduce energy consumption.
Likewise, the present invention is overcome using following methods for cold interference, as shown in Figure 3,4, ambient temperature is judged
>=Teh, then interior environment temperature adjusting only allow to freeze, and interior environment temperature >=Tch, interior environment temperature adjusts starting system
It is cold, until interior environment temperature < Tch, stops interior environment temperature and adjusts；Interior environment temperature≤Tcl, interior environment temperature
Adjusting does not start heating still, and Tcl < interior environment temperature < Tch, interior environment temperature adjusting does not start refrigeration and heating is internal
Portion's environment temperature is adjusted.The program not will lead to temperature adjust start and stop it is frequent, can reduce energy consumption.Likewise, for cold interference,
Suitable for use of the above-mentioned comparative example and embodiment this programme, and temperature reaches such as 10 DEG C outside library, and cold interference is -7 DEG C,
Above scheme, the present invention according to be presently in library external environment high temperature, library external environment low temperature, then to environment in library
Temperature is freezed or heats adjusting, and the hot environment outside library is only capable of realizing that environment temperature reaches a high temperature threshold in library so that controlling
Value and freeze, no matter whether environment temperature reaches low temperature threshold in current library, does not heat；Low temperature environment outside library is only capable of making
It must control and realize that environment temperature reaches low temperature threshold and heats in library, no matter whether environment temperature reaches a high temperature threshold in current library
Value, does not freeze.To supplement heat interference using environment temperature, and do not lead to environment in library in library when external environment high and low temperature
Unwanted refrigeration or heating are generated, can't be higher or lower because of environment temperature, so that existing control strategy is unable to control
Because unwanted temperature caused by interfering is adjusted.
Tel < ambient temperature < Teh of the invention is then adjusted according to internal environment observed temperature: internal environment temperature
Degree≤Tcl, interior environment temperature adjusts starting heating, until interior environment temperature > Tcl, stops interior environment temperature and adjust；
Interior environment temperature >=Tch, interior environment temperature adjusts starting refrigeration, until interior environment temperature < Tch, stops internal environment
Temperature is adjusted；Tcl < interior environment temperature < Tch, interior environment temperature adjusting do not start refrigeration and heating；Only in external rings
In the case of border is suitable for, refrigeration caused by interfering or heating, external environment can't aggravate it, thus interior environment temperature tune
Straightening connects to be judged according to its monitoring temperature and threshold value, meets with interference, is impacted and not as good as portion's environment temperature mistake outside
High or too low is relatively strong.
It in one embodiment, is internal high temperature threshold value for Tch, Tcl is inner cryogenic threshold value, and setting temperature controls back
Cha ⊿ t, temperature range are 0.3~0.7 DEG C, and Tch- ⊿ t is actual inside high temperature threshold value, and Tcl- ⊿ t is real inner cryogenic threshold
Value, touches actual inside temperature threshold in interior environment temperature threshold value, then the corresponding refrigeration of starting or heating, and effect is: temperature
Control return difference is the temperature return difference of temperature control high temperature threshold values (TcH) and temperature control low temperature threshold values (TcL), since temperature has
Inertia, when preventing from stopping because heating or freezing, product temperature continues to heat up or cool down, to keep temperature high beyond temperature control
Warm threshold values (TcH) or temperature control low temperature threshold values (TcL) cause heating refrigeration alternately frequent starting, cause the waste of the energy and set
The reduction of standby service life.
In one embodiment, as shown in figure 5, implementing the system of the temprature control method comprising condenser, evaporation

Storehouse temperature.Temperature controls back the temperature that difference ⊿ T is temperature control high temperature threshold values (TcH) and temperature control high temperature threshold values (TcL)
Return difference, since temperature has inertia, when preventing from stopping because heating or freezing, product temperature continues to heat up or cool down, to make
Temperature causes heating refrigeration alternately frequent starting beyond temperature control high temperature threshold values (TcH) or temperature control low temperature threshold values (TcL),
Cause the waste of the energy and the reduction of service life of equipment.
Using ptc heater, can arrive following effect: 1) surface temperature is low, and thermostatic characteristics are good, the thermal efficiency is high drops
