Description
Technical field
The utility model relates to refrigeration equipments, more particularly, to a kind of air curtain cabinet energy-saving operation system.
Background technique
The also referred to as vertical wind cabinet of air curtain cabinet, is common in supermarket, fruit shop etc., shows or for cooking fruit as low-temperature milk refrigeration
Cabinet.When refrigeration cold air from back blow out, uniformly cover to each corner in cabinet, reach internal product is carried out it is fresh-keeping
Purpose.Since air curtain cabinet is open type design, there is no glass door to be closed before cabinet body, it is very convenient that customer fetches article, makes
Dosage is also increasing.
With the extensive application of air curtain cabinet, power consumption and electric cost are higher and higher, user to air curtain cabinet energy conservation and
The requirement for reducing electric energy use cost is also higher and higher.Existing air curtain cabinet reduces there are two ways to energy consumption: one is at night
Curtain of night curtain is pulled on when use, and hot air outside cold air and cabinet is completely cut off in cabinet by curtain of night curtain, heat exchange is reduced, reduces refrigerator
Thermic load, to reduce energy consumption；But although pulling on curtain of night curtain thermic load reduces, blower and compressor are also with volume
Determine rotation speed operation, refrigerating capacity is essentially unchanged, therefore electric energy use cost is too many again without reducing.Another kind is in air curtain cabinet
Night energy-saving mode is added on refrigeration unit, by temperature controller set period of time, timing controlled air curtain cabinet is in night starting energy-saving
Mode, blower and the operation of compressor low speed during this period of time, to reach energy saving purpose；But not due to the business hours at night
It is very fixed, therefore usually needs to change the period set, the artificial change for carrying out parameter, due to needing frequently more
Change timing section, causes very big inconvenience again to the use of user.
Summary of the invention
The utility model aim is to provide a kind of structure simple, air curtain cabinet energy-saving operation system easy to operate.
To achieve the above object, the utility model can take following technical proposals:
Air curtain cabinet energy-saving operation system described in the utility model, including the curtain of night curtain being installed on air curtain cabinet, Yi Jiyou
Condensation fan, evaporation fan and the compressor by Frequency Converter Control of temperature controller control are arranged in the lower pull end of the curtain of night curtain
There is buckle compatible with the hook on the air curtain cabinet；It is characterized by: being provided with signal detection mould in the temperature controller
Block and PLC controller, the signal input part of the PLC controller are electrically connected with the signal output end of the signal detection module；
It is provided on the air curtain cabinet close to the hook position close to switch, the signal output end and the signal close to switch
The signal input part of detection module is electrically connected；It is provided on the curtain of night curtain of the snapped-in position compatible with close to switching
Induced magnet；The temperature controller and condensation fan, evaporation fan tick-over circuit in be in series with controlled by temperature controller respectively
The normally opened contact of the slow-speed relay of on-off.
The utility model advantage is that structure is simple, easy to operate.Without timing or other operation bidirectionals, only pass through the curtain of night
Curtain pulls down and packs up the switching for being just able to achieve air curtain cabinet between energy conservation and specified operation double mode, to change blower and pressure
Contracting machine revolving speed reduces the power consumption at air curtain cabinet night, reduces use cost.Due to using without considering the problems of the business hours
Family use is more convenient.
Detailed description of the invention
Fig. 1 is the circuit diagram of the utility model.
Fig. 2 is the workflow block diagram of the utility model.
Specific embodiment
As shown in Figure 1, air curtain cabinet energy-saving operation system described in the utility model, including the curtain of night being installed on air curtain cabinet
Curtain 1, and the condensation fan 3, the evaporation fan 4 and by the compressor 5 of Frequency Converter Control that are controlled by temperature controller 2, in curtain of night curtain 1
Lower pull end is provided with buckle 7 compatible with the hook 6 on air curtain cabinet；2.1 He of signal detection module is provided in temperature controller 2
The signal input part of PLC controller 2.2, PLC controller 2.2 is electrically connected with the signal output end of signal detection module 2.1；It is leaning on
It is provided on the air curtain cabinet of 6 positions of nearly hook close to switch 8, close to signal output end and the signal detection module 2.1 of switch 8
Signal input part electrical connection；Induced magnet 9 compatible with close switch 8 is provided on the curtain of night curtain 1 of 7 positions of buckle；
Temperature controller 2 and condensation fan 3, evaporation fan 4 tick-over circuit in be in series with respectively by the low of temperature controller control on-off
The normally opened contact 10 of fast relay.
The workflow of the utility model is as shown in Figure 2:
When air curtain cabinet works normally, curtain of night curtain 1 is packed up, and condensation fan 3, evaporation fan 4 are operated with normal speed, air curtain cabinet
In specified operational mode；
When night's rest or when not doing business, curtain of night curtain 1 is pulled down, the buckle 7 of the lower pull end of curtain of night curtain 1 is stuck in the extension on air curtain cabinet
On hook 6, the signal of induced magnet 9 is transmitted to temperature close to switch 8 close proximity to switch 8 by the induced magnet 9 on curtain of night curtain 1 at this time
The signal detection module 2.1 of device 2 is controlled, after signal detection module 2.1 receives signal, (delay time could in 3 ~ 5 minutes for automatic time delay
To be configured by PLC controller 2.2), if signal detection module 2.1 3 ~ remain to receive the signal after five minutes,
Temperature controller 2 controls the normally opened contact 10 for the slow-speed relay being connected on the tick-over circuit of condensation fan 3 and evaporation fan 4
Conducting, condensation fan 3 and evaporation fan 4 enter low-speed operation mode simultaneously, and compressor 5 is then changed by frequency converter according to thermic load
Automatic speed regulation, air curtain cabinet is in energy conservation model at this time.
If curtain of night curtain 1 is packed up in 3 ~ 5 minutes, do not enter energy-saving mode.
After energy-saving mode runs a period of time, if packing up curtain of night curtain 1, induced magnet 9 is left close to switch 8, close to open
It closing 8 and does not transmit signal to the signal detection module 2.1 of temperature controller 2, temperature controller starts timing certain time at this time, and such as 3 ~ 5 minutes,
If after timing, curtain of night curtain 1 or collapsed state, the i.e. signal detection module 2.1 of temperature controller are not received close to switch 8
Signal, then energy-saving mode terminates, and into specified operational mode, temperature controller 2 controls the normally opened touching of the slow-speed relay of blower low speed
Point 10 disconnects, and condensation fan 3 and evaporation fan 4 are operated with normal speed, and compressor 5 is then changed certainly by frequency converter according to thermic load
Dynamic speed regulation；If curtain of night curtain 1 pulls down in timing time again, temperature controller signal detection module is delivered a signal to close to switch 8
2.1, then air curtain cabinet is in energy-saving mode.
In actual use, the utility model is not limited to structure described in text, and induced magnet 9 is such as replaced with stroke and is opened
It closes, while being replaced with position sensor close to switch 8, equally can realize air curtain cabinet by the closure and unlatching of curtain of night curtain 1
Switching between energy conservation and specified double mode.
