Description
Technical field
The utility model is related to refrigerated display cabinet refrigeration systems, more particularly, to the self-cleaning refrigeration suitable for refrigerated display cabinet
System.
Background technology
Requirement with people to quality of the life is higher and higher, and the use of food-safe attention, refrigerated display cabinet is got over
Come more frequent.Finned cooler is commonly utilized in because of efficient heat exchange efficiency in refrigerated display cabinet.Condenser is mostly to inhale
Wind radiates, and spacing of fin is smaller（Generally in 2mm or so）, in the long-term use, the foreign matters such as absorption dust are easy, are caused
Condenser impaired heat exchange efficiency, even can be completely plugged when serious；Condenser heat dissipation is unsmooth, easily causes compressor damage, stops
The problems such as machine.Refrigerated display cabinet fin condenser blocks in order to prevent, it is at present more take installed additional before fin condenser it is dust-proof
The mode of strainer needs periodically artificial cleaning come the dustproof filter screen for solving, but installing additional, this just gives refrigerated display cabinet daily management band
Carry out inconvenience, leads to compressor damage because user does not carry out periodic cleaning as required, shuts down phenomenon and happen occasionally, to making
User causes economic loss, while also reducing the safety of food in refrigerated display cabinet.
Invention content
The utility model aim is to provide a kind of self-cleaning refrigeration system suitable for refrigerated display cabinet.
To achieve the above object, the utility model takes following technical proposals：
Self-cleaning refrigeration system described in the utility model suitable for refrigerated display cabinet, including refrigeration compressor, the refrigeration
Exhaust outlet of compressor and fiber tube heat exchanger inlet communication, the fiber tube heat exchanger exit are divided into two-way, pass through the first electromagnetism all the way
Valve and finned cooler inlet communication, another way after the first capillary-compensated with the finned cooler import by connecting
It is logical；Finned cooler outlet is divided into two-way, all the way by after the second capillary-compensated with the steaming that is arranged in refrigerated display cabinet
Device inlet communication is sent out, another way is connected to by second solenoid valve with refrigeration compressor air suction mouth；The evaporator outlet and refrigeration
Compressor air suction mouth is connected to.
The utility model advantage is to realize that the automatic dust removing of refrigerated display cabinet finned cooler is cleared up, and reaches raising wing
Chip type condenser heat exchanger effectiveness prevents the refrigeration compressor caused by cold finned condenser heat dissipation is unsmooth from damaging purpose.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model refrigeration work state.
Fig. 2 is the schematic diagram of the utility model self-cleaning working condition.
Fig. 3 is the utility model electric-control system schematic diagram.
Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figs. 1-2, the self-cleaning refrigeration system described in the utility model suitable for refrigerated display cabinet, including refrigerant compression
Machine 1,1 exhaust outlet of the refrigeration compressor and 2 inlet communication of fiber tube heat exchanger, the fiber tube heat exchanger 2, which exports, is divided into two-way, and one
Road by the first solenoid valve 3 and 4 inlet communication of finned cooler, another way throttled by the first capillary 5 after with the wing
4 inlet communication of chip type condenser；Finned cooler 4 outlet is divided into two-way, all the way by the second capillary 6 throttle after with setting
7 inlet communication of evaporator in refrigerated display cabinet, another way are connected to by second solenoid valve 8 with 1 air entry of refrigeration compressor；
The outlet of the evaporator 8 is connected to 1 air entry of refrigeration compressor.
Utility model works principle is summarized as follows：
As shown in Figure 1,3, when refrigeration work, power switch KM1, power switch KM2 and refrigeration switch K1 are closed, refrigeration pressure
Contracting machine 1, condensation fan 9 work, while relay KA obtains electric, and the open contacts Ka1 of relay KA is closed and normally-closed contact Ka2 is disconnected
It opens, the first solenoid valve 3 is opened, and second solenoid valve 8 is closed；At this point, as shown in Figure 1, from 1 exhaust outlet of refrigeration compressor
The high temperature and high pressure steam of discharge becomes high pressure liquid after being condensed by fiber tube heat exchanger 2, the first solenoid valve 3 and finned cooler 4
Body becomes the evaporator 7 that low-temperature low-pressure refrigerant enters in refrigerated display cabinet, in refrigerated display cabinet after the second capillary 6
Food carry out heat exchange, carry out next cycle into refrigeration compressor 1 after endothermic gasification；The above process is refrigerated display cabinet
Normal process of refrigerastion plays the role of 5 bypass of the first capillary, since the first solenoid valve 3 is opened so the first capillary 5
It does not work, i.e., does not play throttling action.
When finned cooler 4 since absorption dust is excessive, impaired heat exchange efficiency is caused, heat dissipation is unsmooth and leads to refrigeration system
When hypertonia of uniting, votage control switch P actions, the open contacts Ka1 of relay KA dead electricity, relay KA is disconnected and normally-closed contact
Ka2 be closed, at this point, as shown in Fig. 2, from 1 exhaust outlet of refrigeration compressor be discharged high temperature and high pressure steam by fiber tube heat exchanger 2,
Enter finned cooler 4 after the throttling of first capillary 5, the heat of the absorption of finned cooler 4 at this time plays the role of evaporator, will
Humid air and dust condensation become muddy water and ice on finned cooler 4, under the effect of gravity from 4 supernatant of finned cooler
It removes；The gasification steam ejected from the outlet of finned cooler 4 is carried out by second solenoid valve 8 into refrigeration compressor 1 next
A cycle；In the above process, since second solenoid valve 8 is opened, play the role of 6 bypass of the second capillary, so the second capillary
Pipe 6 does not work, i.e., does not play throttling action.
After reaching the time of setting, as shown in Figure 1,3, it is restored to the normal process of refrigerastion of refrigerated display cabinet, it is finned
Condenser 4 is operated in heat release state, and it is ice melting and remove to condense in the dust-laden left on finned cooler 4, to reach
To the automatic cleaning purpose to refrigerated display cabinet finned cooler 4
Since spacing is big absorption ash will not occur when refrigerated display cabinet works normally for the fin of wire tube condenser 2
The foreign matters such as dirt lead to impaired heat exchange efficiency phenomenon.
