Description

Self-cleaning refrigeration system suitable for refrigerated display cabinet
Technical field
The present invention relates to refrigerated display cabinet refrigeration system, and freezing more particularly, to the self-cleaning suitable for refrigerated display cabinet is System.
Background technology
As requirement more and more higher of the people to quality of the life, food-safe attention, the use of refrigerated display cabinet are got over Come more frequent.Finned cooler is commonly utilized in refrigerated display cabinet because efficient heat exchange efficiency.Condenser is mostly to inhale Wind radiates, and spacing of fin is smaller(Generally in 2mm or so), during long-term uses, the foreign matters such as dust are easily adsorbed, are caused Condenser impaired heat exchange efficiency, even can be completely plugged when serious;Condenser radiating is not smooth, easily causes compressor damage, stops The problems such as machine.In order to prevent refrigerated display cabinet fin condenser from blocking, it is at present more take installed additional before fin condenser it is dust-proof The mode of filter screen solves, but the dustproof filter screen installed additional needs periodically artificial cleaning, and this just gives refrigerated display cabinet daily management band Carry out inconvenience, cause compressor damage because user does not carry out periodic cleaning on request, shut down phenomenon and happen occasionally, to making User causes economic loss, while also reduces the security of food in refrigerated display cabinet.
The content of the invention
Present invention aims at provide a kind of self-cleaning refrigeration system suitable for refrigerated display cabinet.
To achieve the above object, the present invention takes following technical proposals:
Self-cleaning refrigeration system of the present invention suitable for refrigerated display cabinet, including refrigeration compressor, the refrigeration compressor row Gas port and fiber tube heat exchanger inlet communication, the fiber tube heat exchanger exit are divided into two-way, pass through the first magnetic valve and fin all the way Formula condenser inlet connect, another way by after the first capillary-compensated with the finned cooler inlet communication;It is finned Condensator outlet is divided into two-way, all the way by connecting after the second capillary-compensated with the evaporator being arranged in refrigerated display cabinet Logical, another way is connected by second solenoid valve with refrigeration compressor air suction mouth;The evaporator outlet and refrigeration compressor air suction Mouth connection.
The invention has the advantages that realizing the automatic dust removing cleaning of refrigerated display cabinet finned cooler, it is finned to reach raising Condenser heat exchanger effectiveness, prevent the refrigeration compressor damage purpose caused by cold finned condenser radiating is not smooth.
Brief description of the drawings
Fig. 1 is the schematic diagram of refrigeration work state of the present invention.
Fig. 2 is the schematic diagram of self-cleaning working condition of the present invention.
Fig. 3 is electric-control system schematic diagram of the present invention.
Embodiment
Embodiments of the invention are elaborated below in conjunction with the accompanying drawings, the present embodiment using technical solution of the present invention before Put and 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 Figure 1-2, the self-cleaning refrigeration system of the present invention suitable for refrigerated display cabinet, including refrigeration compressor 1, The exhaust outlet of refrigeration compressor 1 and the inlet communication of fiber tube heat exchanger 2, the outlet of fiber tube heat exchanger 2 are divided into two-way, a-road-through Cross the first magnetic valve 3 and the inlet communication of finned cooler 4, another way throttled by the first capillary 5 after with it is described finned The inlet communication of condenser 4;Finned cooler 4 outlet is divided into two-way, all the way by the second capillary 6 throttle after be arranged on it is cold The inlet communication of evaporator 7 in showcase is hidden, another way is connected by second solenoid valve 8 with the air entry of refrigeration compressor 1;It is described The outlet of evaporator 8 connects with the air entry of refrigeration compressor 1.
Operation principle of the present invention is summarized as follows:
As shown in Figure 1,3, during refrigeration work, power switch KM1, power switch KM2 and refrigeration switch K1 closures, refrigeration compressor 1st, condensation fan 9 works, at the same relay KA obtain it is electric, relay KA open contacts Ka1 closure and normally-closed contact Ka2 disconnects, First magnetic valve 3 is opened, and second solenoid valve 8 is closed;Now, as shown in figure 1, being arranged from the exhaust outlet of refrigeration compressor 1 The high temperature and high pressure steam gone out is changed into highly pressurised liquid after being condensed by fiber tube heat exchanger 2, the first magnetic valve 3 and finned cooler 4, It is changed into low-temperature low-pressure refrigerant after the second capillary 6 into the evaporator 7 in refrigerated display cabinet, to the food in refrigerated display cabinet Thing carries out heat exchange, carries out next circulation into refrigeration compressor 1 after endothermic gasification;Said process is that refrigerated display cabinet is normal Process of refrigerastion, because the first magnetic valve 3 is opened, play and act on the bypass of the first capillary 5, so the first capillary 5 not work Make, i.e., do not play throttling action.
When finned cooler 4 because absorption dust is excessive, cause impaired heat exchange efficiency, radiating not smooth and cause refrigeration system During hypertonia of uniting, votage control switch P is acted, relay KA dead electricity, and relay KA open contacts Ka1 disconnects and normally-closed contact Ka2 close, now, as shown in Fig. 2 from the exhaust outlet of refrigeration compressor 1 discharge high temperature and high pressure steam by fiber tube heat exchanger 2, Enter finned cooler 4 after the throttling of first capillary 5, the now absorption of finned cooler 4 heat plays evaporator effect, will Humid air and dust, which condense, on finned cooler 4 is changed into muddy water and ice, under gravity from the supernatant of finned cooler 4 Remove;From finned cooler 4 export the gasification steam that ejects carried out into refrigeration compressor 1 by second solenoid valve 8 it is next Individual circulation;In said process, because second solenoid valve 8 is opened, play and act on the bypass of the second capillary 6, so the second capillary Pipe 6 does not work, i.e., does not play throttling action.
After the time of setting is reached, as shown in Figure 1,3, the normal process of refrigerastion of refrigerated display cabinet is returned to, it is finned Condenser 4 is operated in heat release state, and it is ice melting and remove to condense on finned cooler 4 dust-laden left, so as to reach To the automatic cleaning purpose to refrigerated display cabinet finned cooler 4
Because spacing is big absorption dust etc. will not occur in refrigerated display cabinet normal work for the fin of wire tube condenser 2 Foreign matter causes impaired heat exchange efficiency phenomenon.
