Abstract
A defroster for refrigerating system has an electromagnetic valve and electrothermal element installed to one pipeline that is parallelly connected to both ends of throttling device. When the defroster is turned on, the refrigerant in refrigerating system flows in unobstructed mode, so not playing its refrigeration role, and is heated by electrothermal element to defrost.
Description
The present invention relates to a kind of by magnetic valve, pipeline, a kind of defroster that is used for refrigeration system that heating and power switch are formed.Especially by the throttling device two ends that are loaded in the refrigeration system, a kind of defroster that gas circuit is in parallel with the throttling device.
Refrigerator, the refrigeration system of refrigerator-freezer and freezer etc. can seriously freeze after having moved a period of time, influence refrigerating efficiency and access goods.Remove the process of these ice-cold nominal meaning defrostings, normally adopt forced stoppage, wait for from changing.Nominal has the temperature controller of defrost function, in fact only be a kind of time-delay or hand switch in action.In some small refrigerator freezer machine heating wire is housed, they all are tool portions, the evaporimeter position heating wire of can not packing into.On the contrary can not electrical heating in the position that needs most defrost ice.People take out goods in order to be eager, often take to pound, and the method for sled, in the refrigeration system maintenance, it is the most common damaging the evaporimeter refrigeration pipe, one of the most serious fault.
The purpose of this invention is to provide a kind of defroster that is used for refrigeration system, its defroster can defrost to former refrigeration position heatingization ice.
In order to achieve the above object, the present invention has adopted magnetic valve, it is introduced in the refrigeration air-channel system with pipeline, in parallel with throttling device gas circuit, on the electromagnetic valve outlet pipeline, heating is housed, under the situation of refrigeration system operation, closed its defroster power switch, cold-producing medium is heated from the electromagnetic valve outlet pipeline, and the band hot-fluid has carried out the defrosting of change ice through former refrigeration position to this position.
A kind of advantage that is used for the defroster of refrigeration system of the present invention is: (1) is simple in structure; (2) utilize not refrigerating operaton of former cold-producing medium band temperature, act on former refrigeration position, it is rapid, energy-conservation to change ice.
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
Accompanying drawing is the refrigeration system schematic diagram that defroster of the present invention is housed.
As seen from the figure, defroster of the present invention is by magnetic valve 5, admission line 7, and outlet conduit 8, heating 6 and power switch 9 formed, and the admission line 7 of magnetic valve is that the joint location at condenser 2 and throttling device 3 inserts.The embodiment of accompanying drawing has provided the schematic diagram that a kind of capillary is a flow controller, other kind principles are identical, the outlet pipe 8 of magnetic valve 5 has inserted the joint location of throttling device 3 and evaporimeter 4, and frost removal of the present invention like this with throttling device 3 is in parallel on gas circuit.
By accompanying drawing as can be known, when the power switch 9 of defroster disconnected, closed electromagnetic valve, heating were also in off working state.Start refrigeration system this moment, cold-producing medium is extruded by compressor 1, the condenser 2 of flowing through, closed electromagnetic valve at this moment, cold-producing medium can only be finished process of refrigerastion by flowing to evaporimeter 4 through the piping back pressure machine 1 that contracts from throttling device 3, when need defrost, closed power switch 9, this moment magnetic valve with opened one by the new tunnel shown in the double-head arrow 7, magnetic valve 5, pipeline 8 passes through, and throttling device 3 loses throttling action, and is heated by heating 6 on pipeline 8.This moment, cold-producing medium did not freeze, and the flow through pipeline of evaporimeter 4 of band heat defrosts with institute's heat ice of being with, and flows back to compressor 1.
The power switch 9 of frost removal of the present invention can also be subjected to temperature measuring head and be contained in temperature controller control on the pipeline 12, when temperature rise is higher, turns off power switch 9 after promptly defrosting finishes.
Frost removal of the present invention can also install device for drying and filtering 11 additional for 7 sections at pipeline, and air flow purifies cold-producing medium when utilizing defrosting.
Frost removal of the present invention can also carry out compressor 1 separately to magnetic valve 5 and start preceding several seconds conducting control.Can before starting, compressor 1 discharge the refrigeration system high pressure lateral pressure like this.Protection compressor 1 is not with to press and is started.The device of slow startup protector was simple than several minutes like this, and is reliable, saves time.
Claims (4)
1, a kind of defroster that is used for refrigeration system, it comprises magnetic valve 5, pipeline 7,8, heating 6 and power switch 9, the two ends pipeline of the restricting element 3 in the two ends that it is characterized in that its pipeline 7,8 and the refrigeration system is connected.
2,, it is characterized in that its power switch 9 is subjected to temperature measuring head to be contained in the temperature controller 10 control defrosting times of evaporator pipeline outlet according to the defroster of claim 1.
3, according to the defroster of claim 1, it is characterized in that its power of electromagnetic valve is connected to a time-delay relay 13, and be connected that when starting refrigeration system, it is kept and opens the magnetic valve several seconds with the refrigeration system electric starting system, discharge the high-pressure side overbottom pressure.
4, according to claim 1,2,3 defroster, it is characterized in that on its pipeline 7,8 device for drying and filtering 11 being housed, the dry filter process is carried out outside system in advance.
