Abstract
The invention provides a defrosting control method of an indirect cool refrigerator, belonging to the field of refrigeration. The invention gives a defrosting period with different time spans by judging ambient temperature according to cold storage door opening times within one hour; the defrosting period is compared with the operating defrosting period at present to choose the shorter defrosting period to perform, thus defrosting until reaching defrosting reset temperature. The control method of the invention can adopt different defrosting periods according to different states of the refrigerator; during high load, a shorter defrosting period is adopted so as to reduce the problem of unfavourable defrosting; during low load, a longer defrosting period is adopted to reduce unnecessary energy consumption.
Description
Technical field
The invention belongs to refrigerating field, relate to indirect cool refrigerator, especially its defrosting control method.
Background technology
The defrosting of indirect cool refrigerator judgement at present decides according to the compressor Cumulative Elapsed Time, the time interval between per twice defrosting of most of indirect cool refrigerators is identical, consequent problem is: if environment temperature changes, perhaps door opening times difference, or the case internal burden changes, and the frosting state on the evaporimeter is different.Appropriate iff judging according to fixing compressor Cumulative Elapsed Time whether defrosting owes.Such as, under the bigger condition of extraneous temperature and humidity, it is more frequent to open the door, it is more that hot gas is invaded, on the evaporimeter with regard to easy frost, if the defrosting cycle of also press under the general condition is controlled, if it is oversize at interval between twice defrosting, once change endless, tied a lot of frosts again next time before changing, it is bad just to be easy to generate defrost; And it is lower to work as environment temperature, and it is less to load, and when the compressor operation rate is lower, if very short at interval between twice defrosting, tends to produce unnecessary defrosting consumed energy.
Summary of the invention
The object of the present invention is to provide a kind of defrosting control method of indirect cool refrigerator, both can prevent that defrost is bad, can reduce the energy that unnecessary defrosting running consumes again.
For reaching above purpose, solution of the present invention is:
A kind of defrosting control method of indirect cool refrigerator, it may further comprise the steps: judge to draw defrosting cycle; Confirm whether to satisfy defrosting beginning condition; Defrost and stop defrosting until reaching the defrosting reset temperature.
Defrosting cycle comprises high capacity pattern CASE1, general modfel CASE2, power consumption pattern CASE3.
High capacity pattern CASE1 is that defrosting cycle is the shortest, and when environment temperature is higher than 33 ℃, and cold sotrage door opens the door once and adopts this kind pattern when above.
General modfel CASE2 defrosting cycle is longer than CASE1, and when environment temperature is higher than 33 ℃, cold sotrage door was not opened; Perhaps environment temperature is in 32 ℃ ~ 28 ℃; Perhaps environment temperature is in 27 ℃ ~ 23 ℃, more than cold sotrage door opens the door once; Adopt this kind pattern when perhaps environment temperature is lower than 22 ℃.
Power consumption pattern CASE3 defrosting cycle is longer than CASE2, when environment temperature is in 27 ℃ ~ 23 ℃, adopts this kind pattern when cold sotrage door does not open the door.
The operation of power consumption pattern CASE3 must satisfy power on for the first time and defrost after compressor have 2 times the start after.
Defrosting cycle judges according to input environment temperature and the cold sotrage door door opening times of each hour with hour as judgment standard, with the shortest detected defrosting cycle as the defrosting cycle judged result.
Defrosting beginning condition is for confirming whether defrosting cycle exists periodic change, and the priority of defrosting cycle is CASE1〉CASE2〉CASE3, contrast the defrosting cycle of current employing and defrosting cycle that judgement draws and adopt the high pattern of priority to defrost.
Owing to adopted such scheme, the present invention has following characteristics: the present invention is directed to different external condition and adjust defrosting cycle, when refrigerator is under the more abominable hot environment or during in heavy-duty service, adopts short defrosting cycle, can reduce the bad danger of defrost; Under the underload service condition, prolong defrosting cycle accordingly, also can reduce the energy consumption that unnecessary defrosting running consumes, and cold phenomenon a little less than the refrigerator that has prevented from being brought by unnecessary defrosting running.
The specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
A kind of defrosting control method of indirect cool refrigerator comprises according to current external condition and running status and carries out the judgement of defrosting cycle; Determine whether to satisfy defrosting beginning condition; If satisfy defrosting beginning condition, then the electrical heating operation defrosts, and reaches the defrosting reset temperature up to the temperature of defrosting sensor and namely stops defrosting.The judgement of defrosting cycle is to decide with environment temperature, refrigerating chamber door opening times, according to different combination conditions, carries out different CASE (CASE is compressor accumulated running time).
Concrete defrosting cycle is judged the according to the form below execution
The time of each CASE is compressor accumulated running time.
Wherein, CASE1 is the high capacity pattern, and namely environment temperature is higher, and the cold sotrage door switch is situation frequently.At this moment, the hot gas of being invaded refrigerating chamber by inner air channel is more, easy frost on the freezer evaporator, and defrosting cycle is set to lack most in this case, strives for repeatedly defrost, prevents residual frost accumulation
CASE2 is general modfel, i.e. situation under the analog subscriber regular service conditions.
CASE3 is the power consumption pattern, and namely normally ring is down warm, and the user does not open the low load condition of refrigerator doors, is the electric weight that reduces owing to defrosting consumption, and the defrosting cycle of length is set.
When defrosting cycle is judged, according to per hour input environment temperature and cold sotrage door door opening times are come fixed CASE hourly.That is, defrosting cycle CASE was that unit is judged with 1 hour.
Defrosting cycle is that benchmark is carried out by the shortest CASE of cycle among the detected CASE per hour.
The priority condition of each CASE is CASE1〉CASE2〉CASE3, namely because CASE changes, defrosting cycle is subject to variation and is shorter defrosting cycle, if determined the defrosting cycle time after changing, CASE carries out defrosting immediately when judging end.
The time of adopting is that CASE1 is 4 hours at present, and CASE2 is 6 hours; CASE3 is 26 hours, can finely tune to reach Best Times according to actual conditions by program and distinguish.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
