It is specifically a kind of to be directed to the higher indirect refrigeration system of safety too the present invention relates to freezer defrosting device field Positive energy defrosting system for refrigeration house.
Background technology
Freezer defrosting at present generally uses following three kinds of modes, when manually defrost, it is direct using defrosting tool by worker Defrosting, labour cost is high and defrosting efficiency is poor, second is that high pressure gas defrost, defrosting effect is good, but because being high pressure gas, exists Security risk;Third, using electric heater defrosting, simple system is easy to operate, but all to there is power consumption excessive for second and third kind of method, High energy consumption and have the shortcomings that the danger such as to leak, catch fire, there are severe compromises.
Invention content
Technical problem to be solved by the invention is to provide a kind of solar energy freezer defrostings suitable for indirect refrigeration system System, to solve defect existing in the prior art.
The technical solution that the present invention solves above-mentioned technical problem is as follows:
A kind of solar energy defrosting system for refrigeration house suitable for indirect refrigeration system, including solar control cabinet (4) and difference Coupled solar thermal collector (1), heat preservation liquid reserve tank (2), refrigeration unit (3), defrosting feed flow valve (7), collection thermal cycle (8), liquid level sensor (9) and liquid inlet electromagnetic valve (10) are pumped, the solar thermal collector (1) and heat preservation liquid reserve tank (2) pass through collection Hot recycle pump (8) controls the circulation of liquid, and the freezer refrigerating comb (3) and heat preservation liquid reserve tank (2) pass through defrosting feed flow valve (7) circulation of liquid between the two is controlled, the freezer refrigerating comb (3) connect with refrigeration unit (3);Solar thermal collector (1) when temperature is higher than 5 DEG C of liquid reserve tank (2) temperature of heat preservation, solar control cabinet (4) domination set hot recycle pump (8) is opened, heat by Solar thermal collector (1) is transferred to heat preservation liquid reserve tank (2) through liquid circulation;Solar thermal collector (1) temperature is higher than heat preservation liquid storage When 2 DEG C of case (2) temperature, solar control cabinet (4) domination set hot recycle pump (8) is closed, stop liquid flowing;When defrosting, the sun Energy switch board (4) closes refrigeration unit (3), opens defrosting feed flow valve (7), and heat preservation liquid reserve tank (2) liquid flows into freezer refrigerating Comb (3) carries out defrosting, and then liquid returns to heat preservation liquid reserve tank (2), after defrosting, solar energy control through defrosting liquid back pipe (6) Cabinet (4) processed closes defrosting feed flow valve (7), opens refrigeration unit (3) and freezes;
Further, it is provided with liquid level sensor (9) in the heat preservation liquid reserve tank (2), when liquid level is less than setting value, too Positive energy switch board (4) controls liquid inlet electromagnetic valve (10) and opens, and supplements heat preservation liquid reserve tank (2) interior refrigerating medium;
Further, the solar control cabinet (4) shows heat preservation liquid reserve tank (2) temperature, liquid level, the sun by liquid crystal display It can heat collector liquid temperature, collection hot recycle pump state and liquid inlet electromagnetic valve state.
The beneficial effects of the invention are as follows:Solar energy is utilized when defrosting, is not required to open refrigeration host computer, is saved a large amount of electricity Can, and system works under normal pressure, ensures safety, meets environmental requirement.
