The refrigeration system combines the advantages of an air cooling system and a direct cooling system and has high efficiency, rapid cooling and small energy consumption, which can easily save energy and has good effect in food cold storage and preservation.
Description
Technical field
The utility model relates to the refrigerator technical field, specifically is a kind of refrigeration system of frost-free refrigerator.
Background technology
Existing fridge-freezer generally all is to adopt the direct-cooled system that includes refrigeration evaporator and refrigerating evaporator, just usually said direct cooling refrigerator separately; Or comprise the air cooling system of evaporator fin, just usually said wind cooling refrigerator or claim frost-free refrigerator.The shortcoming that wherein direct-cooled system exists is: (1) single refrigerating chamber cooling rate is slow, is unfavorable for food such as meat fast by the ice crystal band, and fresh keeping property is general; (2) system is after operation a period of time, and the interior frosting of refrigerating chamber is serious, influences the heat exchange efficiency of evaporimeter; (3) can only rely on the shutdown defrost, the frost layer is difficult for removing.And the shortcoming that air cooling system exists is: (1) running noise is big; (2) energy consumption is bigger, and is energy-conservation inadequately; (3) foodstuff storing moisture content runs off soon, and easily air-dry, the fresh-keeping effect of food is poor.
The utility model content
The purpose of this utility model is the refrigeration system that the shortcoming that overcomes above-mentioned prior art provides a kind of frost-free refrigerator in conjunction with air cooling system and direct-cooled system advantage, its operational efficiency height, cooling fast, energy consumption is little, be easy to energy-conservation, and the refrigeration of food and good refreshing effect.
The technical solution of the utility model is: a kind of refrigeration system of frost-free refrigerator, comprise the refrigerating system that is provided with refrigeration evaporator, the refrigeration system that is formed in parallel by evaporator fin and refrigerating evaporator, comprise that also the conversion equipment that refrigeration system, refrigerating system open and close is separately changed and realized to evaporator fin and refrigerating evaporator mutually in the refrigeration system, and control conversion equipment master board, wherein refrigerating system and refrigeration system and connect the back with compressor, condenser be connected to form the closure refrigerating circuit.
Above-mentioned refrigerating system and refrigeration system are connected in parallel.
Above-mentioned conversion equipment is a magnetic valve.
The feedback temperature signal that above-mentioned master board receives derives from refrigerating chamber temperature-sensitive head, refrigerating chamber temperature-sensitive head and door switch signal.
The running of above-mentioned refrigeration system is: the beginning of household refrigerator-freezer energising refrigeration, control the evaporator fin work that allows earlier by master control borad, realize the refrigerating chamber fast cooling, remove the moisture content in the humid air in the refrigerating chamber simultaneously, when freezer temperature reaches design temperature, the work of master board control conversion equipment realizes the conversion of evaporator fin and refrigerating evaporator.
The utility model compared with prior art has following advantage:
(1) the utility model cooling rate is fast, and refrigeration and fresh keeping property are good;
(2) defrost of the utility model refrigeration system is fast, effectively removes the moisture in the humid air in the refrigerating chamber, and frosting is few, and the heat exchange efficiency height is easy to energy-conservation;
(3) noise is little in the utility model refrigeration system running, reaches quiet effect;
(4) the utility model can be according to user's specific requirement, and refrigerating chamber, refrigerating chamber all can be closed separately, and energy-saving effect is better.
Description of drawings
Fig. 1 is the work schematic diagram of the direct-cooled refrigeration system of prior art refrigerator;
Fig. 2 is the work schematic diagram of prior art refrigerator air cooling refrigeration system;
Fig. 3 is a kind of frost-free refrigerator refrigeration system of the utility model work schematic diagram.
The specific embodiment
Fig. 1 is the work schematic diagram of the direct-cooled refrigeration system of prior art refrigerator, and refrigeration evaporator, refrigerating evaporator, compressor, condenser are connected in series and form the refrigerating circuit of direct-cooled system.
Fig. 2 is the work schematic diagram of prior art refrigerator air cooling refrigeration system, and evaporator fin and compressor, condenser are serially connected in the refrigerating circuit of air cooling system.
As shown in Figure 3, a kind of refrigeration system of frost-free refrigerator, comprise refrigeration system and the refrigerating system that comprises refrigeration evaporator by evaporator fin and refrigerating evaporator parallel connection, refrigeration system and refrigerating system are connected in parallel then and compressor, condenser is connected to form closed refrigerating circuit, this refrigeration system also comprises the realization refrigerating chamber, the magnetic valve that evaporator fin is changed mutually in refrigerating chamber switching and the refrigeration system, and the master board of control magnetic valve, master board through feedback signal and programmed values relatively after conversion by the control magnetic valve realize refrigerating chamber, evaporator fin and refrigerating evaporator conversion in refrigerating chamber switching and the refrigeration system, wherein the signal of master board source has three kinds, i.e. the temperature signal of refrigerating chamber temperature-sensitive head feedback, the temperature signal of the enabling signal of door switch place feedback and refrigerating chamber temperature-sensitive head feedback.
The running of above-mentioned refrigeration system is: the beginning of household refrigerator-freezer energising refrigeration, control the evaporator fin work that allows earlier by master control borad, realize the refrigerating chamber fast cooling, remove the moisture content in the humid air in the refrigerating chamber simultaneously, when freezer temperature reaches design temperature (for example-5 ℃), the temperature signal control magnetic valve conversion of refrigerating chamber temperature-sensitive head feedback is received in master board, realizes the conversion of evaporator fin and refrigerating evaporator.
Because this intrasystem refrigeration system is in parallel with refrigerating system, thereby refrigerating chamber and refrigerating chamber all can be realized independent switching, the operation of refrigerating chamber is not influenced by freezing system works, move voluntarily according to the temperature conditions in the refrigerating chamber fully. as a same reason, refrigerating chamber is not influenced by temperature of refrigerating chamber yet, moves voluntarily according to temperature conditions in the refrigerating chamber.This refrigeration system combines the advantage of two kinds of systems, is easy on refrigerator product, realize, and the operational efficiency height, energy consumption is little, simultaneously food refrigerated and good refreshing effect.
