Abstract
The utility model relates to a multi-cycle refrigeration system of a refrigerator, which adopts a main structure that a compressor, an evaporation mechanism and a liquid storage cylinder are connected in series and in sequence to form a closed cycle system. A condenser is connected in series between the compressor and the evaporation mechanism; and the evaporation mechanism is formed in the way that a refrigerating chamber branch circuit, a freezing chamber branch circuit and a first alternating temperature chamber branch circuit are connected in parallel. The utility model has the advantages of remarkable reduction of cool leakage at the door seal part, simple structure, convenient installation and use, and lower energy consumption. Therefore, under the premise of meeting the cooling requirement, loss caused since refrigerant must flow throughout the entire condensing tube whether needed or not, great flowing loss caused when the refrigerant passes through the frost prevention tube and the loss of the cold of the refrigerating chamber are all avoided.
Description
Technical field
The utility model relates to a kind of refrigerator, ice chest refrigeration system, the many cycle refrigeration systems of particularly a kind of refrigerator-freezer.
Background technology
The compression-type refrigerating system of present existing refrigerator, refrigerator-freezer is by compressor, condenser, and filter, capillary, evaporimeter, liquid storage cylinder, what return duct was formed closes and the loop.Wherein evaporimeter is according to freezing, and the quantity of stored under refrigeration chamber is divided into corresponding section each chamber that in series is placed in (refrigerating chamber, refrigerating chamber and temperature-changing chamber), and whole system is that a single cycle falls after rise.In order to solve existing each apotheca of this single cycle circuit system temperature control separately, and the higher defective of energy consumption, many closed circuits system that each chamber evaporimeter is in parallel has appearred.The temperature of each chamber can more independently be controlled under such system, and makes the corresponding reduction of energy consumption.Yet in this system, though evaporimeter is connected in parallel on and can forms each apotheca between condenser and the liquid storage cylinder and independently move branch road, condenser is still shared, and the chamber that refrigerator, refrigerator-freezer divided is many more, and condenser pipe is long more.Long condenser pipe.With regard to energy consumption, along with the also constantly increase of increase energy consumption of condensation section length.In addition, there is one section in the condenser as refrigerating chamber frost prevention pipe, under the situation of common condenser, the operation of the branch road of whichever chamber, the frost prevention pipe all will produce high temperature and make the refrigerating chamber loss of refrigeration capacity.Thereby still there is the unnecessary energy consumption problem of refrigerator in present this many cycle refrigeration systems.
The utility model content
Technical problem to be solved in the utility model is that the structure of the refrigeration system of present employed refrigerator, refrigerator-freezer exists the high shortcoming of energy consumption to design a kind of energy-conservation, general many cycle refrigeration systems.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Technical disadvantages at existing refrigerator, ice chest refrigeration system exist designs the many cycle refrigeration systems of a kind of refrigerator-freezer, and its primary structure is a closed circulation system that is concatenated into successively by compressor, evaporation mechanism, liquid storage cylinder.Between above-mentioned compressor and evaporation mechanism, be in series with a condenser.Described evaporation mechanism is formed in parallel by refrigerating chamber branch road, refrigerating chamber branch road and the first temperature-changing chamber branch road three parts.
Described refrigerating chamber branch road is to be in series successively by a magnetic valve, a frost prevention pipe, a condenser, a filter, a capillary and a freezing chamber evaporator coil pipe.
The described refrigerating chamber branch road and the first temperature-changing chamber branch road are connected on the filter, the shared filter of the refrigerating chamber branch road and the first temperature-changing chamber branch road.
Described refrigerating chamber branch road is to be in series successively by a magnetic valve, a capillary and a refrigerating chamber evaporation coil.
The described first temperature-changing chamber branch road is to be in series successively by a magnetic valve, a capillary and one first temperature-changing chamber evaporation coil.
The thermic load size that the utility model is freezing according to refrigerator, the quantity of refrigerating chamber is different with each chamber is divided into several parts that length and evaporimeter thermic load are complementary with condenser.The utility model when work can according to refrigerating chamber, refrigerating chamber and temperature-changing chamber whether the demand of needs cooling open magnetic valve on refrigerating chamber branch road, refrigerating chamber branch road and the first temperature-changing chamber branch road, allow the cold-producing medium that flows out from compressor flow through this part body, can significantly reduce the length of cold-producing medium, effectively reduce the energy consumption of product through capillary and evaporimeter.Simultaneously the frost prevention pipe independently is arranged on the road of refrigerating chamber, when not needing refrigerating chamber freezed, cold-producing medium does not just need to flow through the frost prevention pipe.
Between condenser that is connected with compressor and evaporation mechanism, be in series with a magnetic valve and a condenser successively.According to the needs of design, when product needed increases a temperature-changing chamber more, evaporation mechanism with the evaporation mechanism condenser that links to each other on be parallel with the second temperature-changing chamber branch road.The second temperature-changing chamber branch road is to be in series successively by a magnetic valve, a filter, a capillary, second a temperature-changing chamber evaporation coil.
Behind such scheme reasonable distribution condenser, the cold-producing medium in the apotheca branch road that is just moving flows through needed condensation section length, and needn't flow through the whole condenser pipe of refrigerator, and certainly branch road that also needn't each operation all will pass through the frost prevention pipe.Therefore, under the prerequisite that satisfies the cooling requirement, the condenser pipe and the process caused big flow losses of frost prevention pipe and the loss of refrigerating chamber cold that whether need cold-producing medium all must cover whole length have been avoided.The energy consumption of many cycle refrigeration systems described in the utility model is lower.
