Fig. 2 is an apartment-type refrigeration system of refrigerator schematic diagram of the present utility model;
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, apartment-type refrigerator of the present utility model, arrange label from top to bottom and be four refrigerator chambers of 1～4, the bottom is a freezing compartment 5, the refrigerating chamber 5 of bottom is public, independently door is all established in each refrigerator chamber on refrigerating chamber 5 tops, and is provided with the door lock that can independently control on every fan refrigerating-chamber door, makes the user of refrigerator chamber can use this chamber separately and can not arbitrarily open other chamber.The design temperature of four refrigerator chambers is between 4-7 ℃, and freezing compartment's temperature of bottom is arranged between-20～-15 ℃.
Fig. 2 illustrates apartment-type refrigeration system of refrigerator of the present utility model topology layout.At present, the refrigeration modes of refrigerator mainly contains air-cooled and direct-cooled two kinds.Under equal conditions, direct-cooled mode is simpler than air cooling way, and noise is low and power consumption is low.General refrigerator generally has only a refrigerator chamber and a freezing compartment, apartment-type refrigerator of the present utility model then is provided with a plurality of refrigerators chamber and single freezing compartment, key is: the on the one hand temperature of each chamber requirement that will be up to state standards, the temperature of each refrigerator chamber keeps consistency again on the other hand.Though adopt air channel structure to send the air-cooled refrigeration modes of cold wind also can reach temperature controlled requirement to each chamber, but consider from the aspect of system architecture simplification, cost savings and low energy consumption, the refrigerant system design of present embodiment refrigerator adopts direct-cooled refrigeration modes and single-point temperature control system, makes overall cost reduction, the temperature control of refrigerator simple when satisfying the requirement of refrigerator storage temperature.Refrigerator controller is arranged on refrigerator top cover or the door body, can regulate each room temperature degree for each user.The temperature control of controller is divided into seven grades; the temperature control point is located in the refrigerator chamber 1 at top; specifically be at locational certain point of an indoor chamber evaporimeter, utilize a temperature sensor senses startup-shutdown temperature, control the operation of freezer compressor by the temperature regime that detects this point.As shown in Figure 2, temperature-sensitive conduit 6 is arranged between the first row's U-shaped pipe and second row's U-shaped pipe of this chamber R evaporimeter, and temperature sensor (also being temperature-sensitive head) is inserted in the temperature-sensitive conduit 6.The temperature of indoor induction inner air between the modes of emplacement of above-mentioned temperature-sensitive head can also be arranged on.It is indoor that above-mentioned temperature sensor (temperature-sensitive head) also can be located at other refrigerator.The evaporimeter of refrigerator chamber is the R evaporimeter 7 of band-tube type, sticks on the inner chamber back wall of each refrigerator chamber dress fiber tube evaporimeter 16 in the freezing compartment.After compressor 14 starts, cold-producing medium enters condenser 18 through escape pipe 15, by device for drying and filtering 11 small amount of moisture in the cold-producing medium is filtered after the condensation, be introduced into the F evaporimeter 16 interior evaporations of refrigerating chamber through capillary 9, reduce the temperature of freezing compartment 5, the mixed working fluid of part evaporation enters in the R evaporimeter 7 of refrigerator chamber 1～4 from F evaporimeter 16, the cold-producing medium trend of R evaporimeter 7 is the refrigerator chambers 1 that are introduced into the refrigerator top, and it is indoor to enter each refrigerator successively by refrigerator chamber 2, refrigerator chamber 3 and refrigerator chamber 4 orders again.Get back in the compressor 14 through after reservoir 8, muffler 10 and the air inlet pipe 13 from the cold-producing medium that evaporimeter comes out, so far finished a kind of refrigeration cycle.The electrical box of label 12 expression compressors.
For the temperature that makes each refrigerator chamber of refrigerator, freezing compartment should reach the refrigerator request of national standard, the temperature of each refrigerator chamber is consistent as far as possible again, on calculation of Heat Load basis to each chamber of refrigerator, determine the size of the disengagement area of each chamber, by the optimal design of refrigerator chamber R evaporimeter 7, realize the uniformity of each refrigerator room temperature.Referring to Fig. 1, five faces of refrigerator chamber 1 are subjected to directly influencing of ambient temperature, its heat load maximum, and refrigerator chamber 4 contiguous freezing compartment 5, its heat load minimum, and the heat load of chamber is placed in the middle between No. 2, No. 3.Therefore, the evaporation tube total surface area of chamber design maximum and evaporation tube spacing are corresponding less than normal guaranteeing the temperature inside the box between No. 1, and the evaporation tube total surface area of chamber equates and less than the evaporation tube gross area of chamber between No. 1, chamber evaporation tube spacing maximum between No. 4 between 2,3, No. 4.With the about 200L of internal volume, each chamber essentially identical apartment-type refrigerator of size is example, adopt the mode of a plurality of evaporator series, science to major parameters such as disengagement area, evaporation tube tube pitch, working medium charging amounts is calculated, produce the suitable apartment-type refrigerator of a function admirable, low energy consumption and compressor operating coefficient, this refrigerator adopts the mode of single temperature controller, a plurality of evaporator series, concrete parameter and performance data see the following form, table 1 is that related parameter and power consumption are arranged, and table 2 is temperature datas of each chamber of refrigerator:
