Description
Technical field
This utility model is related to art of refrigeration units, especially a kind of R290 cold-producing mediums refrigerator.
Background technology
Refrigerator is to maintain a kind of refrigeration plant of constant low temperature, and one kind makes food or other articles keep constant low temperature
The product for civilian use of cold conditions.There are compressor, ice machine in casing to the cabinet that freezes or case, the hutch with refrigerating plant.It is super
Cryogenic refrigerator is also known as ultralow temperature refrigerator-freezer, ultra-low temp.By being broadly divided into：The preservation of applicable tuna, electronic device,
The low-temperature test and preservation blood plasma of special material, biomaterial, vaccine, reagent, biological product, chemical reagent, strain, biological sample
This grade cryopreservation.
The refrigerator of existing more than 260W refrigerating capacitys its adopt R134a for cold-producing medium.Although R134a cold-producing mediums do not destroy air
Ozone layer in layer, but its greenhouse gases effect for producing is very big, and the requirement of the impurity content of requirement and system to material is all
It is very high, and the high energy consumption of product, R134a cold-producing mediums are not suitable for using in extremely hot or torrid areas, due to enervated characteristic
Higher energy consumption, refrigerating capacity are less than the refrigerator of 260W, electric refrigerator and all adopt R600a cold-producing mediums.In more than 260W refrigerating capacitys
Refrigerator is using the good selection that R290 cold-producing mediums are the defects that solution R134a makees cold-producing medium.
Utility model content
This utility model aims to provide a kind of R290 cold-producing medium refrigerators of employing R290 cold-producing mediums.
For achieving the above object, this utility model provides following technical scheme：R290 cold-producing medium refrigerators, including cabinet, institute
The bottom side for stating cabinet is provided with units' installation room, and cryogenic compressor, intercooler, high temperature compressed is provided with units' installation room
Machine, condenser and blower fan, the freezing interior of cabinet are provided with vaporizer, cryogenic compressor, intercooler, high temperature compressor, cold
Condenser, blower fan and vaporizer composition double-stage compressive refrigerating system, filling R290 cold-producing mediums, institute in the double-stage compressive refrigerating system
The outlet connection cryogenic compressor of vaporizer is stated, the import connection intercooler of vaporizer, described blower fan are located at condenser
Side, the cryogenic compressor and high temperature compressor connection circuit board, circuit board connect plug by wire.
As further scheme of the present utility model：The bottom of the cabinet is installed by universal caster wheel.
Compared with prior art, the beneficial effects of the utility model are：R290 cold-producing mediums are replaced by the R290 cold-producing mediums refrigerator
Change R134a cold-producing mediums for more than 260W refrigerating capacitys refrigerator, using ripe R600a refrigerant products production technology and
Technology, by the refrigeration system for matching refrigerator, can improve the quality of product, reduce the manufacturing cost of product, reduce product
Energy consumption, improves the refrigerating capacity of product, extends the service life of product, is worth promoting.

Fig. 1-2 is referred to, in this utility model embodiment, R290 cold-producing medium refrigerators, including cabinet 21, the cabinet 21
Bottom side is provided with units' installation room 22, is provided with cryogenic compressor 1, intercooler 2, high temperature compressor in units' installation room 22
3rd, condenser 4 and blower fan 5, the freezing interior of cabinet 21 are provided with vaporizer, cryogenic compressor 1, intercooler 2, high temperature compressed
Machine 3, condenser 4, blower fan 5 and vaporizer composition double-stage compressive refrigerating system；Filling R290 refrigeration in double-stage compressive refrigerating system
Agent, as coolant.
It is above-mentioned, the outlet connection cryogenic compressor 1 of vaporizer, the import connection intercooler 2 of vaporizer.
Above-mentioned, universal caster wheel is installed in the bottom of cabinet 21.
It is above-mentioned, cryogenic compressor 1 and the connection circuit board of high temperature compressor 3, circuit board connects plug by wire.
Above-mentioned, blower fan is located at condenser side.
R290 cold-producing mediums are replaced R134a cold-producing mediums by this utility model is used for the refrigerator of more than 260W refrigerating capacitys.Utilize
The production technology and technology of ripe R600a refrigerant products, by the refrigeration system for matching refrigerator, can improve the matter of product
Amount, reduces the manufacturing cost of product, reduces the energy consumption of product, improves the refrigerating capacity of product, extends the service life of product.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
