Description

A kind of freezer refrigeration system

Technical field

The utility model relates to refrigeration technology field, specially a kind of freezer refrigeration system.

Background technique

Currently, the most of freezers in China are all made of single refrigeration machine cooling, refrigeration machine cooling, which is used for a long time, can be consumed greatly The electric power resource of amount, while use cost is also increased, it is lower in northern especially the Northeast's winter outdoor temp, and this is practical It is novel to propose a kind of freezer using this lower feature of north of china in winter outdoor temperature and solved among the above with refrigeration system Problem.

Utility model content

It is mentioned above in the background art to solve that the purpose of this utility model is to provide a kind of freezer refrigeration systems Problem.

To achieve the above object, the utility model provides the following technical solutions: a kind of freezer refrigeration system, includes refrigeration Unit one, refrigeration unit two and heat exchange refrigeration cycle unit, the refrigeration unit one include evaporator and heat exchange refrigeration cycle machine Group, and the refrigeration cycle unit that exchanges heat includes blower and circulating pump, the refrigeration unit two includes refrigeration machine and heat exchange refrigeration unit, And state refrigeration unit two and cold group one processed and work independently, the both ends of the evaporator and refrigeration machine are connected with by pipeline respectively Blower and circulating pump.

Preferably, the evaporator is that evaporation is cold.

Preferably, the refrigeration unit one and refrigeration unit two form an enclosed with heat exchange refrigeration cycle unit respectively and follow Loop system.

Preferably, medium valve one is provided on the pipeline between the evaporator and circulating pump.

Preferably, medium valve two is provided on the pipeline between the refrigeration machine and blower.

Compared with prior art, the utility model has the beneficial effects that the utility model, which uses, is set side by side with refrigeration machine Group one, two two lines road of refrigeration unit, can be selected by switchable dielectric valve one and medium valve two be applicable in refrigeration machine or Person's evaporator carrys out cooling medium, and the utility model makes full use of the north, particularly the Northeast, the low spy of winter outdoor temperature Point, it is alternative in winter to close refrigeration machine, using evaporator to achieve the purpose that radiate using outdoor cold wind, realize freezer system It is cold, reduce the consumption of electric power compared with refrigeration machine cooling is used for a long time in freezer in the prior art, to also reduce refrigeration system The use cost of system.

Detailed description of the invention

Fig. 1 is the working principle diagram of the utility model.

In figure: 1, evaporator；2, blower；3, circulating pump；4, refrigeration machine；5, medium valve one；6, medium valve two.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Fig. 1, a kind of embodiment provided by the utility model: a kind of freezer refrigeration system includes refrigeration unit One, refrigeration unit two and heat exchange refrigeration cycle unit, the refrigeration unit one include evaporator 1 and heat exchange refrigeration cycle unit, The evaporator 1 is that evaporation is cold, and power consumption is few, operating cost is low, and heat exchange efficiency is high, and the refrigeration cycle unit that exchanges heat includes blower 2 and circulating pump 3, the refrigeration unit two includes refrigeration machine 4 and heat exchange refrigeration unit, and states refrigeration unit two and cold group one processed It works independently, the refrigeration unit one and refrigeration unit two form a closed cycle system with heat exchange refrigeration cycle unit respectively System can be such that refrigeration unit one or two freezer of refrigeration unit recycles and freeze incessantly, safe and reliable to operation, the equipment longevity Life length, makes refrigeration unit one and refrigeration unit two, and the both ends of the evaporator 1 and refrigeration machine 4 pass through pipeline respectively and are connected with wind Machine 2 and circulating pump 3 are provided with medium valve 1 on the pipeline between the evaporator 1 and circulating pump, pass through control dielectric valve Door 1 controls the working condition of refrigeration unit one, is provided with medium valve on the pipeline between the refrigeration machine 4 and blower 2 26, the working condition of refrigeration unit two is controlled by control medium valve 26, can control medium according to seasonal variations Valve 1 and medium valve 26, so as to select to carry out cooling medium suitable for refrigeration machine 4 or evaporator 1.

Working principle: medium valve 1 can be opened when in winter and starts the work of refrigeration unit one, the refrigeration unit one Using the cold cold air by the external world of evaporation come to medium cooling, cryogenic media enters the fan coil in freezer, by blower 2 One blows, and medium temperature has raising, is then flowed through by circulating pump 3 and evaporates cold and cooled down by cool ambient air, to form one A closed circulation system can constantly freeze to freezer, and refrigeration unit one can carry out suitably according to outdoor temperature Cooling can close medium valve 1 after winter and open simultaneously medium valve 26, start two work of refrigeration unit Make, refrigeration machine 4 freezes to freezer at this time, since refrigeration unit one and refrigeration unit two can be cut at any time according to season Change jobs state, selects to be applicable in refrigeration machine or evaporator carrys out cooling medium, to achieve the effect that refrigeration.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
