Description
Technical field
It the utility model is related to a kind of refrigeration plant, and in particular to a kind of outer liquid-spraying type condensation unit.
Background technology
With the continuous popularization of the service locations such as market and supermarket, business is super, and refrigerator market capacity is constantly lifted, and is condensed
Core component of the unit as the super refrigeration system of refrigerator of business, its usage amount are also soaring year by year.In freezing and refrigeration field, refrigeration
System has special requirement to the compressor in condensation unit.Because refrigeration system is in the case where evaporating temperature is relatively low, compression
The compression ratio of machine can increase, and this results in the increase of compressor electric motor caloric value；But because evaporating temperature is low, the system in refrigeration system
Cryogen flow is smaller so that heat caused by compressor can not distribute quickly, so as to cause compressor heat to be protected, or even directly
Connecing causes compressor to burn.
The compressor for being currently used in freezing and refrigeration field is mostly piston compressor, and piston compressor is adaptable
By force, the advantages of simple in construction, it is widely used in Small And Medium Capacity refrigerating field.But the rotating speed of piston compressor and less efficient,
It is difficult to meet the capacity requirement of the super refrigerator of business.The problem of in order to overcome Thermal protection under rotor-type compressor worst cold case, can
Refrigerating field is well adapted to, a kind of hydrojet rotor-type compressor occurs in the market, i.e., inside compressor and shell
Between open a hydrojet passage, the refrigerant liquid of condensator outlet is injected directly into compression after one section of capillary-compensated expands
In the cylinder of machine, it is cooled down.So as to reach and meet -40 DEG C of freezing and refrigeration field refrigeration system evaporating temperature ~ -
10 DEG C, the requirement of 20 DEG C ~ 65 DEG C of condensation temperature.But due to the setting of Liquid injection cooling structure, increase rotor-type compressor
Structural complexity, improve difficulty of processing, improve cost, and available model is few, can not replace conventional piston formula pressure always
Leading position of the contracting machine in freezing and refrigeration field.
Occupy rotor-type compressor maximum occupancy volume on the market is idle call rotor-type compressor, idle call rotator type pressure
Contracting machine technology maturation, has realized industrialized mass production, and cost is cheap, and model is complete.But because structure limits, its use range
It is in -5 DEG C ~ 10 DEG C of evaporating temperature, 20 DEG C ~ 54 DEG C of condensation temperature, freezing and refrigeration field can not be used in.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of outer liquid-spraying type condensation unit, using the hydrojet system of peripheral hardware
System coordinates with rotor-type compressor, has not only given full play to the advantages of rotor-type compressor is simple in construction, cost is low and model is complete,
Also solve the problems, such as Thermal protection under rotor-type compressor worst cold case simultaneously, realize rotor-type compressor and led in freezing and refrigeration
The normal use in domain.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is provided is as follows：A kind of outer liquid-spraying type freezing machine
Group, including compressor, condenser, choke valve and evaporator, described compressor, condenser, choke valve and evaporator pass through pipe
Road joins end to end and forms loop successively, and described compressor is rotor-type compressor；Between described evaporator and compressor
Provided with gas-liquid separator, in addition to hydrojet branch pipe, one end of the hydrojet branch pipe and the entrance of gas-liquid separator connect, the other end
It is connected on the pipeline between evaporator and choke valve.
Preferably, described compressor is idle call rotor-type compressor.
Preferably, it is connected with hydrojet capillary on described hydrojet branch pipe.
Preferably, it is connected with reservoir on pipeline between the condenser and choke valve.
Had the advantages that using above-mentioned technical proposal：
1. the porch connection hydrojet branch pipe of gas-liquid separator, cools down to refrigerant in gas-liquid separator, reduces
The suction temperature of compressor, simultaneously because the refrigerant amount increase of the extra feed flow of hydrojet branch pipe, compressor suction and discharge,
And then effectively raise the internal circulating load of refrigeration system；Meanwhile refrigerant temperature reduces, flow increase is also beneficial to take away more
Heat, be easy to the radiating of compressor moving component and motor, avoid motor and compressor block temperature too high, occur heat protect
Shield.Practice have shown that the technical scheme is compared with convention rotor formula compressor, under comparable operating conditions, housing and motor can be made
Temperature reduces by 30 DEG C or so.After such scheme, idle call rotor-type compressor can directly substitute hydrojet rotator type pressure
Contracting machine is used for freezing and refrigeration field, and because the structure of idle call rotor-type compressor is simple, model is complete, it is cold to greatly reduce freezing
Tibetan field condenses the manufacturing cost of unit, and expands the scope of application of condensation unit.
2. hydrojet branch pipe is connected to gas-liquid separator porch, compared with being connected directly between on compressor housing, cooling
Hydrojet enters back into compressor by gas-liquid separator, effectively avoids compressor and liquid caused by hydraulic compression and hydraulic compression occurs
The problems such as hitting, the risk of the damage of components such as Compressor Air Exhaust Valve Plate, sliding block is reduced, improve the service life of compressor.
3. hydrojet capillary is connected with hydrojet branch pipe described in, hydrojet capillary has certain Flow-rate adjustment effect,
When the pressure differential at hydrojet capillary both ends changes, spouting liquid can also change therewith；In actual use only need to be to hydrojet hair
The working condition of tubule is monitored, it is possible to compressor temperature control within the required range.
4. being connected with reservoir on the pipeline between the condenser and choke valve, reservoir is used to store refrigerant, when
When the open degree of choke valve changes, reservoir can play buffering adjustment effect to the refrigerant flow change in loop.
