Abstract
The utility model discloses a refrigerating system for a refrigeration house; the refrigerating system can be used for separate defrosting for single evaporators, the refrigeration house does not need to be cleared, the defrosting process control is flexible, and the usage of the whole refrigeration house is not affected. The refrigerating system disclosed by the utility model comprises a compressor, evaporators, a throttle valve, a condenser and a gas-liquid separator which are connected sequentially by virtue of a refrigerant pipeline; the refrigerant pipeline is finally connected to the compressor for forming a loop; each evaporator is provided with a defrosting heater; the defrosting heater is provided with a defrosting fan; the refrigerant pipeline is provided with a branch pipeline which can be used for controlling the refrigerant in the refrigerant pipeline for passing through the evaporators or not passing through the evaporators; the branch pipeline is provided with an electromagnetic valve. Further, the refrigerant pipeline is provided with at least two evaporators in parallel.
Description
Technical field
The utility model relates to art of refrigeration units, is specifically applied to the refrigeration of freezer.
Background technology
For the refrigeration plant of freezer, its evaporimeter tends in freezer, arrange many groups, due to long refrigeration, can coagulate frost or freeze on evaporimeter, affects the refrigeration of evaporimeter; Therefore freezer can regularly clear out goods, and conversion refrigeration system, is converted to condenser by evaporimeter and heats to defrost; Whole defrost process high cost, not only will clear up freezer, has also wasted the time, and whole refrigeration system of while is relative complex also.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, a kind of freezer refrigeration system is provided, and this refrigeration system can defrost separately for single evaporimeter, does not need to clear up freezer, defrost process is controlled flexibly, does not affect the use of whole freezer.
The utility model solves the technical scheme that its technical problem adopts: a kind of freezer refrigeration system, comprise the compressor connecting successively by refrigerant tubing, evaporimeter, choke valve, condenser, gas-liquid separator, refrigerant tubing is finally connected to compressor and forms loop, on described evaporimeter, Defrost heater is installed, defrosting blower fan is installed on Defrost heater, on described refrigerant tubing, be provided with the cold-producing medium controlled in refrigerant tubing through or without the shunt conduit of evaporimeter, magnetic valve is installed in shunt conduit.
Further, on above-mentioned refrigerant tubing, at least two evaporimeters have been installed in parallel.
The utility model compared with prior art has the following advantages:
A kind of freezer refrigeration system of the utility model, heats blowing hot-air to evaporimeter and defrosts rapidly by heater is set near each evaporimeter; In the process of defrosting, by shunt conduit, make cold-producing medium without evaporimeter, further accelerated defrosting speed; Single evaporimeter defrosts separately, and other evaporimeters are unaffected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-condenser, 2-gas-liquid separator, 3-compressor, 4-Defrost heater, 5-magnetic valve, 6-evaporimeter, 7-magnetic valve, the 8-blower fan that defrosts, 9-choke valve, 10-refrigerant tubing, 11-cooling fan.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model specific embodiment is described:
Fig. 1 shows a kind of concrete structure of the related cotton-wadded quilt body of the utility model, as shown in the figure, a kind of freezer refrigeration system, comprise the compressor 3 connecting successively by refrigerant tubing 10, evaporimeter 6, choke valve 9, condenser 1, gas-liquid separator 2, refrigerant tubing is finally connected to compressor 3 and forms loop, on described evaporimeter 6, Defrost heater 4 is installed, defrosting blower fan 8 is installed on Defrost heater 4, on described refrigerant tubing 10, be provided with the cold-producing medium controlled in refrigerant tubing through or without the shunt conduit 7 of evaporimeter 6, magnetic valve 5 is installed in shunt conduit 7.
Further, on above-mentioned refrigerant tubing 10, at least two evaporimeters 6 have been installed in parallel.
By reference to the accompanying drawings the utility model preferred embodiment is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
Do not depart from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
