Background technology
Refrigeration plant is in running; The inner impurity of refrigeration system also can be along with cold-producing medium circulates together; For preventing that impurity from stopping up capillary; Refrigeration plant is provided with the device for drying and filtering of impurity screening before capillary, but some tiny impurity and greasy dirt still can flow to capillary through device for drying and filtering.Impurity in the refrigerating device refrigeration system is generally the binding of greasy dirt and metal fillings, molding sand etc., is easy in the capillary front end, assemble and stop up.Handling the common method of stopping up now is: knock capillary gently earlier, take a chance, look at that can the impurity that stop up through obstruction place in vibration; Just refrigeration system is opened, replacing filter dirty, this way with the elevated pressure nitrogen air-blowing as not all right; Need bleed off and change cold-producing medium, refrigeration oil, change filter, complicated operation; Time-consuming, and waste material.
Summary of the invention
The objective of the invention is to overcome defective of the prior art, adopt a kind of cycle of higher pressure anti-clogging refrigeration plant, when capillary stops up; Utilize the cold-producing medium of HTHP to circulate and blow out impurity; Avoid stopping up, control, making and installation are simple, easy operating.
For realizing above-mentioned purpose; Technical scheme of the present invention is to adopt a kind of cycle of higher pressure anti-clogging refrigeration plant; Comprise evaporimeter, capillary b end, four-way change-over valve right-hand member pipe, four-way change-over valve low-voltage tube, four-way change-over valve left end pipe, four-way change-over valve coil, spool, compressor, four-way change-over valve high-voltage tube, capillary a end, condenser, device for drying and filtering, magnetic valve; Described compressor, condenser, device for drying and filtering, four-way change-over valve high-voltage tube, four-way change-over valve low-voltage tube, evaporimeter closed loop successively connect; Described capillary a end is connected with four-way change-over valve left end pipe, and described capillary b end is connected with four-way change-over valve right-hand member pipe.
Described compressor exhaust pipe is connected with the four-way change-over valve high-voltage tube through magnetic valve.
The coil of described four-way change-over valve coil and magnetic valve is connected with the control circuit of refrigeration plant through control line respectively.
Basic principle of the present invention: after using the present invention, the refrigeration system fine impurities can see through device for drying and filtering, is flowing to front end capillaceous and is stopping up; Open magnetic valve this moment; The HTHP exhaust of bypass compressor through the flow direction of four-way change-over valve switching cold-producing medium, makes cold-producing medium flow from opposite direction capillaceous; Impurity is blown out from capillary, prevent to stop up.
Beneficial effect of the present invention is:
(1) utilizes the compressor air-discharging of HTHP that impurity is blown out, avoid stopping up.
(2) need not open refrigeration system, just can get rid of obstruction, practice thrift maintenance time and material.
(3) control, making and installation are simple, are easy to production operation.
