Abstract
The utility model discloses an energy-saving starter for refrigeration compressor of a refrigerator or a freezer, comprising a shell, and a starting circuit installed in the shell; the starting circuit comprises an overcurrent relay RJ, a positive temperature coefficient thermistor R, and a capacitor C; one end of the overcurrent relay RJ is electrically connected with an electrode of the alternating current power supply, and the other end is electrically connected with the joint of the starting coil and the working coil of the refrigeration compressor D; after the thermistor R and the capacitor C are connected in parallel, one end is electrically connected with the working coil output end of the refrigeration compressor D, and the other electrode of the alternating current power supply, and the other end is electrically connected with the starting coil output terminal of the refrigeration compressor D. The utility model has the advantages that in the condition of the refrigeration compressor D with same rated power works, not only the starting torque is enlarged, but also the working current of the refrigeration compressor D is reduced by 25-30%, so the utility model saves electric energy as well as decreases running cost of the refrigerator and the freezer.
Description
Technical field
The utility model relates to a kind of refrigeration compressor starter, especially relates to a kind of energy-saving starter that is used for refrigerator, refrigerator-freezer refrigeration compressor.
Background technology
The starter that is used for refrigerator, refrigerator-freezer refrigeration compressor at present, its function singleness, main effect is the rotating torque when improving the refrigeration compressor starting.And when the refrigeration compressor starting was afterwards in running order, starter promptly quit work.How to utilize starter to make it when refrigeration compressor is worked, can play energy-saving and cost-reducing effect, up to the present yet there are no the report of relevant this respect.
Summary of the invention
The purpose of this utility model is to provide a kind of energy-saving starter that is used for refrigerator, refrigerator-freezer refrigeration compressor at above-mentioned existing in prior technology deficiency.
For achieving the above object, the utility model can be taked following technical proposals:
The energy-saving starter that is used for refrigerator, refrigerator-freezer refrigeration compressor described in the utility model, it comprises housing, is arranged on the starting circuit in the described housing, described starting circuit is made of overcurrent relay RJ, semistor R, capacitor C; The end of described overcurrent relay RJ is electrically connected with an electrode of AC power, and its other end is electrically connected with the starting winding of refrigeration compressor D and the contact of work winding; After described thermistor R, capacitor C were parallel with one another, the one end was electrically connected with the output of refrigeration compressor D work winding, another electrode of AC power, and its other end starts the winding output with refrigeration compressor D and is electrically connected.
Described semistor R is the PTC thermistor.
Advantage of the present utility model is to have adopted the parallel circuit that is made of semistor R, capacitor C, and an end of this parallel circuit is electrically connected with the output of refrigeration compressor D work winding, an electrode of AC power, the other end is electrically connected with the output of refrigeration compressor D starting winding, thereby be implemented under the same nominal power refrigeration compressor D condition of work, not only starting torque is amid a sharp increase, operating current during refrigeration compressor D work simultaneously reduces 25-30%, save electric energy greatly, reduced the operating cost of refrigerator, refrigerator-freezer.
