The invention relates to a refrigerating circuit, in particular to a refrigerating circuit of a mechanical refrigerator. The refrigerating circuit of the mechanical refrigerator, which is provided by the invention, effectively utilizes the refrigerant discharged by a compressor, increases the temperature of a refrigerating chamber, extends the starting time of a compressor, and improves the freezing capacity. The refrigerating circuit comprises a compressor, a three-way pipe A, a condenser, a dry filter, a capillary pipe, a freezing evaporator, a refrigerating evaporator and an air return pipe which are sequentially connected to form the refrigerating circuit; a refrigerating branch is also arranged in the refrigerating circuit; by taking the three-way pipe A as a starting point, the refrigerating branch is connected to the refrigerating evaporator and then is connected between the condenser and the dry filter; and the refrigerating branch passing through the refrigerating evaporator is a refrigerating heating coil. In the process of improving the freezing capacity of the refrigerator, the refrigerating circuit of the mechanical refrigerator of the invention utilizes the high-temperature refrigerant discharged by the compressor, increases the temperature of the refrigerating chamber and extends the starting time of the compressor, so that the temperature of a freezing chamber can be lowered continuously, thereby achieving the effect on improving the freezing capacity. The invention solves the problem that the freezing capacity of the mechanical refrigerator is generally not great enough.
Description
Technical field
The present invention relates to a kind of refrigerating circuit, specifically, relate to a kind of refrigerating circuit of mechanical refrigerator.
Background technology
The refrigerator of prior art generally all comprises refrigerating chamber, refrigerating chamber, freezing startup is to be carried out by the temperature controller in the refrigerating chamber, as long as the temperature of refrigerating chamber reaches certain scope, temperature controller will start compressor operating, refrigerating chamber and refrigerating chamber freeze simultaneously, when the temperature of refrigerating chamber reaches certain temperature, temperature controller will close compressor, and the high temperature refrigerant that compressor self is discharged is not just well utilized.
Summary of the invention
The objective of the invention is to overcome above defective, a kind of cold-producing medium that compressor is discharged that effectively utilized is provided, improve the temperature of refrigerating chamber, prolong the available machine time of compressor, the refrigerating circuit that improves the mechanical refrigerator of refrigerating capacity.

The refrigerating circuit of mechanical refrigerator of the present invention, in the process of carrying out the refrigerator refrigerating capacity, the high temperature refrigerant that uses compressor to discharge, improve the temperature of refrigerating chamber, prolong the available machine time of compressor, prolong refrigeration, thereby reach the effect that improves refrigerating capacity refrigerating chamber.Solved the general big inadequately problem of this mechanical type refrigerator refrigerating capacity.
Description of drawings
Fig. 1 is the structural representation of the refrigerating circuit of mechanical refrigerator of the present invention.
The specific embodiment
As shown in Figure 1, it comprises compressor, three-way pipe A, condenser, device for drying and filtering, capillary, refrigerating evaporator, refrigeration evaporator, muffler the refrigerating circuit of mechanical refrigerator of the present invention, they are connected to form refrigerating circuit in turn, one tunnel refrigeration branch road also is set in the refrigerating circuit, the refrigeration branch road from three-way pipe A as starting point, be connected to refrigeration evaporator then, be connected then between condenser and the device for drying and filtering, the refrigeration branch road of process refrigeration evaporator is the refrigeration heat(ing) coil.The refrigeration branch road comprises magnetic valve, three-way pipe B, check valve, and magnetic valve is connected between three-way pipe A and the refrigeration evaporator, and three-way pipe B is connected with refrigeration branch road, condenser, capillary, and check valve is arranged between three-way pipe B and the refrigeration evaporator.Refrigeration heat(ing) coil be wrapped in refrigeration evaporator around.
When refrigerator normally used, the effect (closing magnetic valve) by magnetic valve made refrigerator normally move along the loop of compressor-condenser-capillary-evaporimeter-compressor.
When refrigerator began to carry out the experiment of refrigerating capacity, magnetic valve was opened, and two pipeline refrigeration system loops are moved simultaneously.One the tunnel is normal refrigerator refrigeration system loop, another road, then be the branch road of high temperature refrigerant: after cold-producing medium is discharged by compressor, through magnetic valve, pipeline is through refrigeration evaporator, converge by check valve, three-way pipe and normal refrigeration system loop, participate in normal refrigeration by device for drying and filtering, capillary evaporator again, get back to compressor.The refrigeration heat(ing) coil of high temperature refrigerant branch road during through refrigeration evaporator, adopts the refrigeration evaporator mode on every side that is wrapped in, and to improve the temperature of refrigerating chamber, does not also influence the normal refrigeration of refrigeration evaporator simultaneously.
When refrigerator normally used, the refrigeration branch road of increase was isolated fully with normal refrigerating circuit, is to add check valve by magnetic valve.Remove refrigerator and bring into use one of refrigerating capacity (to the quick-frozen of refrigerating chamber) to do the time spent, this magnetic valve of increase be close all the time, obstructed.
