Abstract

The utility model relates to a refrigerating circuit, in particular to a refrigerating circuit of a mechanical refrigerator, which effectively utilizes refrigerant discharged from a compressor, increases temperature of a refrigerating chamber, prolongs start time of the compressor and increases freezing capacity. The refrigerating circuit comprises the compressor, a three-way pipe A, a three-way pipe B, a condenser, a drying filter, a capillary pipe, a freezing evaporator, a refrigerating evaporator and a return pipe, wherein the compressor, the three-way pipe A, the three-way pipe B, the condenser, the drying filter, the capillary pipe, the freezing evaporator, the refrigerating evaporator and the return pipe are sequentially connected to form the refrigerating circuit, and a refrigerating branch passing through the refrigerating evaporator is arranged between the three-way pipe A and the return pipe. During a freezing process of the refrigerator, the refrigerating circuit utilizes the high-temperature refrigerant discharged from the compressor, increases the temperature of the refrigerating chamber, prolongs the star time of the compressor, and keeps the temperature of a freezingchamber depressed continuously, thereby increasing freezing capacity and resolving the problem that the mechanical refrigerator is weak in freezing capacity generally.

Description

The refrigerating circuit of mechanical refrigerator
Technical field
The utility model relates to a kind of refrigerating circuit, specifically, relates 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 purpose of this utility model is to overcome above defective, and a kind of cold-producing medium that compressor is discharged that effectively utilized is provided, and improves the temperature of refrigerating chamber, prolongs the available machine time of compressor, the refrigerating circuit that improves the mechanical refrigerator of refrigerating capacity.
The technical scheme of the refrigerating circuit of mechanical refrigerator of the present utility model is such: it comprises compressor, three-way pipe A, condenser, device for drying and filtering, capillary, refrigerating evaporator, refrigeration evaporator, muffler, they are connected to form refrigerating circuit in turn, and the refrigeration branch road through refrigeration evaporator is set between three-way pipe A and muffler.
The refrigeration branch road comprises magnetic valve, three-way pipe B, and magnetic valve and three-way pipe B are arranged between muffler and the three-way pipe A.
The refrigeration branch road through the pipeline of refrigeration evaporator be wrapped in refrigeration evaporator around.
The refrigerating circuit of mechanical refrigerator of the present utility model, 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, the temperature of refrigerating chamber can be lowered the temperature always, thereby reach the effect that improves refrigerating capacity.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 utility model.
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 utility model, they are connected to form refrigerating circuit in turn, and the refrigeration branch road through refrigeration evaporator is set between three-way pipe A and muffler.The refrigeration branch road comprises magnetic valve, three-way pipe B, and magnetic valve and three-way pipe B are arranged between muffler and the three-way pipe A.The refrigeration branch road through the pipeline of refrigeration evaporator 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, and another road then is a high temperature refrigeration branch road: after cold-producing medium is discharged by compressor, through magnetic valve, pipeline converges by a three-way pipe and normal refrigeration system loop through refrigeration evaporator, by muffler, get back to compressor again.The pipeline of high temperature refrigeration 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.
