Abstract

The invention discloses a single-capillary electronic control refrigeration system for electronically-controlled refrigerators. The single-capillary electronic control refrigeration system comprises a compressor, a condenser, a filter, the capillary and two or more evaporators in sequential pipe connection, and connection pipes are filled with refrigerant media. The system is characterized by further comprising valves, the two or more evaporators are connected sequentially through pipelines and mounted in independent chambers of the electronically-controlled refrigerator respectively, and each valve is connected between each two evaporators to realize distribution of the refrigerant media in the pipelines to the independent chambers of the electronically-controlled refrigerator. By adoption of the valves with a medium distribution function, refrigerant flow distribution of the control system of the electronically-controlled refrigerator is realized, an independent refrigeration mode of chambers of existing electronically-controlled refrigerators on the market is changed, the refrigeration system with only one capillary for the electronically-controlled refrigerators with double temperature zones or multiple temperature zones is realized, positive effects are achieved, and the refrigeration control system for the electronically-controlled refrigerators is greatly reformed.

Description

technical field

[0001] The invention belongs to the field of control intelligence control, and in particular relates to a single capillary electric control cooling system. Background technique

[0002] Since electronically controlled refrigerators can individually control the temperature of each room, and electronic sensors are used to collect the temperature of each room, so that each room can be precisely controlled, the current market share of electronically controlled refrigerators is getting higher and higher. But at the same time, the refrigeration system adopted by the electronically controlled refrigerator is that each room has a separate capillary tube, that is, the double-door refrigerator adopts a double-capillary system, and the three-door refrigerator adopts a three-capillary structure. This will inevitably lead to an increase in the cost of the refrigerator. In addition, the flow direction of the refrigerant in the electric-controlled refrigerator is from the h...

Embodiment Construction

[0011] A single-capillary electric control refrigeration system for an electric refrigerator, comprising a compressor 1, a condenser 6, a filter 7, a capillary 2 and an evaporator connected by pipelines in sequence, the connecting pipeline is filled with a refrigerant medium flow, and Including valves, the evaporators are two or more evaporators connected by pipelines in turn, installed in each independent room of the electric control refrigerator, the valves are connected between the evaporators to realize the cooling medium in the pipeline in the electric Control the allocation of individual compartments of the refrigerator.

[0012] The valve is a shut-off valve or a two-position three-way valve, similar valves with medium flow distribution function.

[0013] When the control system includes two evaporators, the control system is used for the control of two room electric refrigerators, and the evaporators are freezing evaporators or refrigerating evaporators; when the valve...
