Embodiment Construction

[0024] Such as figure 1 , Figure 5 As shown, two parallel-connected evaporators (5, 7) are installed in the refrigeration cycle system of the present invention, and the two sides of the parallel-connected evaporators (5, 7) are connected with refrigerant compression capacity variable compressors (1) and condenser (3). A valve (9) for controlling the refrigerant pipeline is also connected to one side of the discharge port of the evaporator (5, 7). In addition to the above devices, the refrigeration cycle system is also equipped with compressed air cylinders, dryers, detection valves, etc. Although not shown in the figure, in fact, the above two evaporators (5, 7) are respectively installed in mutually isolated spaces. Therefore, the operation of sending the refrigerant to the two evaporators (5, 7) is based on the temperature monitored by the temperature sensors (100, 110) installed in the respective spaces described later.

[0025] In addition, the refrigerator adopting t...

Abstract

In the refrigerating circulation system with compressor of variable refrigerant compressing volume and several parallel evaporators, several evaporators are installed separately in isolated spaces, and the compressor of variable refrigerant compressing volume has its piston stroke controlled based on the number of operating evaporators. The present invention has reduced power consumption via controlling the compressor piston stroke.

Description

technical field [0001] The invention relates to a refrigerating cycle system using a compressor with variable refrigerant compression capacity. Background technique [0002] In products such as refrigerators and air conditioners used for refrigeration, freezing, or for generating cold air and warm air, the cold air or warm air required inside the product is generally generated through a heat exchange process. The above heat exchange process is realized in the refrigeration cycle system, the structure of this refrigeration cycle system is: compressor → condenser → evaporator, and then reconnected to the compressor. The compressor can compress the refrigerant in the low-temperature and low-pressure state into a high-temperature and high-pressure state and then discharge it. The refrigerant compressed into a high-temperature and high-pressure state by the above-mentioned compressor can realize the first heat exchange process when flowing through the condenser, and then can rea...
