Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the embodiment of the present invention.It should be understood that this
Locate described specific embodiment and be merely to illustrate and explain the present invention embodiment, is not intended to restrict the invention embodiment.
Fig. 1 is the structural schematic diagram for the compressor that one embodiment of the invention provides.As shown in Figure 1, Fig. 1 mentions for the present invention
A kind of movement travel by regulating piston out to realize the capacity for adjusting compressor, and then realizes that adjusting refrigerator is whole
The compressor of mechanism cooling capacity.Normal fixed frequency and frequency-changeable compressor, for compressor in a stroke, piston position is from Fig. 1
In position 1 run to highest distance position Y, between maximum distance Y and cylinder end face reserve certain space be clearance volume, this
The compressor with variable displacement of text invention is that the adjustable realization of stroke is run by piston, and operation stroke can according to manufacturability
It is divided into N kind, each corresponding compressor air-discharging amount is different.Its capacity is divided into following several types:
1, maximum capacity: being that piston is run to farthest in a stroke from position 1 under its maximum capacity state
Position Y (when air-breathing on the contrary, running to position 1 from highest distance position Y), compressor air suction and swept volume are maximum and right at this time
Answer the refrigerant flow in refrigerator refrigeration system big, refrigerating capacity is big, meets the needs of fast-refrigerating；
2, the second largest capacity, when piston in a stroke from position 2 run to highest distance position Y (when air-breathing on the contrary,
Position 2 is run to from highest distance position Y), compressor air suction and swept volume are less than maximum capacity at this time, but are also at larger
Capacity range, the refrigerant flow corresponded in refrigerator refrigeration system is relatively large, and refrigerating capacity is also relatively large；
3, the big capacity of N, when piston in a stroke from position N run to highest distance position Y (when air-breathing on the contrary, from
Highest distance position Y runs to position N), compressor air suction and swept volume are minimum at this time, the refrigeration in corresponding refrigerator refrigeration system
Agent flux is minimum, and refrigerating capacity is also minimum.
The whole refrigeration capacity variation of current frequency conversion refrigerator is all by environment temperature, set temperature, switch gate and is
Situations such as no defrost, carries out the variation of frequency to realize the variation of cooling capacity.And for using what is proposed in the present invention to pass through change
Capacity compressors and for realizing the adjustable amount of the turning cold refrigerator of refrigerator whole refrigeration capacity, be suitble to electricity the invention proposes a kind of
The control method that refrigerator is also suitble to Simple electronic refrigerator and mechanical refrigerator is controlled, and can realize energy-efficient purpose under full ambient engine,
