Illustrate the refrigerating plant 100 according to the utility model embodiment referring to Figure 11 and in conjunction with Fig. 1, Fig. 2 and Fig. 5
Operation principle.
The refrigerant for flowing through the second heat exchanger 2 flows to the first air entry 413 after overheat, that is, flows through the second heat exchanger 2
Refrigerant by the first air entry 413 enters the first working chamber 411 after being heated by environment temperature, and compressor operating is to sucking
Refrigerant is compressed, and refrigerant is discharged from first row gas port 414 after compression.And the gaseous coolant separated in flash vessel 3 passes through
Second air entry 4161 enters the second working chamber 412, by cold in the second working chamber of linear reciprocating motion pair 412 of slide plate 43
Matchmaker compresses, and refrigerant is discharged from second exhaust port 4162 after compression.
After the first working chamber 411 and the compression of the second working chamber 412 refrigerant that is discharged can in compressor internal mix,
This can be not particularly limited in compressor external mix, the utility model, mixed refrigerant flows to the first heat exchange together
Device 1 is condensed by being realized after the heat exchange of First Heat Exchanger 1；As shown in figure 11, the liquid refrigerants after heat exchange passes through first throttle member
Part 5 carries out being throttled to required intermediate pressure, and gas-liquid separation is then carried out in flash vessel 3, and the liquid refrigerants isolated reaches full
It is again introduced into the second restricting element 6 with state to throttle, is finally reached vapor pres- sure force value into being steamed in the second heat exchanger 2
Hair.
If refrigerating plant 100 is switched to including the above-mentioned such as four-way valve of control valve 7 and refrigerating plant 100 from refrigeration
When heat-production functions, second is flowed to after the refrigerant being discharged after the first working chamber 411 and the compression of the second working chamber 412 being mixed
Then heat exchanger 2 throttles through the second restricting element 6, the gas-liquid mixture after throttling flows to flash vessel 3 and detached, point
Gas from after is inhaled into the second working chamber 412 by the second air entry 4161 and is compressed, and liquid is then through first throttle member
Part 5 is evaporated after being throttled to evaporating pressure again into First Heat Exchanger 1, and the low-pressure gas after finally evaporating is after overheat
The first working chamber 411 is inhaled by the first air entry 413 to be compressed.
Optionally, the refrigerant in refrigerating plant 100 is at least one of HCFC, HFC, HC and HFO.
Hereby it is achieved that applying gas coolant injection mode on an individual cylinder 41, cylinder bore diameter is realized
The rolling rotor-type compression of the first working chamber 412 formed with roller outer diameter and 416 shape of sliding vane groove 416 and air valve mounting groove
At the second working chamber 412 the linear compression of slide plate, realize rolling rotor-type compression and sliding simultaneously on single cylinder compressor
The linear compression of piece, while promoting the efficiency of refrigerating plant 100 so that Compressor Manufacturing is simple, safe and reliable, and greatly
Cost is saved in ground.It is understood that may be multicylinder compressor according to the compressor of the utility model embodiment, wherein
A cylinder or multiple cylinders use the embodiments of the present invention technology.
Moreover, when refrigerating plant 100 has the function of two kinds of refrigeration and heating simultaneously and is applied to air-conditioning system, in room
In the case that internal-external temperature difference is big, heating capacity will be promoted significantly air-conditioning system at low ambient temperatures, can effectively reach user
Demand to heat.
According to the refrigerating plant 100 of the utility model embodiment, the requirement of high performance-price ratio can be met, and with manufacture
Simply, safe and reliable advantage.
In the cylinder assembly 44 of the utility model embodiment, as shown in fig. 7, fluted 421 are formed on piston 42, slide plate
43 head has protrusion 431, and 431 cooperation of protrusion is in groove 421, and the cornerite of groove 421 is α, and α meets：180 ° of α ＞.Example
Such as, as shown in fig. 7, groove 421 is inwardly concaved by a part for the periphery wall of piston 42 is formed, groove 421 is preferably arc groove,
The shape of protrusion 431 is preferably adapted with the shape of groove 421, as a result, by groove 421 and making 431 cooperation of protrusion
Groove 421 surrounds 180 ° of the angle [alpha] ＞ of protrusion 431, and slide plate 43 always will not be with piston when compressor operating can be effectively ensured
42 are detached from, will not gas leakage between the suction side and exhaust side so as to ensure the first working chamber 411.
Another embodiment according to the present utility model, as shown in figure 9, the head of slide plate 43 is equipped with magnet iron piece 432.By
This, when compressor is when starting to work, 43 tail portion of slide plate and gas pressure suffered by 43 head of slide plate are roughly equal, due to slide plate 43
Head is equipped with magnet iron piece 432, and piston 42 is to be made suitable for the material (for example, iron etc.) with 432 magnetic of magnet iron piece, so as to
Ensure that slide plate 43 contacts compressor with piston 42 on startup, ensures that compressor reliably operates.Specifically, 43 head of slide plate can be with
It is formed with the holding tank for accommodating magnet iron piece 432.
Further, as shown in figure 8, the inner end of slide plate 43 is equipped with spring 45.As a result, when compressor on startup, slide plate
43 tail portions and gas pressure suffered by 43 head of slide plate are roughly equal, by the way that spring 45, Ke Yibao is arranged in the second working chamber 412
Slide plate 43 is contacted with piston 42 when card starts, and ensures that compressor reliably operates.
