Embodiment
A kind of refrigeration system embodiment of the utility model is described further referring to figs. 1 to Fig. 2.
As shown in figure 1, this refrigeration system, mainly includes condenser 1 and evaporator 2, the output end of evaporator 2 is connected with Compressor 3, in condenser 1(High pressure)With evaporator 2(Low pressure)Junction has added the first fluid reservoir 4 and the second fluid reservoir 5(First The fluid reservoir 5 of fluid reservoir 4 and second should be reverse mounted during actual installation, is from the bottom up because liquid has quality), Compressor 3 is discharged refrigerant by high pressure, reaches heating effect by the radiating of condenser 1, then switchs 6 by first pressure, the One pressure switch 6 turns on the first fluid reservoir 4, closes the second fluid reservoir 5, while second pressure switch 7, closes the first fluid reservoir 4, Turn on the second fluid reservoir 5, refrigerant the first fluid reservoir 4 of entering compresses and liquefies, and pressure constantly increases in the first fluid reservoir 4, closed Hyperbaric environment under, refrigerant is sufficiently radiated and liquefied, while compressor 3 also inhales the refrigerant of the second fluid reservoir 5 Go out, reach refrigeration by evaporator 2.When pressure reaches the fully liquefied pressure of refrigerant, first pressure switch 6 and second After pressure switch 7 detects, first pressure switch 6 immediately closes off the first fluid reservoir 4, turns on the second fluid reservoir 5, while the second pressure Power switch 7 conducting the first fluid reservoirs 4, close the second fluid reservoir 5, such iterative cycles come reach refrigeration, heating effect.
As another embodiment, as shown in Fig. 2 in the case where above-mentioned technical proposal remaining structure is constant, by One fluid reservoir 4 and the second fluid reservoir 5 make a fluid reservoir into(That is the 3rd fluid reservoir 9), the 3rd fluid reservoir 9 includes tank body left part 91 With tank body right part 92, tank body left part 91 and tank body right part 92 are separated by piston 10, and piston 10 is right by tank body left part 91 and tank body The pressure difference in portion 92 can be moved freely, and piston 10 is shifted onto the low one end of pressure, first pressure switch 6 by the high one end of pressure The 3rd pressure switch 11 and the 4th pressure switch 12 of four-way are changed to second pressure switch 7(Also referred to as four-way pressure controller), Tank body left part 91 is connected by the first pipeline 13 with the 3rd pressure switch 11, and tank body right part 92 passes through the second pipeline 14 and the 4th pressure Power switch 12 is connected, and the 3rd pressure switch 11 and second pressure switch 7 are additionally provided with the He of the 3rd pipeline 15 for connecting both 4th pipeline 16, compressor 3 are discharged refrigerant by high pressure, reach heating effect by the radiating of condenser 1, then by the 3rd pressure Power switch 11, main pipeline turns on the first pipeline 13, and the 3rd pipeline 15 and the 4th pipeline 16 are closed in the end of the 3rd pressure switch 11, Second pipeline 14 at the end of the 4th pressure switch 12 turns on main pipeline simultaneously, closes the 3rd pipeline 15 and the 4th pipeline 16, refrigeration Agent enters tank body left part 91, and the pressure of tank body left part 91 is more than tank body right part 92, and piston 10 is shifted onto from tank body left part 91 by refrigerant Tank body right part 92, the refrigerant of tank body right part 92 absorb heat into evaporator 2 and reach refrigeration, and the refrigerant of tank body right part 92 is simultaneously By two power, one be tank body left part 91 pressure, one be compressor 3 air-breathing.When the pressure of tank body left part 91 reaches system Cryogen fully liquefied pressure when, after the 3rd pressure switch 11 and the 4th pressure switch 12 detect, immediately close off main pipeline with First pipeline 13, main pipeline turn on the 3rd pipeline 15, and the first pipeline 13 turns on the 4th pipeline 16, while the 4th pressure switch 12, the 3rd pipeline is turned on second pipe, and the 4th pipeline turns on main pipeline, and refrigerant is entered the fluid reservoir of tank body right part 92, tank The refrigerant of body left part 91 enters evaporator 2, so circulates to freeze, heats, the operation principle of this embodiment and above-mentioned skill Art scheme is identical, is all to allow the refrigerant one-in-and-one-out of tank body left part 91 and tank body right part 92 to exchange repeatedly, can equally allow system Cryogen is sufficiently radiated and liquefied, and is improved refrigeration, heating efficiency, is greatlyd save electric power resource(3rd pressure switch, Four pressure switches can also use four-way valve alternative, and opening for four-way valve is controlled using the sensing outside the movement of piston 10 and fluid reservoir Close, controlled using magnetic field induction, magnetic field induction switch is mature technology.Using the system more power saving of the 3rd fluid reservoir 9, but Control system ratio uses the first fluid reservoir 4, and the second fluid reservoir 5 wants complexity, can use different tank bodies according to different purposes, On the premise of the cost that practices every conceivable frugality, electric power resource is saved).
As preferable, second pressure switchs 7 output end openings of sizes and matched with the air inlet of compressor 3 and exhaust outlet, Purpose be in order that second pressure switch 7 size matched with the suction and discharge of compressor 3, refrigerant can be made fully to vaporize, carried High refrigeration, heating efficiency.
As shown in figure 1, second pressure, which switchs 7 output ends, is connected with expansion valve 8, expansion valve 8 can also equally play throttling Effect, but compare the more difficult blocking of more traditional refrigeration system using capillary, maintenance is more convenient, the basis of expansion valve 8 Various refrigeration plants need, and can select to install.
In above-mentioned technical proposal, pressure switch, expansion valve 8 are common knowledge, and those skilled in the art should be easy to Understand the technological means, therefore its structure is not elaborated in specification accompanying drawing.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
