Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is the schematic diagram that the present invention is applied to an exemplary embodiments of vapour compression refrigeration system;
Fig. 3 is the schematic diagram that the present invention is applied to another exemplary embodiments of absorption system.
Detailed description of the invention
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Cooling cycle system can be divided into steam compression type refrigeration to circulate and Absorption Cooling System.In the middle of prior art, no matter be steam compression type refrigeration circulation, or Absorption Cooling System, all be provided with evaporimeter, its concrete function is also consistent, namely realize refrigerant liquid in evaporimeter with cooled object generation heat exchange, absorb the heat of cooled object and vaporize.Heat pipe circuit of the present invention, namely builds based on this evaporimeter.
As shown in Figure 1, evaporimeter 1 is communicated with refrigerant line.In the middle of its external refrigerant line of interface 11 institute, cold-producing medium is gaseous state, and in the middle of the external refrigerant line of interface 12 institute, cold-producing medium is liquid.Cold-producing medium enters evaporimeter 1 by interface 12, is flowed out after vaporization by interface 11.
As shown in Figure 1, the external refrigeration system gas circuit valve 3 of interface 11 and heat pipe circuit gas circuit valve 21.Interface 12 external refrigeration system fluid path valve 4 and heat pipe circuit fluid path valve 22.Refrigerant line in evaporimeter 1 is connected into refrigerating circulation of the prior art by refrigeration system gas circuit valve 3 and refrigeration system fluid path valve 4.This kind of refrigeration cycle can be steam compression type, also can be absorption.
As shown in Figure 1, between the interface 11 of evaporimeter 1 and interface 12, except being connected except refrigerating circulation by refrigeration system gas circuit valve 3 with refrigeration system fluid path valve 4, be also parallel with by heat pipe circuit gas circuit valve 21, heat pipe circuit fluid path valve 22, and the heat pipe pipeline 2 that separate heat pipe 23 forms.This heat pipe pipeline 2 forms heat pipe circuit jointly with evaporimeter 1.
Fig. 2 and Fig. 3 is the two exemplary embodiments schematic diagrames that the present invention is applied to vapour compression refrigeration system and absorption system respectively.
As shown in Figures 2 and 3, when enclosed environment and outside atmosphere circumstance of temperature difference less time, such as be less than 10 DEG C, heat pipe circuit gas circuit valve 21 and heat pipe circuit fluid path valve 22 are all closed, simultaneously, refrigeration system gas circuit valve 3 and refrigeration system fluid path valve 4 are all opened, and evaporimeter 1 accesses in conventional refrigeration cycle, and provides cold to user.This kind of refrigeration cycle can be steam compression type, also can be absorption.
As shown in Figures 2 and 3, when enclosed environment and outside atmosphere circumstance of temperature difference larger time, such as be greater than 10 DEG C, heat pipe circuit gas circuit valve 21 and heat pipe circuit fluid path valve 22 are all opened, and meanwhile, refrigeration system gas circuit valve 3 and refrigeration system fluid path valve 4 are closed, evaporimeter 1 and separate heat pipe 23 form a closed-loop path, cold-producing medium evaporates and absorbs heat in evaporimeter 1, and in separate heat pipe 23, heat is released in condensation, and evaporimeter 1 provides cold to user.
When heat pipe circuit is closed, evaporimeter 1 runs with endless form such as the both vapor compression of routine or absorptions; When conventional refrigeration cycle loop is closed, heat pipe circuit is opened, and at this moment the evaporimeter 1 of original refrigeration system plays the effect of the evaporimeter of heat pipe, and separate heat pipe 23 mainly plays condenser effect.Flow separate heat pipe 23 from evaporimeter 1 steam out, condensation, and then get back to evaporimeter 1.
In another exemplary embodiments of the present invention, compression-type refrigerating system as shown in Figure 2, can run the part of separating heat tube 23 as conventional compact refrigerant system condenser.In part load region, make condenser and separate heat pipe 23 cooperation of original compression refrigerating system, reach the effect expanded working region and improve operational efficiency.As shown in Figure 2, now refrigeration system gas circuit valve 3 and refrigeration system fluid path valve 4, and heat pipe circuit gas circuit valve 21 and heat pipe circuit fluid path valve 22 are opened simultaneously.The condenser of compression-type refrigerating system and separate heat pipe 23 parallel running.
For the system providing refrigeration demand throughout the year, enclosed environment and outside atmosphere circumstance of temperature difference larger time, utilize separate heat pipe loop directly to environment release heat can provide enough colds.In this case, not only the operation of refrigeration system is simple and reliable, and due to the blower fan of main energy sources consumption required for separate heat pipe and environment heat exchange or water pump, so greatly can reduce operation energy consumption, reduces operating cost.In the middle of some compression-type refrigerating system, heat pipe pipeline 2 and the condenser cooperation of compression refrigerating system, reach the effect expanded working region and improve operational efficiency.Further, because the present invention is applicable to vapour compression refrigeration system and absorption system simultaneously, there is very high promotional value.
