Specific embodiment
In order to illustrate more clearly of the utility model, the utility model is done into one with reference to preferred embodiments and drawings
The explanation of step.Similar component is indicated with identical reference numeral in attached drawing.It will be appreciated by those skilled in the art that below
Specifically described content is illustrative and be not restrictive, and should not limit the scope of protection of the utility model with this.
The utility model provides a kind of specific embodiment of refrigerating plant, and the refrigerating plant includes：Natural cold group,
First heat exchange group 4 and the second heat exchange group 8；Include displacement liquid in the first heat exchange group 4 and the second heat exchange group 8；Definition substitution
The end that liquid is flowed out by the first heat exchange group 4 is the head end of the first heat exchange group 4, and it is that displacement liquid, which flows into the end of the second heat exchange group 8,
The head end of two heat exchange groups 8；The nature cold group is placed in the head end of the first heat exchange group 4；The refrigerating plant further includes：Even
Lead to the head end of the first heat exchange group 4 and the first pipeline of 8 head end of the second heat exchange group；And by displacement liquid by the second heat exchange
Group 8 flows into the second pipeline of the first heat exchange group 4.
Certainly, in the present embodiment, refrigerating plant further includes frequency-conversion control cabinet 13, unlatching and pass for refrigerating plant
It closes.
Refrigerating plant provided by the utility model makes full use of the natural cold wind 1 in winter, and electricity consumption is relatively low, with cold cost compared with
It is low and simple in structure, installation easy to process；Process of refrigerastion is not related to ammonia cycle simultaneously, and safety coefficient is higher, is not susceptible to quick-fried
Phenomena such as fried.
In addition, as shown in Figure 1, in order to increase the heat exchange area of heat exchanger, the first heat exchange group 4 is by multiple parallel connections
Heat exchanger connects to be formed, and heat exchanger can be pipe heat exchanger, as shown in the figure, each heat exchanger passes through unit inner circulating tube line 5
Connection.
Similarly, the second heat exchange group 8 is connected by the heat exchanger of multiple parallel connections forms, and heat exchanger can be pipe type heat transfer
Device.
Optionally, displacement liquid should be heat absorption quick heating, heat release cools down fast solution, the i.e. low solution of specific heat capacity, for
Economic consideration, present embodiment are preferably calcium chloride water.
Preferably, in order to provide buffering for the displacement liquid in heat exchange group, and prevent local overpressure excessive, the system
Device for cooling further includes the circulating box 11 on first pipeline, and 11 displacement liquids of circulating box provide buffering, when the first heat exchange
When flow is too fast in group 4, circulating box 11 is for slowing down water velocity, when water flows through slow in the first heat exchange group 4, due to circulating box
Accumulation has displacement liquid in 11, and therefore, water velocity will not be substantially reduced as derived from circulating box 11, be conducive to having in heat exchange group
Sequence exchanges heat.
Certainly, circulating pump 10 being also set up on first pipeline, the flowing for displacement liquid provides power, meanwhile, in order to examine
Testing temperature needs to place temperature monitoring probe 14-17 in different places in the present embodiment, which is used for
Measure the temperature of corresponding position.
In addition, as shown in Figure 1, in order to make heat exchange more abundant, hot-fluid should be set with cold flow adverse current, that is, natural cold wind 1
Wind turbine 2 should be entered by figure 1 route, natural cold wind 1 is blowed to the air-flow of right, i.e. cold wind 1 by wind turbine 2 by the left in figure
It flows to as from left to right, therefore, for heat exchange efficiency higher, the flow direction of the displacement liquid in the first heat exchange group 4 should be with this
On the contrary, i.e. in the first heat exchange group 4, the displacement liquid is flowed to air current flow direction by the tail end of the first heat exchange group 4
First heat exchange group, 4 head end, it is known in the art that the setting of above-mentioned adverse current avoids displacement liquid from directly being connect with the low-temperature region of cold flow
It touches, so as to reduce influence of the circumstance of temperature difference to displacement fluidity energy.
Similarly, in the ice model tank 7 of the periphery setting of the second heat exchange group 8,9 institutes that are marked in the flow direction such as figure of ice water
Show, ice water by ice water return pipe road 6 by ice model tank 7, then by 9 bleeder of ice water outlet pipeline outside, therefore, in order to enable
Displacement liquid in second heat exchange group 8 is with the water (flow) direction in ice model tank 7 on the contrary, the displacement liquid is by the second heat exchange group 8
Head end flows to 8 tail end of the second heat exchange group.
In practical operational process, by taking the Northeast as an example, the temperature of natural cold wind 1 is about -20 DEG C, and cold air exists
Enter the refrigerating plant under the action of wind turbine 2, and cold wind 1 from left to right is formed under the drive of wind turbine 2, while the first heat exchange group
Displacement liquid in 4 circulates, with after displacement liquid heat exchange, the temperature of cold air raising, and displacement liquid temperature is down to -4
DEG C, -4 DEG C of displacement liquid is further with the hydrothermal exchange in ice model tank 7, and the water temperature in ice model tank 7 is 8 DEG C, by further heat
After exchange, the water temperature in ice model tank 7 is down to 4 DEG C, is expected so as to reach cooling.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model, for those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways, all embodiments can not be exhaustive here,
It is every to belong to obvious changes or variations that the technical solution of the utility model is extended out still in the utility model
The row of protection domain.
