Description
Technical field
Technical field of refrigeration equipment is the utility model is related to, more particularly to a kind of pressure apparatus Fast-Balance system.
Background technology
Panel-assembled cold store is typically that battenboard is built as a closed room in the market, and inside is empty during use
Gas completely cuts off with outside air.Generally, freezer internal-external temperature difference is larger, for freezer and guick freezing room, its indoor and outdoor temperature
Difference typically at 40 DEG C or so, sometimes sweltering heat date internal-external temperature difference up to nearly 60 DEG C in the case of, because storehouse temperature drop is low
Caused decrease in air pressure causes storehouse inside and outside larger compared with atm difference, easily causes freezer deformation or even bursts.Prior art
Pressure balance method be typically when freezer deforms after, be opened manually door and window or utilization pressure equaliser equilibrium air pressure.This
Kind mode effectively can not prevent freezer from deforming, and can not prevent cold intelligently in real time according to the factor self-balancing pressure such as weather
The situation that storehouse deforms by external and internal pressure difference.
Therefore, problem be present for of the prior art, a kind of monitoring external and internal pressure difference autobalance in real time of offer is provided badly
The technology of freezer pressure is particularly important.
Utility model content
The purpose of this utility model is to avoid weak point of the prior art and provide a kind of external pressure in monitoring in real time
The Fast-Balance system of power difference autobalance freezer pressure.
The purpose of this utility model is achieved through the following technical solutions：
Freezer rapid pressure equalization system, include intelligent controller, room pressure sensor, pressure outside sensor and
Bidirectional electric stop valve, interior sensor are installed on cool house internal, and pressure outside sensor is installed on the outside of freezer, indoor biography
Sensor and outdoor sensor connect with intelligent controller electric signal, bidirectional electric stop valve be installed on the centre of freezer wall and
Controlled and be opened and closed by intelligent controller, cool house internal and outside communicate when bidirectional electric stop valve is opened.
Preferably, the number of bidirectional electric stop valve is provided with two or more and controlled by intelligent controller and is opened and closed.
It is furthermore preferred that more than two bidirectional electric stop valves are uniformly arranged in the wall of freezer.
Preferably, the side of bidirectional electric stop valve outwardly is provided with air-cooler.
The beneficial effects of the utility model：
Freezer rapid pressure equalization system of the present utility model includes intelligent controller, room pressure sensor, outdoor
Pressure sensor and bidirectional electric stop valve, interior sensor are installed on cool house internal, and pressure outside sensor is installed on freezer
Outside, interior sensor and outdoor sensor connect with intelligent controller electric signal, and bidirectional electric stop valve is installed on cold
The centre of storehouse wall and by intelligent controller control be opened and closed, when bidirectional electric stop valve is opened, cool house internal and outside communicate.
The utility model detects the pressure of cool house internal and outside using pressure sensor respectively, and has intelligent controller to calculate pressure
Difference, after preset value is reached, intelligent controller sends instruction to bidirectional electric stop valve and opened, and makes freezer inner and outer air pressure quick flat
Weighing apparatus, prevent the situation of the deformation of freezer wall or even explosion from occurring, it is safe efficient.Meanwhile the system operates for 24 hours, inspection in real time
Survey the pressure differential of freezer indoor and outdoor, intelligence running, balance pressure result operating efficiency height.
Brief description of the drawings
The utility model is described further using accompanying drawing, but the content in accompanying drawing is not formed to of the present utility model
What is limited.
Fig. 1 is the structural representation of one embodiment of the present utility model.
Include in Fig. 1：
1 --- freezer, 2 --- intelligent controller, 3 --- pressure outside sensor, 4 --- room pressure sensor,
5 --- bidirectional electric stop valve.
Embodiment
The utility model is described in further detail with the following Examples.
Embodiment 1
Referring to Fig. 1, the rapid pressure equalization system of freezer 1 of the present embodiment includes intelligent controller 2, room pressure sensing
Device 4, pressure outside sensor 3 and bidirectional electric stop valve 5, interior sensor are installed on inside freezer 1, pressure outside sensor
3 are installed on the outside of freezer 1, and interior sensor is connected with outdoor sensor with the electric signal of intelligent controller 2, and bidirectional electric is cut
Only valve 5 is installed on the centre of the wall of freezer 1 and controls opening and closing by intelligent controller 2, the freezer when bidirectional electric stop valve 5 is opened
1 inside and outside communicates.
Embodiment 2
The main technical schemes of the present embodiment are substantially the same manner as Example 1, the feature not laid down a definition in the present embodiment, adopt
With the explanation in embodiment 1, no longer repeated herein.In the present embodiment, the number of bidirectional electric stop valve 5 is provided with two
Control above and by intelligent controller 2 and be opened and closed, and more than two bidirectional electric stop valves 5 are uniformly arranged on the wall of freezer 1
In wall.
Embodiment 3
The main technical schemes of the present embodiment and embodiment 1 or embodiment 2 are essentially identical, do not solve in the present embodiment
The feature released, using the explanation in embodiment 1 or embodiment 2, no longer repeated herein.In this implementation, bidirectional electric is cut
Only the side of valve 5 outwardly is provided with air-cooler.The internal-external temperature difference of freezer 1 is larger, and gas pressure when temperature is low reduces, because
If directly flowing directly into 1 outer temperature of freezer higher other in freezer 1 not only temperature can raise and can not reach cold in freezer 1
Hide and require and the air pressure also rapid decrease when subsequent freezer 1 reduces temperature, the present embodiment in bidirectional electric stop valve 5 outwardly
Side is provided with air-cooler, and cold wind is introduced in freezer 1, can realize the purpose of rapid pressure equalization, and ensure that freezer 1
Refrigerated storage temperature need, pressure is more stable.
Finally it should be noted that above example is merely to illustrate the technical solution of the utility model explanation rather than to power
The limitation of the claimed scope of profit.One of ordinary skill in the art should be appreciated that with reference to preferred embodiment and can be to this reality
Modified with new technical scheme or equivalent substitution, but belong to the substantially identical of technical solutions of the utility model and protection
Scope.
