Fig. 1 and Fig. 2 shows that the hypobaric and refrigerated preservation system of gloomy pump is exerted in a kind of use according to the preferred embodiment of the present invention
Structural schematic diagram, the hypobaric and refrigerated preservation system which exerts gloomy pump include air inlet pipe 1, humidifier 35, low pressure refrigerating chamber 2, first exert
Gloomy pump installation 6, exhaust pipe 7, indoor heat-exchanger rig 24, Confluent Flow valve 21, second exert gloomy pump installation 10, cooler 15, throttling
Valve 16 and dividing flow valve 17.With reference to Fig. 1, air inlet pipe 1 is used to import outside air, and an intake valve is provided in air inlet pipe 1,
For adjusting the flow of air.The import of humidifier 35 is connect with air inlet pipe 1, and the import of the air duct of low pressure refrigerating chamber 2
It is connect with the outlet of humidifier 35, outside air enters low pressure cold after humidifying by humidifier 35 and hides room 2, so that low pressure refrigerating chamber
The humidity of air is maintained within the scope of the optimum humidity of fruits and vegetables storage in 2, extends the preserving fruit and vegetable utilizing phase.The air of low pressure refrigerating chamber 2
The import in channel is provided with a check-valves, prevents the air blow back of low pressure refrigerating chamber 2 from returning in humidifier 35.Low pressure refrigerating chamber 2
The outlet of air duct air delivery is exerted to first by gloomy pump installation 6, and the air duct of low pressure refrigerating chamber 2 by exhaust tube 5
Outlet be provided with a vacuum valve 4, to adjust the vacuum degree of low pressure refrigerating chamber 2.
With reference to Fig. 2, first, which exerts gloomy pump installation 6, exerts gloomy pump group including at least one set first, and first exerts every group of gloomy pump installation 6
First exerts that gloomy pump group includes base station body 27 and at least one exerts gloomy pump, and base station body 27 is provided with a gas feed 28, a gas
Export 29, one cold flow import 36, a cold flow exports 37, one hot-fluid import 39 and a hot outlets 38.Each exerting gloomy pump includes
Cold chamber 30, hot chamber 31, porous interlayer 32 and interface channel 33 are separated between cold chamber 30 and hot chamber 31 by porous interlayer 32,
The aperture in the hole on porous interlayer 32 is not more than the molecule mean free path of air.Wherein, porous interlayer 32 is porous membrane,
It can be Bio-sil film, the edge of porous membrane is sealingly disposed in base station body 27 by sealing ring.Due to porous interlayer
The aperture in the hole on 32 is not more than the molecule mean free path of air, when the temperature of hot chamber 31 is higher than the temperature of cold chamber 30 to meet
When the condition of thermal transpiration effect occurs for air, the molecule of the air entered in cold chamber 30 will pass through porous interlayer 32 and be flowed into heat
In chamber 31, and because air molecule is assembled due to pressure rise in hot chamber 31, which achieves air to flow to high pressure from low-pressure state
State, i.e., hot chamber 31 vacuumize cold chamber 30.When the quantity for exerting gloomy pump that every group first is exerted gloomy pump group is one, cold chamber 30
Import is connect by interface channel 33 with gas feed 28, and the outlet of hot chamber 31 is connected by interface channel 33 and gas vent 29
It connects；When the quantity for exerting gloomy pump that every group first is exerted gloomy pump group is two or more, all gloomy pumps of exerting are exerted with previous
It is sequentially gone here and there by way of being connect the import for the cold chamber 30 that interface channel 33 exerts gloomy pump with the latter the outlet of the hot chamber 31 of gloomy pump
It is set in base station body 27 to connection, the import of first cold chamber 30 for exerting gloomy pump is connect with gas feed 28, the last one exerts gloomy
The outlet of hot chamber 31 of pump is connect with gas vent 29, when air sequentially by it is all it is concatenated exert gloomy pump after, be achieved that the
One, which exerts gloomy pump installation 6, vacuumizes low pressure refrigerating chamber 2.It is each provided in the every group first hot chamber 31 for exerting gloomy pump for exerting gloomy pump group
The hot-fluid pipeline of one hot chamber heat exchanger 13, each hot chamber heat exchanger 13 is sequentially connected in series, the heat of first hot chamber heat exchanger 13
The outlet in flow tube road is connect with the hot outlets 38 of base station body 27, the import of the hot-fluid pipeline of the last one hot chamber heat exchanger 13 with
The hot-fluid import 39 of base station body 27 connects；And be each provided in the every group first cold chamber 30 for exerting gloomy pump for exerting gloomy pump group one it is cold
The cold flow pipeline of chamber heat exchanger 19, each cold chamber heat exchanger 19 is sequentially connected in series, the cold flow pipeline of first cold chamber heat exchanger 19
Import connect with the cold flow import 36 of base station body 27, the outlet of the cold flow pipeline of the last one cold chamber heat exchanger 19 and base station body
Cold flow outlet 37 connection, the connection knot of hot-fluid pipeline and cold flow pipeline in the base station body 27 of gloomy pump group is exerted with every group first of simplification
Structure optimizes layout of beam line.Hot chamber heat exchanger 13 is set and cold chamber heat exchanger 19 is to more effectively generate and maintain hot chamber 31
With the temperature difference of cold chamber 30, it is ensured that generate more significant thermal transpiration effect, and cold chamber 30 is directly cold by the refrigeration working medium of the system
But, convenient and efficient, it does not need to introduce outer low temperature medium, simplied system structure.Because first exerts and exerts gloomy series connection of pumps in gloomy pump group
Quantity it is more, first exert gloomy pump group suction capactity it is stronger, the vacuum degree that low pressure refrigerating chamber 2 can reach is higher, so
First exert every group first quantity for exerting gloomy pump exerted in gloomy pump group of gloomy pump installation 6 according to 2 required pressure of low pressure refrigerating chamber come
It determines.
With reference to Fig. 1, when it is two or more that first, which exerts the quantity that the first of gloomy pump installation 6 exerts gloomy pump group, these
First exerts gloomy pump group connect with exhaust tube 5 in parallel, i.e., the gas feed 28 that each group first exerts gloomy pump group is connect with exhaust tube 5.
And these first exert that gloomy pump group is in parallel connect with exhaust pipe 7, i.e. the gas vent 29 and exhaust pipe 7 of exerting gloomy pump group of each group first
Connection is exerted gloomy pump group so as to which the air of low pressure refrigerating chamber 2 is conveyed to each group first respectively by exhaust tube 5, then is passed through
Exhaust pipe 7 is discharged into external environment, to achieve the purpose that pumped down.Wherein, first exert gloomy pump installation 6 first exert gloomy pump
The quantity of group can be determined according to the capacity of system requirements.Low pressure refrigerating chamber 2 imports air from the external world by air inlet pipe 1,
It is finally discharged into the external world by exhaust pipe 7 again, the size of room pressure is adjusted by the aperture of intake valve and vacuum valve 4,
So that low pressure refrigerating chamber 2 maintains under certain low-pressure state.Fruits and vegetables are saved under subatmospheric environment, to reduce
Oxygen concentration in storage environment reduces the respiration of cell, restrained effectively ethylene etc. and accelerates the ripening the generation of substance, and
And as storage environment is discharged in the harmful substance that pumping process can also distribute agricultural product in time, to substantially increase fruits and vegetables
The freshness date of equal agricultural product.
