Abstract
The utility model discloses a natural wind circulation system for an underground cold storage, comprising a cold storage main body installed on a base in a concrete foundation, wherein a floor for closing the concrete foundation is arranged on the concrete foundation. The natural wind circulation system for the underground cold storage is characterized in that a vent is formed at the bottom of the cold storage main body, an air inlet channel controlled by a valve is formed on the north vertical surface of the concrete foundation, an air outlet is formed on the south vertical surface of the concrete foundation, and the air outlet is controlled by a valve and communicated with an air inducing channel. The natural wind circulating system for the underground cold storage has the following advantages: by utilizing the natural characteristic that the underground temperature of the north is constant in summer while air in winter is cold, the device is closed in summer and better outer layer heat insulation is provided for the cold storage main body by the more constant underground low temperature, and the valves for the air inlet and air outlet of the device are opened in winter to be passed through by the cold air so as to provide a low-temperature outer layer environment for the cold storage main body; therefore, energy consumption caused by heat insulation and temperature difference change is saved, and the present policy demands of energy conservation and emission reduction are satisfied; and the system has a great popularization and application value.
Description
Technical field
The utility model belongs to the heat preservation technology category of the freezer in the refrigerating fresh-keeping technical field, and definite saying is a kind of underground cold storage natural wind circulatory system.
Background technology
Present freezer no matter be freezer or freezer, all needs to be incubated.At present more common technology be on the interior or exterior wall of freezer, foaming is set polyurethane material as heat-insulation layer, like this, can guarantee all has good heat insulation effect under various conditions.But, in the north, the cold air of wintry weather cold is natural low-temperature receiver, and summer, that the temperature of underground certain depth keeps again substantially is constant (with Shandong Province's Qingzhou City is example: about 35～45 ℃ of summer high temperature surface temperature, and subsurface temperature is greatly in 20 ℃ scope, and the winter air minimum temperature is generally at 0～15 ℃), come freezer is incubated processing if can make full use of the temperature difference of this part nature, just can save a large amount of artificial energy sources.For this reason, designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Summary of the invention
Goal of the invention of the present utility model promptly provides a kind of underground cold storage natural wind circulatory system for the effect that the insulation that overcomes present freezer can not get the natural thermal insulation that the temperature difference in winter and summer brings puts forward.
Technical solution of the present utility model is to realize like this, this underground cold storage natural wind circulatory system, has the freezer main body on the basis in the concrete foundation of being installed in, the floor that has the closed concrete basis above the concrete foundation, it is characterized in that below the freezer main body, having air vent, the northern facade of concrete foundation has the air inlet duct by valve control, has air outlet at the south elevation of concrete foundation, and this air outlet is communicated with by valve control and with wind channel.Such structure has promptly realized the purpose of this utility model.
Beneficial technical effects of the present utility model is: adopt north subsurface temperature in summer more constant, and the physical feature of winter air cold, seal in summer by this device, with underground more constant low temperature is that the freezer main body provides outer preferably insulation, the valve of opening the inlet and outlet of this device winter makes cold air pass through, and is embodied as the outer environment that the freezer main body provides lower temperature.Thereby save owing to the energy resource consumption that is incubated and difference variation is brought, meet the policy requirements of current energy-saving and emission-reduction, have great application value.
Description of drawings
Accompanying drawing is the section schematic views according to freezer main body horizontal section of the present utility model.Sequence number in the accompanying drawings is expressed as: 1, concrete foundation, 2, air vent, 3, the freezer main body, 4, air inlet duct, 5, valve, 6, the floor, 7, air outlet, 8, valve, 9, wind channel.
The specific embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, the described underground cold storage natural wind circulatory system, has the freezer main body (3) on the interior basis of concrete foundation of being installed in (1), the floor (6) that has the closed concrete basis above the concrete foundation, it is characterized in that below the freezer main body, having air vent (2), the northern facade of concrete foundation has the air inlet duct (4) by valve (5) control, has air outlet (7) at the south elevation of concrete foundation, and this air outlet is communicated with by valve (8) control and with wind channel (9).Such structure, concrete foundation can be designed as square-section as shown in drawings, also can be designed as the cross section of circular arc interface or other shapes, can build accessory buildings such as control room, operation room on concrete foundation.In use, be installed on underground freezer main body and be installed on underground in the concrete foundation space and have on the basis of air vent, have certain space on every side to make things convenient for flowing of air.When summer; can be with the valve closing between air inlet duct and air outlet and the wind channel; outdoor on the ground air and the air in the buried concrete basis can not form convection current; air in the underground concrete foundation keeps and the beneath essentially identical temperature of temperature in ground; simultaneously the freezer main body has been formed certain low-temperature protection, reduced owing to keep the energy resource consumption that summer, heat radiation brought.When winter, with the valve open between air inlet duct and air outlet and the wind channel, shown in the dotted line in the accompanying drawing.The north ground lower temperature cold air of facade enters into concrete foundation inside through air inlet duct, and the top of process air vent and freezer main body is pooled to air outlet and forms convection current through wind channel, discharges at south elevation from wind channel at last.Cold air forms the effect of a cooling to the freezer main body, thereby has reduced the refrigerating capacity of freezer main body.Can realize energy saving purposes by structure of the present utility model and concrete operation with summer like this, in the winter time.Calculate with 30 cubic metres of volume freezers, adopt of the present utility model device according to meter on 300 day working day every year, and the more conventional identical scale freezer of the annual operation electricity charge is saved 15-25%, saves various kinds of equipment maintenance cost 20-30% simultaneously.
