Thick mouthful of end of the throttling reducing transformer of moulding is import, and thin mouthful of end is outlet.The use of throttling reducing transformer has substituted cooling modules such as heating power expansion valve commonly used in conventional freezers and ejector.According to law of conservation of energy, the total energy of refrigerant carbon dioxide is a kinetic energy, in can and be invariable, when in the throttling reducing transformer, flowing, because the resistance of pipeline can consume a large amount of kinetic energy, while is according to the refrigeration law of conservation of fluid, the mass flow of importing and exporting at the throttling reducing transformer is identical, owing to import slightly exports carefully, so the flow velocity of outlet is greater than the flow velocity of import department, that is to say that cold-producing medium is through it can be converted into kinetic energy in most of behind the throttling reducing transformer, the interior of cold-producing medium can be reduced, reduce the temperature of cold-producing medium self, make liquid carbon dioxide in the throttling reducing transformer, reduce the purpose that pressure forms the low temperature gas-liquid mixture thereby reach.
As refrigerated dehumidification equipment, adopt preferentially that ODP is 0, GWP is that 1 carbon dioxide is made cold-producing medium, in addition, carbon dioxide also has incombustible, not combustion-supporting characteristic, therefore be more suitable for using in the down-hole, it can directly extract in atmosphere, also atmosphere pollution not after the discharging.Refrigerant carbon dioxide is with liquid high voltage style access arrangement, control the flow of its access arrangement by control valve, in the throttling reducing transformer according to fluid reducing to below the critical pressure value in pipeline along stroke pressure loss principle pressure, partially liq is vaporized at this, can be converted into kinetic energy in the cold-producing medium major part, the interior of cold-producing medium can be reduced, reduce the temperature of cold-producing medium self, thereby make liquid carbon dioxide in the throttling reducing transformer, reduce pressure and form the low temperature gas-liquid mixture, flow to evaporimeter.Low temperature saturated air liquid mixture with high velocity stream in evaporimeter, the liquid carbon dioxide of vaporization is not vaporized fully at this in evaporimeter, absorb a large amount of heat, the fin by evaporimeter reaches gas to heat from the space at evaporimeter place, and ambient air temperature is reduced.Because the fin temperature of vaporization heat absorption evaporimeter is extremely low, airborne moisture is met condensation at this and is formed the humidity that the globule reduces air, and the globule flow in the water receiving tank of casing along fin; Cryogenic gas after the vaporization continues to flow in the pipeline of evaporimeter, constantly absorbs heat simultaneously, constantly makes airborne hydrogenesis, and is identical with environment temperature until gas temperature; Gas is after temperature raises, flash-pot flows out and enters pneumatic blower fan, at this moment the pressure of gas is greater than atmospheric pressure, can drive the blower fan rotation by gas is mobile endlessly with pressure, make the circulation of air in the device, in time with humiture gas bleeder to reduce all, the gas make-up that humiture is higher is to evaporimeter, to improve the heat exchanger effectiveness of evaporimeter, the gas communication of the air push space outerpace of while bleeder.After liquid carbon dioxide is used up, also have the carbon dioxide of part gaseous state in the bottle, these gases are through the throttling reducing transformer time, pressure is undergone mutation, gas temperature is also reduced, and cryogenic gas carries out interchange of heat by evaporimeter and surrounding environment after entering evaporimeter, and equipment is worked on; Gaseous carbon dioxide only uses under the state of emergency after liquid carbon dioxide runs out, but the consumption of gaseous carbon dioxide is very big, can quicken the consumption of gas.
