Cold-producing medium is mainly used in high-temperature air conditioner, high temperature drying heat pump, the refrigeration of the high condensation temperature of high-temperature-hot-water heat pump
In system.
Drying heat pump application operational factor:
Principle is as follows:
Different types of mix refrigerant has different thermophysical propertys, and this will be that preferably providing for cold-producing medium is larger
Leeway.For the refrigeration system of a certain fixation, under its optimal operating condition, it is desirable to which cold-producing medium must have specific ermal physics
Property.The different azeotropic refrigerant of reasonable selection makes it meet this specific thermophysical property, it is possible to improve refrigeration
The thermodynamic efficiency of system, so as to reach the effect of energy-conservation.
Because azeotropic refrigerant reduces can condensing pressure, and while evaporating pressure raise, so in condensation temperature
In the case of constant with evaporating temperature, the pressure ratio of compressor will reduce, so that the lower power consumption of compressor.Therefore obtain same
Less work(is just only needed during the refrigerating capacity of sample.The rising of evaporating pressure simultaneously can reduce the vacuum of evaporimeter, make evaporimeter more
Stably work, and the reduction of condensing pressure can be such that condenser goes on a long journey in the state of safer.The refrigeration expert C.P.A of India
In the paper that RORA is delivered in the 15th International Institute or Refrigeration, agree by taking azeotropic refrigerant R22/R12 (85/15) as an example
This effect is determined.Due to the reduction of pressure ratio, the volumetric efficiency of compressor is improved, and refrigerating capacity increases, and the coefficient of performance is improved,
Simultaneously the motor temperature of compressor is also reduced to 70.3 DEG C from 87.5 DEG C, and the temperature of electric motor starting coil drops to 58.3 from 97.3 DEG C
DEG C, the safe handling to air-conditioner has played important effect.
Reduce can the delivery temperature of compressor using azeotropic refrigerant, it and the close phase of the property of cold-producing medium
Close.Research has shown that the thermal capacitance of cold-producing medium is bigger or adiabatic exponent is less, then the delivery temperature of compressor is lower.Cold-producing medium
The thermal capacitance of R115, R114, RC318 is all very big, and they have as the component of mix refrigerant reduces compressor exhaust temperature
Ability.If azeotropic refrigerant R22/R115 (48.8/51.2) is in the case of 44 DEG C of condensation temperature, -12 DEG C of evaporating temperature,
Its delivery temperature is 108 DEG C, and adopts unitary system cryogen R22, and its delivery temperature is 133 DEG C;When adopting R12 delivery temperature for
112℃。
In evaporation and condensation, temperature and gas-liquid phase composition are continually changing mixed non-azeotropic refrigerant, just because of
Its temperature change in evaporimeter and condenser, realizes non-isothermal heat exchange in evaporimeter and condenser, shows it certainly
The characteristics of energy saving of oneself uniqueness.
There is the mixing of each component and segregation phenomenon in phase transition process in mixed non-azeotropic refrigerant.Condensation process is height boiling
The condensation of point component and the process of low boiling component dissolving.Wherein each component should release the latent heat of liquefaction of oneself and release mixing again
Heat, the condensation heat for finally making unit cold-producing medium increases.And evaporation process is low boiling component desorption and high boiling component evaporation
Process, now each component will also absorb corresponding heat of dissociation in addition to the respective latent heat of vaporization is absorbed, as a result make unit cold-producing medium
Caloric receptivity is that refrigerating capacity increases.This is that refrigeration system increased refrigerating capacity in the case where power consumption is not increased.While cold-producing medium
Refrigerating effect per unit swept volume also accordingly improve.Research shows, after mixed non-azeotropic refrigerant, refrigeration system is significantly reduced
Energy consumption.
Such as R22/R114 (50/50) mixed non-azeotropic refrigerant replaces R22 to be used for heat pump, and coefficient of refrigerating performance improves 25%,
R22/R11 (50/50) replaces after R12 in refrigerator, lower power consumption 20%.
Mixed non-azeotropic refrigerant is made into differentia influence non-azeotrope mixing system in phase transition process between its gas phase and liquid phase
The thermodynamic property of cryogen.The gas phase occurred in phase transition process and the notable difference of the composition of liquid phase make non-azeotrope hybrid refrigeration
The each component of agent is easier to mix and separates, so as to reach the purpose for adjusting mixing ratio.Some civil air conditions, in annual fortune
Between the departure date, extraneous changes in environmental conditions is quite big, the air-conditioner of conventional use of unitary system cryogen, such as unitary system cryogen R22
Scope of application very little, its performance indications under a certain specific weather condition is very good.And performance refers to when weather conditions change
Mark will decline.Mixed non-azeotropic refrigerant because during its phase transformation proportioning change therewith, it is stronger to the adaptability of variable parameter operation,
The concentration of cold-producing medium each component can be adjusted according to weather conditions change.R22/R13B1 is such as used, in cooling in summer, with
High concentration R22 is run, with the operation of high concentration R13B1 when heating in the winter time.After this mixed non-azeotropic refrigerant, air-conditioner
Whole year can be run under higher thermodynamic efficiency, with significant energy-saving effect.
In addition, can realize that Lorenz is circulated using mixed non-azeotropic refrigerant, its heat absorption mean temperature is higher, and heat release is put down
Temperature is relatively low, therefore with higher Carnot efficiency.When cold-producing medium works under the temperature-variable heat source for being given, in theory can be with
The inverse Carnot cycle realized, for inverse circulation is kind of refrigeration cycle, the corresponding inverse Carnot cycle of Lorenz recycle ratio saves work(.
R134a proterties purposes:R134a does not contain chlorine atom, and to atmospheric ozone layer destruction is not played;With good peace
Full performance(It is nonflammable, do not explode, it is nontoxic, without excitatory without corruption);The heat transfer property of R134a relatively, so refrigeration system
The remodeling of system is easier.The heat transfer property of R134a is better than R12, is the substitute of R12.Therefore the consumption of cold-producing medium can be significantly
Reduce.It is at normal temperatures colourless gas, is colourless transparent liquid under pressure itself.
