(1) steam compression type refrigerating
(2) absorption refrigeration
(3) vapour injection formula refrigeration
(4) gas expansion type refrigeration
(5) thermoelectric cooling
In above-mentioned refrigerating method, vapor compression refrigeration is most economical and most widely used refrigeration modes, also be the refrigeration modes of normal use in the testing equipment when things come to a head at the last moment, its principle is to utilize evaporation of liquid latent heat such as freon to absorb heat from the object that is cooled and realize refrigeration.Enter the liquid of evaporator through the expansion valve throttling, from object on every side, draw evaporation latent heat and evaporate, becoming the low temperature cooled compressor of body of calming the anger after the evaporation sucks, become high temperature and high pressure gas after the compressed machine compression and enter water-cooled or air-cooled condenser, be cooled to highly pressurised liquid therein, enter evaporator through expansion valve again.Circulation and so forth realizes refrigeration from the low temperature heat absorption, heat is discharged from high temperature again.
In refrigeration cycle, a variation that is become another state by a certain state is called as a process.Refrigeration cycle has four processes.Four processes in the refrigeration cycle are chatted in following letter.
(1) evaporation process:, in evaporator,, and increase its mass dryness fraction gradually from the surrounding medium absorption refrigeration by the low pressure wet steam after the expansion throttling.Like this, the gas that comes out from evaporator has just become dry saturation vapor or slightly the superheated vapor of the degree of superheat has been arranged.In evaporation process, refrigerant temperature and pressure remain unchanged.
(2) compression process: finish the steam that comes out from evaporator behind the refrigeration and enter refrigeration machine, after overcompression, temperature and pressure sharply raises.So the gas that refrigeration machine is discharged has just become the bigger heat steam of the degree of superheat.In the compression process, the cold-producing medium entropy is constant.
(3) condensation process: from the High Temperature High Pressure superheated vapor that refrigeration machine is discharged, carry out heat interchange with chilled water or air after entering condenser, make superheated vapor become saturated vapor gradually, and then become saturated liquid.When using water quench, saturated liquid temperature will continue to reduce, and occur cold.Pressure remains unchanged in the condensation process.
(4) throttling process: the liquid that comes out from condenser passes through throttling devices such as expansion valve or kapillary by throttling, becomes the wet steam of low-temp low-pressure, and the cold-producing medium enthalpy is constant in the throttling process.
Above-mentioned four cyclic processes are constantly circulation successively, and then reaches the refrigeration purpose.
For finishing each thermodynamic process of refrigeration cycle, compressor, heat interchanger, pipeline, pipeline fittings etc. need be formed a system, this system is called refrigeration system.
The single-stage compression refrigeration, be meant refrigerant vapour only through once compression, its minimum evaporating temperature can be controlled at-30 ℃～-40 ℃, when needs obtain lower test temperature, usually adopt the cascade refrigeration system, be about to two single-stage compression refrigeration system overlappings together.One of them system is a high-temperature part, warm cold-producing medium in the employing; Another system is the low temperature part, adopts low-temperature refrigerant.The condenser overlapping of the evaporator of high-temperature part and low temperature part constitutes condenser/evaporator.
