Description
Technical field
The utility model relates to a kind of hydrojet enforcing condensation refrigeration system.
Background technology
A complete refrigeration system must comprise compressor, condenser, throttling arrangement and four basic elements of character of evaporimeter.Concrete kind of refrigeration cycle flow process is: the gaseous refrigerant of low-temp low-pressure is sucked from evaporimeter by compressor, enter condenser after being compressed into the gas of HTHP, in condenser to the cooling medium heat release, warm highly pressurised liquid in being condensed into, after throttling arrangement throttling step-down, become the gas-fluid two-phase mixture of low-temp low-pressure, and entering evaporimeter continuation heat absorption evaporation, the low-temp low-pressure gas of evaporation back formation is sucked by compressor once more.Like this, cold-producing medium is finished a kind of refrigeration cycle through pervaporation, compression, condensation, four basic processes of throttling in system.
The heat transfer process of cold-producing medium in condenser is divided into gas cooled, condensation, liquid and crosses cold three phases.After the overheated gas of the HTHP of discharging from compressor enters condenser, at first be cooled to saturation state (promptly discharging the process of sensible heat), just begin condensation process (promptly discharging the process of latent heat of phase change) then.Water-cooled cold water (heat pump) unit that with R22 is cold-producing medium is an example, and under operating mode commonly used, its condensation sensible heat accounts for 15%～30% of full heat (full heat=sensible heat+latent heat).Wherein the heat exchange efficiency of the cooling heat transferring of superheated refrigerant gas will be much smaller than the heat exchange efficiency of phase-change heat-exchange, therefore account for complete hot 15%～30% sensible heat in order to discharge, need take 25%～50% condenser heat exchange area, i.e. the existence of sensible heat part has reduced the whole heat exchange efficiency of condenser.
In the refrigeration system, generally adopt restricting elements such as choke valve or capillary to make high-pressure refrigerant through irreversible constant-enthalpy process decrease temperature and pressure, pressure can be converted into heat energy and total loss, causes the liquid flashes after the throttling.Water-cooled cold water (heat pump) unit that with R22 is cold-producing medium is an example, and under operating mode commonly used, the liquid flashes amount is about 18%～32% after the throttling, also is to say to have 18%～32% refrigerating capacity to slattern when throttling in the system approximately.
