Second, the regenerator component that the present invention adds can also rationally improve compressor suction in compressor tolerance range
The gas degree of superheat improves compressor exhaust temperature in the case where keeping evaporating pressure and constant condensing pressure, and there is condenser to make
The steam superheat of dehumidification heat exchange entrance refrigerant also increases accordingly.Since superheated steam convection transfer rate is much smaller than
Two-phase section cooling energy recovery, therefore condenser refrigerant pipeline overheat segment length accounts for total length ratio and will significantly improve, and has
The dehumidification heat exchange volume mean temperature of condenser effect and its desiccant mean temperature of surface coating will also significantly improve, together
When also will to occur therewith the air themperature of caloic exchange and increase, relative humidity reduces.According to Conventional solid desiccant material
The characterization of adsorption of (silica gel, zeolite molecular sieve, active carbon etc.), the raising of temperature and all will lead to drying with the reduction of relative humidity

Water reduces, and desorption performance is obviously improved.After the switching of system operating path, the dehumidification heat exchange with condenser effect changes
For the dehumidification heat exchange with evaporator effect, the desiccant on surface is used to adsorb the vapor in fresh air.According to described normal
The characterization of adsorption of solid drying material (silica gel, zeolite molecular sieve, active carbon etc.) is advised, desiccant adsorbs speed when water content is smaller
Rate is larger, therefore the lower desiccant of water content can adsorb more vapor in adsorption process after desorption stage, that is, be
The latent heat processing capacity of system significantly increases.
