Description

The double dehumidify evaporimeters of two-stage are double except wet condenser dehumidifying heat pump and method
Technical field
The present invention relates to being a kind of system of solid dehumidifying technical field of air-conditioning heat pumps, in particular it relates to which a kind of two-stage is double Dehumidify evaporimeter is double except wet condenser dehumidifying heat pump.
Background technology
Decoupling type solid dehumidifying air-conditioning technical handles the latent heat load in air using drier, and sensible heat load is then by certainly Right low-temperature receiver or conventional compression formula refrigeration system are handled, and system realizes sensible heat load and the separated processing of latent heat load and independence Control, overcomes the limitation that compressed air conditioner technology focuses on load.But except wet stock is discharged during solid dehumidifying Heat of adsorption, can not only increase the sensible heat load that need to subsequently handle, can also cause the rise of dehumidizer regeneration temperature.Based on evaporation Regenerative evaporation is cooled down the chilled water produced and introduces dehumidification heat exchange by the circulation of cold dehumidification heat exchange in cooling, by cold in pipe Freeze water process sensible heat load and heat of adsorption.But the cooling limit of such system is outdoor air wet bulb temperature, system processing is aobvious Thermic load it is limited in one's ability.Steamed based on the dehumidification heat exchange circulation that refrigerant is cooled down using the dehumidifying for being coated with desiccant material Hair/condenser replaces the evaporator/condensers in the circulation of conventional compression formula, and interior sink temperature is reduced and dry by refrigerant evaporation The adsorption temp of drying prescription, hot humidity load disposal ability gets a promotion.But after dehumidify evaporimeter dry tack free agent adsorption saturation, The interior low-temperature receiver of low temperature can then bring dehumidify evaporimeter surface condensation problem, the aqueous water of generation can to coating drier physical property and after Continuous regeneration produces greatly adverse effect, causes unstability and the decline of overall cycle performance.
Retrieve and find through the open source literature to prior art, to solve the above problems, Y.D.Tu etc. is in Scientific The Comfortable delivered on Reports, high-efficiency heat pump with desiccant-coated, When water-sorbing heat exchangers (2017,7,40437) are by controlling evaporation dehumidifying and condensing the switching of regeneration Between avoid the generation of condensation, but frequently switching can cause integral circulating heat power performance to be constantly in cold and hot dynamic alternation In, while the thermal resistance of big thermal capacitance Metal Substrate causes drier absorption and the reduction of desorption ability, so that overall cyclicity again It can decline.
