There are four types of operating conditions for tool in the whole device course of work:
Cold supply, dehumidification operating condition:
Heat pump system 001 is the Cooling and Heat Source of device;Refrigerant is sucked the steam heel row for being compressed into high temperature and pressure by compressor 1 Enter air-cooled condenser 4, to air heat release in air-cooled condenser 4, be condensed into highly pressurised liquid, then becomes low by expansion valve 3 The refrigerant of warm low pressure enters back into evaporator 2, and the heat for absorbing cold water is vaporized into the steam of low-temp low-pressure.It is above to complete one A refrigerative circle system.Wherein the axial flow blower 5 of 4 front side of air-cooled condenser takes away condensation heat, air by being sent into outdoor air It is directly entered regeneration module 6 after being heated to form high temperature air, contacts and goes forward side by side with low temperature weak solution in the packing layer of regeneration module 6 Row hot and humid area.High temperature air takes away the moisture content in weak solution and is cooled, and is finally discharged into atmosphere.It is dilute in regeneration module 6 Solution, which is then concentrated, is regenerated as high temperature concentrated solution.High temperature concentrated solution enters solution-solution heat exchanger 7 and low temperature weak solution carries out Heat exchange, using weak solution cooling capacity be pre-chilled, become the lower concentrated solution of temperature, subsequently enter solution-water- to-water heat exchanger 8, further by Total return water is cooled to low temperature concentrated solution, finally enters concentrated solution fluid reservoir 9.The low temperature concentrated solution come out from concentrated solution fluid reservoir 9 It is sent in the spray tube of 12 upper end of dehumidification module by concentrated solution pump 13, solution is by being sprayed in 12 packing layer of dehumidification module It is contacted with the fresh air being admitted to and carries out hot and humid area.Low temperature concentrated solution absorbs the vapor and heat in fresh air, becomes dilute molten Then liquid enters weak solution fluid reservoir 10 by 12 bottom solution slot of dehumidification module.Fresh air is then low temperature and low humidity by reducing temperature and humidity Air, after by surface air cooler 14 be further cooled to ventilation state point, be sent into finally by pressure fan indoor.Weak solution storage Solution in flow container 10 is then sent into solution-solution heat exchanger 7 by weak solution pump 11 to exchange heat with high temperature concentrated solution, after It is sent in the spray tube of 6 upper end of regeneration module, solution is by being sprayed at the hot-air in 6 packing layer of regeneration module and being admitted to It contacts and carries out hot and humid area.Cold water after the cooling of evaporator 2 is divided into two branches, and one is passed through indoor end to supply water, Another is then passed through surface air cooler 14.The return water of two branches is imported into total return pipe, and total return pipe is by solution-water heat exchange It is connect after device 8 with 2 arrival end of evaporator.Total return water exchanges heat in solution-water- to-water heat exchanger 8 with the concentrated solution being pre-chilled, will be dense Solution is cooled to low temperature concentrated solution.
Only cooling supply operating condition:
When outdoor temperature is higher, but does not need dehumidifying, concentrated solution pump 13 and weak solution pump 11 are closed, heat pump system is opened 001 and heat exchanger bypass valve.Open 14 He of regeneration by-pass line and surface air cooler between regeneration cabinet and air-cooled condenser 4 Dehumidifying by-pass line between dehumidifying cabinet, the hot air draft of air-cooled condenser 4 are directly discharged into atmosphere by regenerating by-pass line, newly Wind then passes through dehumidifying by-pass line and is directly bypassed to surface air cooler 14.The cold water come out from evaporator 2 is still divided into two branches, and one Part enters the room end, and a part enters the cooling fresh air of surface air cooler 14.Total return water then passes through heat exchanger bypass valve and is directly entered Evaporator 2.
Only remove wet cooling condition:
When outdoor temperature is convenient, but humidity is larger, heat pump system 001 and solution regeneration system are opened with example one at this time System 002 and fresh air treatment system 003.The high-temperature hot air of 4 side of air-cooled condenser regenerates solution at this time, and return water passes through molten Liquid-water- to-water heat exchanger 8 cools down concentrated solution.It is different from cold supply, dehumidification operating condition, while needing to close and being passed through indoor end The water supply branch of end device, the cold water for coming out evaporator 2 only enter 14 branch of surface air cooler.Pass through 002 He of solution regeneration system Fresh air treatment system 003 carries out cool-down dehumidification to fresh air, makes Fresh air handing to ventilation state point.
Only supplying thermal condition:
When outdoor temperature is lower, but humidity is suitable for, heat pump system 001 and heat exchanger bypass valve are opened, is closed dense molten Liquid pump 13 and weak solution pump 11.The high temperature and high pressure gas that compressor 1 is discharged is by four-way reversing valve conversion direction, into evaporation Device 2(at this time high-temperature high-pressure refrigerant in vaporizer side heat release) hot water preparing.Hot water is divided into two branches, and one is water supply branch End equipment is entered the room, another enters surface air cooler 14 and heat fresh air.Total return water then passes through heat exchanger bypass valve and is directly entered Evaporator 2.It needs to open regeneration by-pass line and surface air cooler 14 between regeneration cabinet and air-cooled condenser 4 at this time and removes wet tank Dehumidifying by-pass line between body, air-cooled condenser 4(at this time low-temp low-pressure refrigerant condenser side absorb heat) cold air draft It is discharged into atmosphere by regenerating by-pass line, fresh air then passes through dehumidifying by-pass line and is directly bypassed to surface air cooler 14, by surface air cooler 14 are heated to ventilation state point.
Finally, it should be noted that technical side the above examples are only used to illustrate the technical scheme of the present invention and are not limiting Case, those skilled in the art should understand that, modification or equivalent replacement of the technical solution of the present invention are made for those, and The objective and range for not departing from the technical program, are intended to be within the scope of the claims of the invention.
