There are four kinds of operating modes in the whole device course of work：
Cold supply, dehumidification operating mode：
Heat pump 001 is the Cooling and Heat Source of device；Refrigerant is sucked the steam heel row inlet air for being compressed into HTHP by compressor 1
Cool condenser 4, to air heat release in air-cooled condenser 4, is condensed into highly pressurised liquid, and it is low to be then changed into low temperature by expansion valve 3
The refrigerant of pressure, enters back into evaporator 2, and the heat for absorbing cold water is vaporized into the steam of low-temp low-pressure.A system is completed above
SAPMAC method process.The axial flow blower 5 of the wherein front side of air-cooled condenser 4 takes away condensation heat by sending into outdoor air, and air is added

002 and fresh air treatment system 003.Now the high-temperature hot air of the side of air-cooled condenser 4 regenerates to solution, and backwater passes through molten
Liquid-water- to-water heat exchanger 8 is cooled down to concentrated solution.It is different from cold supply, dehumidification operating mode, while needing closing to be passed through indoor end
The water supply branch road of end device, makes the cold water that evaporator 2 comes out only enter the branch road of surface cooler 14.Pass through the He of solution regeneration system 002
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 relatively low, but humidity it is suitable when, open heat pump 001 and heat exchanger bypass valve, close concentrated solution pump
13 and weak solution pump 11.The high temperature and high pressure gas that compressor 1 is discharged are by four-way reversing valve conversion direction, into evaporator 2
（Now high-temperature high-pressure refrigerant is in vaporizer side heat release）Hot water preparing.Hot water is divided into two branch roads, and one is that water supply branch road enters
Enter indoor end equipment, another enters surface cooler 14 and heat fresh air.Total backwater is then directly entered steaming by heat exchanger bypass valve
Send out device 2.Now need to open the regeneration by-pass line and surface cooler 14 and dehumidifying casing between regeneration casing and air-cooled condenser 4
Between dehumidifying by-pass line, air-cooled condenser 4（Now the refrigerant of low-temp low-pressure absorbs heat in condenser side）Cold air draft lead to
Cross regeneration by-pass line and be discharged into air, fresh air is then directly bypassed to surface cooler 14 by the by-pass line that dehumidifies, by surface cooler 14
It is heated to ventilation state point.
