Detailed description of the invention
As shown in Figure 1, the present invention includes three parts, Part I is compressor 7, electric three-way regulating valves 12, main condenser 13, condensation heat-recovery condenser 8, the check valve a7 of composition air-cooled air conditioner unit, check valve b14, reservoir 5, heating power expansion valve 3, evaporimeter 4; Part II is the air passage of heat 1 again, arranges successively screen pack 2, evaporimeter 4, condensation heat-recovery condenser 8, wind pushing temperature sensor 9, breeze fan 10 in this passage; Part III is the air-cooled heat exchanger channels 15 of main condenser, arranges successively main condenser 13, exhaust fan 11 in this passage.It is characterized in that in air-cooled air conditioner unit, compressor 7 exhaust outlets connect electric three-way regulating valves 12, electric three-way regulating valves 12 connects main condenser 13 and condensation heat-recovery condenser 8, main condenser 13 connects check valve a6, condensation heat-recovery condenser 8 connects check valve b14, check valve a6 is connected reservoir 5 with check valve b14 simultaneously, reservoir 5 connects heating power expansion valve 3, and heating power expansion valve 3 connects evaporimeter 4, and evaporimeter 4 connects compressor 7 air entries and forms a closed circuit; Air again in the passage of heat 1 new wind mix with return air after through evaporimeter 4 cool-down dehumidifications, then after heat, send into air-conditioned room again through condensation heat-recovery condenser 8; In the air-cooled heat exchanger channels 15 of main condenser, new wind and main condenser 13 carry out cold and hot exchange afterwards directly discharged to atmosphere.
1) compressor 7 is discharged high-temperature high-pressure refrigerant gas and is entered main condenser 13 and condensation heat-recovery condenser 8 through electric three-way regulating valves 12, cold-producing medium is pooled to reservoir 5 through check valve a7 and check valve b14 respectively carry out exchange heat with air in main condenser 13 and condensation heat-recovery condenser 8 after, and then enter evaporimeter 4 air carried out becoming after wet down cooling processing the refrigerant gas of low-pressure low-temperature through heating power expansion valve 3 reducing pressure by regulating flows, finally sucked compression by compressor 7, complete a kind of refrigeration cycle.
2) air is again in the passage of heat 1, first indoor return air mix with the new wind in the external world, mixed air is processed apparatus dew point by evaporimeter 4 cool-down dehumidifications of air-cooled air conditioner unit after filter screen 2 filters, and then through condensation heat-recovery condenser 8, air is carried out sending into air-conditioned room after heat again.
3) when the wind pushing temperature recording when wind pushing temperature sensor 9 is less than the wind pushing temperature setting value of system, electric three-way regulating valves 12 is started working, the refrigerant flow that flows to condensation heat-recovery condenser 8 strengthens, and the thermal discharge of condensation heat-recovery condenser 8 increases, and wind pushing temperature raises; On the contrary, when the wind pushing temperature recording when wind pushing temperature sensor 9 is greater than the wind pushing temperature setting value of system, electric three-way regulating valves 12 is also started working, and the refrigerant flow that flows to condensation heat-recovery condenser 8 reduces, the thermal discharge of condensation heat-recovery condenser 8 reduces, and wind pushing temperature reduces; In the time that wind pushing temperature is apparatus dew point, the electric three-way regulating valves 12 that leads to condensation heat-recovery condenser 8 is closed.
