Operation principle of the present invention:
(1) refrigeration+new wind+purification:
The high-temperature high-pressure refrigerant gas that compressor 1 exhaust outlet is discharged enters the first cross valve 2, second cross valve 3, second cross valve 3 no power, cold-producing medium cannot be passed through by this road, the refrigerant gas entering the first cross valve 2 is cooled to high-temperature high-pressure refrigerant liquid by axial flow blower 4 through outdoor air by outdoor finned heat exchanger 5, again through the first check valve 6, enter the 3rd check valve 12, two-way reservoir 11, because the 3rd check valve 12 is reverse, cold-producing medium cannot enter heat(ing) coil 13, flow through the cold-producing medium of two-way reservoir 11 through second choke 10 throttling, the cold-producing medium two-phase fluid becoming low-temp low-pressure enters the refrigerant gas that the heat absorption of indoor finned heat exchanger 14 flashes to low-temp low-pressure, enter compressor 1 air entry via the first cross valve 2 to be again compressed into high-temperature high-pressure refrigerant gas and to be discharged by compressor 1 exhaust outlet, so move in circles, reach refrigeration object, as remaining in there being cold-producing medium in heat(ing) coil 13, then enter compressor 1 air entry by the second cross valve 3, thus ensure that the reliable and stable operation of refrigeration,
The room air entered by return air inlet 19 purifies Hou Fen bis-tunnel through return air screen pack 15:
Lead up to air heat exchanger 17, with purified by new wind screen pack 16 after enter the outdoor high temperature of air heat exchanger 17 fresh air carry out damp and hot exchange or Exchange of apparent heat after, heat up rise wet or after heating up by exhaust fan 18 discharged to outdoor; High temperature fresh air after outdoor purification carries out damp and hot exchange or Exchange of apparent heat at air heat exchanger 17, reducing temperature and humidity or cooling, thus achieves the cold recovery of air draft;
Another Lu Zeyu reducing temperature and humidity or the rear fresh air mixing of cooling, after indoor finned heat exchanger 14 heat release cooling wet down, in heat(ing) coil 13(is due to heat(ing) coil, cold-producing medium is not had to pass through again, therefore without heat exchange), send into indoor through air supply motor 8, reach the object of refrigeration+new wind+purification.
(2)+new wind+purification is heated:
The high-temperature high-pressure refrigerant gas that compressor 1 exhaust outlet is discharged is through the first cross valve 2, second cross valve 3, second cross valve 3 no power, cold-producing medium cannot be passed through by this road, the refrigerant gas entering the first cross valve 2 through the heat release of indoor finned heat exchanger 14 in room air, be cooled to high-temperature high-pressure refrigerant liquid, again through the second check valve 9, two-way reservoir 11, because the 3rd check valve 12 is reverse, cold-producing medium cannot heat(ing) coil 13, first throttle device 7 throttling can only be entered, the cold-producing medium two-phase fluid becoming low-temp low-pressure enters the refrigerant gas that the heat absorption of outdoor finned heat exchanger 5 flashes to low-temp low-pressure, axial flow blower 3 by cold discharged to outdoor, refrigerant gas is entered compressor 1 air entry via the first cross valve 2 again and is compressed into high-temperature high-pressure refrigerant gas and is discharged by compressor 1 exhaust outlet, so move in circles, reach and heat object, as remaining in there being cold-producing medium in heat(ing) coil 13, then enter compressor 1 air entry by the second cross valve 3, thus ensure that the reliable and stable operation heated,
The room air entered by return air inlet 19 purifies Hou Fen bis-tunnel through return air screen pack 15:
Lead up to air heat exchanger 17, with purified by new wind screen pack 16 after enter the outdoor low temperature of air heat exchanger 17 fresh air carry out damp and hot exchange or Exchange of apparent heat after, after reducing temperature and humidity or cooling by exhaust fan 18 discharged to outdoor; Low temperature fresh air after outdoor purification carries out damp and hot exchange or Exchange of apparent heat at air heat exchanger 17, heats up and rises wet or heat up, thus achieve air-to-air energy recovery;
Fresh air mixing after another Lu Zeyu heats up and wets or heat up, after indoor finned heat exchanger 14 heat absorption heating, in heat(ing) coil 13(is due to heat(ing) coil, cold-producing medium is not had to pass through again, therefore without heat exchange), indoor are sent into by air supply motor 18, send into indoor through air supply motor 8, reach and heat+the object of new wind+purification.
(3) dehumidify+new wind+purification:
The high-temperature high-pressure refrigerant gas that compressor 1 exhaust outlet is discharged divides two tunnels:
Main road enters the first cross valve 2, is cooled to high-temperature high-pressure refrigerant liquid by axial flow blower 4 through outdoor air by outdoor finned heat exchanger 5, then through the first check valve 6;
Bypass enters the second cross valve 3, second cross valve 3 is energized, cold-producing medium enters heat absorption in heat(ing) coil 13 and is cooled to high-temperature high-pressure refrigerant liquid, again through the 3rd check valve 12, through the first check valve 6 main road refrigerant liquid with after the bypass refrigerant liquid of the 3rd check valve 12 converges, enter two-way reservoir 11, through second choke 10 throttling, the cold-producing medium two-phase fluid becoming low-temp low-pressure enters the refrigerant gas that the heat absorption of indoor finned heat exchanger 14 flashes to low-temp low-pressure, enter compressor 1 air entry via the first cross valve 2 to be again compressed into high-temperature high-pressure refrigerant gas and to be discharged by compressor 1 exhaust outlet, so move in circles, reach the object of dehumidifying,
The room air entered by return air inlet 19 purifies Hou Fen bis-tunnel through return air screen pack 15:
Lead up to air heat exchanger 17, with purified by new wind screen pack 16 after enter the outdoor high temperature of air heat exchanger 17 fresh air carry out damp and hot exchange or Exchange of apparent heat after, heat up rise wet or after heating up by exhaust fan 18 discharged to outdoor.High temperature fresh air after outdoor purification carries out damp and hot exchange or Exchange of apparent heat at air heat exchanger 12, reducing temperature and humidity or cooling, thus achieves the cold recovery of air draft;
Another Lu Zeyu reducing temperature and humidity or the rear fresh air mixing of cooling, after indoor finned heat exchanger 14 reducing temperature and humidity, then heat through heat(ing) coil 13, send into indoor by air supply motor 8, reach the object of dehumidifying+new wind+purification.
(4) new wind+purification:
During new wind pattern, source pump does not work, air supply motor 8 low cruise, and exhaust fan 18 normally runs;
The room air entered by return air inlet 19 purifies Hou Fen bis-tunnel through return air screen pack 15:
Lead up to air heat exchanger 17, with purified by new wind screen pack 16 after enter air heat exchanger 17 outdoor fresh air carry out damp and hot exchange or Exchange of apparent heat after, after heat exchange by exhaust fan 18 discharged to outdoor; Fresh air after outdoor purification has carried out heat exchange at air heat exchanger 17, thus achieves air draft (cold) recuperation of heat;
Another Lu Zeyu is fresh air mixing after air heat exchanger 17 heat exchange, is not worked, do not have heat exchange by indoor finned heat exchanger 14, heat(ing) coil 13(due to source pump) after, send into indoor through air supply motor 8, reach the object of new wind+purification.
