When using, this dehumidification air conditioner unit controls by microcomputer controller; The operation principle of this dehumidification air conditioner unit:
During single the refrigeration, on-off valve 7 is communicated with, and all the other on-off valves break off; Compressor 11 delivers to outdoor coil pipe used 13 to the gaseous state high-temperature high-pressure refrigerant through cross valve 19; Outdoor coil pipe used 13 this moments, high-temperature high-pressure refrigerant is the condensation heat release in outdoor coil pipe used 13 as condenser, can be through regulating its air quantity of rotating speed control of radiator fan 131 in Various Seasonal; The assurance system normally moves; Through expansion valve 18 throttling step-down inlet chamber inner coil pipes 12, air is cooled off in the evaporation of in evaporimeter 12, absorb heat of low-temp low-pressure liquid refrigerant from the liquid cold-producing medium of outdoor coil pipe used 13 HTHPs that come out; Be converted into the low-temp low-pressure gaseous refrigerant, accomplish kind of refrigeration cycle thereby gaseous refrigerant gets into compressor 11 again.
During heat pump heat supply, on-off valve 7 is communicated with, and all the other on-off valves break off; The high-temperature high-pressure refrigerant that compressor 11 is discharged flow to indoor coil 12 condensation heat releases through cross valve 19; The room air of heating, the liquid cold-producing medium of HTHP got into outdoor coil pipe used 13 heat absorption evaporations through expansion valve 18 throttling step-downs to indoor coil as condenser 12 this moments; Get into compressor 11 completion heat pump cycles as evaporimeter again thereby be converted into the low-temp low-pressure gaseous refrigerant outdoor coil pipe used 13 this moments.
When environment for use was in low temperature and high relative humidity, the dehumidification air conditioner unit carries out cooling dehumidification according to 11 pairs of room airs of the automatic compressor and starting of indoor humidity to be handled, and the temperature of exhaust after according to indoor cooling dehumidification of compressor 11 judged automatically and be communicated with on-off valve 8, on-off valve 9 or on-off valve 7 this moment; If the air themperature after the dehumidifying can satisfy indoor air-supply requirement; Then on-off valve 8 breaks off with on-off valve 9, and on-off valve 7 is communicated with, and the refrigeration system flow process is with single refrigeration; If the air themperature after the dehumidifying is lower than indoor air-supply requirement; Then on-off valve 7 breaks off, and on-off valve 8, on-off valve 9 are communicated with simultaneously, and the high temperature and high pressure gas that compressor 11 is discharged gets into condensation heat release in the first assistant heating coil pipe 20 and the second assistant heating coil pipe 21; The Cryogenic air of heating after indoor coil 12 dehumidifying; This moment, the first assistant heating coil pipe 20 and the second assistant heating coil pipe 21 were used as condenser, and the liquid cold-producing medium of HTHP separates out airborne condensate moisture through the indoor air of expansion valve 18 throttling step-down inlet chamber inner coil pipes, 12 heat absorption evaporative coolings; Reach the dehumidifying purpose, be converted into the low-temp low-pressure gaseous refrigerant and get into compressor 11 circulations again.If the temperature of dehumidifying back air is between above two kinds of situation; Then the connection of on-off valve 7 and on-off valve 8, on-off valve 9 or disconnection are decided by the humidity variation of microcomputer controller according to dehumidifying back air; Shunt a part of condensation heat and be used for indoor heating again, another part is still through outdoor coil pipe used 13 heat radiations, in Various Seasonal; Microcomputer controller can change its air quantity of rotating speed control of regulating radiator fan 131 automatically according to temperature and system pressure, and the assurance system normally moves.
Temperature is extremely low in indoor and outdoor; But indoor relative humidity is higher still need dehumidify the time, and the cooling and dehumidifying ability of dehumidification air conditioner unit itself has substantially exceeded actual required, and the dehumidification air conditioner unit need hang down load dehumidifying operation; On-off valve 10 connections this moment; Direct bypass part hot gas to indoor coil 12, this flow process reduces the cooling and dehumidifying ability of indoor coil 12 on the one hand, also guarantees the reliability of system in low load running simultaneously.On-off valve 7 is still regulated automatically according to the air themperature after dehumidifying by microcomputer controller when dehumidifying with on-off valve 8, on-off valve 9 and is communicated with or disconnection, guarantees the indoor requirement that heat meets the air heat amount that adds again.
The dehumidification air conditioner unit is designed to coil pipe 121 and lower coil pipe 122 with indoor coil 12; Between last coil pipe 121 and lower coil pipe 122, increased a secondary return air motorized adjustment air-valve 123; Secondary return air motorized adjustment air-valve 123 can change according to indoor temperature and humidity regulates open degree automatically by microcomputer controller; Change the secondary return air amount, thereby change the secondary return air mixing ratio, make ventilation state follow the tracks of indoor load and change and change.
The beneficial effect of this dehumidification air conditioner unit is: this dehumidification air conditioner unit integrates Cooling and Heat Source and air-treatment, the dehumidification air conditioner unit that the cost low power consuming is little.Secondary return air motorized adjustment air-valve can change according to indoor temperature and humidity regulates open degree, changes the secondary return air amount, thereby changes the secondary return air mixing ratio, makes ventilation state follow the tracks of indoor load and changes and change.Can guarantee that system normally moves through its air quantity of rotating speed control of regulating radiator fan in Various Seasonal.Have assistant heating branch road and bypass branch road and indoor assistant heating coil pipe is arranged side by side, satisfy dehumidifying requirement under the annual variable working condition, guarantee the operation normally and efficiently of source pump simultaneously.On-off valve is the bi-bit bi-pass solenoid directional control valve, and the general part cost is low.
It is apparent to one skilled in the art that the utility model can be changed into multiple mode, and the scope that breaks away from the utility model is not thought in such change.The conspicuous modification of the technical staff to said field that all are such is within the scope that is included in this claim.
