With reference to shown in Figure 1, according to an embodiment of the invention, electrochemistry air-conditioning system includes electrochemistry hydrogen pump 1, first Metal hydride heat exchanger 2, the second metal hydride heat exchanger 3, the first blower fan 4 and the second blower fan 5, the first metal hydride change Hot device 2 is connected to the first electrode of electrochemistry hydrogen pump 1, and the second metal hydride heat exchanger 3 is connected to the second of electrochemistry hydrogen pump 1 Electrode, electrochemistry air-conditioning system also include the second air port in the first air port and communication chamber outside communication chamber, the first metal hydride Thing heat exchanger 2 is arranged between air inlet and the first air port of the first blower fan 4, and the second metal hydride heat exchanger 3 is arranged on Between the air inlet of two blower fans 5 and the second air port；The air outlet of first blower fan 4 and the second blower fan 5 is selectively communicated to room It is interior and outdoor.
, can be by controlling the rotation direction of electrochemistry hydrogen pump 1 to realize the first gold medal when the electrochemistry air-conditioning system works Belong to the continuous suction hydrogen of hydride heat exchanger 2 and the second metal hydride heat exchanger 3 and put hydrogen, while by reasonably arranging blower fan With the connected relation in air channel so that electrochemistry air-conditioning system can change the first metal hydride heat exchanger 2 and the second metal The suction hydrogen of hydride heat exchanger 3 completes heat by changing air channel flow direction with when putting hydrogen state with metal hydride heat exchanger The air of exchange can be correctly delivered to target location so that even if the switchover operation state of electrochemistry hydrogen pump 1, electrochemistry is empty Adjusting system is maintained to continuous refrigeration or heating operation, realizes simple in construction, and cost is relatively low, and use can be effectively ensured The usage comfort at family, and energy-conserving and environment-protective, noise are relatively low.
The air outlet of first blower fan 4 is connected by the first air channel 6 with indoor, and the air outlet of the first blower fan 4 passes through the second wind Road 7 is connected with outdoor, and the air outlet of the second blower fan 5 is connected by the 3rd air channel 8 with indoor, and the air outlet of the second blower fan 5 passes through 4th air channel 9 connects with outdoor, and electrochemistry air-conditioning system also includes control valve group, and control valve group controls the air-out of the first blower fan 4 Mouthful and the air outlet of the second blower fan 5 connected state, during so that the air outlet of the first blower fan 4 is with indoor connecting, the second blower fan 5 Air outlet connects with outdoor, and when the air outlet of the first blower fan 4 is with outdoor connect, the air outlet of the second blower fan 5 connects with indoor.
By adjusting the air-out path of the first blower fan 4 and the second blower fan 5, can cause when room air passes through the first metal When being transported to interior after the heat exchange of hydride heat exchanger 2, outdoor air is after the heat exchange of the second metal hydride heat exchanger 3 It is transported to outdoor；When outdoor air is transported to interior after the heat exchange of the second metal hydride heat exchanger 3, Interior Space Gas is transported to interior after the heat exchange of the first metal hydride heat exchanger 2, so as to carry out the commutation of electrochemistry hydrogen pump 1 When, even if the suction heat release state of the first metal hydride heat exchanger 2 and the second metal hydride heat exchanger 3 is changed, The overall heat exchange environment of interior is not interfered with, ensures that user has preferable usage comfort.
Preferably, control valve group includes being arranged between the air outlet in the first air channel 6, the second air channel 7 and the first blower fan 4 First triple valve 10, and the second triple valve being arranged between the air outlet of the 3rd air channel 8, the 4th air channel 9 and the second blower fan 5 11。
When electrochemistry air-conditioning system is in refrigerating state, and electrochemistry hydrogen pump applies malleation, now the first triple valve 10 The connection of AB mouths, AC mouths disconnect, and the AC mouths of the second triple valve 11 connection, AB mouths disconnect, and the first metal hydride heat exchanger 2 puts hydrogen Heat absorption, is used as evaporator, and the second metal hydride heat exchanger 3 inhales hydrogen heat release, is used as condenser, and part is indoor Enter after the first air port of the air through electrochemistry air-conditioning system in air-conditioning system, carried out with the first metal hydride heat exchanger 2 After heat exchange cooling, the air inlet of the first blower fan 4 is inhaled into the presence of the first blower fan 4, is entered after the first triple valve 10 In first air channel 6, then flowed out through the first air channel 6 from indoor connected entrance, to indoor carry out refrigeration cool-down.Meanwhile outdoor air Enter after the second air port through electrochemistry air-conditioning system in air-conditioning system, exchanged heat with the second metal hydride heat exchanger 3, After the heat for absorbing the release of the second metal hydride heat exchanger 3, the second blower fan 5 is inhaled into the presence of the second blower fan 5 Air inlet, enter in the 4th air channel 9 after the second triple valve 11, then discharged through the 4th air channel 9 from outdoor connected entrance, so as to Heat after heat exchange is discharged indoor.
When electrochemistry hydrogen pump applies negative pressure, now the AB mouths of the first triple valve 10 disconnect logical, the connection of AC mouths, the second threeway The AC mouths of valve 11 disconnect, and AB mouths connection, the second metal hydride heat exchanger 3 puts hydrogen heat absorption, is used as evaporator, the first gold medal Belong to hydride heat exchanger 2 and inhale hydrogen heat release, used as condenser.First wind of the part room air through electrochemistry air-conditioning system Enter after mouthful in air-conditioning system, after carrying out heat absorption heating with the first metal hydride heat exchanger 2, in the effect of the first blower fan 4 Under be inhaled into the air inlet of the first blower fan 4, entered after the first triple valve 10 in second air channel 7, then through the second air channel 7 from Outdoor connected entrance discharge is indoor, so as to which the heat release of the first metal hydride heat exchanger 2 is discharged into outdoor.Meanwhile outdoor air Enter after the second air port through electrochemistry air-conditioning system in air-conditioning system, exchanged heat with the second metal hydride heat exchanger 3, After the absorbing and cooling temperature of the second metal hydride heat exchanger 3, the air intake of the second blower fan 5 is inhaled into the presence of the second blower fan 5 Mouthful, entered after the second triple valve 11 in the 3rd air channel 8, be then emitted into interior from indoor connected entrance through the 3rd air channel 8, from And continue to indoor carry out cooling refrigeration.
Continuously electrochemistry hydrogen pump is commutated by above-mentioned mode, can be always ensured that electrochemistry air-conditioning system is discharged What it is to interior is cold air, be emitted into outdoor for hot-air, without by the first metal hydride heat exchanger 2 and the second metal The structure limitation of hydride heat exchanger 3, therefore the continuous cooling of air-conditioning can be conveniently realized.Due to this electrochemistry air-conditioning system Only by the state of adjustment triple valve and the traffic direction of electrochemistry hydrogen pump, it is possible to conveniently realize electrochemistry air-conditioning system Continuous cooling and heating, therefore without carrying out larger adjustment and conversion to the structure of electrochemistry air-conditioning system, in electrochemistry The loss of heat and cold is smaller caused by during air-conditioning system State Transferring, and simple in construction, and cost is relatively low, is easy to Realize.
The heating situation of this air-conditioning system is similar with refrigeration situation, and I will not elaborate.
