Referring to fig. 2 and 3, on the premise that the air-conditioning operation mode is determined to be the winter operation mode, if the coil of the evaporator (i.e., the first heat exchanger) of the heat pump module of the air-conditioning system satisfies the frost suppression condition (before the frost removal condition is reached), the first thermal energy transfer pipeline 161 between the energy storage device 160 and the coil of the evaporator may be controlled to be conducted, so that the energy storage device 160 releases thermal energy to the coil of the first heat exchanger 151 through the first thermal energy transfer pipeline 161, so as to destroy and block the formation of a frost layer, thereby implementing uninterrupted heating of the heat pump module 150, achieving a better user experience effect, and improving the energy efficiency of the air-conditioning system.
Referring to fig. 1-6, the method further comprises: if a hot water preparation instruction or an auxiliary heating instruction is obtained, the second heat energy transfer pipeline 162 is controlled to be conducted, so that hot water can be prepared by using the heat energy stored in the energy storage device 160 or indoor heating can be performed, that is, the high-temperature oil smoke can transfer the waste heat to the hot water preparation device or the indoor heating device under the intervention of the energy storage device 160, so that the purpose of preparing hot water by using the waste heat of the oil smoke or heating indoors can be achieved, and a multipurpose energy utilization mode is achieved.
Referring to fig. 5, the step S206 may further include: if the air-conditioning operation mode is determined to be the winter operation mode, the heat pump module of the air-conditioning system is controlled to execute the heating mode, the second fresh air pipe section 112 can absorb heat released by the second heat exchanger 152 (condenser) of the heat pump module 150, so that fresh air preheated by the total heat exchanger 120 can be heated up again, and therefore, after the fresh air heated up twice enters the indoor environment, the temperature of the indoor environment can be raised, and the effect of heating the indoor environment is achieved, namely, the flue gas waste heat in the kitchen space can be transferred to the indoor environment to supply heat to the indoor environment; the first oil smoke pipe section 141 of the oil smoke pipeline is controlled to be communicated with the third oil smoke pipe section 143, high-temperature oil smoke discharged from the smoke outlet of the range hood 130 can flow to the third oil smoke pipe section 143 through the first oil smoke pipe section 141, enters the high-temperature oil smoke in the first oil smoke pipe section 141, can release part of heat to outdoor fresh air in the total heat exchanger 120, enters the high-temperature oil smoke in the third oil smoke pipe section 143, can exchange heat with the first heat exchanger 151 (evaporator) of the heat pump module 150, can improve the heat exchange efficiency of the first heat exchanger 151, and is beneficial to reducing the energy consumption of the heat pump module 150; the heat in the high-temperature oil smoke can be utilized at two positions of the total heat exchanger 120 and the first heat exchanger 151, so that two times of heat exchange of the high-temperature oil smoke is realized, and the energy utilization rate is improved; meanwhile, the first soot section 141 and the second soot section 142 of the soot duct are controlled to be cut off, so that the soot passing through the first soot section 141 can flow to the third soot section 143, and the soot utilization efficiency of the first heat exchanger 151 can be improved. When the heat pump module 150 performs the heating mode, the refrigerant flow direction therein is: compressor 153 → four-way valve 155 → second heat exchanger 152 → throttle valve 154 → first heat exchanger 151 → compressor 153. It should be noted that, in this embodiment, the high-temperature oil smoke firstly exchanges heat with the outdoor fresh air at the total heat exchanger 120, and then exchanges heat with the first heat exchanger 151 of the heat pump module 150 for the second time, which is beneficial to improving the heat energy utilization efficiency.
Referring to fig. 4, if the air-conditioning operation mode is determined to be the summer operation mode, the heat pump module of the air-conditioning system is controlled to execute the cooling mode, and the first soot section 141 and the third soot section 142 of the soot pipeline are controlled to be cut off, at this time, the high-temperature soot discharged from the exhaust port of the range hood 130 does not exchange heat with the first heat exchanger 151 (condenser) of the heat pump module 150 any more, so that the heat exchange efficiency of the first heat exchanger 151 is prevented from being reduced, and the energy consumption of the heat pump module 150 is prevented from being increased; meanwhile, the first oil smoke pipe section 141 of the oil smoke control pipeline is communicated with the second oil smoke pipe section 142, so that the oil smoke can be discharged to the outside through the first oil smoke pipe section 141 and the second oil smoke pipe section 142. When the heat pump module 150 performs the cooling mode, the flow direction of the refrigerant therein is: compressor 153 → four-way valve 155 → first heat exchanger 151 → throttle valve 154 → second heat exchanger 152 → compressor 153.
In addition, in the embodiment, the fresh air is heated/cooled, so that cold air/hot air is changed into warm air/cold air to heat/cool the indoor space, and when the kitchen space needs to be heated/cooled, the fresh air pipeline is communicated into the kitchen, so that the kitchen space can be heated/cooled by using the heated/cooled fresh air, and the comfort level in the kitchen can be improved; that is to say, need not to install heat pump module in the more kitchen space of oil smoke, so need not to consider the problem that particulate matters such as oil smoke adsorb on indoor heat exchanger, can guarantee the cleanness of heat exchanger, keep the good heat transfer of heat exchanger, be favorable to prolonging the life of air conditioner.
Referring to fig. 1 to 6, the fresh air duct may further include a fresh air inlet pipe segment 116, one end of the fresh air inlet pipe segment 116 is connected to the outside, the other end of the fresh air inlet pipe segment 116 is connected to one end of the first fresh air pipe segment 111 and one end of the third fresh air pipe segment 113 through the first three-way valve 114, and the other end of the first fresh air pipe segment 111 and the other end of the third fresh air pipe segment 113 are connected to one end of the second fresh air pipe segment 112 through the second three-way valve 115, so that the fresh air flow path of the fresh air duct may be adjusted by controlling the first three-way valve 114 and the second three-way valve 115.
Referring to fig. 4 to 6, the first soot section 141 may be connected to one end of the second soot section 142 and one end of the third soot section 143 by the third three-way valve 115, respectively, so that the soot flow path of the soot duct may be adjusted by controlling the third three-way valve 144.
Referring to fig. 1 to 3, a first control valve 163 may be installed on the first thermal energy transfer pipe 161, and the on/off of the first thermal energy transfer pipe 161 may be realized through the control and adjustment of the first control valve 163; referring to fig. 1 to 6, a second control valve 164 may be installed on the second thermal energy transfer pipe 162, and the second thermal energy transfer pipe 162 may be opened or closed by controlling and adjusting the second control valve 164.
