The utility model belongs to air conditioner dehumidification cooling heat supply field relates to the energy waste who exists when overcoming civil buildings and utilizing new trend cooling heat supply, in particular to ventilation air conditioning system of indoor oil smoke exhaust and new trend dehumidification cooling, heat supply.
In summer, the indoor high temperature oil smoke 34 generated by cooking is collected to the oil smoke exhaust inlet pipe 2 through the exhaust port 1 by the pressure of the exhaust ventilator 3. Further, the exhaust fumes pass through the fume purifier 11. Next, through the heat exchange box 4 arranged on the roof 32, the heat insulation layer 12 and the phase change material 13 are respectively arranged at the contact position of the heat exchange box 4 and the outside, and the heat exchange coil 14 is arranged inside. Thus, the heat of the cooking fumes is transferred to the heat transfer medium inside the heat exchange coil 14. In addition, since the temperature of the cooking fume is higher than the phase transition temperature of the phase change material 13 selected for use, the phase change material 13 also absorbs a part of the heat of the cooking fume. The heat-insulating layer 12 can effectively prevent heat in the heat exchange box 4 from being transferred to outdoor air. The heat-exchanged oil fume 35 becomes low temperature and enters the outdoor atmosphere through the oil fume outlet pipe 5. The outdoor damp and hot fresh air 33 enters the fresh air processing box 7 arranged below the heat exchange box 4 through the fresh air pipe 6 under the pressure action of the fresh air fan 8. The moist hot fresh air is first passed through a fresh air purification section 17 to remove contaminants. Then, the fresh air dehumidifying section 18 is provided, and the support 21, the moisture absorption component 20, the reheating coil 19, the moisture absorption component 20 and the support 21 are sequentially arranged in the fresh air dehumidifying section 18. The water vapor in the fresh air is absorbed by the solid moisture absorption material of the moisture absorption component 20 and becomes dry and hot fresh air. Second, the fresh air passes through the condenser section 22 and then to the temperature control section 28 (which now functions as a cooling element). The low temperature medium (water or other medium) provided by the cold and heat source 25 cools the fresh air in the temperature adjusting section 28 through the water supply pipe 26 and then returns from the water return pipe 27. At this time, the outdoor fresh air changes from moist heat to dry low temperature, passes through the humidity sensor 29 and the temperature sensor 30, and is sent into the room from the air outlet 10 through the air supply pipe 9. When the temperature of the fresh air in the blast pipe 9 is different from the temperature set by the temperature sensor 30, the cold and heat source 25 can interlockingly adjust the flow rate to control the temperature of the fresh air. When the humidity of the fresh air in the air supply pipe 9 is higher than the set value of the humidity sensor 29, the moisture absorption component 20 is saturated. At this time, the circulation pump 16 and the control valve 15 are interlocked to be opened, the control valve 15 is an expansion valve, and the heat medium in the heat exchange coil 14 flows to the reheat coil 19 to heat the moisture absorbing unit 20. The heated heat transfer medium temperature is lowered back to heat exchange coil 14. And because the phase change temperature of the selected phase change material 13 is the same as the regeneration temperature of the moisture absorption component 20, the phase change material 13 starts to solidify and release heat to the air in the heat exchange box 4, and further the heat is transferred to the heat transfer medium of the heat exchange coil 14. Therefore, the heat in the heat exchange box 4 is transferred to the reheating coil 19 through the heat transfer medium to carry out the regeneration process of the moisture absorption assembly 20. When the heat of the exhaust fumes absorbed by the heat exchange box 4 does not satisfy the heat required for regeneration, the electric heater 31 may be turned on. When the high-temperature water vapor generated in the regeneration process passes through the condensation section 22, the dew point temperature of the high-temperature water vapor is higher than the surface temperature of the aluminum plate arranged on the condensation section 22, and the water vapor is condensed into water drops and finally flows into the water collection tank 23 arranged below the condensation section 22. The lower part of the water collecting tank 23 is provided with a drainage opening 24. When the water level of the water collecting tank 23 is too high, the drain opening 24 is opened. Wherein, the aluminum plate is arranged in a folded shape to increase a contact area with the water vapor, thereby improving condensation efficiency.
See fig. 5. In winter, the fresh air is dried outdoors, and no dehumidification is needed, so the moisture absorption component 20 and the condensation section 22 can be taken away from the fresh air treatment tank 7. The indoor oil fume exhaust treatment process is the same as the process in summer, and is not repeated. The outdoor cold fresh air 36 firstly passes through the fresh air purification section 17 and then enters the fresh air dehumidification section 18, and at the moment, the circulating pump 16 and the control valve 15 are started. The heat transfer medium in the heat exchange coil 14 transfers the heat absorbed by the phase change material 13 in the heat exchange box 4 to the fresh air dehumidifying section 18 under the action of the circulating pump 16, so as to preheat the cold fresh air. The temperature of the preheated fresh air can not meet the requirement of the temperature of the supplied air generally, when the fresh air passes through the temperature adjusting section 28 (which plays a heating role at this time), the cold and heat source 25 can provide a high-temperature medium (water or other media) to heat the fresh air through the water supply pipe 26, and the flow of the high-temperature medium can be adjusted in an interlocking manner according to the temperature sensor 30, so that the temperature of the fresh air is controlled within a set range. The heated fresh air enters the room through the blast pipe 9. The high temperature medium (water or other medium) provided by the cold and heat source 25 heats the fresh air in the temperature adjusting section 28 through the water supply pipe 26 and then returns from the water return pipe 27.
See fig. 1-5. When the system is in transition seasons, the humidity and the temperature of outdoor fresh air generally meet requirements, the system can operate in full fresh air, and energy consumption is reduced.

In summer, a large amount of high-temperature oil smoke is generated when a user cooks in a kitchen, the high-temperature oil smoke is sent to the heat exchange box 4 by the range hood, heat in the high-temperature oil smoke is absorbed by the heat transfer medium and the phase-change heat storage material in the heat exchange coil 14 respectively, and then the high-temperature oil smoke is changed into low-temperature gas to be discharged out of the outdoor atmosphere, so that the emission of the high-temperature gas is reduced, and the environment protection is facilitated. In addition, the heat-insulating material is arranged at the place where the heat exchange box 4 is in contact with the outdoor space, so that the heat absorbed by the phase change material 13 can be effectively prevented from being transferred to the outdoor space. The outdoor moist and hot fresh air firstly passes through the fresh air purification section 17 to remove the particle pollutants in the fresh air. Secondly, the water vapor passes through the fresh air dehumidifying section 18, and is absorbed by the moisture absorbing component 20 to become dry hot air. Finally, the air passes through the temperature adjusting section 28 (cooling section in summer) and is changed into dry low-temperature air, and then the dry low-temperature air is conveyed to the indoor by the blower, so that the purposes of temperature reduction and dehumidification are achieved. When the moisture absorption assembly 20 is saturated, the moisture is desorbed by heating, so that the regeneration is realized, and the moisture absorption is repeated. The heat required for the regeneration process of the absorbent assembly 20 may be provided by the phase change material 13, and the capacity and the phase change temperature of the phase change material 13 may be selected according to the regeneration temperature and the heat of the absorbent assembly 20. Because the utility model discloses store the heat in the oil extraction cigarette in phase change material 13, consequently, no matter cook or do not cook, phase change material 13 homoenergetic provides the required heat that moisture absorption component 20 regenerates. If the heat in the phase change material 13 is not sufficient, a portion of the heat may be provided by the electric heater 31, determining the stability of the system.

The aluminum plate is provided with the saw-toothed structure, so that the contact area is greatly increased, and the condensation effect is improved. Furthermore, this way of condensation does not consume energy.
In winter, no dehumidification is required due to the low relative humidity of the outdoor fresh air. Therefore, in winter, the moisture absorbing component 20 and the condensation section 22 in the fresh air dehumidifying section 18 can be taken away. The heat in the range hood is absorbed by the phase change material 13, similar to summer conditions. Outdoor fresh air firstly passes through the fresh air purification section 17 and then passes through the fresh air dehumidification section 18, and at the moment, the fresh air dehumidification section 18 only has the reheating coil pipe 19 to preheat the dry and cold fresh air. Finally, the preheated fresh air passes through the temperature adjusting section 28 (heating section in winter), is changed into hot air with set temperature, and is sent into the room by the air feeder, so that the heating effect is achieved.
During the transition season, whether dehumidification and heating are needed or not can be judged according to the temperature and the humidity of outdoor fresh air. The fresh air in the common transition season does not need to be processed, and can be sent into the room in a full fresh air mode.
