The building energy conversion and ventilating device A' composed of the above components, that is, when the indoor temperature value TA is greater than the cold air supply set value TA1, the cold air is supplied in the cold air circulation (as shown in the third figure), and the indoor air is at this time. The air is discharged from the exhaust duct 50, and the indoor air is filtered through the exhaust filter 502 of the air outlet 501, and then flows through the air pre-cooling heat exchanger 811 for heat exchange. The air pre-cooling heat exchanger 811 generates air. The energy conversion of the cold action is such that the air discharged from the room obtains the first cooling effect, and the circulating water in the air pre-cooling heat exchanger 811 flows out from the water outlet end 811a of the air pre-cooling heat exchanger 811, and then The water jet head L411 is sprayed on the first water evaporator 812. The filtering and evaporating action of the first water evaporator 812 generates an evaporation heat absorption effect with the passing air to transfer the sensible heat in the air. The air passing through the water evaporator 812 obtains the second cooling, and the circulating water sent by the first water evaporator 812 is also cooled, and then the air is pre-cooled by the first water pump 813. The 811 is circulated, and the air passing through the first water evaporator 812 is subjected to heat exchange at the outdoor side water heat exchanger 822 flowing through the second water circulation heat exchanger group 82, and the air obtains indoor side water heat exchange. The heat of the device 821, but the moisture obtained by the first water evaporator 812, can be converted into wet heat during the heat exchange process of the second heat exchanger 73, so the outdoor side water heat exchanger 822 can remove the heat transmitted from the indoor side water heat exchanger 821, and the temperature of the air discharged outside the room is far lower than the temperature of the air directly discharged from the outdoor air by the condensation gas, thereby reducing the waste heat discharge. In addition, the circulating water sent from the first water evaporator 812 is transferred to the air pre-cooling heat exchanger 811 by the first water pump 813, and the circulating water of the outdoor side water heat exchanger 822 When leaving the outdoor side water heat exchanger 822, the water temperature flowing out of the water outlet end 822a is close to the dew point temperature of the indoor side air, so the air entering from the air inlet duct 60 passes through the air inlet 601 first. Air inlet filter 602 After filtering, it flows through the indoor side water heat exchanger 821, and the intake air is pre-cooled and cooled first because the circulating water has approached the dew point temperature of the indoor side air, and when the intake air passes through the first heat exchanger 72, The heat load of the heat source unit 7 has been reduced, so that the operation efficiency can be enhanced, and the air conditioning energy can be adjusted according to the environmental requirements of the building, and the low temperature and fresh air required in the room can be supplied, and the purpose of energy saving can be achieved.

When the indoor temperature value TA is greater than the cold air supply set value TA1, the cold air is supplied with the cold air, and the refrigerant of the heat source unit 3 flows from the heat source device 71 to the first refrigerant tube L31, and then enters the second heat exchanger 73. After the second heat exchanger 73 exchanges heat with the exhaust gas for condensation heat removal, then flows through a second refrigerant tube L32, and then reaches the first heat exchanger 72 to perform heat exchange for evaporation and heat absorption of the intake air. The intake air temperature can be adjusted according to the demand of the room to supply the cold air required in the room, and the refrigerant flowing out from the first heat exchanger 72 flows back to the heat source device 71 through a third refrigerant connecting pipe L33. To complete a cold air cycle.

When the indoor temperature value TA is in the intermediate temperature range between the heating supply set value TA2 and the cold air supply set value TA1, the controller C2 controls the second water pump 823 to operate to recover the heat cycle, and the operation of the second water pump 823 is utilized. The ventilation cycle operation performed by the second water circulation heat exchanger group 82 is started. As shown in the seventh figure, when the indoor temperature value TA is too high, that is, TA is greater than the first set temperature value TA1', the controller C2 starts the first The water pump 813 is operated to evaporate and refrigerate water to improve its cooling capacity; and when the indoor temperature value TA is lower than the second set temperature value TA2', the controller C2 controls the first water pump 813 to stop running; When the value TA is lower than the heating supply set temperature value TA2, the heating is started to be supplied to the heating cycle (as shown in the fourth figure). When the indoor air is discharged from the exhaust duct 50, the indoor air first passes through the exhaust vent of the exhaust 501. After filtering the net 502, when the air pre-cooling heat exchanger 811 and the first water evaporator 812 pass through, the first water pump 813 of the first water circulation heat exchanger group 81 is stopped by the control of the controller C2, so air The circulating water in the pre-cooling heat exchanger 811 and the first water evaporator 812 is not circulated, so the air is not pre-cooled and evaporated, so no energy conversion occurs, and the air passes through the outdoor side water heat exchanger 822 and the second heat exchange. The device 73 performs heat exchange (the second heat exchanger 73 is used as an evaporator); in addition, the air entering from the inlet duct 60 is filtered through the air inlet filter 602 of the air inlet 601, and then filtered. After the water vaporization and humidification effect of the second water evaporator 831 of the third water circulation heat exchanger group 83 passes through the indoor side water heat exchanger 821, the indoor side water heat exchanger 821 receives the outdoor side water heat exchanger 822 for recovery. The heat of the air is exhausted indoors, so when the intake air passes through the first heat exchanger 72 (when the first heat exchanger 72 is a condenser function), the intake air is preheated and the heat load of the heat source unit 7 is increased. Has been reduced, can enhance its operating efficiency, and adjust the air conditioning energy according to the environmental needs of the building, supply the high temperature and fresh air required indoors, to achieve the purpose of energy saving; as for the heating cycle, the refrigerant of the air conditioning unit 7 From the heat source device 71 The flow passes through the third refrigerant tube L33, and then enters the first heat exchanger 72, and the heat exchange between the first heat exchanger 72 and the intake air is performed, and the intake air temperature can be adjusted according to the indoor demand. To supply the heating required in the room, then the refrigerant flowing out of the first heat exchanger 72 passes through the second refrigerant tube L32, and then reaches the second heat exchanger 73 to exchange heat of evaporation and heat absorption of the exhaust gas. Although the air temperature has been exhausted to the indoor side water heat exchanger 821 for heat supply in the outdoor side water heat exchanger 822, the temperature is higher than the outdoor temperature, so that the evaporation heat absorption efficiency of the second heat exchanger 73 can be enhanced; The refrigerant flowing out of the second heat exchanger 73 is returned to the heat source device 71 via the first refrigerant pipe L31 to complete a heating cycle.

When the heat source unit in the second embodiment is a central ice/hot water heat source unit (refer to FIGS. 5 and 6), the heat source unit 7' is controlled by the controller C2, and the heat source unit 7' The utility model comprises: a heat source device 71', which is a power source for the refrigerant transmission of the heat source unit 7', and supplies a heat source (the heat source comprises cold energy and heat energy, the cold energy is ice water, and the heat energy is hot water a first heat exchanger 72' is disposed in the air inlet 60 to absorb heat through the intake air (as shown in the fifth figure, during the cold air circulation, the first heat exchanger 72' is Heat exchange of an ice water coil) or heat release (the first heat exchanger 72' is a function of a hot water coil during a heating cycle as shown in FIG. 6), the first heat exchanger 72 'The first inlet and outlet end 721' is connected to the heat source device 71' by a second output pipe L63, and receives input of a heat source (which is cold energy during cold air circulation and heat energy during heating cycle), The second inlet and outlet end 722' of the first heat exchanger 72' is connected to the heat source device 71' by a second return pipe L64; A second heat exchanger 73' is disposed in the exhaust duct 50 to radiate heat through the exhaust gas (as shown in FIG. 5, the second heat exchanger 73' is heated during the cold air circulation. The function of the water coil) or the heat absorption (as shown in the sixth figure, during the heating cycle, the second heat exchanger 73' is a function of an ice water coil), the second heat exchanger 73' The first inlet and outlet end 731' is connected to the heat source device 71' by a first output pipe L61, and receives a heat source (the heat source is heat energy discharged by the heat source unit during cold air circulation, and is cold energy during heating cycle) The input, the second inlet and outlet end 732' of the second heat exchanger 73' is connected to the heat source device 71' by a first return pipe L62.

In summary, the invention has the effects of air conditioning cold, heating and fresh air supply, so that the air inlet after heat exchange can be closer to the dew point temperature of the indoor side air, and the air conditioner can be adjusted according to the environmental demand of the building throughout the year. Energy operation, that is, the invention is characterized in that after the indoor and outdoor energy is automatically balanced, the required heat energy or heat energy is supplemented by the heat source unit according to actual demand; therefore, the best energy in the building can be obtained with the lowest energy consumption.
