The air inlet of the air inlet duct 10 and the air outlet of the exhaust duct 20 are respectively provided with an air duct 50 and an air duct 60. Taking the air duct 61 as an example, the exhaust duct 20 is provided with a connecting portion 61 to be assembled at one end of the air duct 60. The other end of the air duct 60 is connected to a wall 200 to connect the indoor space to the outdoors, thereby introducing external air into the indoor space for circulation. Therefore, the portable all-outdoor energy conversion device can be easily installed. The air inlet of the air inlet duct 10 and the air outlet of the exhaust duct 20 are respectively provided with filters 11 and 21 for filtering odors and harmful gases in the air. In addition, the fans 12 of the air inlet duct 10 and the exhaust duct 20 ,22 Direct airflow toward indoor or outdoor spaces.

The hydrothermal circulation heat exchange unit is a circulation pipeline composed of a pre-cooled water heat exchanger 41, a water evaporator 42, a first water heat exchanger 44, and a second water heat exchanger 45 connected in sequence through pipelines. First hot sex The exchanger 44 is disposed in the air inlet duct 10, and the second water heat exchanger 45 is disposed in the air exhaust duct 20, and is connected to the first water heat exchanger 44 by a pipeline.

The precooling water heat exchanger 41 is provided adjacent to the air inlet of the exhaust duct 20, and is an air precooling device composed of coils. The water inlet end of the precooling water heat exchanger 41 introduces the water source from the second water heat exchanger 45, and the water outlet end of the precooling water heat exchanger 41 is located at a high place and has at least one water spray head extended there.

A water evaporator 42 is disposed in the exhaust duct 20 and is located between the pre-cooling water heat exchanger 41 and the second water heat exchanger 45 for generating a water mist refrigeration device with a heat absorption effect of water evaporation. The opening of the water evaporator 42 extends towards the water outlet end of the pre-cooled water heat exchanger 41 and the water spray head is arranged so that the air passing through the water evaporator 42 produces a water evaporation heat absorption cooling effect, thereby removing impurities in the passing air and transferring the air sensible heat in. In addition, the water evaporator 42 may also be an ultrasonic water mist device.

A water tray 43 is provided below the water evaporator 42 to collect water sprayed by the water spray head. The water tray 43 is connected to the first water heat exchanger 44 through a pipeline, and the water circulation is pushed through a water pump 46 . In addition, the water pan 43 is also connected to a water source installed outside the casing 100 through pipelines to supplement the water required for circulation.

The heat source unit has a heat source device 31, a first heat exchanger 32, and a second heat exchanger 33 connected in sequence to form a circulation pipeline, and circulates the heat medium through the refrigerant flow controller 34. In this embodiment, the heat source unit is an ice-water heat source unit, which means that the medium in the heat source unit is water. The heat source device 31 is provided in the casing 100, using ice water as cold energy and hot water as heat energy. The second heat exchanger 33 absorbs heat from the passing inlet air (functions as an ice water coil), and the first heat exchanger 32 radiates heat to the passing exhaust air (functions as a hot water coil), so that Heat source units become more environmentally friendly. In addition, the first heat exchanger 32 is installed in the exhaust duct 20 adjacent to the second water heat exchanger 45, and the second heat exchanger 33 is installed in the air inlet duct 10 adjacent to the first water heat exchanger 44, so that the precooling water heat exchanger 41. The water evaporator 42, the second water heat exchanger 45, and the first heat exchanger 32 are arranged in sequence along an exhaust direction of the exhaust duct 20.

The energy conversion device formed by the above components has an air-conditioning cold air supply and can adjust the air-conditioning energy according to the needs of the working space. For example, when the indoor temperature is greater than the air-conditioning supply set value, the indoor air is discharged from the exhaust duct 20. The indoor air will first pass through the air inlet of the exhaust duct 20, be filtered by the filter 21, and then flow through the pre-cooled water heat exchanger 41 for heating. Exchange, the pre-cooling water heat exchanger 41 will produce a pre-cooling effect on the air and obtain the first cooling effect. The water in the pre-cooled water heat exchanger 41 flows from the water outlet end to the water spray head at the top, and is sprayed on the water evaporator 42. After the filtration and evaporation of the water evaporator 42, it will produce a water evaporation and endothermic effect with the passing air to transfer The sensible heat in the air causes the air to cool down a second time. At the same time, the water sent out by the water evaporator 42 is also cooled down, and is then sent to the first water heat exchanger 44 through the water pump 46 . When the air passing through the water evaporator 42 flows through the second water heat exchanger 45, the air can remove the heat transferred from the first water heat exchanger 44 in the second water heat exchanger 45. The moisture obtained by the evaporator 42 can be converted into moisture and heat again in the first heat exchanger 32. Therefore, the temperature of the air discharged to the outside is much lower than the temperature of the air discharged directly from the condenser to the outside. It can reduce the thermal pollution of waste heat emission to the environment.

In addition, the circulating water sent from the water evaporator 42 is transmitted to the first water heat exchanger 44 through the water pump 46, and the water temperature at the outlet end of the second water heat exchanger 45 is close to the dew point temperature of the indoor air. Therefore, When the air entering from the air inlet duct 10 flows through the first water heat exchanger 44, because the circulating water is close to the dew point temperature of the indoor air, the air is pre-cooled and cooled first. When the air passes through the second heat exchanger 33 , the heat load of the heat source unit has been reduced, so its operating efficiency can be enhanced to supply the low-temperature and fresh air required indoors and achieve energy saving.

Please refer to Figure 2.

Please refer to FIG. 3 , which is another internal schematic diagram of the portable all-outdoor air energy conversion device. In this embodiment, the first water heat exchanger 44 and the second water heat exchanger 45 form a circulation pipeline. Through the water pump, 462 performs water circulation. The pre-cooling water heat exchanger 41 can be connected to the water pan 43 through the water inlet end. The water in the water pan 43 enters the pre-cooling water heat exchanger 41 through the water pump 461 to provide power, and is sprayed into the water evaporator from the water spray head at the outlet end of the pre-cooling water heat exchanger 41. 42, forming an individual circulation, and the water tray 43 is also connected to a collection of water buckets 47 through pipelines (shown as dotted lines in Figure 3) as a source of water replenishment.

In addition, the heat source device 31 is installed outside the casing 100 and can directly capture moisture from the atmosphere as a medium in the heat source unit. The second water heat exchangers 45 and 32 are provided with water pans 71, and the first water heat exchanger 44 and A water tray 72 is provided below the second heat exchanger 33, and the water trays 71 and 72 can receive air condensation water passing through the heat exchanger (or water heat exchanger). The water pans 71 and 72 can be connected to the external water collection bucket 47 through pipelines, so that the condensed water generated by the heat exchanger inside the casing 100 is captured by the water pump 461 and used as a supplementary water source for the water evaporator 42 to obtain the most effective water vapor inside. utilization.
