Taking the duct 61 as an example, the exhaust duct 20 is provided with a connecting portion 61 to be combined with one end of the duct 60, The other end of the air pipe 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 total external air energy conversion device can be easily installed. The air inlet of the air inlet duct 10 and the air outlet of the air outlet 20 are respectively provided with filters 11 and 21 to filter the odors and harmful gases in the air. In addition, the through fans 12 of the air inlet 10 and the exhaust duct 20 , 22 makes the air flow towards the indoor or outdoor space.

The water heat cycle heat exchanger group is a circulating pipeline composed of a pre-cooling 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. The first water heat exchanger 44 is arranged in the air inlet duct 10, and the second water heat exchanger 45 is arranged in the exhaust duct 20 and is connected to the first water heat exchanger 44 by a pipeline.

The pre-cooling water heat exchanger 41 is provided with an air inlet adjacent to the exhaust duct 20, which is an air pre-cooling device composed of coils. The water inlet of the pre-cooling water heat exchanger 41 is introduced into the water source from the second water heat exchanger 45, and the water outlet of the pre-cooling water heat exchanger 41 is located at a high place and at least one water spray head is extended.

A water evaporator 42 is arranged in the exhaust duct 20 and is located between the pre-cooling water heat exchanger 41 and the second water heat exchanger 45 to produce a water mist refrigeration device that evaporates and absorbs heat. The opening of the water evaporator 42 is directed toward the water outlet of the pre-cooling water heat exchanger 41. A spray head is arranged so that the air passing through the water evaporator 42 produces water evaporation and heat absorption cooling effect, thereby removing impurities in the passing air and transferring the air Sensible heat. In addition, the water evaporator 42 may also be an ultrasonic water mist device.

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 the heat medium is circulated through the refrigerant flow controller 34. In this embodiment, the heat source unit is an ice-water heat source unit, meaning that the medium in the heat source unit is water, and the heat source device 31 is arranged in the casing 100, using ice water as cold energy and hot water as heat energy. The second heat exchanger 33 absorbs heat for the passing air (the function of an ice water coil), and the first heat exchanger 32 emits heat for the passing exhaust gas (the function of a hot water coil), so that The heat source unit becomes 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 intake duct 10 adjacent to the first water heat exchanger 44, so that the pre-cooling water heat exchanger 41.

The energy conversion device formed by the above-mentioned components has an air-conditioning cold air supply, and the air-conditioning energy can be adjusted according to the demand of the working space. For example, when the indoor temperature is greater than the set value of the cold air supply, the indoor air is discharged from the exhaust duct 20, and the indoor air will first pass through the air inlet of the exhaust duct 20 and be filtered by the filter 21, and flow through the pre-cooling water heat exchanger 41 for heating. Exchange, the pre-cooling water heat exchanger 41 will have a pre-cooling effect on the air to obtain the first cooling effect. The water in the pre-cooling water heat exchanger 41 is sprayed on the water evaporator 42 from the outlet end to the high water spray head. After the filtration and evaporation of the water evaporator 42, it will produce water evaporation and heat absorption effect with the passing air to transfer The sensible heat in the air causes the air to cool down a second time, and at the same time, the water sent from the water evaporator 42 is also cooled, and then sent to the first water heat exchanger 44 by the water pump 46. When the air passing through the water evaporator 42 passes through the second water heat exchanger 45, the heat transferred from the first water heat exchanger 44 can be removed, and the moisture obtained in the water evaporator 42 can be In the first heat exchanger 32, the humidity and heat are converted again, so that the temperature of the air discharged to the outside is much lower than that of the conventional air directly discharged from the condensed gas, which can reduce the thermal pollution of the waste heat to the environment.

In addition, the circulating water sent from the water evaporator 42 is transferred to the first water heat exchanger 44 by 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, the circulating water is also close to the dew point temperature of the indoor air, so that the air is pre-cooled and cooled, and 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 in the room, and achieve the purpose of energy saving.
