2. Description of the Prior Art
In recent decades there is a growing awareness of the concept of environmental protection. However most preventive measures focus on the macro level. The pollution issues that are not very notable often are overlooked, such as the pollution resulting from air conditioning. In short, most improvements on air conditioning systems at present mainly focus on lower energy consumption, noise reduction, humanized control, mood enhancement, dehydration, indoor air purification, and the like. While the issue of indoor air purification has attracted a lot of attention, the impact of polluted air discharged from the air conditioning or operation space (such as plants, chicken farms, and the like) to the environment often is neglected. Some systems have used filters or other methods to get clean air conditioning space. But dusts, fibers and other ionized matters generated in the air conditioning space are discharged outdoors during air conditioning operation. Moreover, due to over-utilization of lands, building density increases greatly. The so called fresh air intake of building or during industrial process often is the polluted air discharged somewhere else. This creates a secondary public hazard and contamination, and becomes one of the air pollution sources. To prevent the secondary public hazard, a water-filtered air purifying and energy saving apparatus was proposed in R.O.C. patent No. 139014. It has a partition to divide a upper air vent that discharges the heated air and a lower vent that draws the outdoor air. However, the heated air discharged through the upper air vent is easily drawn into the apparatus through the lower air vent. As a result, the energy saving effect suffers. This is its big disadvantage.
In view of the aforesaid disadvantages, the present invention aims to provide a water total heat exchange energy reclaiming apparatus to purify air quality, increase energy saving effect and facilitate installation thereby to improve environmental air and save energy.
The invention includes a first chassis and a second chassis that are separated but connected through a piping. The first chassis includes a first air duct, a water vaporizing device, a first heat exchange coil and a first fan. The second chassis includes a second air duct, a cold water heat exchange tube, a second heat exchange coil and a second fan. The water vaporizing device is connected to a water level controller and a first pump through a piping, and connected to the cold water heat exchange tube to form a closed circulation piping to reclaim cold and heat energy. The first heat exchange coil is connected to a second pump through another piping, and connected to the second heat exchange coil to form another closed circulation piping to release or reclaim cold and heat-energy. By means of the separated first chassis and the second chassis, discharge airflow and return airflow do not mixed. Hence operation efficiency can be maintained. The configuration can be arranged according to environment requirements. Installation is more convenient.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

The first chassis 21 includes a first air duct 210, a water vaporizing device 211, a first heat exchange coil 213 and a first fan 214 on one side.
The water vaporizing device 211 aims to vaporize and filter water, and has one end connecting to a cold water discharge end 2212 of a cold water heat exchange tube 221 of the second chassis 22 through a second piping L2. The water vaporizing device 211 has a water tray 212 on the bottom. The water tray 212 has one side connecting to a water level controller 24 and a first pump 25 through a first piping L1, and also connected to a cold water intake end 2211 of the cold water heat exchange tube 221.
The first heat exchange coil 213 is connected to the second chassis 22 through a third piping L3 and a fourth piping L4. The third piping L3 has a second pump 23.
The first fan 214 aims to convey airflow.
The second chassis 22 includes a second air duct 220, the cold water heat exchange tube 221, a second heat exchange coil 222, and a second fan 223 on another side.
The cold water heat exchange tube 221 contains a heat exchange tube with the cold water intake end 2211 on one end and the cold water discharge end 2212 on another end, and is connected to the water vaporizing device 211 through the first and second piping L1 and L2.
The second heat exchange coil 222 is connected to the first heat exchange coil 213 of the first chassis 21 through the third and fourth piping L3 and L4 to form a closed circulation piping.
The second fan 223 aims to convey airflow.
By means of the construction set forth above, when in use for cooling air circulation (referring to
As previously discussed, the air cooled by the water vaporizing device 211 flows to the first heat exchange coil 213 through the first air duct 210. The first heat exchange coil 213 consists of a plurality of tubes which contain a circulation medium (such as water, refrigerant or the like). Through the heat exchange function of the circulation medium in the first heat exchange coil 213, the air passing through the first heat exchange coil 213 absorbs heat and has a higher temperature. Hence the air discharged from the indoor side I is purified without polluting the environment. Meanwhile, the reclaimed cold energy can lower the temperature of the circulation medium in the first heat exchange coil 213 to save the energy of second heat exchange coil 222.
The air in the outdoor side O is drawn by the second fan 223 to enter the second heat exchange coil 222 through the second air duct 220. As the second heat exchange coil 222 is connected to the first heat exchange coil 213 through the third and fourth piping L3 and L4, and the third piping L3 has the second pump 23, the cold energy generated by the heat exchange of the first heat exchange coil 213 is sent to the second heat exchange coil 222 to pre-cool the air entering from the outdoor side O. The pre-cooled air further is cooled by the cold water exchange tube 221 to save energy.
When the invention is in use for warm air circulation (referring to
The first chassis 21 and the second chassis 22 are configured separately, and may be installed on different locations according to environment and space conditions. Therefore the discharged air can be prevented from drawn indoors to avoid airflow mixing. And air quality can be maintained as desired.

The water level controller 24 has a float ball 241 to control water consumption required in the circulation. A water intake tube 242 is provided to replenish water for circulation. A water discharge tube 243 is provided to discharge the impurities and extra circulating water. The water level controller 24 further is connected to the first pump 25 to send the water in the water level controller 24 to the cold water intake end 2211 of the cold water exchange tube 221 through the first piping L1. The water flows from the cold water discharge end 2212 to the top of the water vaporizing device 211 through the second piping L2 to complete one cycle of water circulation.
