Snowy, invented - a novel and useful = = said: Book: Description of the fresh air handling system: converter. This application claims priority to US Application Serial No. 12/804,31, the entire disclosure of which is incorporated herein by reference. [Prior Art] The heat exchanger itself is not a new technology. The utility of the fresh air heat exchanger of the present invention is to provide heating, treatment and purification of air from a building. This is done via several successive stages in a complete unit. The fresh air heat exchanger is unique in that it automatically switches modes of operation when the building is used or not in use. The fresh air heat exchanger of the present invention is controlled by the existing temperature control system of the building t. It can be self-controlled or a combination of both. The standard fresh air heat exchanger only circulates when the building is not in use. This unit removes the dirty air, uses the heat from the dirty air to warm the incoming fresh cold air, and then the dirty air is discharged, while the preheated fresh air is heated by a hot water coil, and It is optionally purged by a UV cell and then released into the chamber. U.S. Patent No. 5,632,334 issued to G.S. [Summary of the Invention] 4 201211471 At the same time, the smoke magazine has a mode of switching the fresh air heat exchanger with hot air and cold air in the system. The device is constructed of a front portion having a top bottom and a distal end, a back cover. An opening is located in the inner back of the casing, and the inner back is a fresh air external σ 涵 venting plate. There is also a first line to carry the fresh air from the venting plate to the -th heat recovery ventilator. An X device includes an open grille at the inner front portion near the bottom, which is a dirty air opening grille 'and is disposed inside the single shell, and a system for abutting and aligning the grille for the Filter for dirty air. A second pipe carries the smashed air to a second heat recovery ventilator, and the second heat recovery ventilator is connected in a series to the first 孰 recovery ventilator '" Air that has recovered heat is carried through the ventilator to the outside. There is a fourth, #Η rolling carrying ^ 弟四官道 to bring the fresh air supply to the heating zone and into the room through the air vent. This air vent is tied to the top of the casing. By means of a variable speed electric (four), helium gas is conveyed through the heating zone β by means of an electric blower and electrical components for electrifying the blower and the fan, the fresh air and the dirty air being simultaneously moved. The advantages of the devices of the invention of the present invention include, but not, the height of the surface layer is discharged, and the person is sucked above the ground to exclude the picking of the remaining objects and the like by the farmer 'excluding the buildings*', eight The ventilating tube used in the slab, excluding most of the damper and the damper controller, uses an air cleaner system in the flowing air for use in the month 及 _ and 5 201211471. [Embodiment] FIG. 1 is a perspective plan view of a fresh air heat exchanger 2. In this case, the new hot air father has changed the 2 series. An intake grill 60, shown in this figure, is attached to the intake elbow 44 that supplies fresh air to the unit 2. Also shown is the supply of return air to the air vents 52 in the chamber. An air intake port 82 for indoor air passes through the bottom front face 14, which is filtered and then guided into the fresh air heat exchanger 2. The hot water coil 34 is located at the top of the heat exchanger 72 casing 18. The fresh air heat exchanger 2 is electrically controlled by a junction box 38 and a switch fuse 40 via a conduit 42 and an electrical box 36. Provide power. 2 is an exploded view of the fresh air heat exchanger 2. This embodiment also includes a UV photocell 62. The UV phototube employs an oxidation technique which is a high intensity broadband UV tube (10-300 nm) in a hydrated catalytic matrix cell. Low-order ozone is produced in the photocell, and most of it is converted into no-load hydroperoxides, superoxide ions, ozonide ions, and hydroxides. The bulb is mounted in a multi-tube to prevent any glass or mercury from leaking. The air is purified by the uv photocell 62 after it is heated by the hot water coil 34. Figure 3 is an exploded view of the fresh air heat exchanger 2. This figure shows the components of the new sheep two-hot hot parent converter 2. The fresh air heat exchange piano has a top plate 6, two end plates 8, a bottom plate 1 and an inner wall 12. The unit 2 is seated on a bottom portion including a bottom front face 14 and a bottom back face 16. The front face 14 of the bottom of the shai has vents 82 therein, which function as one of the air inlets 82 of an indoor air. The air drawn from the chamber is filtered by the teardrop 50 before it advances to the heat exchangers 72 in the casing 18. The filter is supported by the teardrop arms 48 attached to the bottom plate 1 . Support passages 20 are located at the top of the bottom plate and support the casing 18. The coil supply line 22 supplies air to the coil 34 for further heating. When the air is drawn in from the bottom 10, it flows into the indoor air duct 24' into the heat exchangers 72 in the casing 18 where it is passed by the incoming fresh air to preheat the Fresh air is then discharged through the discharge port 78. The indoor air duct 24 is connected to the casing 18 via a set of soil 28 and a suction belt 26. The circulation of the air inlet and the forward inflow and outflow δH fresh air heat master 2 is provided by the blower 3 〇. The blower 30 introduces air from the bottom front face 14 through the filter; 50, through the indoor air duct 24, into the heat exchangers 72 in the casing 18, and then discharges it. The fresh air is drawn into and through the indoor air that preheats the fresh air. From here, air is forced through the coil supply line 22, through the hot water coil 34, through the UV phototube 62, and then the currently heated and cleaned air reaches the chamber. The indoor air is advanced through the hot parent 7 2 ' to take heat and then transfer the heat to the fresh incoming outside air. Figure 4 is an internal view of the external air intake 68 'heat exchanger 72, indoor air duct 24 and electrical control system 7'. This picture can be clearly seen outside the picture. The helium air inlet includes an air chamber 64, an intake elbow 44, a back floor 7 201211471 arm and a venting plate 54 (not shown) to introduce air from the outside. The heat exchanger 72 includes a front bottom 14 and a rear bottom 16 that incorporate a filter 50 and support the casing 18. The casing 18 supports the blower 30 (not shown) and the hot water coil 34. Also shown is the coil supply line 22. Mounted in the top portion 6 is the air vent 52 that recirculates the heated and purified air into the chamber. Fig. 5 is a back view showing the fresh air heat exchanger 2 of the external or external air intake port 68. The outer louver 54 is supported by a support plate 74 and separated by a partition plate 76. The intake elbow 44 is attached to the support plate 74 to draw air through the louver 54 and into the elbow 44, and then into the intake air chamber 64 to be advanced into the enclosure 18 It is used in the heat exchangers 72 through which the indoor air is preheated. The support plate 74 also has another opening 78 that is aligned with the discharge system 80. The fresh air heat exchanger 2 discharges indoor air through the discharge system 80 and exits the discharge port 78. The casing 18 has a filter 50 for entering fresh air and is also a filter for the preheated air. Fig. 6 is a schematic view of the flow of air in the fresh air heat exchanger 2. The indoor air is drawn into the front bottom portion 14, passes through the filter 50, and then enters the living microfluid 18. The outside air is drawn through the external vent 54, into the intake elbow 44, into the intake air chamber 64, and into the enclosure 18. The fresh outside air is heated by the heat exchanger 72. The air is then drawn into the blower 3 〇 and into the coil supply line 22, and then enters the heated water coil 34 8 201211471 where it is heated and then enters it more than The uv photocell 62' is purified and then passed through the air vent 52 and back into the heated and purified interior. The dirty indoor air is removed through the discharge port 78 of the discharge system 80. Figure 7 is a top plan view of the fresh air heat exchanger 2. This figure shows the air intake port 68, the air chamber 64, the hot water coil 34, and the UV photocell 68. The focus here is on the relationship between the hot water coil 34 and the x-ray photocell 68 to indicate that the air has been heated and purified before it is released into the chamber. Figure 8 is a schematic illustration of air flow in one of the devices of the present invention. The solid line indicates that the outside air entering the system 2 first passes through the heat exchanger 72, and then passes through the hot water coil 34, as it enters the coil supply line 22, and then reaches the UV phototube 62, which then flows back into the system. The interior. This is the fresh air; gas circulation. The solid line, in conjunction with the dashed line, indicates that the indoor air is filtered at the filter 5 流动 flow cycle 'and subsequently reaches the blower 30 where it is moved to the coil supply line 22 ° which is then in the hot water coil 34 Heating, advancing through the UV phototube 62 and back to the heated and purified chamber. This is a loop that is not used. Another cycle indicated by the solid line in combination with the star is the discharge. The cycle is synchronized to the first cycle in which the room air is passed through the heat exchangers 72 to warm the fresh incoming outside air before it is discharged. The indoor air is then discharged. In the mode of use of the building, there are three operational phases and one phase of using 201211471 in the non-use mode of the building. In this first phase, the outside air is forced through the outer venting plate 54 and through the elbow 44 into the fresh air heat exchanger 2. The fresh air is then drawn into a heat recovery venting branch while 'dirty warm air from the interior of the building is introduced into the bottom front of the fresh air heat exchanger 2 through a grid of peaches, the air being on the grid At 82, the particles were first filtered. The filtered air enters the indoor air duct 24 in the fresh air heat exchanger 2, and then advances through the heat recovery ventilator 4 where it is discharged to the outside via the external ventilating panel 54. The dirty warm air is constantly being replaced by a considerable amount of external fresh air. The heat recovery ventilator 4 can meet the fresh air demand of the building' and can have at least 25 cubic feet per minute. Since the two air streams pass through the heat recovery ventilator 4, they do not mix. They advance through the air passing H 5G on either side of the aluminum heat exchange disc in the casing 18, which transfers heat from the outflowing air to the inflowing air. This allows heat from the building to be stored and prevented from being lost to the outside. The concentrated effluent is placed at the bottom of the heat recovery ventilator 4 below the aluminum enamel core. The effluent then proceeds through the fresh air heat exchanger 2 where a sump pump is located. The pump is then discharged to the existing exhaust system of the building. Once the air has been warmed by the heat recovery ventilator 4 during the first phase, and by the hot water coil 34 disposed in the fresh air heat exchanger 2 above the heat recovery ventilator 4, This second phase begins when an additional heating of the air is achieved. The hot water coil 32 is connected to the building's 201211471 hot water system and is capable of coping with up to 20,000 BTU of heat loss from the room. A variable speed control fan or blower 3 〇 continuously draws the conditioned heat recovery ventilator 4 air through the hot water coil 34 and into the chamber. After the second stage, before the heated air enters the chamber from the heat recovery ventilator 4, the third stage begins, which advances through a photocell 62 disposed downstream of the hot water coil 34. The photocell 62 is constructed using an oxidation technique which is composed of a high intensity wide spectrum UV tube (10 Å to 3 Å) in a photocatalyst of a hydrolysis catalytic substrate. The lower order ozone is produced in the photocell. The majority of it is converted into no-load hydroperoxides, superoxide ions, ozonide ions and hydroxides. The UV bulb is mounted in a multi-tube to prevent any glass or mercury from leaking. In addition, the entire assembly is housed in a protective metal photocell. By reducing odors, air pollutants, chemical odors, smog, mold bacteria, and viruses, this photocell eliminates morbidity: the danger of building symptoms. The fresh air heat exchanger 2 also has a non-use phase of the building at which the heat recovery ventilator is bypassed unused. The indoor air passes through a grid 82 that is filtered through the bottom to enter the fresh air heat exchanger 2, is heated by the hot water coil, and is recirculated back into the chamber by the variable speed fan. Following the other 2 - the unique feature is that the inlet and outlet are much higher than the ground level. Conventional technical units have their outlets at the ground level and the air intakes so that they receive grass residues and snow, causing various internal problems in such units.
