Description

DESCRIPTION

U-shaped air handling arrangement in an air handling unit

field of invention

The present invention generally relates to a compact air handling system designed to supply air conditioning to a space including, but not limited to, construction rooms and data center server space. The present invention relates to system design and presentation for air handling unit system applications.

Background

Building designers and developers constantly strive to maximize the space available for usable space and minimize the space used by ancillary equipment, such as, but not limited to, mechanical or electrical equipment and hardware. Designers and developers are also always looking for ways to maximize the use and footprint of the build. This approach has resulted in limitations in the space available for air conditioning equipment, which space may be further confined due to property and building site limitations.

WO-A-2012/011865 discloses an air handling unit comprising at least one air conditioning component, in this case a rotary heat exchanger.

Traditional air handling units have air handling components such as coils, evaporative coolers, filters, etc. and they are one of the main determinants of unit footprint size. These components are typically located throughout the unit perpendicular to the airflow. Such presentations require a suitably sized cross-sectional area, which results in a larger unit footprint including, but not limited to, width. This limits the number of components such as, but not limited to, an air bypass that can be added to the air handling unit when the overall physical size of the unit is restricted.

Past and present compact air handling units have staggered internal components within the air handling equipment to minimize the overall footprint of the air handling unit including, but not limited to, width. Staggered equipment within the air handler can result in higher air pressure drops, resulting in higher energy consumption. Additionally, staggering of components is limited in its scalability and is also limited in the number of components that can be added, such as, but not limited to, an air bypass.

An example of a staggered air handling component kit within an air handling appliance can be described as, but not limited to, two air handling components of equal lengths, shorter than the width of the unit, but extend beyond the midpoint of the unit width, and located perpendicular to the airflow in series with an air handling component on each side of the unit. The free ends of both air handling components furthest from the unit walls are connected to each other by a diagonal wall to form a dividing section between the air entering the treatment component and the conditioned discharge air. In some examples, a branch is added to the diagonal wall connecting the air handling components to each other. The bypass in the staggered arrangement is limited in size, scalability, and effectiveness in providing air bypass, where the air may not effectively bypass the air treatment component(s). This staggered equipment configuration cannot be scaled, as increasing the amount of airflow would require the air handling components to be lengthened to maintain industry normal front speeds, thus increasing the angle between the air handling components. staggered air treatment, resulting in narrow air paths. Narrow air paths increase air pressure drop, where fans require additional power and as a consequence, increase energy consumption. In addition to the aforementioned shortcomings of the staggered component layout, adding an adequately sized and effective air bypass section(s) would require increasing the footprint size of the unit.

Having the ability to bypass the air conditioning component is beneficial in many cases. Such benefits include, but are not limited to, modulating the cooling or heating output of the air conditioning component and improving energy efficiency. Considering the size for the air bypass so that it is maximized ensures optimal modulation capacity and higher energy efficiency. If air bypass is limited due to size, modulation and energy efficiency may be compromised as a result. Traditional air handling unit arrangements and staggered arrangements are limited in bypass capacity and scalability.

Typical air handling components also have front velocity sizing considerations that are integral to their effectiveness and energy efficiency. These components are traditionally installed perpendicular to the airflow path. In large systems with higher airflows and With a limited footprint, installing these components in a traditional perpendicular arrangement will increase forward speed and therefore negatively affect the performance of the air handling component and reduce energy efficiency.

In view of the above industry demands, there is a need to produce compact footprint, high volume airflow air handling units with the ability to combine suitably sized conventional air handling unit air handling components. and, at the same time, allow for optimized air bypass capabilities.

Objects of the invention

It is an object of the present invention to design a high volume airflow, compact footprint air handling unit that exhibits optimal energy efficiency performance and air conditioning modulation capabilities.

The invention uses a U-shaped air handling arrangement and multiple airflow patterns to reduce the overall dimensional footprint while maintaining the air conditioning performances of the unit's air handling components. appropriately sized conventional air handler. The U-shaped air handling arrangement allows for the addition of a full width low resistance air bypass for further modulation of air handling capacity and increased energy efficiency.

Description

The present invention relates to an air handling unit with a U-shaped air handling arrangement that includes a suitably sized bypass and provides an optimized frontal area for reduced velocity through the primary air conditioning components. . This allows for greater energy efficiency, improved temperature modulation capability, and increased airflow within a smaller footprint including, but not limited to, width compared to conventional air handling unit arrangements in the art. above including, but not limited to, staggered component arrangements. Embodiments of the invention allow for multiple independent airflow paths and various flow patterns.

The air handling unit with a U-shaped air handling arrangement is constructed in a similar way to usual air handling unit enclosures, comprising end walls 101, longitudinal walls 102, unit floor 201 , and a unit ceiling 202. The air inlet(s) 103 may be located in the end wall 101, the longitudinal walls 102, the unit floor 201, and/or the unit ceiling 202. A supply fan(s) 115 are located in the supply plenum section 117 and the air is discharged from the air handling unit through the air outlet 116 which may be located in the roof of unit 202, the end wall 101, the floor of unit 201 the longitudinal walls of unit 102. Within the enclosure walls 101, 102 and a supply fan bulkhead 118, are the components that make up the air handling arrangement in the form of u

A primary bypass wall 104, which creates the bottom of the U-shaped air handling arrangement, is parallel to end wall 101 and extends from the floor of unit 201 to the ceiling of unit 202. The width of primary bypass wall 104 is determined for adequate air path clearance between primary air path walls 105 and longitudinal wall 102. Primary bypass wall 104 encompasses a primary bypass damper 109, a filter bank optional bypass 113, and an optional air conditioning component 122 installed in the center. Primary bypass wall 104 connects to a corner connection piece 106 that is curved 90° toward the fan section. The optionally removable corner connection piece 106 can have various bending radii or angles. Typical round flex curve corners 106 , as shown in Figure 1A, facilitate smooth airflow.

Corner connecting pieces 106 connect primary bypass wall 104 substantially perpendicular to primary air path walls 105 that run substantially parallel (i.e., within 20% parallel) to longitudinal walls 102, and extend from the unit floor 201 to unit ceiling 202. In one embodiment, the primary air path walls 105 are located parallel to the longitudinal walls 102. The primary air path walls 105 comprise the air conditioning components 111 that condition air as needed. The air conditioning component 111 may include, but is not limited to, a cold water coil, a DX cooling coil, an evaporator cooler, a hot water heating coil, an electric heating coil, or a humidifier. Additionally, the primary air path walls contain a full size air filter bank 112 and an optional full front air control damper 110. The two primary air path walls 105 are offset along the centerline longitudinal air handling unit at a spacing defined by the primary bypass wall 104 and corner connecting pieces 106, and spaced at a distance optimized to equalize forward velocity over the primary air path walls 105. In a end 120 of primary airpath wall 105, distal to primary bypass wall 104, primary airpath wall 105 connects to a secondary bypass wall 107 that is located substantially perpendicular to the airpath wall primary 105. Secondary bypass wall 107 connects to longitudinal wall 102 at one end 121 and extends from the floor of unit 201 to the ceiling of unit 202. The secondary bypass wall 107 includes a secondary bypass damper 108 that covers most areas of the wall. The secondary bypass wall may also include an optional filter bank 114 and an optional air conditioning component 122. The two secondary bypass walls 107 are offset along the longitudinal centerline of the air handling unit.

The walls 104, 105, 107, the bypass dampers 109, 108, the air conditioning components 111, and the corner connection pieces 106 comprise a divider between the air inlet area 123 and the outflow area. 119. This continuous surface forms the U-shaped air handling arrangement and provides a much larger area for air flow than a cross-sectional surface perpendicular to the air flow. With the U-shaped air treatment arrangement providing more surface area, high volume airflows are achieved within a smaller unit dimension while maintaining conventional industry normal front velocities or reduced through primary air cooling/heating, filtration, and control damper components. The U-shaped configuration allows for additional airflow patterns through the unit with the addition of multiple air bypasses through the additional available space created by the U-shaped air handling arrangement.

The U-shaped air handling arrangement creates additional surface area within the footprint of a reduced size air handling unit while maintaining industry standard face speeds through air handling components. primary air handlers compared to a conventional air handling unit with primary air handling arrangements installed perpendicular to the airflow. Due to the location of the primary air treatment components substantially parallel to the airflow, the airflow must change its direction from longitudinal flow to crossflow to the primary airflow. Also, positioning the dampers and filters in series on the primary air handling components provides equalization of the forward velocity and/or air pressure across the front of the air handling components, maximizing filter performance and cooling/heating efficiency. Maintaining lower or industry normal front end speeds through filters and air treatment components ensures optimum performance, component efficiency, and maintains low air pressure drop which contributes to low horsepower consumption per part of the fan and thus to higher energy efficiency. A reduced footprint, including but not limited to width, offers substantial floor space to provide greater overall airflow by locating multiple units in the limited footprint or maximizing usable building space. In contrast, installing primary air handling components, such as filters and air conditioning components, conventionally perpendicular to the airflow, while attempting to match the width of the air handling unit's footprint air treatment with the U-shaped air treatment arrangement, would result in a significant increase in air treatment front velocities, leading to higher air pressure drop, reduced air conditioning performance, and reduced air conditioning performance. reduced energy efficiency.

In addition, the U-shaped air handling arrangement integrates independently controlled primary and secondary bypass airflows within a small air handling unit footprint. Independently controlled primary and bypass airflow facilitates immense energy savings when air conditioning is not required in the conditioned space supplied by the air handling unit and primary air handling components are completely omitted. Bypass sections within the U-shaped air handling arrangement are sized for industry normal or lowest forward velocity through bypass components, thereby promoting optimum efficiency and better performance. energy efficiency. Having an integrated air bypass allows air to be bypassed from primary air handling components when air conditioning is not needed, eliminating unnecessary running costs and wear and tear on expensive air conditioning equipment, reducing maintenance cycles and increasing the overall efficiency of energy use. Traditional air-handling units with primary air-handling components perpendicular and/or staggered to the airflow restrict the installation of bypass filters and dampers sized for industry-standard frontal speeds, without having to substantially increase the footprint of unit, including, but not limited to, width.

Air handling units with a U-shaped air handling arrangement that provides the component front velocities described above within a small footprint provide significant benefits to end users of the equipment. The air handling unit with U-shape air handling arrangement enables the unit to be multifunctional and efficient to work under various strategies. The entire area of the U-shaped air handling arrangement is easily accessible from both the air inlet and outlet sides, providing operational and maintenance benefits such as, but not limited to, periodic replacement of filters and cleaning of air conditioning components.

The air handling unit with U-shaped air handling arrangement can be equipped with various control instruments and devices, such as, but not limited to, temperature, humidity, air flow, flood sensors and actuators that are common. in the industry to facilitate the control, operation and monitoring of the unit to provide a design airflow volume and air conditioning under various circumstances. Various mechanical hardware and ancillary accessories, such as, but not limited to, lighting, switches, and fire suppression systems, where components are standard in the industry, may be installed in the air handling unit for operation and maintenance of the unit.

In a typical application as shown in Figure 1A, the primary air path walls 105 are used for primary air conditioning and the air conditioning components 111 are sized for conventional or reduced forward velocity. Primary bypass wall 104 and secondary bypass walls 107 are used for bypass airflow. With the conventional air handling unit layout, the options to add multiple airflow and bypass airpaths are very limited or unavailable without further increasing the cross-sectional area and overall footprint of the air handling unit. air treatment. The U-shaped air treatment arrangement achieves industry normal and/or reduced front airflow velocities through the air conditioning components and the addition of full front bypass airflow in a reduced footprint.

Airflow patterns are shown in Figure 1B, Figure 1C and Figure 1D in different modes of operation. Figure 1B shows the primary airflow path 124 when the bypass dampers 109 and 108 are closed. From the air inlet area 123 to the air outlet flow area 119, two separate air paths are formed through each primary air path wall 105 and each air conditioning component 111. Air flows through the primary air treatment components contained within the primary air path walls. primary air 105 sequentially. Since the two primary air paths are mirrored along the unit's longitudinal centerline, a symmetrical layout promotes a uniformly distributed air flow to each air conditioning device 111 over a large area. Installing air filters 112 in parallel juxtaposition to air conditioning device 111 facilitates pressure equalization that promotes uniform air flow throughout the air conditioning device. The airflow exiting each air handling component path is directed towards each other, facilitating good air mixing thereby eliminating the need for an air destratification device. Also, with the optional front dampers 110, one of the main air primary airflow paths can be closed, allowing the unit to stagger the air conditioning devices for more precise adjustment of, but not limitation, control. Of temperature. This stepping capability provides superior performance modulation from a controls standpoint and can help reduce power consumption. Optional front dampers 110 installed in series to the primary air conditioning device 111 can be completely closed, thereby completely eliminating airflow through the primary air path components contained in the primary air path wall 105. . This is a feature that adds additional control potential benefit during times when no conditioning means required additional air so that the air is supplied to the conditioned space.

Figure 1C shows the bypass airflow paths 125 through the primary bypass damper 109 and the secondary bypass dampers 108 with the front dampers 110 fully closed. All airflow is directed through the bypass air path. Bypass dampers 109 and 108 are sized to have an appropriate surface area to provide satisfactory bypass airflow for modulation, and can help alleviate air pressure drop through the treatment unit system. of air resulting from the removal of the primary air conditioning device from the air path. Air conditioning devices such as fin and tube coils, evaporative coolers, etc. have higher pressure than low speed dampers. Decreasing the air pressure drop reduces the power consumption of the fan and therefore increases the energy efficiency of the system. When the bypasses are equipped in this manner, similar to the primary airflow pattern, independent airflow can be achieved through each air bypass path by opening or closing the bypass dampers. 108, 109, allowing great flexibility in controlling bypass airflow.

An example of using bypass airflow is during free cooling operation. Free cooling is used when outside air conditions are favorable to supply the cooling media necessary to provide the proper controlled climate within the conditioned space maintained by the air handling unit. During times of free cooling, air can be completely bypassed around the primary air handling components by fully closing front damper 110, and opening bypass dampers 108 and 109, eliminating unnecessary wear on, but not limited to, the front dampers. expensive cooling/heating and filtration components, greatly reducing maintenance cycles, including but not limited to filter changes. The air handling unit with the U-shaped air handling arrangement allows closure of the primary air path as it includes a full air bypass spanning the entire front of the air handling unit enclosure. air. The entire bypass air area contained within the U-shaped air handling arrangement includes forward velocities through filter banks and bypass dampers within industry standard velocities, resulting in a energy efficiency equal to, or better than, when the air travels through the primary air path treatment components contained within the primary air walls 105.

Increased energy efficiency is an additional benefit of eliminating airflow through the primary airpath walls 105 during periods of operation when the controlled space does not require additional air conditioning.

Figure 1D illustrates the free-flowing airflow path 126 through the primary airpath treatment components and through the primary and secondary bypass paths. Optional primary air handling front dampers 110, and bypass dampers 108, 109 may be, but are not limited to, modulated and fully closed or fully open to provide a high level of air conditioning climate control. In a case, where free cooling is favorable due to adequate outside air conditions, all U-shaped air treatment arrangement dampers 108, 109, 110 can be fully opened to relieve air pressure drop in the air handling unit system. As mentioned above, reducing the air pressure drop in the system can result in better energy efficiency due to less power consumption by the fan. In addition to the airflow exiting each air handling component path mentioned above, the inclusion of the bypass airflow from the primary bypass airwall 104 intertwines with the primary airflow treatment walls 105 mixed more evenly in the air handling unit with U-shaped air handling arrangement, thus eliminating the need for an air destratification device. In another case, such as, but not limited to, emergency operation where maximum airflow from the unit is required. air handling unit, opening all front and bypass dampers significantly reduces resistance to airflow through the air handling unit, thereby supplying substantially more airflow to the conditioned space maintained by the air handling unit. air treatment.

Independent airflow paths through front dampers 110 and bypass dampers 108 and 109 allow for various operating strategies of the air handling unit. An example is a unit with dual operating modes that uses the primary airflow path as the cooling mode and the bypass airflow path as the heating mode, and vice versa. This could be accomplished by adding an air conditioning device 122 to the bypass air path.

The U-shaped air handling arrangement can be reversed with respect to the direction of air flow in the air handling unit as shown in Figure 3A, where the primary bypass wall 104 is located farthest from the air handling unit. the air inlet(s) 103, and the secondary bypass wall 107 is located at the front facing the airflow inlet direction. The installation of components on the primary air path walls 105 is adjusted so that air flows through the air filtration bank 112 and the air conditioning component 111 in sequence. At bypass walls 104, and 107, optional air conditioning components 122 are installed downstream of bypass filter banks 113, and 114. Filter banks 112, 113, and 114 are installed upstream of dampers. 110 front covers , and 108109 bypass dampers to provide trouble-free front access for filter replacement. The airflow pattern is indicated in Figure 3B for the primary airflow path 124, in Figure 3C for the bypass airflow paths 125, and the free-flowing airflow path 126. Similar operation as mentioned above of the front dampers 110 and bypass dampers 108 and 109 is activated to provide various flow patterns.

The U-shaped air handling arrangement can be scaled as shown in Figure 4, where multiple U-shaped air handling arrangements are connected to secondary bypass walls 107. The scalability of the treatment arrangement U-shaped air vent provides additional flexibility to increase airflow, independently controlled air handling components, and various flow patterns available.

The above demonstrates a U-shaped air handling arrangement air handling unit application where primary and bypass air flow is achieved within a limited footprint, while maintaining air flow rate. Industry preferred normal or reduced air through air conditioning components. U-shaped air handling arrangement promotes good airflow mixing, provides the ability to alleviate air pressure drop throughout the system, leading to increased energy efficiency and airflow paths. independent air.

The scope of the present invention is not limited by the specific embodiments described herein. Indeed, various modifications of the invention in addition to those described herein will be apparent to those skilled in the art from the foregoing description. Such modifications are intended to come within the scope of the appended claims.
