Description

TECHNICAL FIELD

[0001] The present application relates to the field of ventilation and air conditioning, more particularly to a split-flow plate heat recovery system. BACKGROUND

[0002] Heat recovery as a way of energy saving and emission reduction in the field of ventilation and air conditioning is a general term for energy recovery, which can be divided into cold recovery and heat recovery. When the dirty air in the room is removed in summer, the cold air in the room is also taken away, and when the room is supplied with fresh air, the high temperature outside is taken into the room. In order to let the cold in the room be taken out as little as possible, the energy exchange between the exhaust air and the fresh air is used, and the heat exchange core is used as the medium for energy exchange. The heat exchange core transfers the heat of cold and hot air by being constructed close to the cross and not communicating with each other. In summer, the cold is recovered, and in winter, the heat is recovered. In addition to temperature, humidity also affects the comfort of the room. While the heat exchange core exchanges heat, the core with the function of absorbing moisture also absorbs and discharges water in the air. The heat recovery containing only heat exchange is called sensible heat recovery, and the heat recovery containing heat and moisture exchange is called total heat recovery.

[0003] When the indoor fresh air is exchanged, heat recovery can maintain the indoor air temperature and humidity with small fluctuations, or reduce the subsequent cooling and dehumidification load or heating and humidification load. Because the single plate heat exchange core has an upper limit of air volume, when a large amount of fresh air is required, the most direct way to use plate heat recovery is to combine multiple fresh air exchanger units, and the air pipe branching and merging, the cooling water inlet and outlet pipe, the drain pipe and the like are also branched and merged outside the unit. However, after combining multiple fresh air exchanger units, the air pipe system and the water pipe system are relatively complex, the air pipe layout is easy to interfere, and the fan start-stop is also relatively dispersed.

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] like Figures 1 to 16 As shown below, the structure and function of a flow divider plate heat recovery system will be described in detail.

[0041] A diverter plate type heat recovery system includes an air inlet chamber and an air outlet chamber arranged vertically. A fresh air inlet is provided on one side of the air inlet chamber and a return air inlet is provided on the other side. An air supply outlet is provided on one side of the air outlet chamber and an exhaust outlet is provided on the other side. A filter heat exchange component is installed in the middle of the air inlet chamber through a heat exchange core and a baffle assembly 3. A filter heat exchange component is installed in the middle of the air outlet chamber through a heat exchange core and a baffle assembly 3. Fresh air enters the air inlet chamber through the fresh air inlet, passes through the filter heat exchange components in the air inlet chamber and the air outlet chamber, and is discharged from the air supply outlet. Return air enters the air inlet chamber through the return air inlet, passes through the filter heat exchange components in the air inlet chamber and the air outlet chamber, and is discharged from the exhaust outlet.

[0042] This system uses a combination of upper and lower heat exchange components, a plate heat recovery heat exchange core 1, and a plate primary filter 2 to achieve heat exchange between fresh air and return air, effectively recovering cold or heat energy and significantly reducing the energy load of the subsequent air conditioning system. Sensible heat or total heat recovery functions can be selected according to needs to adapt to the temperature and humidity regulation requirements of different seasons and improve indoor comfort.

[0043] When using, such as Figure 6 and Figure 7 As shown, by utilizing the separation and merging of fresh and return air, and by setting up an air duct structure between the air inlet chamber and the air outlet chamber, the outdoor fresh air and indoor return air are separated and enter the upper and lower filter heat exchange components respectively. The return air and fresh air in the same filter heat exchange component go through their own independent cross channels and exchange heat. After heat exchange, the airflow of the return air and fresh air in the filter heat exchange component in the air inlet chamber merges after entering the filter heat exchange component in the air outlet chamber. The return air is discharged by the exhaust fan, and the fresh air is cooled by the surface cooling coil and then sent out by the supply fan. In winter, the fresh air is heated by the surface cooling coil and then sent out by the supply fan.

[0044] The internal air duct diversion design separates the fresh air and return air into the upper and lower filter heat exchange components, achieving efficient handling of ultra-large fresh air volumes without relying on multiple unit combinations, thus simplifying the system structure. It also solves the problems of complex duct and water pipe systems and interference in traditional multi-unit combinations. The integrated cavity design integrates the air inlet cavity, air outlet cavity, filter heat exchange components, and fan into a single system, resulting in high space utilization and easier installation and maintenance.

The other path enters the left V-shaped diversion channel 9-1 through ventilation hole ⑤, and enters the second filtration and heat exchange cavity through the left V-shaped diversion channel 9-1 and ventilation hole ⑩. After filtration and heat exchange through the plate primary filter 2 and the plate heat recovery heat exchange core 1, it moves to the surface cooling coil 11. The two fresh air paths converge in the surface cooling coil 11 and are discharged through the blower 12.

[0053] The return airflow enters the return air cavity through the return air inlet and splits into two paths. One path enters the first filter heat exchange cavity through the ventilation hole ①, and after being filtered and heat-exchanged by the plate primary filter 2 and the plate heat recovery heat exchange core 1, it moves to the return exhaust fan 10 through the ventilation hole ⑦. The other path enters the second filter heat exchange cavity through the ventilation hole ⑥ and the right-side V-shaped diversion channel 9-2, and after being filtered and heat-exchanged by the plate primary filter 2 and the plate heat recovery heat exchange core 1, it moves to the return exhaust fan 10. The two return air paths converge at the return exhaust fan 10 and are discharged through the return exhaust fan 10.

[0058] The heat exchanger core lower slide 3-2, heat exchanger core upper slide 3-3, heat exchanger core left slide 3-6, and heat exchanger core right slide 3-8 form a slide space for the plate heat recovery heat exchanger core 1, allowing the plate heat recovery heat exchanger core 1 to be freely inserted and removed, facilitating the installation and replacement of the plate heat recovery heat exchanger core 1.
