Description

Technical Field

[0001] This utility model relates to the field of drying room technology, and in particular to a constant temperature room heat recovery system. Background Technology

[0002] One type of drying room has a conventional air heat exchanger installed independently inside. This type of heat exchanger uses plate cross heat exchange, which has low heat exchange efficiency and can also lead to uneven air exchange in the room.

[0003] Publication No. CN117781614A discloses a heat source for a drying room, including a housing (1) and a burner (2). The housing (1) is provided with a partition (3) that divides the housing (1) into a dehumidification chamber (4) and a heating chamber (5). A horizontal plate (6) is provided at the lower end of the dehumidification chamber (4) to separate an air inlet chamber (7). The burner (2) is located in the heating chamber (5) for heating the air in the heating chamber (5). A fresh air valve (8) is provided on the housing (1) at the air inlet chamber (7). A return air vent (9) is provided on the housing (1) at the heating chamber (5). A waste heat recovery body (10) is also provided inside the housing (1). The waste heat recovery body (10) has a fresh air inlet (11), a fresh air outlet (12), a return air inlet (13), and a return air outlet (14). The fresh air inlet (11) is connected to the air inlet chamber (7), the fresh air outlet (12) is connected to the heating chamber (5), the return air inlet (13) is connected to the heating chamber (5), and the return air outlet (14) is connected to the dehumidification chamber (4).

[0004] In this technical solution, a heat source is used to heat the air in the drying chamber, providing hot air for the drying room. This heat source includes the chamber body and its internal burner. The chamber body is further divided into a dehumidification chamber and a heating chamber, and a waste heat recovery unit is also installed inside the chamber for heat exchange. The inclusion of various auxiliary components, including the burner and waste heat recovery unit, within the chamber body results in a complex overall structure and limited efficiency in heat recovery from the drying chamber and circulating pipes, leading to relatively high energy consumption. Utility Model Content

[0005] This invention addresses the aforementioned problems by providing a constant temperature room heat recovery system. With simple modifications to a conventional drying room structure, it can improve the heating (cooling) efficiency of the main unit and efficiently recover and recycle heat.

[0006] This utility model adopts the following technical solution: a constant temperature room heat recovery system, including a drying room and a heating and cooling unit, wherein the air outlet of the drying room is connected to the air inlet of the heating and cooling unit through a return air duct, and the air outlet of the heating and cooling unit is connected to the air inlet of the drying room through a supply air duct, characterized in that a sliding heat recovery device is installed on the return air duct, wherein the exhaust port and fresh air inlet of the sliding heat recovery device are both located on the side of the return air duct, the exhaust port is closer to the air outlet of the drying room, and an exhaust fan is installed at the exhaust port of the sliding heat recovery device.

[0007] Preferably, the exhaust vent and fresh air inlet of the translational heat recovery unit are both located on the same side of the return air duct.

[0008] Preferably, a baffle plate is installed inside the return air duct at the boundary between the exhaust port and the fresh air inlet.

[0009] Preferably, the fresh air inlet of the translational heat recovery unit is equipped with an air valve.

[0010] Preferably, the heating and cooling unit includes an intake fan, an exhaust fan, a condenser, and an evaporator, with the evaporator located near the exhaust port of the translational heat recovery unit.

[0011] Preferably, the air inlet fan is positioned adjacent to the condenser, the air outlet fan is positioned adjacent to the evaporator, and the air outlet fan is located on the lower outer side of the heating and cooling unit.

[0012] This invention achieves high-efficiency heat exchange at low temperatures by installing a sliding heat exchanger on the return air duct and utilizing medium evaporation heat exchange. The exhaust and intake air of the sliding heat exchanger are located in the same return air duct, allowing fresh air to mix with the circulating air and ensuring uniform distribution of fresh air in the drying room. By rationally positioning the air vents, the exhaust air can re-enter the evaporator of the heating / cooling unit, thereby improving the unit's heating (cooling) efficiency.

Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] like Figure 1 and Figure 2 The illustrated constant temperature chamber heat recovery system includes a drying chamber 1 and a heating and cooling unit 10. The drying chamber can be a mushroom drying room or other drying room for materials requiring drying. The air outlet of the drying chamber is connected to the air inlet of the heating and cooling unit 10 via a return air duct 3. The air outlet of the heating and cooling unit 10 is connected to the air inlet of the drying chamber via a supply air duct 2. A sliding heat recovery device 4 is installed on the return air duct 3. The exhaust port 14 and the fresh air inlet 5 of the sliding heat recovery device 4 are both located on the side of the return air duct 3, with the exhaust port closer to the air outlet of the drying chamber. An exhaust fan 6 is installed at the exhaust port of the sliding heat recovery device. This technical solution mainly utilizes a sliding heat exchanger installed on the return air duct to achieve low-temperature, high-efficiency heat exchange through medium evaporation heat exchange.

[0018] The exhaust vent and fresh air inlet of the shift-type heat recovery unit are both located on the same side of the return air duct. A baffle plate 12 is installed inside the return air duct at the boundary between the exhaust vent and the fresh air inlet. The baffle plate prevents interference between the intake and exhaust air, ensuring uniform and smooth airflow without turbulence.

[0019] Specifically, an air valve 13 is installed at the fresh air inlet of the shift-type heat recovery unit. The air valve facilitates the adjustment of the air intake switch.

[0020] In one embodiment, the heating and cooling unit includes an intake fan 11, an exhaust fan 8, a condenser 9, and an evaporator 7, with the evaporator 7 positioned near the exhaust port of the shift-type heat recovery unit. This ensures that most of the hot air exhausted from the exhaust port is drawn into the evaporator, improving evaporation efficiency and thus increasing the heating efficiency of the unit.

[0021] Specifically, the air inlet fan 11 is located adjacent to the condenser, and the air outlet fan 8 is located adjacent to the evaporator 7. The air outlet fan 8 is located on the lower outer side of the heating and cooling unit.

[0022] The working principle of this utility model is as follows: The translational heat recovery unit is installed on the side of the return air duct between the drying room and the main heating and cooling unit. The side of the duct is connected to the exhaust port of the translational heat recovery unit, and the side air inlet is connected to the fresh air inlet of the translational heat recovery unit. When the exhaust fan is working, indoor air is exhausted outward, and hot air is exhausted to the left side of the recovery unit. The heat will be transferred to the right side of the recovery unit. When fresh air passes through the right side of the recovery unit and enters the circulating air duct, it absorbs heat, thereby cooling the exhausted air and warming the incoming fresh air. The exhaust port is located at the air inlet of the main unit's evaporator, so all the exhausted air is drawn into the evaporator, improving the evaporation efficiency and increasing the heating efficiency of the main unit.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. In short, if a person skilled in the art is inspired by it and designs a similar structure and embodiment without departing from the general concept of the present utility model, it shall fall within the protection scope of the present utility model.
