However, various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. Furthermore, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, the specific shape, construction and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the technical idea of the present application.

Referring to fig. 1, a heat energy utilization system 100 for a saccharification plant for reducing the ambient temperature of the packaging and saccharification plant and recovering air heat energy by co-generation of heat and cold using an air source heat pump unit according to an embodiment of the present application is shown.

The heat energy utilization system 100 is adapted to be arranged in a saccharification plant and comprises an air supply device 1, an air source heat pump unit 2, a first water tank 3 and a second water tank 4.

As shown in fig. 2, the blower device 1 has a pair of suction pipes 11 and an airflow mixer 12 arranged around the respective mashing pan 200. The air flowing into the air flow mixer 12 from the pair of air suction pipes 11 is mixed at the air flow mixer 12 to achieve mixing. One end of each air suction pipe 11 is provided with an air collecting cover 13; in this example, the air collection hood 13 is horn-shaped and is disposed around the masher pan 200.

The airflow mixer 12 includes a square-shaped housing 121, a pair of sleeves 122 located inside the housing 121 and disposed opposite each other, and an air outlet duct 123 extending outwardly from the housing 121. A pair of sleeves 122 respectively interface with and are in air flow communication with a pair of aspiration channels 11; the outlet duct 123 is in fluid communication with the pair of sleeves 122 simultaneously, i.e., the air streams entering the air flow mixer 12 from the pair of sleeves 122 will mix and simultaneously flow outwardly from the outlet duct 123. The pair of suction pipes 11 is preferably flexible and stretchable.

As shown in fig. 4, a valve plate 124 for controlling the fluid penetration of the inside of the sleeve 122 is provided inside each sleeve 122; when the valve plate 124 is opened, the interior of the sleeve 122 is communicated with fluid, and air can flow to the air outlet pipe 123 through the sleeve 122; when the valve plate 124 is closed, the passage inside the sleeve 122 is blocked, and air is prevented from flowing from the sleeve 122 to the air outlet pipe 123.

The air flow mixer 12 further comprises a pair of tie rods 125 exposed outside the casing 121, each tie rod 125 being in driving connection with a respective valve plate 124; each of the tie bars 125 is configured to be operable by a user so that the user can control whether the corresponding suction duct 11 sucks in air around the corresponding mashing pan 200 according to the actual operation of the mashing pan 200.

In other embodiments, the air flow mixer 12 may be provided with a greater number of aspiration ducts, which may be selected according to the number of saccharification pots in the saccharification plant.

As shown in fig. 4, the air supply device 1 is supported on a supporting frame 5 which can be lifted up and down, and the supporting frame 5 can be used for adjusting the height to be proper according to the requirement; the support 5, the first water tank 3 and the second water tank 4 of the present example are simultaneously installed on a movable base 6; by means of the base 6, the installer can carry the remaining components other than the air source heat pump unit 2 to any suitable location depending on the location of the mashing pan 200.

As further shown in fig. 1, the air-source heat pump unit 2 includes an evaporator 21, a condenser 22, an expansion valve 23, a compressor 24, an air flow passage 25, and a heat recovery pipe 26. The condenser 22, the expansion valve 23, the evaporator 21 and the compressor 24 are sequentially in fluid communication and constitute a refrigeration cycle system through which a refrigerant circulates; after being compressed by the compressor 24, the refrigerant enters the expansion valve 23 to expand after heat exchange with the fluid medium in the heat recovery pipeline 26 through the condenser 22, then enters the evaporator 21 to evaporate, and then enters the compressor 24 again.

The inlet side of the air flow channel 25 is in fluid communication with the outlet pipe 123 of the air flow mixer 12, the outlet side being exposed to the environment of the saccharification plant. The air flow passage 25 is configured to pass through the evaporator 21, and the heat recovery pipe 26 is arranged to flow through the condenser 22.

The refrigerant medium exchanges heat with the air in the air flow path at the evaporator 21, that is, absorbs heat in the air, so that the air temperature is reduced and sent out from the air outlet side. In this example, the fan 27 is provided on the inlet side of the air flow path 25, and the high-temperature air around the mashing pan 200 is continuously sucked from the suction pipe 11 and flows from the inlet side to the outlet side by the work of the fan 27.

The heat recovery conduit 26 is capable of providing a heat exchange medium for heat exchange with the refrigerant medium flowing through the condenser 22. In this example, the first water tank 3 stores water at a relatively low temperature, the second water tank 4 stores water heated by the condenser 22, and the heat recovery pipe 26 has one end in fluid communication with the first water tank 3 and the other end in fluid communication with the second water tank 4. The heat recovery pipe 26 is configured to allow the water in the first water tank 3 to be fed into the second water tank 4 after absorbing heat through the condenser 22.

In the heat energy utilization system of the present application, it is also necessary to provide a controllable valve member and a temperature detecting member in each path, on the basis of which the air source heat pump unit 2 can perform parameter adjustment for operation at optimum efficiency.

The heat energy utilization system realizes heat recovery through the air source heat pump unit 2, and the environmental temperature is maintained at about 40 ℃ due to the huge heat emitted by the saccharification pot 200, so that the air source heat pump unit 2 works under the temperature condition to obtain a higher heating performance coefficient (namely COP value); the air source heat pump unit 2 can raise the temperature of low-temperature water (such as 75 ℃ water) from the first water tank 2 to high-temperature water (such as 90 ℃) by absorbing heat in the surrounding environment of the saccharification pot 200 and store the low-temperature water into the second water tank 4 for production and use, and the heat of the saccharification pot is recovered by the process, so that the energy-saving and environment-friendly requirements are met.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
