Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to an air purification heat source recovery and utilization system. Background Technology

[0002] In the modern pharmaceutical manufacturing industry, cleanroom air conditioning systems play a crucial role in maintaining a clean production environment. Currently, most pharmaceutical workshop cleanroom air conditioning systems operate in a traditional mode, where fresh air is cooled and humidified before being delivered to various workshop areas to provide cool air and meet the temperature control requirements of different areas.

[0003] However, pharmaceutical workshops include buffer rooms, solution preparation rooms, sterilization rooms, and cleaning rooms. These workshops are equipped with functional equipment; for example, sterilization rooms contain sterilization cabinets and ovens, and cleaning rooms contain cleaning machines. This equipment generates significant heat during normal operation, requiring the workshop's air supply to operate at high power to meet the required temperature. Furthermore, if this waste heat is directly discharged, the temperature can reach as high as 300°C, which is insufficient to meet the workshop's temperature control requirements.

[0004] Therefore, the heat emitted by the equipment in these pharmaceutical workshops not only affects the air conditioning supply in the workshops, but also cannot be fully recovered, resulting in significant heat loss and poor energy-saving effect of the purification air conditioning system. Utility Model Content

[0005] In view of the above-mentioned shortcomings, this utility model provides a purification air conditioning heat source recovery and utilization system, which can fully dissipate heat from the equipment in the pharmaceutical workshop, thereby improving the working efficiency of the equipment, without affecting the indoor air supply in the workshop, and can also recover and utilize the waste heat after the equipment dissipates heat.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] A heat source recovery and utilization system for a cleanroom air conditioner includes a cleanroom air conditioner, which includes a fresh air handling unit and a chiller unit, and also includes a waste heat recovery module. The chiller unit is connected to a heat-generating device. The waste heat recovery module includes an open absorption heat pump system, a heat storage chamber 24, and a waste heat collection pipe 25. The heat storage chamber 24 includes a heat storage chamber inlet and a heat storage chamber outlet. One end of the waste heat collection pipe 25 is connected to an exhaust vent, and the other end is connected to the heat storage chamber inlet. The open absorption heat pump system is installed between the heat storage chamber outlet and the fresh air handling unit.

[0028] In practical applications, the open-loop absorption heat pump system is an internally cooled vapor compression-open-loop absorption heat pump system. Specifically, such as... Figure 2As shown, the open absorption heat pump system includes a generator 1 and an absorber 2. Both the generator 1 and the absorber 2 have open bottom structures, and a spray device 9 can be installed inside the absorber 2 and the generator 1. A circulation pipe is provided between the absorber 2 and the generator 1, and a heat exchanger 5 and a pump 6 are installed on the circulation pipe to circulate the absorption solution between the absorber 2 and the generator 1. The open absorption heat pump system also includes a throttling valve 3 and a compressor 4. A condenser 7 is installed inside the generator 1, and an absorption heat exchanger 8 is installed inside the absorber 2. The compressor 4, the absorption heat exchanger 8, the throttling valve 3, and the condenser 7 are connected in series.

[0029] In practical applications, the air conditioning fresh air handling unit can be a conventional design in this field. Specifically, it can be as follows: Figure 3 As shown: The air conditioning fresh air handling unit includes a fresh air inlet 10, a fresh air outlet 17, and further includes a fresh air filter, a fresh air mixing device 11, a surface cooler 12, a steam heater 13, a humidifier 14, a fan 15, and a flow equalizer 16 connected in sequence. The fresh air filter is connected to the fresh air inlet 10, and the flow equalizer 16 is connected to the fresh air outlet 17. The surface cooler 12 is connected to a chilled water supply pipe 21, a chilled water return pipe 22, and a condensate pipe 20. The steam heater 13 and the humidifier 14 are respectively connected to a saturated steam inlet pipe 19 and a steam condensate outlet pipe 18.

[0030] In practical applications, the generator 1 includes a first inlet and an exhaust port, the absorber 2 includes a second inlet and an air outlet, the heat storage chamber outlet is connected to the first inlet, the second inlet is connected to fresh air, and the air outlet is connected to a fresh air filter.

[0031] In practical applications, the chiller unit is connected to the heating equipment, which can be a sterilizer 31, a washing machine 32, a bottle washing machine 29, or an oven 28, etc., within the workshop. During operation, a portion of the chilled water from the chiller unit is sent to the heating equipment to cool it and reduce its heat dissipation temperature. After the equipment is cooled, the residual heat still reaches approximately 25-40°C. This heat is collected in the heat storage chamber 24 through the equipment's exhaust vents, the waste heat collection pipe 25, and the exhaust fan 15.

[0032] During operation, hot air in the heat storage chamber 24 enters the generator 1 through the heat storage chamber outlet and the first inlet, where it exchanges heat with the refrigerant in the internal condenser 7. The refrigerant absorbs heat from the air inside the generator 1 and heats up. The heated refrigerant then passes through the throttle valve 3 for depressurization and cooling. The cooled refrigerant enters the absorber 2. Inside the absorber 2, a portion of the fresh air entering from the fresh air inlet 10 of the fresh air handling unit enters the bottom of the absorber 2 through the second inlet. The cooled refrigerant again exchanges heat with the fresh air, absorbing heat from the fresh air and lowering its temperature, thus achieving the cooling purpose. After being cooled by the absorber 2, the air flows out from the air outlet and enters the fresh air filter and mixing chamber along with the remaining fresh air. This fully utilizes the waste heat, improving the cooling effect of the fresh air at the surface cooler 12, thereby improving the overall cooling effect of the fresh air handling unit. Simultaneously, the refrigerant re-enters the generator 1 through the compressor 4 for the next round of heat exchange.

[0033] In practical applications, to prevent excessive air pollution within the heat storage chamber 24, an air purification and sterilization component is installed at the connection between the waste heat collection pipe 25 and the heat storage chamber inlet. Specifically, the air purification and sterilization component can be a HEPA filter, which can filter out fine particulate matter in the air, including bacteria, viruses, dust, etc., ensuring that the air entering the heat storage chamber 24 is clean.

[0038] During operation, air from the heat storage chamber 24 enters through the heat storage chamber outlet and connects to the first inlet, exchanging heat with the refrigerant in the internal condenser 7. The refrigerant absorbs heat from the air inside the generator 1 and heats up. The heated refrigerant then passes through the throttle valve 3 for depressurization and cooling. The cooled refrigerant enters the absorber 2. Inside the absorber 2, a portion of the fresh air entering from the fresh air inlet 10 of the fresh air handling unit enters the bottom of the absorber 2 through the second inlet. The cooled refrigerant again exchanges heat with the fresh air, absorbing heat from the fresh air and lowering its temperature, thus achieving the cooling purpose. After being cooled by the absorber 2, the air flows out from the air outlet and enters the fresh air filter and mixing chamber along with the remaining fresh air. This fully utilizes the waste heat, improving the cooling effect of the fresh air at the surface cooler 12, thereby improving the overall cooling effect of the fresh air handling unit. Simultaneously, the refrigerant re-enters the generator 1 through the compressor 4 for the next round of heat exchange.

[0039] In practical applications, an electric damper is installed on the waste heat collection pipe 25, which can adjust the air volume in real time according to system requirements to improve waste heat collection efficiency.
