Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to an air conditioning system for utilizing waste heat and waste cooling in the air conditioning room of an industrial plant. Background Technology

[0002] With the large-scale extraction of fossil fuels and the continuous rise in oil and coal prices, and in response to the national call to reduce carbon emissions, making full use of solar energy clearly has the dual significance of sustainable development and energy conservation and emission reduction. The vigorous promotion of solar energy technology has greatly alleviated energy problems and environmental pollution problems.

[0003] With the rapid development of Chinese society, people are increasingly demanding higher quality indoor environments. Air conditioning is no longer limited to cooling in summer; higher standards are being set for environmental protection, health, and comfort. Building energy consumption accounts for about one-third of my country's total energy consumption, primarily for heating and cooling. Especially in summer, the huge cooling demand often consumes large amounts of conventional energy, even leading to power shortages during peak hours, posing a severe challenge to the power supply. Solar cooling technology can effectively alleviate power load during peak summer periods, aligning with the basic principle of coordinated energy and environmental development. It helps mitigate global energy shortages, ozone layer depletion, and climate change, making building energy conservation a crucial aspect of building energy conservation and emission reduction.

[0004] However, refrigeration systems account for the largest proportion of building energy consumption. Moreover, the low-temperature condensate and high-temperature steam condensate generated by the air conditioning units in the air conditioning rooms of industrial production plants are directly discharged. Furthermore, existing refrigeration systems generally rely on electrically driven compression refrigeration, which uses refrigerants such as Freon, posing a risk of damaging the ozone layer and exacerbating global warming, resulting in energy waste and environmental pollution.

[0005] Therefore, there is an urgent need for a new technology that can solve the problems of energy waste and environmental pollution. Utility Model Content

At the same time, the air conditioning unit's cooling condensate water is introduced into the outer casing of the condenser for cooling, which not only avoids the direct discharge of low-temperature condensate water and causes environmental pollution, but also uses the waste cooling resources contained therein to improve the refrigeration efficiency, realizing the efficient conversion of low-grade energy. The evaporator outlet and the adsorption bed form a circulation through the waste cooling recovery unit, further recovering the unused cooling capacity in the system, reducing energy waste overall. This system not only alleviates the problems of high energy consumption and large emissions of industrial plant air conditioning systems, but also reduces operating costs through the cascade utilization of energy, providing reliable technical support for green and low-carbon production.

[0019] In some embodiments, a hot water pump effectively transports the high-temperature condensate from the steam humidification condensate tank of the air conditioning unit to the adsorption bed, realizing the targeted recovery and utilization of high-quality waste heat in industrial plants. This transforms the originally directly discharged high-temperature condensate into a highly efficient driving heat source for adsorption refrigeration, significantly reducing the system's dependence on external energy and reducing energy consumption from steam or electric heating. At the same time, this unit avoids the direct discharge of high-temperature condensate from the source, preventing thermal pollution from affecting the surrounding environment and improving the overall energy utilization efficiency of the entire air conditioning system, achieving the dual benefits of energy saving and environmental protection.

[0020] In some embodiments, the cooling capacity distribution unit is connected to the evaporator via a chilled water tank and circulated using fan coil units, constructing a highly efficient and stable cooling capacity distribution system. The cooling capacity generated by the adsorption refrigeration unit is preferentially stored in the chilled water tank, achieving peak shaving and valley filling of cooling capacity, effectively improving the system's ability to cope with load fluctuations. Subsequently, the cooling capacity is precisely distributed to the required areas of the plant through fan coil units, significantly enhancing the uniformity and stability of the cooling effect. The entire unit not only avoids energy waste caused by supply and demand mismatch in traditional systems, but also greatly improves the utilization efficiency of waste cooling resources, reducing the operating energy consumption of the entire air conditioning system while ensuring the requirements of the process environment.

The pump inlet is connected to the steam humidification condensate tank of the air conditioning unit, and the pump outlet is connected to the high-temperature condensate inlet 18 of the adsorption bed 1.

[0036] In some embodiments, the waste cooling recovery unit includes a second vacuum valve 9, and the evaporation outlet is connected to the refrigerant port of the adsorption bed 1 through the second vacuum valve 9.

[0042] The structure and working principle of this utility model will be further explained below: The purpose of this utility model is to provide an air conditioning system for utilizing waste heat and waste cold in the air conditioning room of an industrial plant. When using this device, first turn on the hot water pump 6 and open the hot water valve 8. The high-temperature condensate in the steam humidification condensate tank of the air conditioning unit is sent to the outer box of the adsorption bed 1 through the high-temperature condensate inlet 18 via the hot water pump 6, where it exchanges heat with the adsorption bed 1, heating the adsorption bed 1. The adsorption bed 1 desorbs the refrigerant vapor by absorbing the heat from the high-temperature condensate. The high-temperature condensate after heat exchange is discharged into the floor drain through the high-temperature condensate outlet 19 via a pipe.

[0043] Then, turn on the water pump connected to the outer casing of condenser 2, open the throttle valve 11, open the first vacuum valve 10, and close the second vacuum valve 9. The low-temperature condensate in the cooling condensate tank of the air conditioning unit is pumped into the outer casing of the condenser through the second inlet 14 of the outer casing of the condenser to exchange heat with the refrigerant vapor inside the condenser body. After heat exchange in the condenser body, the refrigerant vapor condenses into liquid, and then passes through the throttle valve 11 and is finally stored in the evaporator 3.

[0044] Finally, open the cold water pump 7 and the second vacuum valve 9, close the hot water pump 6 and the water pump in the outer casing of the condenser 2, close the throttle valve 11 and the first vacuum valve 10, and close the hot water valve 8. After the adsorption bed 1 is cooled, the refrigerant evaporates and absorbs heat in the evaporator 3, and then exchanges heat with the chilled water in the chilled water tank 4. The chilled water after heat exchange is sent to the fan coil unit 5 through the cold water pump 7. The chilled water flows in the fan coil unit 5. After the return air of the fan coil unit 5 exchanges heat with the fan coil unit 5, the cold air is sent into the room through the air outlet 17 to cool the indoor air, thereby achieving indoor cooling.

[0045] This invention utilizes the low-temperature condensate and high-temperature condensate generated by industrial air conditioning units for heat exchange to complete the refrigeration process. This eliminates the need for large energy consumption for indoor refrigeration, prevents the generation of chlorofluorocarbons (CFCs) during the refrigeration process, and avoids environmental pollution. Furthermore, this application realizes the use of waste heat and cold generated in industrial production for refrigeration, minimizing the use of electrical energy and reducing energy losses in the original refrigeration process in industrial production. This reduces energy consumption in industrial production, effectively utilizes the waste heat and cold emitted indiscriminately during daily operations, and increases the profits of industrial production.

[0046] This invention combines adsorption refrigeration with indoor air conditioning to design a refrigeration and air conditioning system that controls the temperature and humidity of indoor areas. Therefore, it can effectively utilize the waste heat and cold generated by industrial air conditioning units to achieve energy saving and comfort. The system uses less electricity, saves traditional energy, and has almost no environmental harm compared with traditional air conditioning. It is highly targeted and has a high energy utilization rate. This invention organically combines adsorption refrigeration with the utilization of waste heat and cold, achieving the goal of green refrigeration and sustainable development.
